    3.181 Fall and Rise of China: Soviet Counter Offensive over the Heights Dec 22, 2025
    Show notes

    Last time we spoke about the Japanese Victory over Changkufeng. Japan's generals hatched a plan: strike at night, seize the peak, then bargain if need be. Colonel Sato, steady as a compass, chose Nakano's brave 75th Regiment, selecting five fearless captains and a rising star, Nakajima, to lead the charge. Ahead, scouts and engineers threaded a fragile path through darkness, while distant Soviet tanks rumbled like distant thunder. At 2:15 a.m., wire breached and soldiers slipped over the slope. The crest resisted with brutal tenacity, grenades flashed, machine guns spit fire, and leaders fell. Yet by 5:15 a.m. dawn painted the hill in pale light, and Japanese hands grasped the summit. The dawn assault on nearby Hill 52 and the Shachaofeng corridor followed, with Takeshita's and Matsunobe's units threading through fog, fire, and shifting trenches. Narukawa's howitzers answered the dawn with measured fury, silencing the Soviets' early artillery as Japanese infantry pressed forward. By daybreak, the Russians were driven back, their lines frayed and retreating toward Khasan. The price was steep: dozens of officers dead or injured, and a crescent of smoke and memory left etched on every face. #181 The Russian Counter Offensive over the Heights Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. After admitting the loss of Changkufeng and Shachaofeng by dawn on 31 July, the Russian government issued a communique the next day asserting that Soviet troops had "hurled back a Japanese division… after a two-day battle" involving tanks, artillery, and aircraft. Some hours after the Japanese penetration, Soviet regulars rushed to the scene and drove out the invaders. Japanese losses amounted to 400 men; Soviet losses were 13 killed and 55 wounded. On Soviet soil, the Japanese abandoned five cannons, 14 machine guns, and 157 rifles, while the Russians admitted losing one tank and one gun. A Soviet reconnaissance pilot may have fallen into Japanese hands after bailing out. "Both before and during the Japanese attack… Soviet troops did not once cross the Manchukuoan frontier,which deprived them of the possibility of surrounding or outflanking the invaders." By 1 August, Russian ground forces were deployed and the Soviet Air Force took action. Soviet aircraft appeared at 24:30 to reconnoiter. Soon after, more than ten planes flew in formation, launching strikes against forward units. Eight sorties, light bombers and fighters, roughly 120–150 aircraft in flights of two or three dozen, bombed and strafed. Raids were conducted by as many as 30 planes, though no Soviet losses were reported. The Russians also hit targets on the Korean side of the Tumen. The 75th Regiment judged that the Soviet Air Force sought only to intimidate. Russian planes dropped several dozen bombs on the Kyonghun bridge, but the span was not struck; damage was limited to the railway, producing an impression of severity that was misleading. The lack of air cover troubled the troops most. Japanese casualties on 1 August were modest: three men wounded in the 75th Infantry, and one wounded and a horse killed in the 76th. However the three Japanese battalions expended over 15,000 machine-gun and 7,000 rifle rounds that day. The appearance of Soviet air power at Changkufeng drew anxious international attention. Shanghai reports electrified observers, who anticipated that major Russo-Japanese hostilities would transform the China campaign overnight. Some observers were openly dismayed, foreseeing a prolongation of the mainland war with potential benefits to Soviet interests. Japanese Army spokesmen sought to downplay the situation. Officers in Hsinking told correspondents that the raids, while serious, represented only a face-saving measure. The Red Army was reportedly attempting to compensate for losses at Changkufeng and other disputed positions, but aside from the bombings, the frontier remained quiet. If the Russians were serious, observers noted, they would have bombed the vital Unggi railway bridge, which remained untouched; raids focused on minor bridges, with limited damage. In Tokyo, foreign observers believed the appearance of about 50 Soviet heavy bombers over North Korea signaled an extension of the incidents and that the Japanese government was taking urgent measures. Military leaders decided not to escalate but prepared for emergencies. The Korea Army Headquarters denied Soviet bombing of Harbin in Manchuria or Najin and Chongjin in Korea. Regarding retaliation, an American correspondent reported that the Japanese military had no intention of bombing Russian territory. Although Soviet use of aircraft introduced a new dimension of danger, the main efforts remained ground-based on both sides. After Japanese troops cleared Changkufeng and Shachaofeng, the Russians appeared to be redeploying to contract their defensive frontage; no troops or works remained west of Khasan. Four or five Russian infantry companies and ten artillery pieces stood between the lake and Paksikori, while the main forces, with numerous gun sites, were concentrated west of Novokievsk. On the Kwantung Army front in southeast Manchuria, no changes were observed. "The Russians were apparently shocked by their defeat at Changkufeng and must suddenly have resorted to negative, conservative measures." Korea Army Headquarters assessed the situation as of the evening of 31 July: "The enemy must fear a Japanese advance into the Novokievsk plain and therefore is concentrating his main forces in that district. Our interests require that we anticipate any emergency, so we must prepare the necessary strength in the Kyonghun region and reinforce positions at Wuchiatzu." At 20:45 on the 31st, the 19th Division received a detailed message from the Hunchun garrison commander describing his northward deployments. Suetaka was heartened; he "earnestly desired to bring about the end of the incident as a result of the fighting of 30–31 July but was equally resolved to defend the border firmly, based on Japanese interpretation of the Hunchun pact, in case the Soviet side did not perform intensive self-reflection." First, Suetaka issued instructions from Kyonghun at 8:15 on the 31st via K. Sato: "It is our intention that Changkufeng and the high ground northwest of Shachaofeng be secured, as well as the high ground south of Shachaofeng if possible. Enemy attacks are to be met at our positions, but you are not to pursue far." Second, Colonel Tanaka was instructed not to fire as long as Russian artillery did not bombard friendly forces. "Except for preparing against counterassaults, your actions will be cautious. In particular, harassing fire against inhabited places and residents is prohibited." Suetaka was finally armed with formal authority, received at 22:05 on 1 August. He did not delay in implementing it. At 23:00 he ordered the immediate rail movement of strong reinforcements: the alerted infantry brigade headquarters, as well as four infantry battalions and the remaining mountain artillery battalion. Thus, Suetaka could deploy forward not only the forces he had requested but also a brigade-level organization to assume control of the now sizeable combat elements massed at the front for "maneuvers." Earlier that afternoon he had already moved his division's message center forward to the Matsu'otsuho heights at the Tumen, and he regularly posted at least one staff officer there so that the center could function as the division's combat headquarters. An additional matter of explosive potential was built into the divisional order: provision of Japanese Air Force cover for rail movements forward, although use of aircraft had been prohibited by all higher headquarters; Nakamura intended only ground cover. At the front, Japanese units spent most of their time consolidating their hard-won positions. By 3 on 1 August, a column of Soviet forces with vehicles was observed moving from the east side of Khasan. Late in the day, the division received an extremely important telegram from the 2nd (Intelligence) Section of the Kwantung Army: "According to a special espionage report from our OSS in Khabarovsk city, Red Army authorities there have decided to retake the high ground along Changkufeng." From other intelligence, the Kwantung Army concluded that the Russians were rebuilding in the Novokievsk region. Frequent movements observed immediately to the rear of the Soviet battle zone caused K. Sato to grow apprehensive about a dawn counterattack on the 1st, and he reinforced Changkufeng with the 6th Company. The second of August was marked by continuation of Soviet air attacks and the anticipated Russian counteroffensive. According to Japanese intelligence, Marshal Blyukher had arrived in Khabarovsk, and Lieutenant General Sokolov was in Voroshilov. An offensive buildup, estimated at about 3,000 men plus tanks and guns, was reported in the Kozando area by evening on the 1st. Hirahara, commanding the battalion at Changkufeng, grew concerned about Hill 52. With day's end approaching, he reinforced the defenses further and ordered the battalion medical officer to establish a dressing station at Fangchuanting. Around 15:00 Soviet artillery began firing at forward areas, especially gun positions; the bombardments were described as severe. Japanese artillery sought to conserve ammunition, firing only at worthwhile, short-range targets. Main Russian ground actions focused on the far-right (Hill 52) and far-left (Shachaofeng) sectors, not Changkufeng. In line with Hirahara's orders, two infantry companies and four heavy machine guns were moved by 8:00 from Changkufeng to the heights 800 meters southeast. Soviet heavy artillery pounded the zone between Fangchuanting and Hill 52; observing the enemy became difficult. Russian planes engaged at 9:00 fighters, then bombers, to soften defenses and gun positions. Meanwhile, the Soviets deployed firepower southeast of Khasan, while two infantry battalions and more than ten tanks advanced through the pines on the western slopes. Japanese regimental guns and two machine-gun platoons at Hill 52 attacked the enemy heavy machine guns and neutralized them. By 10:00 the Russians had advanced with heavy weapons to the high ground 800 meters from Hill 52. From Changkufeng, the battalion guns engaged heavy weapons. Hirahara moved with the engineers and battalion guns to the heights to which he had transferred reinforcements earlier, took command, and prepared an assault. Initially, Soviet troops advanced in formation, but after cresting a dip, they dispersed and moved onto the high ground opposite Hill 52. Heavily armed, they drew within 700 meters, with artillery and heavy machine guns providing coverage. By 10:00 Sato requested Shiozawa's mountain guns across the Tumen to unleash a barrage against Hill 52's front. For about half an hour, the battery fired. By 10:30, the Soviet advance grew listless. Believing the moment ripe, Hirahara deployed his men to charge the foe's right wing, ordering rapid movement with caution against eastern flank fire. On the heights north of Hill 52, Inagaki watched the struggle; with the telephone out and the situation urgent, he brought up firepower on his own initiative. Taking the main body of the 1st Machine Gun Company, along with the battalion guns, he moved out at noon, making contact with the 10th Company on Hill 52 around 14:00, where the Japanese machine guns and battalion guns joined the fray. The Russians, losing momentum, were checked by Japanese heavy weapons and by mountain guns from Hill 82. Hirahara's main battalion advanced onto the high ground north of Hill 52 around noon. By 15:00, two enemy companies began to fall back, climbing the western slopes of Hill 29 as the main forces retreated piecemeal to a dip. By 16:00, Suetaka observed that his units were continuing to secure their positions and were "gradually breaking the hostile intention." Despite heat and rain, front-line troops showed fatigue but remained vigilant. Between 11:00 and 16;00, Sato inspected the lines and directed defensive positions, particularly at Hill 52. After a poor initial performance, the Russians awaited reinforcements before attempting another assault on Hill 52. They moved up a mechanized corps, and by 15:00 50 tanks massed east of Maanshan. Around 17:00, the Russians began moving south along the high ground across Khasan. Another two Soviet battalions advanced along the Tumen hills, led by armor. Hirahara anticipated an assault at twilight, especially after 18:00, when nine bombers struck Hill 52. Earlier, Takeshita had received reports from the antitank commander, Lieutenant Saito, that at 17:00 several enemy tanks and three infantry battalions were advancing from Hill 29. Convinced of an imminent Soviet strike, Takeshita ordered the defense to conceal its efforts and to annihilate the foe with point-blank fire and hand-to-hand fighting. He sought to instill confidence that hostile infantry could not reach the positions. Before 19:00, the enemy battalions came within effective range, and Japan opened with all available firepower. Rapid-fire antitank guns set the lead tank alight; the remaining tanks were stopped. Support came from Hisatsune's regimental guns and two antitank gun squads atop Changkufeng. The Russian advance was checked. By nightfall, Soviet elements had displaced heavy weapons about 400 meters from Japanese positions. As early as 16:00, Suetaka ordered a mountain artillery squad to cross the river. Sato told Takeshita at 7:30 that there would be a night attack against Hill 52. Takeshita was to annihilate the foe after allowing them to close to 40–50 meters. The Russians did mount a night assault and pressed close between 8 and 9 p.m. with three battalions led by four tanks. The main force targeted Takeshita; all ten Russian heavy machine guns engaged that side. Japanese machine guns and battalion guns joined the fray. The Russians pressed within 30 meters, shouted "Hurrah! Hurrah!" and hurled grenades before advancing a further 15 meters. The Japanese repelled the first waves with grenades and emplaced weapons, leaving light machine guns and grenade dischargers forward. Soviet illuminating shells were fired to enable closer approaches within 100 meters. Japanese grenade-discharger fire blasted the forces massed in the dead space before the works. While the Hill 52 night attack collapsed, other Russian units, smaller in strength and with one tank leading, moved against the hill on the left that the Japanese had not yet occupied that morning. The Russians advanced along the Khasan slope north of Hill 52, came within point-blank range, and shouted but did not charge. By 22:00, the Japanese, supported by machine guns, had checked the foe. Thereupon, the 6th Company, now under a platoon leader, Narusawa, launched a counterattack along the lake. "The enemy was bewildered and became dislocated. Buddies were heard shouting to one another, and some could be seen hauling away their dead." The Soviet troops held back 300–400 meters and…

    3.180 Fall and Rise of China: A premature Japanese Victory over Changkufeng Dec 15, 2025
    Show notes

    Last time we spoke about the battle over Changfukeng Hill. In the frost-bit dawn by the Chaun and Tumen, two empires faced a cliff of fate: Soviet and Japanese, each convinced that Changkufeng belonged to them. Diplomats urged restraint, yet Tokyo's generals brewed a daring plan, strike at night, seize the crest, then bargain. Sato and Suetaka debated risk and restraint, weighing "dokudan senko" against disciplined action as rain hissed on the ground. Night fell like velvet. Nakano, a quiet, meticulous regimental leader, gathered the 75th Regiment's veterans, choosing five fearless captains and a rising star, Nakajima, to carry the charge. Scouts and engineers moved ahead, weaving a fragile path across the Tumen: wire-cutters in the dark, signals humming softly, and the thunder of distant Soviet tanks rolling along the shore. At 02:15, after breaches breached and silent men slid through wire, the Japanese surged up the slopes with bayonets glinting, swords ready, and nerves as taut as steel. The crest lunged with savage resistance: grenades flashed, machine guns roared, and leaders fell. By 05:15, dawn broke, and the hill, Course of blood and courage, stood in Japanese hands. #180 A premature Japanese Victory over Changkufeng Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. On 31 July 1938, dawn seemed to indicate Changkufeng Hill was in Japanese hands. From his command post, Colonel Sato Kotoku, his regimental staff, and most of Hirahara's 3rd Battalion had been anxiously watching the progress of the 1st Battalion's operations since 12:30 on 31 July. Around 03:00, the Japanese infantry commanders issued "heroic orders to charge," audible above the withering fire. Sato expected the crest to fall in little more than an hour; when no signal shell burst over the hill, he grew apprehensive, praying for success with his heart breaking. A mile away on Hill 52, the troops could discern no voices, only gunfire and the spectacular glow of flares and tracers. As one soldier recalled "It was like fireflies," another soldier added "it was like a carnival". To Sasai, on the heights at Kucheng, it was, as he put it, "c'était un grand spectacle." By the way I think its one of the only times I've read a Japanese soldier using French, what he said translates to "it was a large spectacle", I am from Quebec so I speak baguette. The mist moved up Changkufeng Hill, and Japanese troops followed it, fighting for hours. Fearing Nakano's battalion might have been wiped out, Sato's staff prayed for fog. Sato later admitted, "By dawn we were failing to take our objectives." At the base of Chiangchunfeng, Sato held the 6th Company in reserve, ready to attack Changkufeng from the left. He would have preferred not to commit it, given the danger of an accidental fire-fight with friendly forces. Nevertheless, as combat intensified, Sato decided to push the company into support of the 1st Battalion. After orders at 03:15, Ito moved toward the northwest side of Changkufeng. The Russians laid down heavy fire, especially from a well-placed machine-gun position on the far left. Ito's company, suffering heavy and needlessly casualties, had to hold near the middle of the slope. A runner was sent to the regimental command post requesting artillery support after dawn. By 04:30, Sato could discern the Changkufeng crest, where fierce close-quarters fighting raged between Japanese and Russians on the south edge, while the enemy continually sent reinforcements, troops followed by tanks, up the northern slope. Ito's company was visible on the western slope, bravely bearing a Japanese flag. 10-15 minutes later, grenade-discharger fire began to blast the Soviet positions. At 04:40, Ito, redeploying at dawn, observed elements of the 1st Company near the hill's summit. Contact was established with Inagaki's men. The Russians began to show signs of disarray under the grenade dischargers and the heavy weapons deployed by the reserve battalion at Chiangchunfeng. Thereupon Ito's company charged as well, capturing the northwest corner of Changkufeng roughly concurrently with the main body of the 1st Battalion under Sakata. Ito was wounded and evacuated; two sergeants were later cited in dispatches. Meanwhile, the 10th Company, led by Takeshita of the 3rd Battalion, was to conduct a separate night assault against fire points around Hill 24, about 1,000 meters north of Changkufeng. The aim was to disrupt Russian withdrawal along the slopes to the rear and to hinder reinforcements. At midnight, the company left the skirts of Chiangchunfeng in fog and darkness. Moving stealthily over the undulating terrain, they faced knee-deep bogs and tall vegetation. After evading sentries, they penetrated behind the enemy. By 02:00, five teams totaling 16 men under Sergeant Uchibori were ready to strike Hill 24. Takeshita led the charge from the right and overran the defenders by 02:20. The Russians, numbering 20 to 30 riflemen with one machine gun, fled toward Khasan, leaving four soldiers behind whom the Japanese bayoneted. Takeshita's company continued to consolidate Hill 24, awaiting counterattacks, which soon followed. At 04:00, eight tanks, with headlights on, launched an attack from the Shachaofeng sector, supported by an infantry company . Takeshita reinforced Uchibori's unit with assault teams; the Russian infantry were routed, and five tanks were knocked out. At dawn, about 100 Soviet troops were observed retreating from the direction of Changkufeng, surprised and mowed down by heavy and light machine guns at ranges of about 300 meters. At 06:30, the Soviets attacked again with an infantry battalion and a machine-gun company from north of Khasan. The Japanese allowed them to close, then concentrated the firepower of both infantry platoons plus heavy machine guns. After a 30-minute firefight with heavy casualties on the Soviet side, the Russians fell back. Again, at 07:10, the Soviets struck from the north of Khasan, this time with one company and five tanks. Russian infantry, supported by three tanks, pushed in front of the Japanese positions, but machine-gun and small-arms fire forced them to retreat eastward, the tanks being stopped 50 meters from the lines. Meanwhile, two Japanese enlisted men on patrol near the lake encountered armor; they attacked and, after taking casualties, returned with captured ammunition and equipment. One rapid-fire piece had been providing covering fire behind Takeshita's unit and opened fire on three tanks attacking north of Changkufeng, helping to stop them. As daybreak arrived, Takeshita's company cleared the battlefield, retrieved casualties, and reinforced the defenses. Then an order from the regiment transferred the main body to Changkufeng. Leaving one platoon at Hill 24, Takeshita came directly under Hirahara's command. Takeshita was later officially cited by the regiment. If Hill 52 fell, Changkufeng would be lost. The Russians understood the importance of this constricted sector as well. Their armor could swing south of Khasan, while the terrain to the north was boggier and could be made impassable by the field-artillery battery emplaced on the Korean side of the Tumen. To check hostile reinforcements into this vital region, Sato had dispatched an infantry element to Hill 52 early. Northward, he had 1st Lieutenant Hisatsune emplacement the two 75-millimeter mountain pieces belonging to his infantry gun battery, together with two of 2nd Lieutenant Saito's three 20-millimeter anti-tank guns and the two 37-millimeter infantry rapid-fire guns belonging to 2nd Lieutenant Kutsukake's battalion gun battery. At 23:00 on 30 July, in accord with Nakano's orders, Hisatsune moved these six guns to the ridgeline between Changkufeng and Hill 52. Apart from the guns to the left, defense of Hill 52 was entrusted to the experienced Master Sergeant Murakoshi Kimio, 2nd Platoon leader in Nakajima's company. After the Shachaofeng affair, Murakoshi was ordered to occupy the hill. Moving along the shore on 30 July, his unit encountered neither friendly nor hostile troops. The regimental records note that "some enemy unit came into the dip east of Hill 52 since morning on the 30th, and both sides were watching each other." Murakoshi deployed his three rifle squads, totaling 34 men. After Nakano's battalion jumped off on 31 July, the platoon observed not only the "fireworks display" but also Soviet motorized units with lights aglow, moving on high ground east of Khasan. Later, tanks could be heard clanking toward Hill 52. Around 04:00, Murakoshi organized anti-tank teams and sent them into action. Most accounts emphasize the anti-tank efforts, rather than the fire of Murakoshi's machine gunners. Three privates, carrying anti-tank mines, undertook daring assaults once the terrain obliged the Russian tanks to slow. They laid their mines, but the soil proved too soft, and the attempt failed. In the most publicized episode, Private First Class Matsuo, nicknamed a "human bullet," was badly wounded by machine-gun fire from a tank and knocked from the vehicle, but he managed to reboard with a satchel charge and, it is said, stop the tank at the cost of his life. The platoon leader and his remaining 20 men, having withdrawn 200 meters below their positions, poured torrents of fire at the infantry accompanying the tanks. Flames from the antitank mine assaults provided blazing targets. In concert with Hisatsune's six infantry guns emplaced on the Crestline southeast of Changkufeng, Murakoshi knocked out the remaining two tanks. When the tanks were immobilized, the Soviet troops did not press forward; exposed to Japanese fire, their losses mounted. By daybreak, the Russians had pulled back. Official records describe one Soviet company with four heavy machine guns, led by mounted officers. After hours of intense combat, Colonel Sato and his staff observed that all operations were succeeding by dawn. It was fortunate that Japanese units had posed a threat from the east; only then did the Russians begin to retreat. "But what an incomparably heroic first combat it had been… the scene at Changkufeng was sublime and inspiring. Private feelings were forgotten, and all bowed their heads in respect for the gallant fighting by matchless subordinates." As soon as Sato confirmed that Changkufeng had been occupied, he sent an aide to assess casualties. "When the colonel learned about the death of his capable and dependable officers," a lieutenant recalled, "he… murmured, 'Is that so?' and closed his eyes. The dew glistened on his lids." Meanwhile, in addition to the battle of annihilation at Changkufeng, Major Takenouchi of Okido's regiment was to conduct the dawn assault in the Shachaofeng area. His 1st Battalion and attached elements numbered 379 men; Kanda's company of the Kucheng Border Guard Unit added another 49. An engineer platoon was attached. At 18:00 on 30 July, Takenouchi issued his orders. According to that evening's regimental maps, north of Khasan were two battalions of Soviet infantry and 20 tanks. South of Shachaofeng, the Russians had entanglements and machine-gun nests, with additional emplacements to the rear, west of the lake, and armor moving south toward Changkufeng. Northwest of Shachaofeng lay the main body of Takenouchi's battalion. Signal lines connected his headquarters with Sato's command post. The only Soviet patrol activity noted, as of evening, was in the direction of Matsunobe. Around 02:00, machine guns chattered south of Changkufeng, signaling an increasing intensity of Sato's night assault. On Takenouchi's front, the Russians went on alert, firing illuminating shells and opening fire from the north side of Changkufeng. At 02:30, Matsunobe's unit finished breakfast and moved to the jump-off site. The terrain was difficult and there was considerable enemy tracer fire, but, thanks to effective reconnaissance, the force reached its destination without loss by 04:00. Matsunobe eliminated an outpost unit using rear-area scouts who struck from the rear and gave the enemy little opportunity to respond. Then the Japanese prepared for the main attack as they awaited daybreak. At 04:00, the supporting mountain artillery platoon took position between Matsunobe and Takenouchi. Throughout this period, the sounds of fighting grew more violent toward Changkufeng; machine guns were especially active. At 05:00, three enemy tanks could be seen moving up the northern slope of Changkufeng, but soon after news arrived that friendly forces had seized the crest. With sunrise imminent, the Japanese guns assumed their role. The longest-range support Takenouchi could expect was Narukawa's two 15-centimeter howitzers, emplaced across the Tumen north of Sozan. This battery took position at 04:20, after which the commander went to join Sato just behind the front. Several thousand meters of telephone line had been strung across the river, linking observation post and battery. Narukawa watched the fierce struggle at Changkufeng and prepared to support the dawn assault, while honoring the desperate effort of Ito's company for covering fire. Firing began at 05:10, though range data were not adequate. After little more than ten rounds, the enemy heavy machine guns on the Shachaofeng front subsided. A veteran artilleryman proudly remarked, "These were the first howitzer shells ever fired against the Soviet Army." At 05:20, Takenouchi's own heavy weapons added effective counterfire. Matsunobe and his company had crept to a line 150 meters in front of the Russian positions, taking advantage of dead angles and covered by light machine guns. Three Soviet tanks, however, had pressed forward against the main body. Two Private First Class soldiers, members of a close-quarters team, waited until the lead tank reversed course, then dashed in from the rear and blew it up. Two other soldiers attacked the third tank with mines but could not destroy it because of the tall grass. In a dramatic action that always thrilled Japanese audiences, a Private First Class jumped aboard with a portable mine, while a superior private jammed explosives into the tank's rear and allegedly blew off both treads, though the tank continued firing. While Matsunobe's company laid a smoke screen and prepared to charge, the Soviet tank was knocked out by rapid-fire guns. Master Sergeant Sudo's platoon seized the opportunity to race forward 15 meters and overrun two firing points at 05:40. When the Russians counterattacked with 60 infantrymen and three new tanks, Matsunobe ordered the grenade-discharger squad to fire while he had Sudo pull back to the foot of the hill. Close-quarter teams knocked out the tanks in succession. By this time the Russians had been shaken badly, allowing Matsunobe's main force to surge into two more positions. Five or six remaining Soviet soldiers were wiped out by a combination of Japanese pursuit fire and Soviet gunf…

    3.179 Fall and Rise of China: Lake Khasan Conflict II Dec 08, 2025
    Show notes

    Last time we spoke about the beginning of the battle of lake Khasan. On a frost-bitten dawn by the Chaun and Tumen, two empires, Soviet and Japanese, stared at Changkufeng, each certain the ridge would decide their fate. Diplomats urged restraint, but Tokyo's generals plotted a bold gamble: seize the hill with a surprise strike and bargain afterward. In the Japanese camp, a flurry of trains, orders, and plans moved in the night. Officers like Sato and Suetaka debated danger and responsibility, balancing "dokudan senko", independent action with disciplined restraint. As rain hammered the earth, they contemplated a night assault: cross the Tumen, occupy Hill 52, and strike Changkufeng with coordinated dawn and night attacks. Engineers, artillery, and infantry rehearsed their movements in near-poetic precision, while the 19th Engineers stitched crossings and bridges into a fragile path forward. Across the river, Soviet scouts and border guards held their nerve, counting enemy shadows and watching for a break in the line. The clash at Shachaofeng became a lightning rod: a small force crossed into Manchurian soil in the restless dark, provoking a broader crisis just as diplomacy teetered. #179 From Darkness to Crest: The Changkufeng Battle Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

As remarked in the 19th division's war journal "With sunset on the 30th, the numbers of enemy soldiers increased steadily. Many motor vehicles, and even tanks, appear to have moved up. The whole front has become tense. Hostile patrols came across the border frequently, even in front of Chiangchunfeng. Tank-supported infantry units were apparently performing offensive deployment on the high ground south of Shachaofeng." Situation maps from the evening indicated Soviet patrol activity approaching the staging area of Nakano's unit near the Tumen, moving toward Noguchi's company to the left of Chiangchunfeng, and advancing toward Matsunobe's unit southwest of Shachaofeng. Russian vessels were depicted ferrying across Khasan, directly behind Changkufeng, while tanks moved south from Shachaofeng along the western shores of the lake. The 19th division's war journal states "Then it was ascertained that these attack forces had gone into action. All of our own units quietly commenced counteraction from late that night, as scheduled, after having systematically completed preparations since nightfall." Meanwhile, to the north, the Hunchun garrison reinforced the border with a battalion and tightened security. All evidence supported the view that Suetaka "in concept" and Sato"(in tactics" played the main part in the night-attack planning and decisions. Sato was the only infantry regimental commander at the front on 30 July. One division staff officer went so far as to say that Suetaka alone exerted the major influence, that Sato merely worked out details, including the type of attack and the timing. Intertwined with the decision to attack Changkufeng was the choice of an infantry regiment. The 76th Regiment was responsible for the defense of the sector through its Border Garrison Unit; but the latter had no more than two companies to guard a 40-mile border extending almost to Hunchun, and Okido's regimental headquarters was 75 miles to the rear at Nanam. T. Sato's 73rd Regiment was also at Nanam, while Cho's 74th Regiment was stationed another 175 miles southwest at Hamhung. Thus, the regiment nearest to Changkufeng was K. Sato's 75th, 50 miles away at Hoeryong. Although Suetaka had had time to shuffle units if he desired, Sasai suggested that troop movements from Nanam could not be concealed; from Hoeryong they might be termed maneuvers. Suetaka undoubtedly had favorites in terms of units as well as chiefs. K. Sato had served longest as regimental commander, since October 1937; Okido's date of rank preceded K. Sato's, but Okido had not taken command until 1938. He and Cho were able enough, but they were unknown quantities; T. Sato and Cho were brand-new colonels. Thus, K. Sato was best known to Suetaka and was familiar with the terrain. While he did not regard his regiment as the equal of units in the Kwantung Army or in the homeland, K. Sato's training program was progressing well and his men were rugged natives of Nagano and Tochigi prefectures. From the combat soldier's standpoint, the Changkufeng Incident was waged between picked regulars on both sides. The matter of quantitative regimental strength could have played no part in Suetaka's choice. The 74th, 75th, and 76th regiments each possessed 1,500 men; the 73rd, 1,200. Even in ordinary times, every unit conducted night-attack training, attended by Suetaka, but there was nothing special in July, even after the general inspected the 75th Regiment on the 11th. It had been said that the most efficient battalions were selected for the action. Although, of course, Sato claimed that all of his battalions were good, from the outset he bore the 1st Battalion in mind for the night attack and had it reconnoiter the Changkufeng area. Some discerned no special reasons; it was probably a matter of numerical sequence, 1st-2nd-3rd Battalions. Others called the choice a happy coincidence because of the 1st Battalion's 'splendid unity' and the aggressive training conducted by Major Ichimoto, who had reluctantly departed recently for regimental headquarters. Coming from the 75th Regiment headquarters to take over the 1st Battalion was the 40-year-old aide Major Nakano. By all accounts, he was quiet, serious, and hard-working, a man of noble character, gentle and sincere. More the administrative than commander type, Nakano lacked experience in commanding battalions and never had sufficient time to get to know his new unit (or they, him) before the night assault. He could hardly be expected to have stressed anything particular in training. Since there was no battalion-level training, the most valid unit of comparison in the regiment was the company, the smallest infantry component trained and equipped to conduct combat missions independently. Sato valued combat experience among subordinates; Nakano's 1st Battalion was considered a veteran force by virtue of its old-timer company commanders. All but one had come up through the ranks; the exception, young Lieutenant Nakajima, the darling of Sato, was a military academy graduate. For assault actions synchronized with those of the 1st Battalion, Sato selected Ito, the one line captain commanding the 6th Company of the 2nd Battalion, and Takeshita, 10th Company commander, one of the two line captains of the 3rd Battalion. In short, Sato had designated five veteran captains and a promising lieutenant to conduct the night-attack operations of 30-31 July, the first Japanese experience of battle against the modern Red Army. During the last two weeks of July, numerous spurious farmers had gambled along the lower reaches of the Tumen, reconnoitered the terrain, and prepared for a crossing and assault. Scouts had operated on both the Manchurian and Korean sides of the river. Major Nakano had conducted frequent personal reconnaissance and had dispatched platoon and patrol leaders, all heavy-weapons observation teams, and even the battalion doctor to Sozan Hill, to Chiangchunfeng, and close to enemy positions. In Korean garb and often leading oxen, the scouts had threaded their way through the Changkufeng sector, sometimes holing up for the night to observe Soviet movements, soil and topography, and levels of illumination. From this data, Nakano had prepared reference materials necessary for an assault. Hirahara, then located at Kucheng BGU Headquarters, had established three observation posts on high ground to the rear. After Chiangchunfeng had been occupied, Hirahara had set up security positions and routes there. Regarding Changkufeng, he had sought to ensure that even the lowest private studied the layout. Formation commanders such as Takeshita had volunteered frequently. Sato had also utilized engineers. Since the order to leave his station on 17 July, Lieutenant Colonel Kobayashi had had his regiment engage in scouting routes, bridges, and potential fords. Sato's 1st Company commander had prepared a sketch during 3% hours of reconnaissance across from Hill 52 during the afternoon of 18 July. Captain Yamada's intelligence had contributed to the tactical decisions and to knowledge of Russian strength and preparations. The most important information had been his evaluation of attack approaches, suggesting an offensive from the western side, preferably against the right flank or frontally. This concept had been the one applied by the regiment in its night assault two weeks later; Yamada had died on the green slopes he had scanned. Cloudy Saturday, 30 July, had drawn to a close. The moment had been at hand for the 75th Regiment to storm the Russians atop Changkufeng. Setting out from Fangchuanting at 22:30, Nakano's battalion, about 350 strong, had assembled at a fork one kilometer southwest of Changkufeng. The roads had been knee-deep in mud due to intermittent rain and downpours on 29–30 July. Now the rain had subsided, but clouds had blotted out the sky after the waning moon had set at 22:30. Led by Sakata's 1st Platoon leader, the men had marched silently toward the southern foot of Changkufeng; the murk had deepened and the soldiers could see no more than ten meters ahead. It had taken Sakata's men less than an hour to push forward the last 1,000 meters to the jump-off point, where they had waited another two hours before X-hour arrived. Scouts had advanced toward the first row of wire, 200–300 meters away. Platoon Leader Amagasa had infiltrated the positions alone and had reconnoitered the southeastern side of the heights. Sakata had heard from the patrols about the entanglements and their distance and makeup. While awaiting paths to be cut by engineer teams, the infantry had moved up as far as possible, 150 meters from the enemy, by 23:30. Although records described Changkufeng as quite steep, it had not been hard to climb until the main Russian positions were reached, even though there were cliffs. But as the craggy peak had been neared, the enemy defenses, which had taken advantage of rocks and dips, could not have been rushed in a bound. It had been 500 meters to the crest from the gently sloping base. The incline near the top had been steep at about 40 degrees and studded with boulders. Farther down were more soil and gravel. Grass had carpeted the foot. Japanese Army radio communications had been in their infancy; wire as well as runners had served as the main means of linking regimental headquarters with the front-line infantry, crossing-point engineers, and supporting guns across the Tumen in Korea. From Chiangchunfeng to the 1st Battalion, lines had been installed from the morning of 29 July. Combat communications had been operated by the small regimental signal unit, 27 officers and men. In general, signal traffic had been smooth and reception was good. Engineer support had been rendered by one platoon, primarily to assist with wire-cutting operations. Nakano had ordered his 1st Company to complete clearing the wire by 02:00. At 23:30 the cutters had begun their work on the right with three teams under 1st Lieutenant Inagaki. Since the proposed breach had been far from the enemy positions and there were no outposts nearby, Inagaki had pressed the work of forced clearing. The first entanglements had been breached fairly quickly, then the second. At about midnight, a dim light had etched the darkness, signaling success. There had been two gaps on the right. On the left side, Sakata's company had hoped to pierce the barbed wire in secrecy rather than by forced clearing. Only one broad belt of entanglements, actually the first and third lines, had been reconnoitered along the south and southeastern slopes. Sakata had assigned one team of infantry, with a covering squad led by Master Sergeant Amagasa, to the engineer unit under 2nd Lieutenant Nagayama. Covert clearing of a pair of gaps had begun. The Russian stakes had been a meter apart and the teams cut at the center of each section, making breaches wide enough for a soldier to wriggle through. To the rear, the infantry had crouched expectantly, while from the direction of Khasan the rumble of Soviet armor could be heard. At 00:10, when the first line of wire had been penetrated and the cutters were moving forward, the silence had been broken by the furious barking of Russian sentry dogs, and pale blue flares had burst over the slopes. As recalled by an engineer "It had been as bright as day. If only fog would cover us or it would start to rain!" At the unanticipated second line, the advancing clearing elements had drawn gunfire and grenades. But the Russians had been taken by surprise, Sakata said, and their machine guns had been firing high. Two engineers had been wounded; the security patrol on the left flank may have drawn the fire. Sakata had crawled up to Lieutenant Nagayama's cutting teams. One party had been hiding behind a rock, with a man sticking out his hand, grasping for the stake and feeling for electrified wire. Another soldier lay nearby, ready to snip the wire. The enemy had seemed to have discerned the Japanese, for the lieutenant could hear low voices. Although the cutters had been told to continue clearing in secrecy, they had by now encountered a line of low barbed wire and the work had not progressed as expected. Forced clearing had begun, which meant that the men had to stand or kneel, ignoring hostile fire and devoting primary consideration to speed. The infantrymen, unable to delay, had crawled through the wire as soon as the cutters tore a gap. Ten meters behind the small breaches, as well as in front of the Soviet positions, the Japanese had been troubled by fine low strands. They had resembled piano-wire traps, a foot or so off the ground. The wires had been invisible in the grass at night. As one soldier recalled "You couldn't disengage easily. When you tried to get out, you'd be sniped at. The wires themselves could cut a bit, too." Sakata had kept up with the clearing teams and urged them on. On his own initiative, Amagasa had his men break the first and third lines of wire by 01:50. Meanwhile, at 01:20, Nakano had phoned Sato, reporting that his forces had broken through the lines with little resistance, and had recommended that the attack be launched earlier than 2:00. Perhaps the premature alerting of the Russians had entered into Nakano's considerations. Sato had explained matters carefully, that is, rejected the suggestion, saying Changkufeng must not be taken too early, lest the enemy at Shachaofeng be alerted. The entire battalion, redeployed, had been massed for the charge up the slope. In an interval of good visibility, the troops could see as far as 40 meters ahead. A little before 02:00, Nakano had sent runners to deliver the order to advance. When the final obstructions had been cut, Nagayama had flashed a light. Then a white f…

    Show notes

    Last time we spoke about the beginning of a conflict between the USSR and Japan. In the frost-hardened dawns by the Chaun and Tumen, two powers eye a ridge called Changkufeng, each seeing a prize and fearing a trap. On the Soviet side, weary front-line troops tighten their grip, while Moscow's diplomats coaxed restraint through Seoul and Harbin. As July unfolds, Tokyo's generals push a dangerous idea: seize the hill with a surprise strike, then bargain for peace. Seoul's 19th Division is readied in secret, trains loaded with men and horses, movement masked, prayers whispered to avoid widening the rift. Japanese scouts in white Hanbok disguise, peering at trenches, wire, and watchful Russians. Russian border guards appear as shadows, counters slipping into place, yet both sides hold their fire. On July 29, a skirmish erupts: a platoon crosses a shallow line, clashes flare, and bodies and banners ripple in the cold air. #178 Night Attacks and Diplomatic Strains: The Lake Khasan Conflict Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. A second troop train was scheduled to depart Agochi for Nanam on the night of 29 July, carrying back the initial elements of the 75th Infantry. At Haigan, regimental commander Sato was pulling on his boots at 16:00 when the division informed him that fighting had broken out near Shachaofeng since 15:00 and that the Russians were assembling forces in that area. Suetaka ordered Sato's 3rd Battalion, which had not been slated to leave until the following night, to proceed to Kucheng; the remainder of the regiment was to assemble at Agochi. After consulting with Division Staff Officer Saito at Agochi, Sato returned to Haigan with the conclusion that "overall developments did not warrant optimism, it was imperative to prepare to move the entire regiment to the battlefield." One of Sato's first actions was to telephone a recommendation to the division that he be allowed to occupy Hill 52, which commanded the approaches to Changkufeng from south of Khasan. Suetaka approved, and at 17:30, Yamada's company was ordered to proceed to Shikai along with Hirahara's battalion. Meanwhile, Suzuki's 15th Heavy Field Artillery Regiment, which had been among the last units ordered to leave, had finished loading at Agochi by about 15:00. Sato recommended to Suetaka that a portion of Suzuki's regiment be attached to him; this was why Suetaka decided to transfer one of the two batteries to the 75th Infantry. The rest of the heavy artillery concentrated at Kyonghun. Suetaka's orders, issued at 18:20, called for Sato to have two of his battalions, the 1st and 3rd, cross the Tumen as soon as possible, with engineer support. Attached was Narukawa's heavy battery. Sato's mission was twofold: to assist Senda and to watch the enemy in the Changkufeng area. Sato arrived at 21:15 in Shikai. There, he assembled a number of his officers, including Yamada, and explained his plan: the 1st Company plus machine guns were to cross the Tumen from Sozan ahead of the other units, occupy Hill 52 with an element, and concentrate the main body at the foot of Fangchuanting to await Hirahara's battalion. A portion of the 19th Engineers would go to Sozan to assist the 1st Company with its river crossing. Amid heavy rain and darkness, the various units set out at 22:15. The platoon sent to Hill 52 arrived before dawn on the 30th, the rest of the forces somewhat later, though Sato had intended to move everybody across the river by the early hours. On the 29th the engineer regiment commander, Kobayashi, had also arrived at Shikai. He ordered Captain Tomura to handle the crossing in the vicinity of Sozan, as well as preparations for a future offensive with the main body. When Kobayashi reached Kucheng, he learned from Hirahara not only about the front-line situation but also about Sato's important plans: "The K. Sato force is going to cross the river tonight, 29–30 July. A night attack will be launched against Changkufeng on the night of 30–31 July." Kobayashi issued orders to his two commanders to assist the crossing by Nakano's infantry unit, 1st Battalion, 75th Regiment at Matsu'otsuho and Sozan, and, in addition, to cooperate with the position attack by Nakano and help in the assault at Hill 52. Most of these young officers, such as Seutaka dishing out orders were performing what the Japanese termed "dokudan senko" or "arbitrary or independent action". Japanese operational regulations actually contained a section dealing with dokudan senko, by which initiative, not imperiousness, was meant. Two elements were involved: control but encouragement of self-reliant thinking. This subject became important in training officers, all of whom, including such infantry experts as Suetaka, were well acquainted with the requirements. Combat missions were stipulated in operations orders, but, if these were not realistic, initiative was to come into play, though only when there was no time to contact superiors. By the same token, commanders had to be ready to assume full responsibility if matters turned out adversely. "We were disciples of the 'Moltke' system of AGS control, with dual authority vis-à-vis the local forces and the chief of staff." The Korea Army's version of events on 29 July, there was no mention of any report received from the division prior to 17:30. Details did not reach Seoul, in the form of printed divisional intelligence reports and operational orders, until 1 August. The late afternoon report from Kyonghun provided the Korea Army authorities with little solid information, but Seoul had to notify higher headquarters immediately. Kitano sent messages to Tokyo and Hsinking at 19:15. The command and Kwantung Army were told that, in addition to Senda's assault party, 40 Japanese soldiers were deployed west of Changkufeng and at Yangkuanping. The division's main forces had begun the rail pullback from the 28th, leaving behind only two infantry battalions and a mountain artillery battalion for the time being. At 21:20 on 29 July, Korea Army Headquarters received the text of Suetaka's full report, which concluded: "With a view toward a possible emergency, the division suspended movement back of the 75th Regiment and is making necessary arrangements to have them advance instead. The latest affair derives sheerly from the enemy's unlawful challenge. It is my firm belief that the nature of this incident differs completely from the one at Changkufeng and should be handled separately. At present, since communication with the forward lines is not good, Lieutenant Colonel Senda (who is at the front) has been entrusted with command, but I assume entire responsibility for the consequences." Instead of boarding their trains at Agochi, Sato's regiment and supporting engineers moved to the Manchurian side of the Tumen as soon as possible. Suetaka called Sato's 2nd Battalion to Kyonghun as divisional reserve. Subsequent dispatches claimed that: (1) Senda's unit, which had driven off intruders in the Shachaofeng area once, was engaged against new Soviet forces (sent at 18:20, 29th); (2) Senda's unit had expelled trespassers, and a combat situation had developed near Shachaofeng (22:00, 29th); (3) fighting was going on in the vicinity of Shachaofeng (06:40, 30th). Korea Army Headquarters, however, obtained no more important communication concerning the events of 29 July than a report, sent that evening by Suetaka, that revealed his concern about a possible Soviet attack in the Wuchiatzu sector near the neck of the long Changkufeng appendix. After the clash at Shachaofeng, a general officer, Morimoto, happened to be visiting Colonels Okido and Tanaka in Nanam. Both of them were said to be of the pronounced opinion that no troubles ought to be provoked with the USSR while the critical Hankow operation lay ahead; yet Suetaka apparently had some intention of striking at the Soviet intruders, using the 75th Regiment. They urged that this policy not be adopted and that Suetaka be approached directly; the channel through Y. Nakamura, the division chief of staff, was hopeless. Although in agreement, General Morimoto declined to approach Suetaka; since the latter seemed to have made up his mind, it would be inappropriate to "meddle" with his command. Suetaka was functioning as an operations chief at that time. Apart from the mobilization staff officer, who was not enthusiastic about aggressive action, the only other officer who may have affected the decisionmaking process was the Hunchun OSS chief, Maj. Tanaka Tetsujiro, a positive type who shared Suetaka's views and was probably with him on the 29th as well as 30th. Although developments at Suetaka's command post were known more as the result of silence than of elucidation, we possessed considerable information about thinking at the Korea Army level: "Suetaka contacted us only after his men had driven out the enemy near Shachaofeng. Till then, the front had been relatively quiet and we were of the opinion all or most of the deployed forces were on their way home. We at Seoul had no foreknowledge of or connection with the 29 July affair. Reports came in; we never sent specific orders. Triggered by the affray at Shachaofeng, the division attacked on its own initiative. It was our understanding that very small Japanese forces had been committed to evict a dozen enemy scouts and that, when a platoon of ours got atop the hill, they observed surprisingly huge hostile concentrations to the rear. This was probably why the platoon pulied back, although much has been made of the desire to obey the nonaggravation policy to the letter. We at Seoul felt that this was a troublesome matter—that our side had done something unnecessary. When the division finally made its report, the army had to reach some decision. There were two irreconcilable ways of looking at things. We might condemn what had been done, and the division ought to be ordered to pull out promptly, having arbitrarily and intolerably acted against the known facts that Imperial sanction for use of force had been withheld and Tokyo had directed evacuation of the moved-up units. The opposing, eventually predominant view was that the division commander's course of action ought to be approved. Perusal of small-scale maps of the locale indicated a clear violation of the frontier, something not proved in the case of Changkufeng. We shared the division commander's interpretation. His BGU had its mission, and he was acting with foresight to solve matters positively and on his own, since he was the man closest to the problem. General Nakamura felt that the latest development was inevitable; our units did not cross the Tumen until the Soviets attacked us in force. Therefore, the division's actions were approved and a report was rendered promptly to Tokyo. It could be said that our outlook served to "cover" the division commander, in a way. But if IGHQ had ordered us to desist, we would have". Nakamura added: "I was of the opinion the only solution was to drive the Soviet troops outside Manchukuoan territory; therefore, I approved the action by the division." Such sanction had been granted on the basis of information supplied to Seoul by Suetaka on the evening of 29 July, again post facto. At 01:20 on the 30th, Nakamura wired Suetaka a message characterized by gracious phrasing that suggested his grave concern: "One ought to be satisfied with expelling from Manchurian territory the enemy attacking our unit on the . . . heights southwest of Shachaofeng. It is necessary to keep watch on the enemy for the time being, after having pulled back to the heights mentioned above, but we desire that matters be handled carefully to avoid enlargement; in case the foe has already pulled back south of Shachaofeng . . . he need not be attacked." Nakamura also sent a wire to the AGS chief, the War Minister, and the Kwantung Army commander. After conveying the information received from Suetaka, Nakamura continued: "In spite of the fact that our troops have been patient and cautious . . . this latest incident [near Shachaofeng] started with Soviet forces' arrogant border trespassing and . . . unlawful challenge. Therefore, I am convinced that this affair must be dealt with separately from the incident at Changkufeng. Nevertheless, I shall endeavor to handle matters so that the incident will not spread and shall make it my fundamental principle to be satisfied with evicting from Manchurian territory the hostile forces confronting us. The Korea Army chief of staff is being dispatched quickly to handle the incident". The Korea Army, "painfully slow to act," says a Kwantung Army major, was merely the intermediary link, the executor of Tokyo's desires. In the case of remote Shachaofeng, there was an inevitable gap between on-the-spot occurrences and AGS reactions. By then, Arisue, Kotani, and Arao, Inada's observers, had returned to Japan—an important fact, given the "Moltke" system of staff control. Nevertheless, their return must have exerted significant effects on central operational thinking. Kotani remembered that his AGS subsection had given him a welcome-home party on the night of 29 July when an emergency phone call was received from the duty officer. "It was about the clash at Shachaofeng. The festivities came to an abrupt end and I headed for the office. From then till the cease-fire on 11 August, I remained at the AGS night and day." Since the 19th Division had furnished higher headquarters with minimal information, Tokyo, like Seoul, had only a few ostensible facts to act upon. But this had been the first combat test for the Korea Army, which needed all the encouragement and assistance possible. Although Japanese field armies, notably the Kwantung Army, were notorious for insubordination, one could not overemphasize the fact that the Korea Army was meek and tractable. If Nakamura had concluded that Suetaka acted properly (which reports from Seoul indicated), the AGS could hardly demur. It would have been unrealistic to think that Tokyo, although cautious, was "softer" about the Russian problem than front-line forces. There had been no concern over time lags; details were Seoul's province. Reaction took time at every level of the chain of command. Decision making in the Japanese Army had been a many-layered process. The Army general staff had been of the opinion that initial guidance ought to have been provided to the Korea Army soon, particularly since there had been evidence of failure to convey intentions promptly to the front and no high command staff officer remained to direct matters. After hearing from Seoul twice about the Shachaofeng affair, the responsible Army general staff officers conferred at length. Stress had been laid on the indivisibility of the Shachaofeng and Changkufeng incidents. It had also been evident that further information was required. On that basis, a "handling policy for the Shachaof…

    3.177 Fall and Rise of China: Point of no return for the USSR and Japan Nov 25, 2025
    Show notes

    Last time we spoke about the Changkufeng Incident. In a frost-bitten dawn along the Chaun and Tumen rivers, a border notched with memory becomes the stage for a quiet duel of will. On one side, Japanese officers led by Inada Masazum study maps, mud, and the hill known as Changkufeng, weighing ground it offers and the risk of war. They glimpse a prize, high ground that could shield lines to Korea—yet they sense peril in every ridge, every scent of winter wind. Across the line, Soviet forces tighten their grip on the crest, their eyes fixed on the same hill, their tents and vehicles creeping closer to the border. The air hums with cautious diplomacy: Moscow's orders pulse through Seoul and Harbin, urging restraint, probing, deterring, but never inviting full-scale conflict. Yet every patrol, every reconnaissance, seems to tilt the balance toward escalation. #177 The point of no return for the USSR and Japan Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. Days passed and the local emissaries had not been released by the Russians. Domei reported from Seoul that the authorities were growing worried; the "brazen" actions of Soviet front-line forces infuriated the Manchurians and Japanese. From Seoul, too, came ominous news that villagers were preparing to evacuate because they feared fighting would soon begin in the Changkufeng area. While diplomatic activity continued in Moscow without effect, the Tokyo press continued to report intense military activity throughout the Soviet Far East—the greatest massing of troops in months, with planes, armored cars, and motorized equipment choking the Trans-Siberian railway. The press was dominated by commentary about the danger of war. One enterprising Tokyo publisher ran advertisements under the heading: "The Manchukuo-Soviet Border Situation Is Urgent—Ours Is the Only Detailed Map of the Soviet Far East: Newspaper-size, in seven clear colors, offset printed, only 50 sen." Although the Manchukuoan foreign office issued a statement on 20 July about the dire consequences the Soviets were inviting, it is probable that the next Russian actions, of a conciliatory nature, were reached independently. Either Moscow had taken almost a week to make the decision, or the diplomatic conversations there had had an effect. Local Japanese authorities reported inactivity on the Changkufeng front from the morning of 23 July. On the next day, word was received that the USSR proposed to return the two emissaries as "trespassers." At midday on 26 July, the Russians released the blindfolded agents at a border site along the Novokievsk road. After completing the formalities, the Japanese asked the Russians for a reply concerning local settlement of the incident. According to Japanese sources, the "flustered" Colonel Grebennik answered: "My assignment today was merely to turn over the envoys. As for any request about the Changkufeng Incident, our guard commander must have asked for instructions from the central government. I think this is the type of matter which must be answered by the authorities at Moscow through diplomatic channels." Grebennik's postwar recollection does not differ appreciably from the Japanese version. Soviet sources mention a second effort by the Japanese military to deliver a message under more forceful circumstances. On 23 July a Soviet border unit drove off a four-man party. Russian cavalry, sent to investigate, discovered that the Japanese had pulled down a telegraph pole, severed lines 100–150 meters inside Soviet territory, absconded with wire, and left behind a white flag and a letter. Undated, unsigned, and written in Korean, the message struck Grebennik as being substantively the same as the communication delivered formally by the emissaries on 18 July. Japanese materials make no reference to a second, informal effort by local forces, but there is little reason to doubt that such an attempt, perhaps unauthorized, was made. Although Japanese efforts at low-level negotiations came to naught, two observations emerged from the local authorities and the press. First, on-the-spot negotiations had broken down; it had been difficult even to reclaim the emissaries, and the Russians in the Posyet region were using various pretexts to refer matters to diplomatic echelons. Second, the Russians had released the men. Some interpreted this as the first evidence of Soviet sincerity; possibly, the USSR would even return Matsushima's body as a step toward settlement. Other Japanese observers on the scene warned the public that it was imperative to stay on guard: "All depends on how diplomacy proceeds and how the front-line troops behave." Yet the excitement in the Japanese press began to abate. It is difficult to ascertain the nature of the decision-making process on the Russian side after the Japanese attempted local negotiations. The Soviets contend that nothing special had been undertaken before the Japanese provoked matters at the end of July. Grebennik, however, admits that after receiving the two Japanese communications, "we started to prepare against an attack on us in the Lake Khasan area." He and a group of officers went to Changkufeng Hill and sent as many border guards there as possible. Although he personally observed Japanese troops and instructed his officers to do the same, he denied categorically that the Russians constructed trenches and fortifications. Only the observation of Manchurian territory was intensified while instructions were awaited from higher headquarters. For its part, the Korea Army was carrying out Imperial general headquarters first instructions while pursuing a wait-and-see policy. On 16 July, Korea Army Headquarters wired an important operations order to Suetaka. With a view toward a possible attack against intruders in the Khasan area, the army planned to make preparations. The division commander was to alert stipulated units for emergency dispatch and send key personnel to the Kyonghun sector to undertake preparations for an attack. Lt. Col. Senda Sadasue, BGU commander of the 76th Infantry Regiment, was to reconnoiter, reinforce nearby districts, and be ready for emergencies. Particular care was enjoined not to irritate the Soviet side. Maj. Gen. Yokoyama Shinpei, the Hunchun garrison commander, was to maintain close contact with the BGU and take every precaution in guarding the frontiers. Like Senda, Yokoyama was warned against irritating the Russians. Korea Army Headquarters also dispatched staff to the front and had them begin preparations, envisaging an offensive. Upon receipt of the army order, Suetaka issued implementing instructions from his Nanam headquarters at 4:30 A.M. on the 17th. The following units were to prepare for immediate alert: the 38th Infantry Brigade Headquarters, 75th Infantry Regiment, 27th Cavalry Regiment, 5th Antiaircraft Regiment, and 19th Engineer Regiment. The same instructions applied to the next units, except that elements organic to the division were designated: the 76th Infantry Regiment, 25th Mountain Artillery Regiment, and 15th Heavy Field Artillery Regiment. Another order enjoined utmost care not to irritate the Russians; Japanese actions were to be masked. Next came a directive to the forces of Senda and K. Sato. The former comprised mainly the 76th Infantry BGU and a cavalry platoon. The latter was built around the 75th Infantry Regiment, the Kucheng garrison unit, another cavalry platoon, two mountain artillery and one heavy field artillery battalion, and the 19th Engineers. Suetaka's idea about a solution to the border troubles had become concrete and aggressive. From the night of July 17, concentration would be accomplished gradually. The exact timing of the attack would be determined by subsequent orders; in Senda's area, there was no such restriction regarding "counteraction brought on by enemy attack." Division signal and intendant officers would conduct reconnaissance related to communications, billeting, food, and supplies. Sato and his subordinates were to reconnoiter personally. Having ordered the division to begin concentration and to stand by, Korea Army Headquarters was prepared the next morning, July 17, to direct the movement. Nevertheless, there was concern in Seoul that Suetaka's advance elements might cross the Tumen River into Manchurian territory, which could result in a clash with Soviet troops. Such an outcome might run counter to the principle established by Imperial general headquarters. Consequently, it was decided that "movement east of the river would therefore have to be forbidden in the Korea Army's implementing order." Nakamura transmitted his operational instructions to Suetaka at 6:00 on July 17: "No great change in latest situation around Lake Khasan. Soviet forces are still occupying Changkufeng area. Diplomaticlevel negotiations on part of central authorities and Manchukuoan government do not appear to have progressed. Considering various circumstances and with view to preparations, this army will concentrate elements of 19th Division between Shikai, Kyonghun, Agochi." Restrictions stipulated that the division commander would transport the units by rail and motor vehicle and concentrate them in the waiting zone in secret. Movement was to begin on the night of July 17 and to be completed the next day. Further orders, however, must govern unit advance east of the Tumen as well as use of force. The remainder of the division was to stay ready to move out. Troops were to carry rations for about two weeks. Late that day, Suetaka received an order by phone for his subordinates in line with Seoul's instructions. Senda would handle the concentration of elements assembling at Kyonghun, and Sato would do the same for the main units arriving at Agochi. A communications net was to be set up quickly. Caution was to be exercised not to undertake provocative actions against the opposite bank of the Tumen, even for reconnaissance. The division would dispatch two trains from Hoeryong and four from Nanam. At 11:58 pm on 18 July, the first train left Hoeryong for Agochi. Concentration of units was completed by dawn. By that time, the Japanese had dispatched to the border 3,236 men and 743 horses. Past midnight on 20 July, Division Chief of Staff Nakamura wired headquarters that the division was ready to take any action required, having completed the alert process by 11 pm. Japanese scouting of the Changkufeng sector began in earnest after mid-July. Although the affair had seemed amenable to settlement, Sato took steps for an emergency from around the 14th. His thoughts centered on readiness for an attack against Changkufeng, which simultaneously required reconnaissance for the assault and preparation to pull the regiment back quickly to Hoeryong if a withdrawal was ordered. After arriving at Haigan on 18 July, Sato set out with several engineers. At Kucheng, the officers donned white Korean clothing, presumably the disguise directed by the division—and boarded native oxcarts for a leisurely journey southward along the Korean bank of the Tumen across from Changkufeng. The seemingly innocent "farmers" studied the river for crossing sites and Changkufeng Hill for the extent of enemy activity. On the hill's western slope, in Manchurian territory, three rows of Russian entanglements could be observed 300 feet below the crest. Only a handful of soldiers were visible, probably a platoon, certainly not more than a company. Infantry Captain Yamada Teizo conducted secret reconnaissance of the entire Changkufeng-Hill 52 sector for 314 hours in the afternoon of 18 July. Even after intense scanning through powerful binoculars, he could detect no more than 19 lookouts and six horsemen; camouflage work had been completed that day, and there were ten separate covered trench or base points. Barbed wire, under camouflage, extended about four meters in depth, yet even Yamada's trained eye could not determine whether there was one line of stakes or two. He jotted down what he could see and compared his information with that learned from local police. Artillery Colonel R. Tanaka shared the view that the Soviets had intruded. When he went reconnoitering along the Korean bank, he observed Russian soldiers entrenched around the hilltop, easily visible through binoculars at a range of two kilometers. Trenches had been dug 20 to 30 meters below the crest on the western slope. Eventually, there were three rows of barbed wire, the first just below the trenches and the lowest 100 meters under the summit. Tanaka estimated Soviet strength at two companies (about 200 men). Suetaka's intelligence officer, Sasai, recalls seeing barbed wire after Japanese units deployed to the front on 18–19 July; he had surmised then that the entanglements were being prepared out of fear of a Japanese assault. To obtain first-hand information, the Gaimusho ordered a section chief, Miura Kazu'ichi, to the spot. Between 23 July and the cease-fire in August, Miura collected data at Kyonghun and transmitted reports from the consulate at Hunchun. On 28 July he visited Sozan on the Korean bank. He observed Soviet soldiers on the western slopes of Changkufeng, digging trenches and driving stakes. These actions were clearly on Manchukuoan territory even according to Soviet maps. Miura insisted that he saw no friendly troops on territory claimed by the Russians and observed no provocative actions by the Japanese. These statements are supported by a map drawn for him in early August by Division Staff Officer Saito Toshio, a sketch Miura retained as late as 1947. Miura's testimony is tempered by his assertion that he saw a red flag flying near the top of Changkufeng Hill. This contention conflicts with all evidence, as Russian lawyers at the International Military Tribunal for the Far East argued, it is improbable that a Soviet frontier post, highly interested in camouflage, would have hoisted a pennon so large that it could be seen from Sozan. Russian sources are unanimous in stating that no flag was put up until 6 August and that no trenches or entanglements were established by Soviet border guards in July, at least prior to the 29th. The two Army General staff consultants, Arisue and Kotani, arrived in Seoul on 16 July, the day Korea Army Headquarters was ordering an alert for the 19th Division "with a view toward a possible attack against enemy intruders." Inada dispatched them mainly to inspect the frontline situation; but he had not fully decided on reconnaissance in force. At Shikai, Arisue and Kotani donned Korean garb and traveled by oxcart on the Korean side of the Tumen, reconnoitering opposite the Shachaofeng sector. Kotani was convinced that hostile possession of Changkufeng posed a serious threat to the Korean railway. He agreed with the division's estimate that, if the Japanese did decide to seize Changkufeng, it ought not to be too difficult. Arisue, as senior observer, dispatched messages from Kyonghun to Tokyo detailing their analysis and recommendations. Meanwhile, in Tokyo, on 17 July the central military authorities r…

    3.176 Fall and Rise of China: Changkufeng Incident Nov 17, 2025
    Show notes

    Last time we spoke about the Soviet-Japanese Border Conflict. The border between Soviet Manchuria and Japanese-occupied territories emerges not as a single line but as a mosaic of contested spaces, marks, and memories. A sequence of incidents, skirmishes along the Chaun and Tumen rivers, reconnaissance sorties, and the complex diplomacy of Moscow, Tokyo, and peripheral actors to trace how risk escalated from routine patrols to calibrated leverage. On the ground, terrain functioned as both obstacle and argument: ridges like Changkufeng Hill shaping sightlines, river valleys shaping decisions, and markers weathered by snow, wind, and drift. In command tents, officers translated terrain into doctrine: contingency plans, supply routes, and the precarious calculus of restraint versus escalation. Both nations sought to establish firmer defensive barriers against the other. Inevitably they were destined to clash, but how large that clash would become, nobody knew. #176 The Changkufeng Incident Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. In the last episode we broke down a general history of the Soviet-Japanese Border Conflict and how it escalated significantly by 1938. Colonel Inada Masazum serving as chief of the 2nd Operations Section within the Operations Bureau in March of 1938 would play a significant role in this story. When the Japanese command's attention was drawn to the area of Changkufeng, consideration was given to the ownership and importance of the disputed high ground. Inada and his operations section turned to an appraisal of the geography. The officers had been impressed by the strategic importance of the Tumen, which served to cut off the hill country from North Korea. In the Changkufeng area, the river was a muddy 600 to 800 meters wide and three to five meters deep. Japanese engineers had described rowing across the stream as "rather difficult." Russian roads on the left bank were very good, according to Japanese intelligence. Heavy vehicles moved easily; the Maanshan section comprised the Russians' main line of communications in the rear. To haul up troops and materiel, the Russians were obliged to use trucks and ships, for there were no railways apart from a four-kilometer line between the harbor and town of Novokievsk. Near Changkufeng, hardly any roadways were suitable for vehicular traffic. On the right, or Korean, bank of the Tumen, there were only three roads suitable for vehicular traffic, but even these routes became impassable after a day or two of rain. In the sector between Hill 52 to the south and Shachaofeng to the north, the most pronounced eminences were Chiangchunfeng and the humps of Changkufeng. Rocky peaks were characteristically shaped like inverted T's, which meant many dead angles against the crests. The gentle slopes would allow tanks to move but would restrict their speed, as would the ponds and marshes. In general, the terrain was treeless and afforded little cover against aircraft. Against ground observation or fire, corn fields and tall miscanthus grass could provide some shielding. Between Chiangchunfeng and the Tumen, which would have to serve as the main route of Japanese supply, the terrain was particularly sandy and hilly. This rendered foot movement difficult but would reduce the effectiveness of enemy bombs and shells. The high ground east of Khasan afforded bases for fire support directed against the Changkufeng region. Plains characterized the rest of the area on the Soviet side, but occasional streams and swamps could interfere with movement of tanks and trucks. The only towns or villages were Novokievsk, Posyet, Yangomudy, and Khansi. At Kozando there were a dozen houses; at Paksikori, a few. The right bank was farmed mainly by Koreans, whose scattered cottages might have some value for billeting but offered none for cover. On the left bank, the largest hamlets were Fangchuanting, with a population of 480 dwelling in 73 huts, and Yangkuanping, where there were 39 cottages. Shachaofeng was uninhabited. Japanese occupation of Changkufeng would enable observation of the plain stretching east from Posyet Bay, although intelligence made no mention of Soviet naval bases, submarine pens, or airstrips in the immediate area of Posyet, either in existence or being built in 1938. As Inada knew, the Japanese Navy judged that Posyet Bay might have another use, as a site for Japanese landing operations in the event of war. In Russian hands, the high ground would endanger the Korean railway. This line, which started from Najin in northeastern Korea, linked up with the vital system in Manchuria at the town of Tumen and provided a short cut, if not a lifeline, between Japan and the Kwantung Army and Manchuria from across the Sea of Japan. Even from relatively low Changkufeng, six or seven miles of track were exposed to Soviet observation between Hongui and Shikai stations. The port of Najin, with its fortress zone, lay 11 miles southwest; Unggi lay even nearer. It was not the danger of Japanese shelling of Vladivostok, at an incredible range of 80 miles that was at stake but the more realistic hypothesis of Russian shelling of the rail line, and Russian screening of the Soviet side of the border. Hills and questions were thought to have two sides. It was the consensus of Japanese that Changkufeng Hill's potential value to the Russians far outweighed its possible benefits to them, or at least that the Japanese had more to lose if the Russians took the high ground by the Tumen. Inada nurtured few illusions concerning the intrinsic value of the heights. Despite the fact that the high command always had good reasons for quiescence in the north, Inada believed that the latest border difficulty could not be overlooked. By mid-July 1938 Inada's thoughts crystallized. The Japanese would conduct a limited reconnaissance in force known as iryoku teisatsu in the strategic sense. Whereas, at the tactical schoolbook level, this might mean the dispatch of small forces into enemy territory to seek local combat intelligence, at the Imperial General Headquarters level the concept was far more sweeping. There would also be useful evidence of mobilization and other buildup procedures. The affair at Changkufeng was merely a welcome coincidence, something started by the Russians but liable to Japanese exploration. Inada had no intention of seizing territory, of becoming involved in a war of attrition at a remote and minor spot, or of provoking hostilities against the USSR. The Russians would comprehend the nature of the problem, too. If they were interested in interfering seriously with the Japanese, there were numberless better locations to cause trouble along the Manchurian front; those were the places to watch. The cramped Changkufeng sector, described as "narrow like a cat's brow," could too readily be pinched off from Hunchun to render it of strategic value to either side. The bog land to the north interfered with the use of armored forces, while artillery sited on the heights along the Tumen in Korea could as easily control the area as batteries emplaced east of the lake. It was Inada's professional opinion that the Russians could commit three or four infantry divisions there at most, with no mechanized corps—no heavy tanks, in particular. No decisive battle could be waged, although, once the Russians became involved, they might have to cling to the hill out of a sense of honor. The military action would be meaningless even if the Japanese let the Russians have the heights. For their part, the Japanese would ostensibly be fighting to secure the boundary and to hold Changkufeng peak, beyond which they would not move a step onto Soviet soil. There would be no pursuit operations. Troop commitment would be limited to about one division without tank support. Japanese Air Force intervention would be forbidden. Matters would be directed entirely by Imperial General Headquarters working through the Korea Army chain of command and carried out by the local forces. Calm, clear, and dispassionate overall estimates and instructions would be based on materials available only in Tokyo. The command would not allow the Kwantung Army to touch the affair. Inada foresaw that the Japanese government might also seek a settlement through diplomacy. Although border demarcation was desirable and should be sought, the command would not insist on it, nor would it demand permanent occupation of Changkufeng summit. As soon as reconnaissance objectives had been achieved, the local forces would be withdrawn. As Inada described it "In the process, we would have taught the Russians some respect and given them a lesson concerning their repeated, high-handed provocations and intrusions. If a show of force sufficed to facilitate the negotiations and cause the Russians to back down, so much the better; the affair would be over and my point proved." The instrument for carrying out Inada's strategic design appeared to be ideal, the 19th Division, strenuously trained and high-spirited. It could be expected to perform very well if unleashed within defined limits. Colonel Suetaka was just the commander to direct local operations. Since he had been pleading to fight in China, an operation at Changkufeng might prove to be an excellent "safety valve." His staff was full of experienced, fierce warriors eager for battle. Until recently, the Korea Army commanding general had wisely kept the aggressive division away from Changkufeng Hill, but now Imperial general headquarters had its own overriding ideas and needs. How could the Japanese ensure that any military action would remain limited if the Russians chose to respond with vigor? Naturally, one infantry division, without armor or air support, could not withstand all of the Soviet forces in the maritime province. Inada answered that the mission to be assigned the 19th Division was merely the recapture of Changkufeng crest. If the Japanese side had to break off the operation, evacuation would be effected voluntarily and resolutely on Imperial general headquarters responsibility, without considerations of "face." At worst, the Japanese might lose one division, but the affair would be terminated at the Tumen River without fail. "Even so, we ought to be able to prove our theory as well as demonstrate our true strength to the Russians." In case the Soviets opted for more than limited war, the Japanese were still not so overextended in China that they could not alter their strategic disposition of troops. Although the Kwantung Army's six divisions were outnumbered four to one and the Japanese were not desirous of a war at that moment, the first-class forces in Manchuria could make an excellent showing. In addition, the high command possessed armor, heavy artillery, fighters, and bombers, held in check in Manchuria and Korea, as well as reserves in the homeland. There was also the 104th Division, under tight Imperial general headquarters control, in strategic reserve in southern Manchuria. Inada recalled "How would the Russians react? That was the answer I sought. Victory in China depended on it." By mid-July, the high command, at Inada's urging, had worked out a plan titled, "Imperial General headqaurters Essentials for Dealing with the Changkufeng Incident." Tada's telegram of 14 July to Koiso described succinctly the just-decided policy: the central authorities concurred with the Korea Army's opinion regarding the Changkufeng affair, then in embryo. Considering that Changkufeng Hill posed a direct threat to the frontier of Korea, Imperial General headqaurters would immediately urge the foreign ministry to lodge a stern protest. Next day, Tojo sent a telegram stating the Japanese policy of employing diplomacy; whether the Russians should be evicted by force required cautious deliberation in case the USSR did not withdraw voluntarily. On the basis of the guidance received from Imperial General headqaurters, the Korea Army drew up its own plan, "Essentials for Local Direction of the Changkufeng Incident," on 15 July. Intelligence officer Tsuchiya Sakae was sent promptly to the front from Seoul. At the same time, military authorities allowed the press to release news that Soviet troops were constructing positions inside Manchurian territory in an "obvious provocation." The government of Manchukuo was demanding an immediate withdrawal. Even then, those Japanese most closely connected with the handling of the Changkufeng Incident were not in agreement that everybody at command level was as ardent a proponent of reconnaissance in force as Inada claimed to be. Some thought that most, if not all, of his subordinates, youthful and vigorous, were in favor of the notion; others denied the existence of such an idea. Inada remained clear-cut in his own assertions. Everything done by the local Soviet forces, he insisted, must have been effected with the permission of Moscow; it was customary for the USSR not to abandon what it had once started. The Japanese Army never really thought that the Soviet Union would withdraw just as the result of diplomatic approaches. Therefore, from the outset, preparations were made to deal the Russians one decisive blow. Inada had recommended his plan, with its clear restrictions, to his colleagues and superiors; the scheme, he says, was approved 14 July "all the way up the chain of command, through the Army general staff and the ministry of war, with unexpected ease." The only real opposition, Inada recalled, came from the navy, whose staff advised the army operations staff, in all sincerity, to give up the idea of strategic reconnaissance. Inada adhered to his opinion stubbornly. He never forgot the grave look on the face of Captain Kusaka, the UN operations section chief, as the latter gave in reluctantly. The navy view was that the Changkufeng affair typified the army's aggressive policies as opposed to relative passivity on the part of the navy. Like Kusaka, Japanese Navy interviewees shared the fear that Changkufeng might prove to be the most dangerous military confrontation ever to occur between the USSR and Japan. In view of navy objections, one wonders where Inada could have drawn support for his concept of reconnaissance in force. If one accepts the comments contained in a letter from a navy ministry captain, Takagi Sokichi, to Baron Harada Kumao at the beginning of August, in the army and in a portion of the navy there existed "shallow-minded fellows who are apt to take a firm stand in the blind belief that the USSR would not really rise against us, neglecting the fact that the Russians had foreseen our weak points." Takagi also had violent things to say about "white-livered" Gaimusho elements that were playing up to the army. Although Takagi's remarks, expressed in confidence, were sharp, cautious injunctions were being delivered by the high command to the new Korea Army commander, General Nakamura Kotaro, who was about to leave for Seoul to replace Koiso. Nakamura's attitude was crucial for the course and outcome of the Changku…

    3.175 Fall and Rise of China: Soviet-Japanese Border Conflicts Nov 10, 2025
    Show notes

    Last time we spoke about the Changsha fire. Chiang Kai-shek faced a brutal choice: defend Wuhan to the last man or flood the land to slow the invaders. He chose both, pushing rivers and rallying a fractured army as Japanese forces pressed along the Yangtze. Fortresses at Madang held long, but the cost was high—troops lost, civilians displaced, a city's heart burning in the night. Wuhan fell after months of brutal fighting, yet the battle did not break China's will. Mao Zedong urged strategy over martyrdom, preferring to drain the enemy and buy time for a broader struggle. The Japanese, though victorious tactically, found their strength ebbing, resource strains, supply gaps, and a war that felt endless. In the wake of Wuhan, Changsha stood next in the Japanese crosshairs, its evacuation and a devastating fire leaving ash and memory in its wake. Behind these prices, political currents swirled. Wang Jingwei defected again, seeking power beyond Chiang's grasp, while Chongqing rose as a western bastion of resistance. The war hardened into a protracted stalemate, turning Japan from an aggressive assailant into a wary occupier, and leaving China to endure, persist, and fight on. #175 The Soviet-Japanese Border Conflicts Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. So based on the title of this one, you probably can see we are taking a bit of a detour. For quite some time we have focused on the Japanese campaigns into China proper 1937-1938. Now the way the second sino-japanese war is traditionally broken down is in phases. 1937-1938, 1939-1942 and 1942-1945. However there is actually even more going on in China aside from the war with Japan. In Xinjiang province a large full blown Islamic revolution breaks out in 1937. We will be covering that story at a later date, but another significant event is escalating border skirmishes in Manchukuo. Now these border skirmishes had been raging ever since the USSR consolidated its hold over the far east. We talked about some of those skirmishes prior to the Sino-Soviet war in 1929. However when Japan created the puppet government of Manchukuo, this was a significant escalation in tensions with the reds. Today we are going to talk about the escalating border conflicts between the Soviets and Japan. A tongue of poorly demarcated land extends southeast from Hunchun, hugging the east bank of the Tumen River between Lake Khasan to the east and Korea to the west. Within this tongue stands Changkufeng Hill, one of a long chain of highlands sweeping from upstream along the rivers and moors toward the sea. The twin-peaked hill sits at the confluence area several miles northwest of the point where Manchuria, Korea, and the Russian Far East meet. The hill's shape reminded Koreans of their changgo, which is a long snare drum constricted at the center and tapped with the hands at each end. When the Manchus came to the Tumen, they rendered the phonetic sounds into three ideographic characters meaning "taut drum peaks" or Chang-ku-feng. The Japanese admired the imagery and preserved the Chinese readings, which they pronounce Cho-ko-ho. From their eastern vantage, the Russians called it Zaozernaya, "hill behind the lake." Soviet troops referred to it as a sugar-loaf hill. For many years, natives and a handful of officials in the region cultivated a relaxed attitude toward borders and sovereignty. Even after the Japanese seized Manchuria in 1931, the issue did not immediately come to a head. With the expansion of Manchukuo and the Soviet Far East under Stalin's Five-Year plans, both sides began to attend more closely to frontier delimitation. Whenever either party acted aggressively, force majeure was invoked to justify the unexpected and disruptive events recognized in international law. Most often, these incidents erupted along the eastern Manchurian borders with the USSR or along the 350-mile frontier south of Lake Khanka, each skirmish carrying the seeds of all-out warfare. Now we need to talk a little bit about border history. The borders in question essentially dated to pacts concluded by the Qing dynasty and the Tsardom. Between the first Sino-Russian Treaty of Nerchinsk in 1689 and the Mukden Agreement of 1924, there were over a dozen accords governing the borders. Relevant to Changkufeng were the basic 15-article Convention of Peking, supplementing the Tientsin Treaties of November 1860, some maps made in 1861, and the eight-article Hunchun Border Protocol of 1886. By the 1860 treaty, the Qing ceded to Tsarist Russia the entire maritime province of Siberia, but the meaning of "lands south of Lake Khanka" remained rather vague. Consequently, a further border agreement was negotiated in June 1861 known as "the Lake Khanka Border Pact", by which demarcations were drawn on maps and eight wooden markers erected. The border was to run from Khanka along ridgelines between the Hunchun River and the sea, past Suifenho and Tungning, terminating about 6 miles from the mouth of the Tumen. Then a Russo-Chinese commission established in 1886 drew up the Hunchun Border Pact, proposing new or modified markers along the 1860–1861 lines and arranging a Russian resurvey. However, for the Japanese, in 1938, the Chinese or Manchu texts of the 1886 Hunchun agreement were considered controlling. The Soviets argued the border ran along every summit west of Khasan, thereby granting them jurisdiction over at least the eastern slopes of all elevations, including Changkufeng and Shachaofeng. Since the Qing dynasty and the house of Romanov were already defunct, the new sovereignties publicly appealed to opposing texts, and the Soviet side would not concede that the Russian-language version had never been deemed binding by the Qing commissioners. Yet, even in 1938, the Japanese knew that only the Chinese text had survived or could be located. Now both the Chinese and Russian military maps generally drew the frontier along the watershed east of Khasan; this aligned with the 1861 readings based on the Khanka agreement. The Chinese Republican Army conducted new surveys sometime between 1915 and 1920. The latest Chinese military map of the Changkufeng area drew the border considerably closer to the old "red line" of 1886, running west of Khasan but near the shore rather than traversing the highland crests. None of the military delimitations of the border was sanctified by an official agreement. Hence, the Hunchun Protocol, whether well known or not, invaluable or worthless, remained the only government-to-government pact dealing with the frontiers. Before we jump into it, how about a little summary of what became known as the Soviet-Japanese border conflicts. The first major conflict would obviously be the Russo-Japanese war of 1904-1905. Following years of conflict between the Russian Empire and Japan culminating in the costly Battle of Tsushima, Tsar Nicholas II's government sought peace, recognizing Japan's claims to Korea and agreeing to evacuate Manchuria. From 1918 to 1920, the Imperial Japanese Army, under Emperor Taishō after the death of Meiji, assisted the White Army and Alexander Kerensky against the Bolshevik Red Army. They also aided the Czechoslovak Legion in Siberia to facilitate its return to Europe after an Austrian-Hungarian armoured train purportedly went astray. By 1920, with Austria-Hungary dissolved and Czechoslovakia established two years earlier, the Czechoslovak Legion reached Europe. Japan withdrew from the Russian Revolution and the Civil War in 1922. Following Japan's 1919-1920 occupations and the Soviet intervention in Mongolia in 1921, the Republic of China also withdrew from Outer Mongolia in 1921. In 1922, after capturing Vladivostok in 1918 to halt Bolshevik advances, Japanese forces retreated to Japan as Bolshevik power grew and the postwar fatigue among combatants increased. After Hirohito's invasion of Manchuria in 1931–1932, following Taishō's death in 1926, border disputes between Manchukuo, the Mongolian People's Republic, and the Soviet Union increased. Many clashes stemmed from poorly defined borders, though some involved espionage. Between 1932 and 1934, the Imperial Japanese Army reported 152 border disputes, largely tied to Soviet intelligence activity in Manchuria, while the Soviets accused Japan of 15 border violations, six air intrusions, and 20 cases of "spy smuggling" in 1933 alone. Numerous additional violations followed in the ensuing years. By the mid-1930s, Soviet-Japanese diplomacy and trust had deteriorated further, with the Japanese being openly labeled "fascist enemies" at the Seventh Comintern Congress in July 1935. Beginning in 1935, conflicts significantly escalated. On 8 January 1935, the first armed clash, known as the Halhamiao incident, took place on the border between Mongolia and Manchukuo. Several dozen cavalrymen of the Mongolian People's Army crossed into Manchuria near disputed fishing grounds and engaged an 11‑man Manchukuo Imperial Army patrol near the Buddhist temple at Halhamiao, led by a Japanese military advisor. The Manchukuo Army sustained 6 wounded and 2 dead, including the Japanese officer; the Mongols suffered no casualties and withdrew after the Japanese sent a punitive expedition to reclaim the area. Two motorized cavalry companies, a machine‑gun company, and a tankette platoon occupied the position for three weeks without resistance. In June 1935, the first direct exchange of fire between the Japanese and Soviets occurred when an 11‑man Japanese patrol west of Lake Khanka was attacked by six Soviet horsemen, reportedly inside Manchukuo territory. In the firefight, one Soviet soldier was killed and two horses were captured. The Japanese requested a joint investigation, but the Soviets rejected the proposal. In October 1935, nine Japanese and 32 Manchukuoan border guards were establishing a post about 20 kilometers north of Suifenho when they were attacked by 50 Soviet soldiers. The Soviets opened fire with rifles and five heavy machine guns. Two Japanese and four Manchukuoan soldiers were killed, and another five were wounded. The Manchukuoan foreign affairs representative lodged a verbal protest with the Soviet consul at Suifenho. The Kwantung Army of Japan also sent an intelligence officer to investigate the clash. On 19 December 1935, a Manchukuoan unit reconnoitering southwest of Buir Lake clashed with a Mongolian party, reportedly capturing 10 soldiers. Five days later, 60 truck‑borne Mongolian troops assaulted the Manchukuoans and were repulsed, at the cost of three Manchukuoan dead. On the same day, at Brunders, Mongolian forces attempted three times to drive out Manchukuoan outposts, and again at night, but all attempts failed. Further small attempts occurred in January, with Mongolians using airplanes for reconnaissance. The arrival of a small Japanese force in three trucks helped foil these attempts; casualties occurred on both sides, though Mongolian casualties are unknown aside from 10 prisoners taken. In February 1936, Lieutenant-Colonel Sugimoto Yasuo was ordered to form a detachment from the 14th Cavalry Regiment to "drive the Outer Mongol intruders from the Olankhuduk region," a directive attributed to Lieutenant-General Kasai Heijuro. Sugimoto's detachment included cavalry guns, heavy machine guns, and tankettes. They faced a force of about 140 Mongolians equipped with heavy machine guns and light artillery. On February 12, Sugimoto's men drove the Mongolians south, at the cost of eight Japanese killed, four wounded, and one tankette destroyed. The Japanese began to withdraw, but were attacked by 5–6 Mongolian armored cars and two bombers, which briefly disrupted the column. The situation was stabilized when the Japanese unit received artillery support, allowing them to destroy or repel the armored cars. In March 1936, the Tauran incident occurred. In this clash, both the Japanese Army and the Mongolian Army deployed a small number of armored fighting vehicles and aircraft. The incident began when 100 Mongolian and six Soviet troops attacked and occupied the disputed village of Tauran, Mongolia, driving off the small Manchurian garrison. They were supported by light bombers and armored cars, though the bombing sorties failed to inflict damage on the Japanese, and three bombers were shot down by Japanese heavy machine guns. Local Japanese forces counter-attacked, conducting dozens of bombing sorties and finally assaulting Tauran with 400 men and 10 tankettes. The result was a Mongolian rout, with 56 Mongolian soldiers killed, including three Soviet advisors, and an unknown number wounded. Japanese losses were 27 killed and 9 wounded. Later in March 1936, another border clash occurred between Japanese and Soviet forces. Reports of border violations prompted the Japanese Korean Army to send ten men by truck to investigate, but the patrol was ambushed by 20 Soviet NKVD soldiers deployed about 300 meters inside territory claimed by Japan. After suffering several casualties, the Japanese patrol withdrew and was reinforced with 100 men, who then drove off the Soviets. Fighting resumed later that day when the NKVD brought reinforcements. By nightfall, the fighting had ceased and both sides had pulled back. The Soviets agreed to return the bodies of two Japanese soldiers who had died in the fighting, a development viewed by the Japanese government as encouraging. In early April 1936, three Japanese soldiers were killed near Suifenho in another minor affray. This incident was notable because the Soviets again returned the bodies of the fallen servicemen. In June 1937, the Kanchazu Island incident occurred on the Amur River along the Soviet–Manchukuo border. Three Soviet gunboats crossed the river's center line, disembarked troops, and occupied Kanchazu Island. Japanese forces from the IJA 1st Division, equipped with two horse-drawn 37 mm artillery pieces, quickly established improvised firing positions and loaded their guns with both high-explosive and armor-piercing shells. They shelled the Soviet vessels, sinking the lead gunboat, crippling the second, and driving off the third. Japanese troops subsequently fired on the swimming crewmen from the sunken ships using machine guns. Thirty-seven Soviet soldiers were killed, while Japanese casualties were zero. The Japanese Ministry of Foreign Affairs protested and demanded the Soviet forces withdraw from the island. The Soviet leadership, apparently shocked by the incident and reluctant to escalate, agreed to evacuate their troops. By 1938 the border situation had deteriorated. The tangled terrain features, mountain, bog, stream, forest, and valley, would have complicated even careful observers' discernment of the old red line drawn in 1886. Fifty years later, the markers themselves had undergone a metamorphosis. Japanese investigators could find, at most, only 14 to 17 markers standing fairly intact between the Tumen estuary and Khanka—roughly one every 25 miles at best. The remainder were missing or ruined; five were found in new locations. Marker "K," for example, was 40 meters deepe…

    3.174 Fall and Rise of China: Changsha Fire Nov 03, 2025
    Show notes

    Last time we spoke about the fall of Wuhan. In a country frayed by war, the Yangtze became a pulsing artery, carrying both hunger and hope. Chiang Kai-shek faced a brutal choice: defend Wuhan to the last man, or flood the rivers to buy time. He chose both, setting sullen floodwaters loose along the Yellow River to slow the invaders, a temporary mercy that spared some lives while ripping many from their homes. On the river's banks, a plethora of Chinese forces struggled to unite. The NRA, fractured into rival zones, clung to lines with stubborn grit as Japanese forces poured through Anqing, Jiujiang, and beyond, turning the Yangtze into a deadly corridor. Madang's fortifications withstood bombardment and gas, yet the price was paid in troops and civilians drowned or displaced. Commanders like Xue Yue wrestled stubbornly for every foothold, every bend in the river. The Battle of Wanjialing became a symbol: a desperate, months-long pincer where Chinese divisions finally tightened their cordon and halted the enemy's flow. By autumn, the Japanese pressed onward to seize Tianjiazhen and cut supply lines, while Guangzhou fell to a ruthless blockade. The Fall of Wuhan loomed inevitable, yet the story remained one of fierce endurance against overwhelming odds. #174 The Changsha Fire Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. In the summer of 1938, amid the upheaval surrounding Chiang Kai-shek, one of his most important alliances came to an end. On June 22, all German advisers to the Nationalist government were summoned back; any who refused would be deemed guilty of high treason. Since World War I, a peculiar bond had tied the German Weimar Republic and China: two fledgling states, both weak and only partially sovereign. Under the Versailles Treaty of 1919, Germany had lost extraterritorial rights on Chinese soil, which paradoxically allowed Berlin to engage with China as an equal partner rather than a traditional colonizer. This made German interests more welcome in business and politics than those of other Western powers. Chiang's military reorganization depended on German officers such as von Seeckt and von Falkenhausen, and Hitler's rise in 1933 had not immediately severed the connection between the two countries. Chiang did not share Nazi ideology with Germany, but he viewed Berlin as a potential ally and pressed to persuade it to side with China rather than Japan as China's principal East Asian, anti-Communist partner. In June 1937, H. H. Kung led a delegation to Berlin, met Hitler, and argued for an alliance with China. Yet the outbreak of war and the Nationalists' retreat to Wuhan convinced Hitler's government to align with Japan, resulting in the recall of all German advisers. Chiang responded with a speech praising von Falkenhausen, insisting that "our friend's enemy is our enemy too," and lauding the German Army's loyalty and ethics as a model for the Chinese forces. He added, "After we have won the War of Resistance, I believe you'll want to come back to the Far East and advise our country again." Von Falkenhausen would later become the governor of Nazi-occupied Belgium, then be lauded after the war for secretly saving many Jewish lives. As the Germans departed, the roof of the train transporting them bore a prominent German flag with a swastika, a prudent precaution given Wuhan's vulnerability to air bombardment. The Japanese were tightening their grip on the city, even as Chinese forces, numbering around 800,000, made a stubborn stand. The Yellow River floods blocked northern access, so the Japanese chose to advance via the Yangtze, aided by roughly nine divisions and the might of the Imperial Navy. The Chinese fought bravely, but their defenses could not withstand the superior technology of the Japanese fleet. The only substantial external aid came from Soviet pilots flying aircraft bought from the USSR as part of Stalin's effort to keep China in the war; between 1938 and 1940, some 2,000 pilots offered their services. From June 24 to 27, Japanese bombers relentlessly pounded the Madang fortress along the Yangtze until it fell. A month later, on July 26, Chinese defenders abandoned Jiujiang, southeast of Wuhan, and its civilian population endured a wave of atrocities at the hands of the invaders. News of Jiujiang's fate stiffened resolve. Chiang delivered a pointed address to his troops on July 31, arguing that Wuhan's defense was essential and that losing the city would split the country into hostile halves, complicating logistics and movement. He warned that Wuhan's defense would also be a spiritual test: "the place has deep revolutionary ties," and public sympathy for China's plight was growing as Japanese atrocities became known. Yet Chiang worried about the behavior of Chinese soldiers. He condemned looting as a suicidal act that would destroy the citizens' trust in the military. Commanders, he warned, must stay at their posts; the memory of the Madang debacle underscored the consequences of cowardice. Unlike Shanghai, Wuhan had shelters, but he cautioned against retreating into them and leaving soldiers exposed. Officers who failed in loyalty could expect no support in return. This pep talk, combined with the belief that the army was making a last stand, may have slowed the Japanese advance along the Yangtze in August. Under General Xue Yue, about 100,000 Chinese troops pushed back the invaders at Huangmei. At Tianjiazhen, thousands fought until the end of September, with poison gas finally forcing Japanese victory. Yet even then, Chinese generals struggled to coordinate. In Xinyang, Li Zongren's Guangxi troops were exhausted; they expected relief from Hu Zongnan's forces, but Hu instead withdrew, allowing Japan to capture the city without a fight. The fall of Xinyang enabled Japanese control of the Ping-Han railway, signaling Wuhan's doom. Chiang again spoke to Wuhan's defenders, balancing encouragement with a grim realism about possible loss. Although Wuhan's international connections were substantial, foreign aid would be unlikely. If evacuation became necessary, the army should have a clear plan, including designated routes. He recalled the disastrous December retreat from Nanjing, where "foreigners and Chinese alike turned it into an empty city." Troops had been tired and outnumbered; Chiang defended the decision to defend Nanjing, insisting the army had sacrificed itself for the capital and Sun Yat-sen's tomb. Were the army to retreat again, he warned, it would be the greatest shame in five thousand years of Chinese history. The loss of Madang was another humiliation. By defending Wuhan, he argued, China could avenge its fallen comrades and cleanse its conscience; otherwise, it could not honor its martyrs. Mao Zedong, observing the situation from his far-off base at Yan'an, agreed strongly that Chiang should not defend Wuhan to the death. He warned in mid-October that if Wuhan could not be defended, the war's trajectory would shift, potentially strengthening the Nationalists–Communists cooperation, deepening popular mobilization, and expanding guerrilla warfare. The defense of Wuhan, Mao argued, should drain the enemy and buy time to advance the broader struggle, not become a doomed stalemate. In a protracted war, some strongholds might be abandoned temporarily to sustain the longer fight. The Japanese Army captured Wuchang and Hankou on 26 October and captured Hanyang on the 27th, which concluded the campaign in Wuhan. The battle had lasted four and a half months and ended with the Nationalist army's voluntary withdrawal. In the battle itself, the Japanese army captured Wuhan's three towns and held the heartland of China, achieving a tactical victory. Yet strategically, Japan failed to meet its objectives. Imperial Headquarters believed that "capturing Hankou and Guangzhou would allow them to dominate China." Consequently, the Imperial Conference planned the Battle of Wuhan to seize Wuhan quickly and compel the Chinese government to surrender. It also decreed that "national forces should be concentrated to achieve the war objectives within a year and end the war against China." According to Yoshiaki Yoshimi and Seiya Matsuno, Hirohito authorized the use of chemical weapons against China by specific orders known as rinsanmei. During the Battle of Wuhan, Prince Kan'in Kotohito transmitted the emperor's orders to deploy toxic gas 375 times between August and October 1938. Another memorandum uncovered by Yoshimi indicates that Prince Naruhiko Higashikuni authorized the use of poison gas against the Chinese on 16 August 1938. A League of Nations resolution adopted on 14 May condemned the Imperial Japanese Army's use of toxic gas. Japan's heavy use of chemical weapons against China was driven by manpower shortages and China's lack of poison gas stockpiles to retaliate. Poison gas was employed at Hankou in the Battle of Wuhan to break Chinese resistance after conventional assaults had failed. Rana Mitter notes that, under General Xue Yue, approximately 100,000 Chinese troops halted Japanese advances at Huangmei, and at the fortress of Tianjiazhen, thousands fought until the end of September, with Japanese victory secured only through the use of poison gas. Chinese generals also struggled with coordination at Xinyang; Li Zongren's Guangxi troops were exhausted, and Hu Zongnan's forces, believed to be coming to relieve them, instead withdrew. Japan subsequently used poison gas against Chinese Muslim forces at the Battle of Wuyuan and the Battle of West Suiyuan. However, the Chinese government did not surrender with the loss of Wuhan and Guangzhou, nor did Japan's invasion end with Wuhan and Guangzhou's capture. After Wuhan fell, the government issued a reaffirmation: "Temporary changes of advance and retreat will not shake our resolve to resist the Japanese invasion," and "the gain or loss of any city will not affect the overall situation of the war." It pledged to "fight with even greater sorrow, greater perseverance, greater steadfastness, greater diligence, and greater courage," dedicating itself to a long, comprehensive war of resistance. In the Japanese-occupied rear areas, large armed anti-Japanese forces grew, and substantial tracts of territory were recovered. As the Japanese army themselves acknowledged, "the restoration of public security in the occupied areas was actually limited to a few kilometers on both sides of the main transportation lines." Thus, the Battle of Wuhan did not merely inflict a further strategic defeat on Japan; it also marked a turning point in Japan's strategic posture, from offense to defense. Due to the Nationalist Army's resolute resistance, Japan mobilized its largest force to date for the attack, about 250,000 personnel, who were replenished four to five times over the battle, for a total of roughly 300,000. The invaders held clear advantages in land, sea, and air power and fought for four and a half months. Yet they failed to annihilate the Nationalist main force, nor did they break the will to resist or the army's combat effectiveness. Instead, the campaign dealt a severe blow to the Japanese Army's vitality. Japanese-cited casualties totaled 4,506 dead and 17,380 wounded for the 11th Army; the 2nd Army suffered 2,300 killed in action, 7,600 wounded, and 900 died of disease. Including casualties across the navy and the air force, the overall toll was about 35,500. By contrast, the Nationalist Government Military Commission's General Staff Department, drawing on unit-level reports, calculated Japanese casualties at 256,000. The discrepancy between Japanese and Nationalist tallies illustrates the inflationary tendencies of each side's reporting. Following Wuhan, a weakened Japanese force confronted an extended front. Unable to mount large-scale strategic offensives, unlike Shanghai, Xuzhou, or Wuhan itself, the Japanese to a greater extent adopted a defensive posture. This transition shifted China's War of Resistance from a strategic defensive phase into a strategic stalemate, while the invaders found themselves caught in a protracted war—a development they most disliked. Consequently, Japan's invasion strategy pivoted: away from primary frontal offensives toward a greater reliance on political inducements with secondary military action, and toward diverting forces to "security" operations behind enemy lines rather than pushing decisive frontal campaigns. Japan, an island nation with limited strategic resources, depended heavily on imports. By the time of the Marco Polo Bridge Incident, Japan's gold reserves,including reserves for issuing banknotes, amounted to only about 1.35 billion yen. In effect, Japan's currency reserves constrained the scale of the war from the outset. The country launched its aggression while seeking an early solution to the conflict. To sustain its war of aggression against China, the total value of military supplies imported from overseas in 1937 reached approximately 960 million yen. By June of the following year, for the Battle of Wuhan, even rifles used in training were recalled to outfit the expanding army. The sustained increase in troops also strained domestic labor, food, and energy supplies. By 1939, after Wuhan, Japan's military expenditure had climbed to about 6.156 billion yen, far exceeding national reserves. This stark reality exposed Japan's economic fragility and its inability to guarantee a steady supply of military materiel, increasing pressure on the leadership at the Central Command. The Chief of Staff and the Minister of War lamented the mismatch between outward strength and underlying weakness: "Outwardly strong but weak is a reflection of our country today, and this will not last long." In sum, the Wuhan campaign coincided with a decline in the organization, equipment, and combat effectiveness of the Japanese army compared with before the battle. This erosion of capability helped drive Japan to alter its political and military strategy, shifting toward a method of inflicting pressure on China and attempting to "use China to control China", that is, fighting in ways designed to sustain the broader war effort. Tragically a major element of Chiang Kai-shek's retreat strategy was the age-old "scorched earth" policy. In fact, China originated the phrase and the practice. Shanghai escaped the last-minute torching because of foreigners whose property rights were protected. But in Nanjing, the burning and destruction began with increasing zeal. What could not be moved inland, such as remaining rice stocks, oil in tanks, and other facilities, was to be blown up or devastated. Civilians were told to follow the army inland, to rebuild later behind the natural barrier of Sichuan terrain. Many urban residents complied, but the peasantry did not embrace the plan. The scorched-earth policy served as powerful propaga…

    3.173 Fall and Rise of China: Fall of Wuhan Oct 27, 2025
    Show notes

    Last time we spoke about the beginning of the Wuhan Campaign. As Japanese forces pressed toward central China, Chiang Kai-shek faced a brutal choice: defend Wuhan with costly sieges or unleash a dangerous flood to buy time. The Yellow River breached its banks at Huayuankou, sending a wall of water racing toward villages, railways, and fields. The flood did not erase the enemy; it bought months of breathing room for a battered China, but at a terrible toll to civilians who lost homes, farms, and lives. Within Wuhan's orbit, a mosaic of Chinese forces struggled to unite. The NRA, split into competing war zones and factions, numbered about 1.3 million but fought with uneven equipment and training. The Japanese, deploying hundreds of thousands, ships, and air power, pressed from multiple angles: Anqing, Madang, Jiujiang, and beyond, using riverine forts and amphibious landings to turn the Yangtze into a deadly artery. Yet courage endured as troops held lines, pilots challenged the skies, and civilians, like Wang Guozhen, who refused to betray his country, chose defiance over surrender. The war for Wuhan was not a single battle but a testament to endurance in the face of overwhelming odds. #173 The Fall of Wuhan Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson. But, before we start I want to also remind you this podcast is only made possible through the efforts of Kings and Generals over at Youtube. Perhaps you want to learn more about the history of Asia?

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel where I cover the history of China and Japan from the 19th century until the end of the Pacific War. In the last episode we began the Battle of Wuhan. Japan captured Anqing and gained air access to Jiujiang, Chinese defenses around the Yangtze River were strained. The southern Yangtze's Ninth War Zone held two key garrisons: one west of Poyang Lake and another in Jiujiang. To deter Japanese assault on Jiujiang, China fortified Madang with artillery, mines, and bamboo booms. On June 24, Japan conducted a surprise Madang landing while pressing south along the Yangtze. Madang's fortress withstood four assaults but suffered heavy bombardment and poison gas. Chinese leadership failures contributed to the fall: Li Yunheng, overseeing Madang, was away at a ceremony, leaving only partial contingents, primarily three battalions from marine corps units and the 313th regiment of the 53rd division, participating, totaling under five battalions. Reinforcements from Pengze were misrouted by Li's orders, arriving too late. Madang fell after three days. Chiang Kai-shek retaliated with a counterattack and rewarded units that recaptured Xiangshan, but further progress was blocked. Li Yunheng was court-martialed, and Xue Weiying executed. Madang's loss opened a corridor toward Jiujiang. The Japanese needed weeks to clear minefields, sacrificing several ships in the process. With roughly 200,000 Chinese troops in the Jiujiang–Ruichang zone under Xue Yue and Zhang Fukui, the Japanese captured Pengze and then Hukou, using poison gas again during the fighting. The Hukou evacuation cut off many non-combat troops, with over 1,800 of 3,100 soldiers successfully evacuated and more than 1,300 missing drowned in the lake. Two weeks after Hukou's fall, the Japanese reached Jiujiang and overtook it after a five-day battle. The retreat left civilians stranded, and the Jiujiang Massacre followed: about 90,000 civilians were killed, with mass executions of POWs, rapes, and widespread destruction of districts, factories, and transport. Subsequently, the Southern Riverline Campaign saw Japanese detachments along the river advance westward, capturing Ruichang, Ruoxi, and other areas through October, stretching Chinese defenses thin as Japan pressed toward Wuchang and beyond. On July 26, 1938, the Japanese occupied Jiujiang and immediately divided their forces into three routes: advancing toward De'an and Nanchang, then striking Changsha, severing the Yue-Han Railway, and surrounding Wuhan in an effort to annihilate the Chinese field army. The advance of the 101st and 106th Infantry Divisions slowed south of the Yangtze River, yet the Central China Expeditionary Army remained intent on seizing Ruichang and De'an to cut off Chinese forces around Mount Lu. To this end, the 9th and 27th Infantry Divisions were deployed to the sector, with the 9th regarded as an experienced unit that had fought in earlier campaigns, while the 27th was newly formed in the summer of 1938; this contrast underscored the rapidly expanding scope of the war in China as the Japanese Army General Staff continued mobilizing reservists and creating new formations. According to the operational plan, the 101st and 106th Divisions would push south toward De'an to pin Chinese defenders, while the 9th and 27th Divisions would envelop Chinese forces south of the river. Okamura Yasuji ordered five battalions from the 9th to move toward De'an via Ruichang, and the Hata Detachment was tasked with securing the area northwest of Ruichang to protect the 9th's flank. North of the Yangtze, the 6th Infantry Division was to move from Huangmei to Guangji, with Tianjiazhen as the ultimate objective; capturing Tianjiazhen would allow the 11th Army to converge on Wuhan from both north and south of the river. The operation began when the 9th Division landed at Jiujiang, threatening the left flank of the Jinguanqiao line. The Chinese responded by deploying the 1st Corps to counter the 9th Division's left flank, which threatened the Maruyama Detachment's lines of communication. The Maruyama Detachment counterattacked successfully, enabling the rest of the 9th Division to seize Ruichang on August 24; on the same day, the 9th attacked the 30th Army defending Mount Min. The Chinese defense deteriorated on the mountain, and multiple counterattacks by Chinese divisions failed, forcing the 1st Corps to retreat to Mahuiling. The seizure of Ruichang and the surrounding area was followed by a wave of atrocities, with Japanese forces inflicting substantial casualties, destroying houses, and damaging property, and crimes including murder, rape, arson, torture, and looting devastating many villages and livelihoods in the Ruichang area. After Ruichang and Mount Min fell, the Maruyama Detachment and the 106th Infantry Division advanced on Mahuiling, seeking to encircle Chinese forces from the northwest, with the 106th forming the inner ring and the Maruyama Detachment the outer ring; this coordination led to Mahuiling's fall on September 3. The 27th Infantry Division, arriving in late August, landed east of Xiaochikou, providing the manpower to extend Japanese offensives beyond the Yangtze's banks and outflank Chinese defenders along the river. Its main objective was to seize the Rui-wu highway, a vital route for the continued advance toward Wuhan. After the fall of Mahuiling, Japanese command altered its strategy. The 11th Army ordered the Maruyama Detachment to rejoin the 9th Infantry Division and press westward, while the 101st Infantry Division was to remain at Mahuiling and push south toward De'an along with the 106th Infantry Division. This divergent or "eccentric" offensive aimed to advance on Wuhan while protecting the southern flank. The renewed offensive began on September 11, 1938, with the 9th Infantry Division and Hata Detachment advancing west along the Rui-yang and Rui-wu highways toward Wuhan, followed days later by the 27th Infantry Division. Initially, the Japanese made solid progress from Ruichang toward a line centered on Laowuge, but soon faced formidable Chinese defenses. The 9th and 27th Divisions confronted the Chinese 2nd Army Corps, which had prepared in-depth positions in the mountains west of Sanchikou and Xintanpu. The 27th Division encountered stiff resistance from the 18th and 30th Corps, and although it captured Xiaoao by September 24, its vanguard advancing west of Shujie came under heavy attack from the 91st, 142nd, 60th, and 6th Reserve Infantry Divisions, threatening to encircle it. Only the southward advance of the 101st and 106th Divisions relieved the pressure, forcing the Chinese to redeploy the 91st and 6th Reserve Divisions to the south and thereby loosening the 27th's grip. After the redeployment, the 9th and 27th Divisions resumed their push. The 9th crossed the Fu Shui on October 9 and took Sanjikou on October 16, while the 27th seized Xintanpu on October 18. The Hata Detachment followed, capturing Yangxin on October 18 and Ocheng on October 23, further tightening Japanese control over the highways toward Wuhan. By mid-October, 11th Army commander Okamura Yasuji resolved to sever the Guangzhou-Hankou railway to disrupt Chinese lines. On October 22, the 9th and 27th Divisions attacked toward Jinniu and Xianning. By October 27, the 9th had captured Jinniu and cut the railway; the 27th Division extended the disruption further south. These actions effectively isolated Wuchang from the south, giving the Imperial Japanese Army greater leverage over the southern approaches to Wuhan. The push south by the 101st and 106th Infantry Divisions pressed toward De'an, where they encountered the entrenched Chinese 1st Army Corps. The offensive began on September 16 and by the 24th, elements of the 27th Division penetrated deep into the area west of Baishui Street and De'an's environs. Recognizing the growing crisis, Xue Yue mobilized the nearby 91st and 142nd Divisions, who seized Nanping Mountain along the Ruiwu Line overnight, effectively cutting off the 27th Division's retreat. Fierce combat on the 25th and 26th saw Yang Jialiu, commander of the 360th Regiment of the 60th Division, die a heroic death. Zhang Zhihe, chief of staff of the 30th Group Army and an underground CCP member, commanded the newly formed 13th Division and the 6th Division to annihilate the Suzuki Regiment and recapture Qilin Peak. Learning of the 27th Division's trap, Okamura Yasuji panicked and, on the 25th, urgently ordered the 123rd, 145th, and 147th Infantry Regiments and mountain artillery of the 106th Division on the Nanxun Line, along with the 149th Regiment of the 101st Division on the Dexing Line, to rush to Mahuiling and Xingzi. To adapt to mountain warfare, some units were temporarily converted to packhorse formations. On the 27th, the 106th Division broke through the Wutailing position with force, splitting into two groups and pushing toward Erfangzheng and Lishan. By the 28th, the three regiments and mountain artillery of the 106th Division advanced into the mountain villages of Wanjialing, Leimingguliu, Shibaoshan, Nantianpu, Beixijie, and Dunshangguo, about 50 li west of De'an. On the same day, the 149th Regiment of the 101st Division entered the Wanjialing area and joined the 106th Division. Commanded by Lieutenant General Junrokuro Matsuura, the 106th Division sought to break out of Baicha and disrupt the Nanwu Highway to disrupt the Chinese retreat from De'an. At this juncture, Xue Yue's corps perceived the Japanese advance as a predatory, wolf-like maneuver and deemed it a strategic opportunity to counterattack. He resolved to pull forces from Dexing, Nanxun, and Ruiwu to envelop the enemy near Wanjialing, with the aim of annihilating them. Thus began a desperate, pivotal battle between China and Japan in northern Jiangxi, centered on the Wanjialing area. The Japanese 106th Division found its rear communications cut off around September 28, 1938, as the Chinese blockade tightened. Despite the 27th Division's severed rear and its earlier defeat at Qilin Peak, Okamura Yasuji ordered a renewed push to relieve the besieged 106th by directing the 27th Division to attack Qilin Peak and advance east of Baishui Street. In this phase, the 27th Division dispatched the remnants of its 3rd Regiment to press the assault on Qilin Peak, employing poison gas and briefly reaching the summit. On September 29, the 142nd Division of the 32nd Army, under Shang Zhen, coordinated with the 752nd Regiment of the same division to launch a fierce counterattack on Qilin Peak at Zenggai Mountain west of Xiaoao. After intense fighting, they reclaimed the peak, thwarting the 27th Division's bid to move eastward to aid the 106th. Concurrently, a portion of the 123rd Regiment of the 106th Division attempted a breakout west of Baishui Street. Our 6th and 91st Divisions responded with a determined assault from the east of Xiaoao, blocking the 123rd Regiment east of Baishui Street. The victories at Qilin Peak and Baishui Street halted any merger between the eastern and western Japanese forces, enabling the Chinese army to seal the pocket and create decisive conditions for encircling the 106th Division and securing victory in the Battle of Wanjialing. After the setback at Qilin Peak, Division Commander Masaharu Homma, defying Okamura Yasuji's orders to secure Baishui Street, redirected his focus to Tianhe Bridge under a pretext of broader operations. He neglected the heavily encircled 106th Division and pivoted toward Xintanpu. By September 30, Chinese forces attacked from both the east and west, with the 90th and 91st Divisions joining the assault on the Japanese positions. On October 1, the Japanese, disoriented and unable to pinpoint their own unit locations, telegrammed Okamura Yasuji for air support. On October 2, the First Corps received orders to tighten the encirclement and annihilate the enemy forces. Deployments were made to exploit a numerical advantage and bolster morale, placing the Japanese in a desperate position. On October 3, 1938, the 90th and 91st Divisions launched a concerted attack on Nantianpu, delivering heavy damage to the Japanese force and showering Leimingguliu with artillery fire that endangered the 106th Division headquarters. By October 5, Chinese forces reorganized: the 58th Division of the 74th Army advanced from the south, the 90th Division of the 4th Army from the east, portions of the 6th and 91st Divisions from the west, and the 159th and 160th Divisions of the 65th Army from the north, tightening the surrounding cordon from four directions. On October 6, Xue Yue ordered a counterattack, and by October 7 the Chinese army had effectively cut off all retreat routes. That evening, after fierce hand-to-hand combat, the 4th Army regained the hilltop, standing at a 100-meter-high position, and thwarted any Japanese plan to break through Baicha and sever Chinese retreat toward De'an. By October 8, Lieutenant Colonel Sakurada Ryozo, the 106th Division's staff officer, reported the division's deteriorating situation to headquarters. The telegram signaled the impending collapse of the 106th Division. On October 9, Kuomintang forces recaptured strategic positions such as Lishan, tightening encirclement to a small pocket of about three to four square kilometers in Nantianpu, Leimingguliu, and Panjia. That night, the vanguard attacked the Japanese 106th Division's headquarters at Leimingguliu, engaging in close combat with the Japanese. Matsuura and the division's staff then took up arms in defense. In the early hours of October 10, Japanese forces launched flares that illuminated only a narrow arc of movement, and a limited number of troops fled northwest toward Yangfang Street. The two and a half month battle inflicted tremendous casualties on the Japanese, particularly on the 101st and 106th divisions. These two formations began with a combined strength…

    3.172 Fall and Rise of China: Road to Wuhan Oct 20, 2025
    Show notes

    Last time we spoke about the flooding of the Yellow River. As Japanese forces pressed toward central China, Chiang Kai-shek weighed a desperate gamble: defend majestic Wuhan with costly sieges, or unleash a radical plan that would flood its heart. Across/Xuzhou, Taierzhuang, and the Yellow River's bend near Zhengzhou, commanders fought a brutal, grinding war. Chinese units, battered yet stubborn, executed strategic retreats and furious counteroffensives. But even as brave soldiers stalled the enemy, the longer fight threatened to drain a nation's will and leave millions unprotected. Then a striking idea surfaced: breach the dikes of the Yellow River at Huayuankou and flood central China to halt the Japanese advance. The plan was terrifying in its moral cost, yet it offered a temporary shield for Wuhan and time to regroup. Workers, farmers, soldiers, laborers—pushed aside fear and toiled through the night, water rising like a raging tide. The flood bought months, not victory. It punished civilians as much as it protected soldiers, leaving a nation to confront its own hard choices and the haunting question: was survival worth the price? #172 The Road to Wuhan Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

Following the Battle of Xuzhou and the breaching of the Yangtze dykes, Wuhan emerged as Japan's next military objective for political, economic, and strategic reasons. Wuhan served as the interim capital of the Kuomintang government, making it a crucial center of political authority. Its fall would deprive China of a vital rail and river hub, thereby further crippling the Chinese war effort. From a strategic perspective, Japanese control of a major rail and river junction on the Yangtze would enable westward expansion and provide a base for further advances into central and southern China. For these reasons, the Intelligence Division of the Army General Staff assessed that the capture of Wuhan would likely deliver the decisive blow needed to conclude the Second Sino-Japanese War. Recognizing Wuhan's strategic importance, both the National Revolutionary Army and the Imperial Japanese Army committed substantial forces to the city and its approaches. The IJA deployed roughly 400,000 troops, while the NRA fielded at least 800,000. China began the war with an estimated regular force of 1.7 to 2.2 million men, organized into six broad loyalty-based categories around Chiang Kai-shek's command. Directly loyal troops formed the first group, followed by a second tier of soldiers who had previously supported Chiang but were less tightly controlled. The next category consisted of provincial troops that Chiang could ordinarily influence, while a fourth group included provincial units over which his sway was weaker. The fifth category comprised Communist forces, the Eighth Route Army in the northwest and the New Fourth Army forming in the central Yangtze region. The final category consisted of Northeastern or Manchurian units loyal to Zhang Xueliang, known as the "Young Marshal." The first two categories together accounted for roughly 900,000 men, with about a million more in independent provincial armies, and roughly 300,000 in Communist and Manchurian forces. As commander-in-chief, Chiang could effectively command only about half of the mobilizable units at the outbreak of war in July 1937, which meant that military decisions were often slow, fraught with negotiation, and administratively cumbersome. Division-level coordination and communication proved particularly challenging, a stark contrast to the Japanese command structure, which remained clean and disciplined. Geographically, most of Chiang's loyal troops were located in the corridor between the Yangtze and the Yellow rivers at the start of 1938. Having participated heavily in the defense of Shanghai and Nanjing, they retreated to Wuhan at about half strength, with an already decimated officer corps. They then numbered around 400,000 and were commanded by generals Chen Cheng and Hu Zongnan. The northern regional armies, especially Han Fuju's forces in Shandong, had suffered severe losses; some units defected to the Japanese and later served as puppet troops. After six months of Japanese onslaught that cost the coastal and central regions—Peiping-Tianjin to Shanghai and inland toward Nanjing—much of the relatively autonomous, sizable armies remained from the southwest or northwest, under leaders such as Li Zongren, Bai Chongxi (Guangxi), Long Yun (Yunnan), and Yan Xishan (Shanxi and Suiyuan). Roughly 700,000 of these troops—predominantly from Guangxi under Li and Bai—were committed to the defense of Wuhan. The Communist forces, by contrast, numbered about 100,000 and remained relatively unscathed in bases north and east of Xi'an. In total, approximately 1.3 million men were under arms in defense of Wuhan. In December 1937, the Military Affairs Commission was established to determine Wuhan's defense strategy. Following the loss of Xuzhou, the National Revolutionary Army redeployed approximately 1.1 million troops across about 120 divisions. The commission organized the defense around three main fronts: the Dabie Mountains, Poyang Lake, and the Yangtze River, in response to an estimated 200,000 Japanese troops spread over 20 divisions of the Imperial Japanese Army. Li Zongren and Bai Chongxi, commanding the Fifth War Zone, were assigned to defend the north of the Yangtze, while Chen Cheng, commanding the Ninth War Zone, was tasked with defending the south. The First War Zone, situated to the west of the Zhengzhou–Xinyang segment of the Pinghan Railway, was responsible for halting Japanese forces advancing from the North China Plain, and the Third War Zone, located between Wuhu, Anqing, and Nanchang, was charged with protecting the Yuehan Railway. Following the Japanese occupation of Xuzhou in May 1938, they sought to expand the invasion. The IJA decided to dispatch a vanguard to occupy Anqing as a forward base for an assault on Wuhan. The main force would then advance north of the Dabie Mountains along the Huai River, with the objective of eventually capturing Wuhan via the Wusheng Pass. A second detachment would move west along the Yangtze. However, a flood from the Yellow River forced the IJA to abandon plans to advance along the Huai and instead to attack along both banks of the Yangtze. Despite Chinese numerical superiority on the Wuhan front, roughly a 2:1 advantage, the offensive faced several complicating factors. The NRA was a heterogeneous, fragmented force with a variety of tables of organization and equipment, and it lacked the unified command structure that characterized the IJA. Historian Richard Frank notes the broad diversity of Chinese forces at the outbreak of the war, which hindered cohesive mobile and strategic operations: "Chiang commanded armies of 2,029,000 troops of highly variegated capability and loyalty. His personal forces included an elite cadre of three hundred-thousand German-trained and eighty-thousand German armed men. A second stratum of the Chinese armies, numbering roughly 600,000 included various regional commands loyal to Chiang in the past that generally conformed to his directives. These troops were better armed and trained than the rest. The third category encompassed a million men who were neither loyal nor obedient to Chiang". The NRA faced a significant disadvantage in both quantity and quality of equipment compared to the Japanese. The disparity was stark in artillery allocations. An IJA infantry division possessed 48 field and mountain guns, whereas a German-equipped Chinese division had only 16. In terms of regiment and battalion guns, a Japanese division had 56, while a German-equipped Chinese division possessed just 30. Of roughly 200 Chinese infantry divisions in 1937, only 20 were German-equipped, and merely eight of those met their paper-strength standards. Many Chinese divisions had no artillery at all, and those that did often lacked radios or forward-observation capabilities to ensure accurate fire. These deficiencies placed the NRA at a clear disadvantage in firepower when facing the Japanese. These equipment gaps were compounded by poor training and tactical doctrine. The NRA lacked adequate training facilities and did not incorporate sufficient field maneuvers, gun handling, or marksmanship into its program. Although the 1935 drill manual introduced small-group "open order" tactics, many formations continued to fight in close-order formations. In an era when increased firepower rendered close-order tactics obsolete, such formations became a liability. The NRA's failure to adapt dispersed assault formations limited its tactical effectiveness. Defensively, the NRA also faced serious shortcomings. Units were often ordered to create deep positions near key lines of communication, but Chinese forces became overly dependent on fixed fortifications, which immobilized their defense. Poor intelligence on Japanese movements and a lack of mobile reserves, there were only about 3,000 military vehicles in China in 1937, meant that Japanese infantry could easily outflank fixed NRA positions. Moreover, the Japanese enjoyed superiority in artillery, enabling them to suppress these fixed positions more effectively. These realities left Chinese defenses vulnerable, especially in the war's first year. The leadership deficit within the NRA, reflected in limited officer training, further constrained operational effectiveness. Chiang Kai-shek reportedly warned that Chinese commanders often equaled their counterparts in rank but did not outmatch them in competence. Only 2,000 commanders and staff officers had received training by 1937, and many staff officers had no military training at all. Overall, about 29.1 percent of NRA officers had no military education, severely limiting professional development and command capability. With the exception of the Guangxi divisions, Chinese units were hampered by an unnecessarily complex command structure. Orders from Chiang Kai-shek needed to pass through six tiers before action could be taken, slowing decision-making and responsiveness. In addition, Chiang favored central army units under direct control with loyal commanders from the Whampoa clique when distributing equipment, a pattern that bred discord and insubordination across levels of the Chinese field forces. Beyond structural issues, the Chinese force organization suffered from a lack of coherence due to competing influences. The forces had been reorganized along German-inspired lines, creating large field armies arranged as "war zones," while Russian influence shaped strategic positioning through a division into "front" and "route" armies and separate rear-area service units. This mix yielded an incoherent force facing the Japanese. Troop placement and support procedures lacked rationalization: Chiang and his generals often sought to avoid decisive confrontation with Japan to minimize the risk of irreversible defeat, yet they also rejected a broad adoption of guerrilla warfare as a systematic tactic. The tendency to emphasize holding railway lines and other communications tied down the main fighting forces, around which the Japanese could maneuver more easily, reducing overall operational flexibility. Despite these deficiencies, NRA officers led roughly 800,000 Chinese troops deployed for the Battle of Wuhan. On the Wuhan approaches, four war zones were organized under capable if overextended leadership: 1st, 3rd, 5th, and 9th. The 5th War Zone, commanded by Li Zongren, defended north of the Yangtze to protect the Beijing–Wuhan railway. Chen Cheng's Ninth War Zone defended south of the Yangtze, aiming to prevent seizure of Jiujiang and other key cities on approaches to Wuhan. The 1st War Zone focused on stopping Japanese forces from the northern plains, while Gu Zhutong's 3rdWar Zone, deployed between Wuhu, Anqing, and Nanchang, defended the Yuehan railway and fortified the Yangtze River. Japan's Central China Expeditionary Army, commanded by Hata Shunroku, spearheaded the Wuhan advance. The CCEA consisted of two armies: the 2nd Army, which included several infantry divisions under Prince Naruhiko Higashikuni, and the 11th Army, advancing along the Yangtze's northern and southern banks under Okamura Yasuji. The 2nd Army aimed to push through the Dabie Mountains and sever Wuhan from the north, while the 11th Army would converge on Wuhan in a concentric operation to envelop the city. The Japanese forces were augmented by 120 ships from the 3rd Fleet of the Imperial Japanese Navy under Koshirō Oikawa, more than 500 aircraft from the Imperial Japanese Army Air Service, and five divisions from the Central China Area Army tasked with guarding Shanghai, Beijing, Hangzhou, and other key cities. These forces were intended to protect the back of the main Japanese thrust and complete the preparations for a major battle. The Kuomintang, led by Chiang Kai-shek, was acutely aware that Japan aimed to strike at Wuhan. Facing Japan's firepower and bold offensives, Chiang and his commanders pursued a strategy of attrition at the Wuchang conference in January 1938. Central China would be the primary theater of China's protracted struggle, distant from Japan's existing center of gravity in Manchuria. Chiang hoped Japan's manpower and resources would be exhausted as the empire pushed deeper into Central China. Eventually, Japan would be forced either to negotiate a settlement with China or to seek foreign assistance to obtain raw materials. The mountainous terrain to the north and south of the Yangtze presented natural obstacles that the Chinese believed would hinder large-scale concentration of Japanese forces. North of the Yangtze, the Dabie Mountains provided crucial flank protection; to the south, rugged, roadless terrain made expansive maneuvering difficult. In addition to these natural barriers, Chinese forces fortified the region with prepared, in-depth defenses, particularly in the mountains. The rugged terrain was expected to help hold back the Japanese offensive toward Wuhan and inflict substantial casualties on the attackers. The Yangtze itself was a critical defensive factor. Although the Chinese Navy was largely absent, they implemented several measures to impede amphibious operations. They constructed gun positions at key points where the river narrowed, notably around the strongholds at Madang and Tianjiazhen. Specialized units, such as the Riverine Defense Force, were deployed to defend these river fortifications against amphibious assaults. To reinforce the Riverine Defense Force, Chinese forces sank 79 ships in the Yangtze to create obstacles for potential Japanese naval advances. They also laid thousands of mines to constrain Japanese warships. These defensive measures were designed to slow the Japanese advance and complicate their logistics. The Chinese aimed to exploit stalled offensives to strike at exposed flanks and disrupted supply lines, leveraging terrain and fortified positions to offset Japan's superior firepower. On 18 February 1938, an Imperi…
