    Last time we spoke about the conquest of Angaur and the Japanese Triumph in China. By October 18th, the remaining Japanese on Angaur were compressed into a small area, and by the 21st, resistance had ceased. The Americans suffered 264 killed and 1,355 wounded, while approximately 1,300 Japanese were killed. Over in China, Hara's forces suffered heavy losses during a delaying action at Momauk, with troops joining Bhamo's defense by November 16. The 113th Regiment maneuvered to encircle Bhamo from the south, while the 114th Regiment approached from the north, creating a loose encirclement. The 22nd Division's movement prompted concerns of severing key rail lines, leading Japanese forces to reposition defensively. Despite intense fighting, including a strong Chinese offensive on November 19, the Japanese withdrew from key positions, allowing Chinese forces to capture Mangshi and secure a strategic airfield for resupply, significantly impacting the campaign's dynamics. This episode is the Formosa Air Battle Welcome to the Pacific War Podcast Week by Week, 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 you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. As we last saw on Peleliu, General Rupertus' 1st Marine Division, bolstered by Colonel Dark's 321st Regiment, successfully secured the island after approximately two weeks of intense fighting. However, Colonel Nakagawa's isolated and outnumbered garrison continued to resist in the Umurbrogol Pocket. As left by nature, the Umurbrogol Pocket was much like the Ibdi Pocket on Biak Island, but larger and rougher. Like Ibdi, the Umurbrogol originally had a thick cover of tropical trees and dense jungle undergrowth which, as the result of continued air, naval, and artillery bombardment (including extensive employment of aerial napalm strikes), was gradually knocked down or burned away. Again, as on Biak, the Japanese had improved upon nature. There were many artificial or semi-artificial caves which had been constructed to protect approaches to the inner sections of the pocket, and the Japanese had improved almost every natural cave. Where no caves were available or could be constructed, the defenders employed rock faults and crevices for defensive positions. Digging new entrances to existing caves or even cutting new levels within some caves, the Japanese were well prepared to execute a long and bloody holding action along the many ridges. These ridges, with the exception of the Five Sisters group at the southern side of the pocket, were generally parallel and oriented north-northeast to south-southwest. Steep-sided and fissured, many of them had razor-back summits upon which no cover could be found. The ridges were separated by deep draws, gullies, and wider valleys, the floors of which were strewn with coral boulders or coral outcroppings similar to stalagmites. Steep as they were, the sides of some ridges also were covered with such chunks and outcroppings. In late September, the exhausted infantrymen, who were tasked with containing the pocket while the Marines cleared northern Peleliu, made several heavy assaults. They only managed to reach the X-ray phase line, marking what was believed to be the northern edge of the core Japanese defenses, before being relieved by the 7th Marines. With Colonel Hanneken's 1st and 3rd Battalions now holding the X-ray line, Rupertus planned a strong attack southward while other Marine units maintained their positions on the western and southern sides of the pocket. On the morning of September 30, the attack was launched. However, fierce Japanese resistance, heavy rain, fog, and sickness hindered the 7th Marines' progress southward by October 2. On the following day, Hanneken's 2nd Battalion, supported by tanks, secured a foothold along the eastern side and top of Walt Ridge, while the 3rd Battalion finally captured the eastern slope of Boyd Ridge. By October 4, however, the 7th Marines had suffered such heavy losses and were so depleted that Rupertus was left with no choice but to relieve them as well. As a result, Colonel Harris’s 5th Marines were once again thrust into action. On October 7, following an hour-long artillery and mortar barrage, the 3rd Battalion, along with six tanks, advanced into Mortimer Valley. However, Nakagawa’s determined defenders continued to resist fiercely, successfully repelling two powerful tank-infantry assaults, causing heavy American casualties. Our old friend Eugene Sledge with K Company, 3d Battalion, 5th Marines, wrote about fighting in this area, it is as follows “Johnny led us on up through a jumble of rocks on Hill 140. Company K's line was emplaced along a rock rim, and we set up the mortars in a shallow depression about twenty yards behind it. The riflemen and machine gunners in front of us were in among rocks along the rim of Hill 140 facing east toward Walt Ridge and the northern end of the infamous Horseshoe. We had previously attacked that valley from its southern end. From the rim of Hill 140 the rock contours dropped away in a sheer cliff to a canyon below. No one could raise his head above the rim rock without immediately drawing heavy rifle and machine-gun fire. The fighting around the pocket was as deadly as ever, but of a different type from the early days of the campaign. The Japanese fired few artillery or mortar barrages, just a few rounds at a time when assured of inflicting maximum casualties. That they usually did, and then secured the guns to escape detection. Sometimes there was an eerie quiet. We knew they were everywhere in the caves and pillboxes. But there was no firing in our area, only the sound of firing elsewhere. The silence added an element of unreality to the valleys. If we moved past a certain point, the Japanese opened up suddenly with rifle, machine-gun, mortar, and artillery fire. It was like a sudden storm breaking. More often than not we had to pull back, and not a man in the company had seen a live enemy anywhere. They couldn't hope to drive us off by then or to be reinforced themselves. From that point onward, they killed solely for the sake of killing, without hope and without higher purpose. We were fighting in Peleliu's ridges and valleys, in terrain the likes of which most Americans could not even visualize, against an enemy unlike anything most Americans could imagine”. In response to this setback, Rupertus halted further offensive operations and ordered his forces to maintain pressure on the Japanese stronghold through sustained artillery fire and aerial bombardments. Over the next two days, this relentless bombardment cleared so much foliage and undergrowth that visibility across the ridges improved significantly. This allowed the attacks to resume on October 9, and although no ground was gained initially, Harris’s 2nd Battalion succeeded in securing Wattie, Baldy, and 120 Ridges on October 10. They then pushed south to capture the tactically vital Hill 140. From this position, a Marine howitzer provided critical support to the 5th and 7th Marines as they cleared an area approximately 700 yards long and up to 200 yards east beyond the previous containment lines along West Road. However, on October 14, Dark’s 321st Regiment began moving up to relieve the Marines, as General Geiger had decided to end Marine participation in the Battle of Peleliu. Just before they were relieved, Eugene Sledge wrote a passage about moving through positions in October, finding numerous dead, stinking in the hot sun. One corpse he found made a significant impact on him, here is the passage. “As we moved past the defilade, my buddy groaned, “Jesus!” I took a quick glance into the depression and recoiled in revulsion and pity at what I saw. The bodies were badly decomposed and nearly blackened by exposure. This was to be expected of the dead in the tropics, but these Marines had been mutilated hideously by the enemy. One man had been decapitated. His head lay on his chest; his hands had been severed from his wrists and also lay on his chest near his chin. In disbelief I stared at the face as I realized that the Japanese had cut off the dead Marine's penis and stuffed it into his mouth. The corpse next to him had been treated similarly. The third had been butchered, chopped up like a carcass torn by some predatory animal. My emotions solidified into rage and a hatred for the Japanese beyond anything I ever had experienced. From that moment on I never felt the least pity or compassion for them no matter what the circumstances. My comrades would field-strip their packs and pockets for souvenirs and take gold teeth, but I never saw a Marine commit the kind of barbaric mutilation the Japanese committed if they had access to our dead. When we got back to the gun pit, my buddy said, “Sledgehammer, did you see what the Nips did to them bodies? Did you see what them poor guys had in their mouths?” I nodded as he continued, “Christ, I hate them slant-eyed bastards!” “Me too. They're mean as hell,” was all I could say.” About mid-October, a number of command changes occurred in the Palaus area. On the 12th, for instance, the 1st Marine Division was relieved of all responsibilities other than continuing the fight in the Umurbrogol Pocket. The 321st Infantry took over the defenses along the eastern arm, while the Island Garrison Force assumed responsibility for the area south of the pocket. On the morning of October 12, the command post of the 3rd Amphibious Corps moved ashore and General Geiger, the corps commander, declared that the assault and occupation phase of operations on Peleliu was ended. The exact meaning of this announcement is not clear, especially in relation to Admiral Fort's somewhat similar declaration of September 30, stating that Angaur, Peleliu, Ngesebus, and Kongauru had been captured and occupied. However, General Geiger's announcement seems to have been made in preparation for the 1st Marine Division's imminent departure from the Palaus. The statement also bears relation to the passing of control of operations in the Palaus from the 3rd Fleet and Admiral Halsey (as then represented by Admiral Fort's Western Attack Force headquarters) to the Headquarters, Forward Area Central Pacific (Task Force 57), under Admiral Hoover. On the 13th General Geiger issued orders alerting the 321st Regimental Combat Team to relieve the 1st Marine Division elements still at the Umurbrogol Pocket. The next day, control over all operations in the Palaus passed from Admiral Fort to Admiral Hoover's command. With the relief of the Marines at the Umurbrogol, the remainder of the battered 1st Marine Division then began preparations for leaving the Palaus. At the same time, the 1st Battalion, 323rd Regiment, fresh from operations at Ulithi Atoll, started preparations to relieve Marine units in the southwest corner of the pocket, with the rest of the regiment to follow. Consequently, the Marines prepared to depart from the Palaus, with Dark taking over responsibility for the reduction of Umurbrogol. Since September 29, the Marines had endured an additional 1,000 casualties, bringing their total to 1,252 killed and 5,274 wounded. In return, they estimated having killed between 850 and 1,000 Japanese soldiers, leaving roughly 1,000 defenders in the shrinking pocket as the 321st moved back in. After a failed local attempt to capture the northernmost peak of the Five Brothers Ridge on October 16, Dark launched a general attack the next day, which resulted in a modest gain of about 125 yards and the neutralization of some caves to the east. On the morning of October 18, the attack resumed, with Dark’s 2nd Battalion successfully capturing three peaks of the Five Brothers, thanks to support from mortars, tanks, and LVT-mounted flamethrowers. However, undeterred by this overwhelming firepower, the Japanese immediately counterattacked and reclaimed the three peaks by nightfall. On the southwest side of the pocket, Nakagawa had also sent infiltrators through tunnels and connecting caves to raid the enemy lines, forcing Geiger to redirect elements of the 7th Marines and 323rd Regiment to address this new southern pocket. After much effort, most of the infiltrators were finally pushed north on October 23, though mopping up in the Southern Pocket wasn't completed until November 3. Meanwhile, on October 19, following a deadly napalm strike, Dark’s 1st Battalion advanced up to 50 yards along the ridges west of Hill 140 with the help of howitzers and much-needed sandbags. The battalion's men, lying prone on the ground, inched their sandbags forward with rifle butts or sticks, laboriously expanding their hold and almost realizing the infantrymen's dream of portable foxholes. The next day, General Mueller formally assumed command of the Peleliu campaign. Following some reconnaissance and a napalm strike, the 321st resumed its assault on October 21, making significant progress by advancing over 100 yards and capturing the northernmost peak of the Five Brothers. On the subsequent day, Dark launched a coordinated attack with his 2nd Battalion securing the first three Brothers, the reinforced 1st Battalion struggling to breach Death Valley, and the 3rd Battalion sweeping through Mortimer Valley with tank support. After this achievement, while Colonel Watson was bringing the remaining 323rd Regiment to the Umurbrogol area, the only major progress was the capture of the fourth Brother on October 23. Two days later, the 323rd began relieving the weary 321st Regiment. By this time, Dark had lost 146 men killed and 469 wounded on Peleliu. As Watson took over, Nakagawa's forces had been reduced to about 700 effective troops, including those lightly wounded. The pocket's dimensions had also been compressed to an average north-south length of about 600 yards. Fortunately for the defenders, heavy rains, fog, and poor visibility significantly hampered Watson’s operations in the Umurbrogol Pocket from October 26 to November 1. This period was used mainly for mortar barrages, napalm strikes, defense enhancements, and extending sandbag fortifications. Despite this pause, Nakagawa launched near-nightly counterattacks over the six days, primarily targeting the Five Brothers, which mostly resulted in further casualties for the defenders. To understand the eventual reduction of the Umurbrogol Pocket, we will need to shift our focus to the plans and preparations for General MacArthur's grand return to the Philippines. Previously, General MacArthur, along with Admirals Nimitz and Halsey, decided to abandon the preliminary operations for Mindanao and Yap in favor of a direct assault on Leyte. To be much more frank General MacArthur was having a turf war with Admiral Nimitz. After the Marianas campaign, the endgame of Nimitz island hoping across the Pacific forced the Joint Chiefs of staff to make a choice, to invade the Philippines, or leave it to wither on the vine and instead invade formosa. Admiral King, the joint chiefs of staff, Admiral Leahy and General Hap Arnold all favored the Formosa option. For quite awhile Nimitz got everyone onboard with this plan as Formosa was a logical choice being only 900 kms away from Japan and its seizure would cut off southeast asia…

    Last time we spoke about the ongoing battles of Peleliu, Angular and Operation Ichi-Go. On September 23, Colonel Venable's regiment struggled to breach Lake Salome's defenses, leading to tactical changes and propaganda attempts to force Japanese surrender, which ultimately failed. The American command underestimated Japanese resolve, resulting in heavy bombardments and a strategic advance. By September 26, American forces had divided Peleliu and isolated Japanese defenders, facing fierce resistance but making significant progress. On September 27, 1944, Company F secured two ridges in Peleliu but struggled with Japanese forces entrenched in caves, halting progress. Despite controlling the northern shore, Marines faced persistent underground resistance from skilled Japanese miners. Meanwhile, the 5th Marines captured Hill 3, Ngesebus Island, and Radar Hill. In October, Japanese offensives continued against minimal resistance. This episode is the Japanese Triumph in China Welcome to the Pacific War Podcast Week by Week, 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 you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. In our previous episode, General Mueller’s infantry on Angaur had driven Major Goto’s isolated forces into the Romauldo Pocket by October 1. After this victory, it was decided to shift away from costly full-scale infantry assaults. Instead, tanks, mortars, and artillery were deployed to target the remaining enemy positions directly. On 6 October artillery and mortars undertook an especially heavy bombardment. From 0700 to 1030, 155-mm. howitzers fired at especially chosen targets, including a suspected Japanese observation post, while 105-mm. howitzers, 4.2-inch mortars, 81-mm. mortars, and 60-mm. mortars laid concentrations on the flanks and rear of the remaining Japanese-held area to prevent any Japanese from escaping. At 1030 the artillery and mortars switched to smoke shells to blanket the Japanese area and at 1035 these weapons ceased fire. Following the bombardment, two companies were dispatched to feint attacks on the Japanese flanks, aiming to force them out of their fortified positions. The defenders, deceived by the ruse, were then subjected to another intense artillery and mortar barrage, which inflicted significant casualties. Additionally, in the afternoon, a major concrete and steel emplacement, likely serving as Goto's command post, was uncovered and destroyed by direct fire. With the enemy defenses considerably weakened, infantry operations resumed, focusing on sniper teams, small patrols, ambushes, and booby traps to encircle the remaining Japanese forces and cut off their supply and escape routes. Over the next few days, the Americans also rescued 183 captive natives during the final stages of their assault. The Japanese had under their control in the final pocket a number of Angaur natives, three of whom had managed to make their way into the 322nd Regiment lines after a surrender broadcast on October 1. These related stories of hardships suffered in caves where the Japanese had kept them closely guarded and also told the 322nd that more natives were being held in the northwest pocket. First attempts by native volunteers to lead some of the others out were unsuccessful; but on October 8,137 more natives made their way out of the pocket to an area where elements of Company B, 306th Engineers, were working. The next day, three native volunteers led 90 more out of the pocket. About 1/5 of the total of 183 natives rescued from the Japanese needed extensive medical attention and all the rest were suffering from malnutrition. The healthier ones rebuilt their own village and some were ultimately used as labor on various projects at Angaur. On October 13, a coordinated attack was launched, with the 1st Battalion advancing from the west and the 2nd Battalion pushing from the north and northeast. Despite fierce resistance, by October 18 the Americans had successfully compressed the remaining Japanese into a pocket approximately 100 yards long and 50 yards wide. The following night, Major Goto was killed, and by October 21, the last pockets of resistance were eliminated. The engagement ended two days later when the Americans realized they had eliminated nearly all the Japanese troops, with only a few stragglers remaining. By the conclusion of the Battle of Angaur, approximately 1,300 Japanese soldiers had been killed, and 45 were captured. The Americans, on the other hand, suffered 264 men killed and 1,355 wounded, primarily from the 322nd Regiment. To be more specific the 321st Infantry's part in the operation had cost that regiment 26 men killed and 135 wounded. The 322d Infantry, which fought longer and against stiffer opposition, lost 211 men killed and 772 wounded. Despite the heavy losses, capturing Angaur proved crucial in securing the Palaus and removing the island group as a threat to Allied lines of communication across the western Pacific toward the Philippines. Airdrome construction on Angaur was begun on 20 September, F plus 3, by the 1884th and 1887th Engineer Aviation Battalions. The first plane, a C-47, landed on the field on F plus 28, 15 October. Four days later two 6,000-foot landing strips were completed and work on taxiways, gasoline storage, and other air-base installations was well along. Air-base construction on Angaur presented difficult problems. There was available no conveniently located Japanese airfield which the Allies could repair, improve, and expand. Instead, the work had to begin at the beginning. Jungle had to be cut away, swamps filled, and rough terrain leveled. There was no hope that an airstrip could be prepared in three or four days as had been the case on many other islands in the Pacific. The completion of two 6,000-foot runways by 19 October, F plus 32, represented a considerable accomplishment. In defending Angaur, the Japanese lost a well-equipped, highly trained, and well-led infantry battalion. While this force might have been more effectively deployed elsewhere in the Palaus, it succeeded in its mission of delaying the American advance. Meanwhile, General Ishii of the 32nd Division decided to reinforce the limited Japanese presence in Morotai to hinder the development of an enemy airbase capable of supporting an assault on the Philippines. Consequently, three temporary raiding detachments from the 10th Expeditionary Unit and the 211th and 212th Regiments were formed, with the 210th Regiment preparing a battalion as a follow-up force. On the night of September 26, Ishii’s reinforcements began their movement to Morotai in barges, with two detachments successfully landing near Tilai and the other near Cape Posiposi despite interference from Allied PT boats. Enemy patrols around the island's perimeter blocked the use of coastal tracks, forcing the reinforcements to navigate through dense jungle. As the concealed Japanese raiders made their way toward Major Kawashima’s main force in the Pilowo-Sabatai River area, the 3rd Battalion of the 210th Regiment landed in the Boesoboeso sector on October 9. The raiding detachments finally joined up with the 2nd Provisional Raiding Unit on October 20. Without waiting for the 210th battalion, Kawashima initiated a series of new infiltration raids, some of which reached the airfield itself. Although these reinforcements created some disruptions by harassing Allied outposts, they did not significantly impact the situation at Morotai. This was due to high disease rates among the reinforcements and the inability to deliver enough supplies through the Allied air and naval blockade. General Anami decided more decisive action was needed to prevent the enemy from utilizing their airbase effectively. He instructed Ishii to deploy as much force as possible to Morotai to destroy the enemy. In response, Ishii planned to send additional reinforcements, including the main forces of the 210th and 211th Regiments and the 18th Shipping Engineers. By November 16, approximately 1,900 troops successfully landed south of Wadjaboela, with Colonel Kisou Ouchi taking command of all Japanese forces on Morotai. Raiding activities intensified in December, but with the new year, American torpedo boats further tightened the blockade, making it impossible for the 32nd Division to supply the ammunition and rations needed for a major offensive. Unable to dislodge the enemy from Morotai, the Japanese eventually had to withdraw to the center of the island, where they remained until the end of the war. The most notable Japanese response to the Allied landing was a series of frequent but mostly ineffective air raids. The first raid occurred on September 16 when a solitary enemy aircraft dropped three bombs on the Red Beach area, causing no damage. Between September 15, 1944, and February 1, 1945, General Sudo’s 7th Air Division conducted 82 raids on Morotai, involving 179 sorties. The initial 54 raids caused minimal damage, with only twelve Allied soldiers wounded by October 4. However, the later raids resulted in 42 Allied aircraft destroyed, 33 damaged, 19 men killed, and 99 wounded. Despite these efforts, Morotai was successfully developed into a crucial base for the return to the Philippines. In Bougainville, with General Griswold’s 14th Corps initially slated for the Leyte invasion, efforts were made to replace it with the Australian 2nd Corps. Although Griswold’s corps would not participate in the October 20 operation, advance elements of General Savige’s headquarters landed on October 6 to facilitate the transition. By mid-November, the 7th Brigade had relieved the 129th and 145th Regiments, and on November 22, Savige officially took command of Allied operations on Bougainville. By December 12, the replacement of American frontline troops by Australians was complete, and with only a few service personnel remaining, all American troops had departed by February 1, 1945. Despite having 30,000 men—though always short on heavy equipment and shipping—Savige's forces were considered sufficient to continue monitoring the Japanese and defending the perimeter around the airfields from any potential counterattacks. However, General Blamey disagreed with this approach and preferred a more aggressive strategy. He wanted his troops to actively seek out and destroy the enemy by patrolling deep into Japanese-held territory, targeting supply areas and bases to starve and eventually annihilate the Japanese garrisons. This shift in strategy signaled the start of a new offensive phase in the Bougainville Campaign. At the same time, attention shifts to North Burma, where the Allied campaign continued after the victories at Myitkyina and Mogaung. However, the strained relationship between General Stilwell and Chiang Kai-Shek was approaching its breaking point. Confronted with the impending loss of Guilin, Stilwell persuaded President Roosevelt to issue an ultimatum to Chiang, threatening to cut off American aid to China unless Stilwell was given full command of all forces in China. Chiang, perceiving this as an attempt to dominate China, countered by demanding Stilwell's immediate replacement and welcoming any other qualified American general. As a result, on October 19, Stilwell was recalled and replaced by Major-General Albert Wedemeyer by the end of the month. The China-Burma-India Theater was then reorganized: Lieutenant-General Daniel Sultan took over the India-Burma Theater, while Wedemeyer assumed command of the newly established China Theater. However, Wedemeyer would only serve as chief of staff to Chiang, not taking effective command of the Chinese forces. Thus, no American officer would be held accountable for the loss of eastern China. Nonetheless, this represented another significant diplomatic victory for Chiang Kai-Shek, though it would be his last for many years. However, it also marked the end of his relationship with Roosevelt, who had previously championed China's and the Generalissimo's interests. Meanwhile, upon taking command, Wedemeyer faced open dissent among the Chinese Nationalists, with local commanders in eastern China on the verge of insurrection against Chiang’s regime, as he had refused to supply arms to those defending against the Japanese advance in Operation Ichi-Go. There were many detailed reports that the east China commanders bitterly resented the Generalissimo's failure to support them. When Hengyang fell on August 8, Chinese claiming to be emissaries of these men presented to American authority a plan for a separatist regime and pleaded for American support. Unknown to the Americans, Chinese making identical representations had been negotiating with the Japanese since the winter of 1943-44. Intelligence reports were received at US headquarters to the effect that the Generalissimo's attitude toward the east China campaign reflected an understanding between him and the Japanese under which they would leave him undisturbed in southwest China if he in turn would not interfere while they took the airfields that presented so obvious a menace to the Japanese homeland. In 1951 a group of senior Japanese staff officers of China Expeditionary Army were interrogated on the question of Sino-Japanese relations in 1944. They denied that there had been any understanding between the Japanese and the Chinese Central Government. Two of them, Lt. Cols. Yoshimasa Okada and Yoshio Fukuyama, stated that an agreement was reached between the Japanese 23rd Army at Canton and the local Chinese commander, General Yu Hanmou, in February 1944 under which General Yu agreed not to disturb Canton when the Japanese marched north from it. Yu kept his word, according to Okada, even though the Generalissimo was ordering him to attack Canton. The Japanese officers agreed among themselves that there had been extensive contact with dissident Nationalist commanders in southeast China, and stated that through many channels they had sought to inform the Chinese that the east China drive offered no threat to them, but only to the US airfields. One of Wedemeyer’s key objectives was to prevent China from fragmenting into warring factions. Additionally, he observed that air transport was delivering supplies to China at unprecedented rates, with 35,131 tons arriving in October 1944—four times the amount sent to support Stilwell in October 1943. The strength of the Allied forces in northern Burma and the weakened state of the Japanese meant that time was on Wedemeyer’s side; each day China remained an active belligerent bolstered the prospect of significant American supplies soon being available. Consequently, his mission involved continuing support for General Chennault’s 14th Air Force, General LeMay’s 20th Bomber Command, and air transport over the Hump; further training and advising the Y-Force in Yunnan and the Z-Force in eastern China; and assisting the Generalissimo with military operations against the Japanese. Speaking of Chennault's 14th air force, by November 1944, they now had an average strength of 398 fighters, 97 medium bombers, and 47 heavy bombers. In that same month the Fourteenth received 13,578 tons of supplies flown in over the Hump, of which 9,357 tons were gas and oil. From the Kunming airfields, the China Wing of the ATC flew these supplies to Chenn…

    Last time we spoke about the battles for Peleliu and Angaur. Following the amphibious assaults on Peleliu and Anguar, US Marines under General Rupertus intensified their offensive. On September 17, Colonel Hanneken’s 7th Marines advanced in Peleliu's southern sector, as the 1st and 5th Marines pushed north, confronting the fortified Umurbrogol Mountains, where Colonel Nakagawa’s defenses stalled their progress. Despite reaching key positions by mid-morning, intense Japanese counterattacks continued, causing heavy casualties. On September 18, the 7th Marines, aided by armor, resumed their slow advance, securing the southern part of Peleliu by day's end. Meanwhile, the 1st and 5th Marines faced brutal combat in the central ridges, suffering significant losses. By September 21, the capture of nearby Ulithi Atoll provided a strategic base for future operations. Despite securing important positions, the Marines encountered severe resistance in the Umurbrogol Mountains, leading to high casualties and necessitating reinforcements. By September 23, the Americans secured footholds on Peleliu and Anguar, yet fierce fighting persisted in Nakagawa’s fortified positions.

This week we are picking up back over on Peleliu and Anguar where the Japanese are still providing stiff resistance. On September 23, Colonel Venable’s 322nd Regiment had made little progress breaking into the Lake Salome bowl. With their commanding officer severely injured, a change in tactics was imminent. On the morning of September 24, propaganda broadcasts over a public address system were used to try and persuade the remaining Japanese to surrender. However, only two Japanese soldiers surrendered, reporting that over 300 defenders remained in the bowl under Major Goto. This accurate estimate was disregarded by the American command, who believed only about 150 defenders remained. Following this failed attempt, all available artillery bombarded the bowl in preparation for an attack from the north, altering the appearance of the bowl's interior and rims to aid the upcoming assault. Back at Peleliu, after heavy bombardment, Colonel Dark’s 321st Regiment resumed its advance north along the coast on September 24, despite continued harassment from Japanese fire from the central ridges. By noon, they had secured the trail-road junction south of Garekoru. Some troops explored the trail to the east, encountering heavy resistance, while Company G advanced rapidly north through Garekoru, reaching the O-4 Line. Behind them, Dark’s 3rd Battalion and Colonel Hanneken’s 3rd Battalion also pushed northwards. Further east, the 7th Marines pressed against Colonel Nakagawa’s main defenses on the Umurbrogol Mountains. By nightfall, having successfully resisted Japanese counterattacks on O-4, General Rupertus’ northward drive had proven to be a significant success. He next planned to cut across the island on September 25 through the eastern trail to completely isolate the Japanese forces in the Umurbrogol ridges. At 07:00, Dark’s troops began moving eastward, with Company E successfully reaching the edge of East Road against light opposition. They halted in front of Hill B, which dominated the eastern area. However, the 3rd Battalion encountered heavier resistance from pillboxes and emplacements protected by steep walls and sheer cliffs guarding the northern approaches to the Umurbrogol defense system, making little progress. Meanwhile, to the north, a strong tank-infantry patrol advanced about 1,200 yards, killing 30 Japanese and destroying four pillboxes and two large supply dumps before reaching the O-5 Line. The weak resistance encountered by the patrol suggested that remaining Japanese strength was concentrated in the Umurbrogol Pocket. Thus, at 10:30, Rupertus decided to commit the 5th Marines for a drive to the northern tip of Peleliu. Rapidly relieved by the 1st Marines on eastern Peleliu. Orders to move to the western portion of Peleliu found the 5th Marines in static positions on Eastern Peleliu, where the regimental mission had been to prevent enemy counterlandings. The 1st Battalion was deployed in the vicinity of the radio direction finding station near Ngardololok, the 2d Battalion was holding the islands north of the northeastern peninsula, while the 3d Battalion, less one company, occupied defensive positions along Purple Beach. The 1st Marines completed the relief of the 5th shortly after noon and assumed command of the 5th Marines sector at that time. In order to expedite movement of the regiment to the West Road, the battalions moved out on trucks at 1300, with 1/5 in the lead, followed by 3/5 and 2/5. By 1600, the 5th Marines had executed the passage of the lines, and the regiment passed through Phase Line O-4 near Garekoru. As 1/5 continued its advance up the West Road, it encountered erratic resistance from what appeared to be Japanese holdouts. The level terrain was devoid of the dense jungle growth abounding elsewhere on Peleliu and offered ideal conditions for the movement of tanks and LVT flamethrowers accompanying the advance battalion. Aside from occasional Japanese sniper and mortar fire, the advance continued for about 500 yards without interruption to Road Junction 15, where the West and East Roads met. This vital point was defended by a small Japanese force, which had installed itself on a ridge dominating the road forks. Around 1700, as the Marines approached this point, the enemy opened fire, which served only to delay the Marines. When the firefight ended the Japanese had lost 20 killed. The battalion continued its advance for another 100 yards and seized the Japanese radio station, whose towers the forward elements of RCT 321 had spotted on the previous day. Having secured this objective, the battalion established night defenses north of the radio station from the beach to the high ground east of the West Road. Upon reaching Road Junction 15 in the wake of the advance of 1/5, the 3d Battalion pivoted to the southeast and headed down East Road, where it established night defenses on the road and along the western slopes of Hill 80. The latter hill, in itself an isolated terrain feature, owed its importance to its location, for it was the only link separating the Kamilianlul ridges to the south from the Amiangal ridges, which formed the northernmost hill mass on Peleliu. Throughout the evening and night, the forward elements at the radio station were continuously and heavily attacked and bombed but managed to hold against the enemy onslaught. Meanwhile, at Angaur, after a heavy and prolonged artillery bombardment, the 3rd Battalion, 322nd Regiment pushed forward to launch its assault from the north. Finding no route south over the cliffs, they assembled near the northern end of the Milwaukee Railroad for an attack west the following day. At 07:30 on September 26, the infantry launched their assault on Lake Salome, quickly taking control of the eastern rim with minimal resistance. Facing increasing enemy fire, the Americans made their way down the eastern rim to the bowl floor. However, by the end of the day, they were halted by Goto’s positions on the northern cliffs and "The Island," a gap between an overgrown coral mound and the eastern rim. To the south, the 2nd Battalion supported the attack by advancing north, capturing the southeast rim and clearing out several enemy cave positions. Back over on Peleliu the Marines had a very rough night full of Japanese infiltrator harassment. In fact our old friend Eugene Sledge wrote about the night of September 25th and what his unit of K Company, 3rd battalion, 5th marines went through. The Japanese who had come across the road in front of me were probably members of what the enemy called a “close-quarter combat unit.” The enemy soldier shot by Sam was not dressed or equipped like their typical infantryman. Rather he wore only tropical khaki shorts, short-sleeved shirt, and tabi footwear (splittoed, rubber-soled canvas shoes). He carried only his bayonet. Why he entered our line where he did may have been pure accident, or he may have had an eye on our mortar. His comrade angled off toward the right near a machine gun on our flank. Mortars and machine guns were favorite targets for infiltrators on the front lines. To the rear, they went after heavy mortars, communications, and artillery. Before Company K moved out, I went down the road to the next company to see what had happened during the night. I learned that those blood-chilling screams had come from the Japanese I had seen run to the right. He had jumped into a foxhole where he met an alert Marine. In the ensuing struggle each had lost his weapon. The desperate Marine had jammed his forefinger into his enemy's eye socket and killed him. Such was the physical horror and brutish reality of war for us. The 1/5 spent the early hours of 26 September in consolidating its positions around the radio station and preparing for continuation of its attack later in the day to the northern tip of Peleliu. Shortly after 0600, 3/5 jumped off for an attack against Hill 80 with Company K on the left and Company I on the right. The attack carried the hill and by 0830 the assault force reached a swamp bordering the east coast of Peleliu. This advance of the 3d Battalion was of major importance because it effectively cut the island in two. Late in the afternoon most of the battalion moved back from Hill 80 to a reserve position near the junction of East and West Roads. The unit's southern flank extended south from the junction along East Road to Hill 80, where Company I was stationed for the night. Between Company I, 5th Marines, and the 2d Battalion, 321st Infantry, at Hill B, lay a gap approximately 1,800 yards long through which only the 321st Infantry's Neal Task Force had passed. In this gap lay 1,500-yard-long Kamilianlul Mountain, held by an unknown number of Japanese and as yet not even reconnoitered by American units. The 5th Marines consolidated their positions and resumed their assault. The 1st Battalion, 5th Marines, ran into stiff opposition from the Amiangal ridges dominating northern Peleliu. The northern portion of the L-shaped hill system consisted of ridges running generally from northeast to southwest for about 1,000 yards; the southern leg extended from northwest to southeast. The southern leg of the ridges was not continuous but broken into four separate hills or knobs, designated from northwest to southeast as Hill 1, Hill 2, Hill 3, and Radar Hill, so named because it had at one time served as an enemy radar installation. These four knobs were to gain ill repute as Hill Row. The entire Amiangal ridge system was held in strength by the Japanese, particularly the portion paralleling the route of advance of 1/5. This part contained some of the most elaborate caves and tunnels on Peleliu. The battalion had barely started out along the West Road when the enemy in and on Hill 1 opened up on the Marines with 37mm and 75mm guns as well as automatic weapons and mortars. This curtain of fire from the Amiangal ridges was reinforced by heavy fire from Ngesebus Island. All forward movement soon halted. Attacking eastward from the West Road, Company B assaulted the second knob, Hill 2, but also encountered opposition. Through sheer determination the company was able to gain a firm foothold on the hill by early afternoon. This accomplishment in effect served to outflank the Japanese on Hill 1, but Japanese resistance on the last mentioned hill continued throughout the day. An attempt by Company C to seize all of Hill 1 during the remaining hours of daylight was unsuccessful, and continuation of the assault had to await the following day. During the bitter fighting in which 1/5 engaged during the night of 25-26 September and for most of the following day, 2/5 remained stationary on the southern flank of the regiment. At 1600 on 26 September, when it had become apparent that 1/5 could make no further progress, 2/5 was ordered to attack. The battalion advanced northward through the left wing of 1/5, carefully bypassing embattled Hill 1. In the course of its advance, the battalion drew heavy fire from Japanese emplacements in the plain, from the ridges on its right, as well as from Ngesebus. Enemy mortars proved especially troublesome. As a result of the heavy fire, Company F lost four of its supporting tanks before it had advanced very far beyond Hill 1. Attempts by the artillery to give all possible support to the battalion were largely ineffectual. "We fired frequent missions throughout the day on these mortars; the reported effect was that the mortars were neutralized while we fired but that they were not destroyed. The enemy apparently withdrew into the caves during the period of our fire." As evening approached, the 5th Marines occupied a jagged front line. The 1st Battalion, though out of contact with the 2d, was tied in with the 3d on the right. The mission of the 3d Battalion was to support either the 1st or 2d Battalion in the event of a major Japanese counterattack. Further progress of the 2d Battalion was impeded by a large antitank ditch, which blocked the approach to the remnants of the Peleliu phosphate plant. The Japanese had converted the reinforced concrete foundation of the otherwise demolished structure into a major defensive installation. Exposed to the enemy fire from Ngesebus Island and plunging fire from caves and defensive positions from the hills, 2/5 found itself in a very unenviable situation. Further south, after some necessary adjustments, Dark’s forces assaulted Hill B with two battalions. Initially repelled, Dark then sent a task force led by Captain George Neal to attack from the north. After a complex maneuver north and then south, the Neal Task Force attacked Hill B just as other elements of the 321st fought their way to the top through challenging terrain. The hill eventually fell to the Americans, completing the isolation of the Umurbrogol Pocket. By the end of the day, the island was divided in two places, leaving Nakagawa’s determined defenders isolated in two major pockets. On September 27, with the Umurbrogol Pocket now contained, the 5th Marines continued their operations against Amiangal Mountain. At the same time, the 1st Battalion, 321st Regiment advanced north from the Hill B area to close the long gap along East Road up to Hill 80. Dark's infantrymen secured Kamilianlul Mountain with minimal resistance and then moved towards the Marines’ road junction. The 2d Battalion was to find progress extremely rough for the remainder of the day. First, the erstwhile phosphate plant, which the Japanese had turned into a blockhouse, had to be secured in an area that bristled with snipers. The problem confronting Colonel Harris was a formidable one. The blockhouse in front of 2/5 could not be taken until the antitank ditch blocking the approaches to it had been seized. This was a job that the infantry could not tackle without armored support. The regimental commander decided to utilize all arms available in reducing these obstacles. First of a…

    Last time we spoke about the invasion of the Palau Islands. General Rupertus’s 1st Marine Division was tasked with attacking Peleliu, while General Mueller’s 81st Division would land on Angaur. Prior to the landings, extensive neutralization of Japanese airfields was carried out by Allied forces. On September 6, carrier-based aircraft attacked the Palaus, significantly damaging enemy targets but encountering minimal resistance. The invasion fleet, led by Admiral Fort, began landing operations on September 15. Despite strong Japanese defenses, especially around Peleliu’s rugged coral ridges, the Marines made some progress but faced intense resistance. Notable figures such as Eugene Sledge, author of “With the Old Breed,” provided personal insights into the brutal conditions faced. The landing saw heavy casualties and challenges, including ineffective pre-landing bombardments and fierce counterattacks, but the Marines managed to secure key positions by the end of the first day. The 81st Division then proceeded with landings on Angaur on September 17, facing lighter resistance but difficult terrain. This episode is the Battles of Peleliu and Angaur Welcome to the Pacific War Podcast Week by Week, 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 world war two?

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. Last time we left off, Peleliu and Anguar had just been amphibiously assaulted by US Marines. While the landings on Angaur were underway, General Rupertus pressed on with the Peleliu offensive on September 17. In the southern sector, Colonel Hanneken’s 7th Marines made headway against the isolated Japanese defenders. The 3rd Battalion cleared a minefield and captured the southeast promontory, while the 1st Battalion took on the southwestern promontory but only managed to secure half of it due to fierce enemy resistance. To the north, the 1st and 5th Marines advanced further, encountering the Umurbrogol Mountains for the first time, where Colonel Nakagawa had fortified his defenses. On the left flank, Colonel Puller’s 1st and 3rd Battalions encountered minimal opposition as they moved along the relatively flat coastal plain but had to halt their advance when the 1st Battalion was impeded by a reinforced concrete blockhouse. On the right, Colonel Harris’ 2nd Battalion progressed well while staying hidden from Japanese artillery and mortar fire. However, despite reaching their objectives by mid-morning, Harris’ 1st Battalion faced difficulty when Puller’s 2nd Battalion, after making initial gains, was halted by the Umurbrogol defenses. They fought hard to secure Hill 200 but were immediately met with fire from the next ridge. Additionally, Harris’ 3rd Battalion was pinned down by heavy flanking fire from the left. That night, additional armor was sent to the 7th Marines to support the ongoing operations in the south. The next morning, Hanneken’s 3rd Battalion launched a final assault. During the night of D+2, additional armor (tanks and 75mm gun-mounted halftracks) was brought up and at 10:00 on September 18 the advance was resumed. Again progress was painfully slow with many reserve elements being attacked by Japanese from bypassed caves and underground emplacements. At 13:44 elements of Companies A and C reached the southern shores, though the area being assaulted by Company B was still heavily defended. Tank support had withdrawn to re-arm and before Company B was in a position to resume the attack, a bulldozer was needed to extricate the gun-mounted half-tracks, which had become bogged down. At that time, several explosions were heard from the Japanese defenses and it was found that remaining Japanese defenders had finished the job for the Marines. The final handful leaped from the cliff tops into the sea in an effort to escape, only to be picked off by Marine riflemen. With the taking of the two promontories, the southern part of Peleliu was secured. 1/7 and 3/7 squared themselves away for a well-earned rest, while headquarters reported "1520 hours D+3, 7th Marines mission on Peleliu completed." Unfortunately, this was not quite the case. Despite the slow progress and intense Japanese resistance, the Marines managed to secure the southern portion of Peleliu by the end of September 18. At the same time, the 1st and 5th Marines continued their fierce and costly push north. On the right flank, Colonel Harris’s 2nd Battalion faced only sporadic resistance as it cut through the dense jungle. The Americans eventually reached a causeway leading east to Peleliu’s northeastern peninsula, a potentially dangerous obstacle to their advance. After a successful patrol, Harris opted to call in an airstrike before crossing, but the strike missed its target and hit the area while the Marines were crossing. Despite this, the bridgehead was established, though further casualties were incurred due to friendly artillery and mortar fire. With this new foothold, Harris redirected his 3rd Battalion eastward across the causeway to support the 2nd Battalion’s advance. On the left flank, the 1st Marines, having sustained 1,236 casualties, were urged by Rupertus to "maintain the momentum." This led Colonel Puller to commit all available reserves, including engineers, support personnel, and Hanneken’s reserve 2nd Battalion. The 1st Marines suffered about 240 casualties during the 17th and in Japanese counterattacks the ensuing night; the 3rd Battalion was reduced to about one third of its original strength; and two companies of the 1st Battalion were practically finished as fighting units. On the other hand, there was some reason for optimism. Progress on the 17th had been measured in hundreds of yards in the rough, high ground at the southern end of the central ridges and strong Japanese resistance had been overcome. Whatever optimism may have existed was not to last too long. On the 18th, in what the Marine Corps' history of the operation characterizes as "savage and costly fighting," elements of the 1st and 7th Marines managed to advance more than 500 yards in the center, principally along the ridge lines and hills oriented north and south. But the advance during the day was held up at a group of peaks which seemed at first to form a continuous ridge line that was oriented more east and west than the rest of the Peleliu ridges. Soon, the name Five Sisters came to be applied to a cluster of peaks forming the western side of the terrain feature. A towering hill at its eastern extremity, separated from Five Sisters by a saddle, was designated Hill 300, or Old Baldy. With the 7th Marines held up in the center, at Five Sisters, the units on both sides of the central ridges halted so as not to create exposed flanks. Puller’s 3rd Battalion made progress along the coastal plains but had to pause to stay in contact with other units. Meanwhile, the 2nd Battalion struggled against the Umurbrogol Mountains, capturing Hill 210 before being forced to withdraw due to a fierce Japanese counterattack on Hill 200 behind them. At Anguar, following a three-hour artillery bombardment supported by aircraft, General Mueller’s 321st and 322nd Regiments resumed their advance north and west with tank support. After linking their advances, Colonel Venable pushed west and reached the high ground where Major Goto had established his main defenses, while Colonel Dark made significant progress south until his forces encountered the formidable defenses at Green Beach. The night of 18-19 September was noisy and nerve-racking all along the front and few troops got much sleep. Minor Japanese attacks harassed the exposed salient held by the 3d Battalion, 322d Infantry, while bats and large land crabs helped the Japanese to create distraction and started troops firing on nonexistent enemy infiltrators. Apparently no casualties resulted either from Japanese action or indiscriminate small arms fire. Friendly artillery fire did, however, cause some casualties. About 2030, four or five 105-mm. shells from the 316th Field Artillery Battalion hit the lines of the 2d Battalion, 321st Infantry, killing 4 men and wounding 15 others. The artillery fire was stopped before further damage could be done. On September 19, following a night of numerous Japanese infiltrations and small-scale counterattacks, the 322nd Regiment swiftly secured Saipan Town and advanced to the north shore of Garangaoi Cove. Meanwhile, the 321st Regiment successfully attacked and captured the Green Beach fortifications from their vulnerable side. To manage the exposed Japanese forces on the beaches, Dark’s 2nd Battalion, supported by tanks, maneuvered left and progressed down the southwest of the island, halting just short of the shoreline by nightfall. At Peleliu, Harris’ Marines made headway towards the Ngardololok area, overcoming light resistance and quickly dispatching the few enemy stragglers they encountered, reaching Purple Beach by day's end. However, in front of the O-3 line, Puller’s weary troops, having endured a grueling night of Japanese counterattacks, resumed their assault on the Umurbrogol Mountains. Despite some local advances, by evening on 20 September the 1st Marines had been stopped and, ". . . as an assault unit on the regimental level, had ceased temporarily to exist," having suffered almost 1,750 casualties, well over half its strength. Relief was absolutely necessary, not only because casualties were heavy but also because the survivors were physically exhausted from heat, lack of water, and continuous combat. Elements of the 7th Marines therefore relieved all 1st Marines units except those along West Road. While the 7th Marines took over from the exhausted 1st Marines on the right, the 5th Marines continued their advance through western Peleliu, securing its two peninsulas, including Island A and Ngabad Island, by September 21. General Mueller, concerned lest the Japanese reported on the south break through gaps or weak points in the forward lines, had special defenses in depth set up at RED and BLUE Beaches, utilizing Shore Party and antiaircraft troops. All units were alerted to expect Japanese attacks during the night. The division expected (and perhaps hoped) that the Japanese still believed to be located in southern Angaur might launch a suicidal desperation charge during the night or at dawn on the 20th. The night proved very quiet until, toward morning, some small, scattered Japanese parties infiltrated through the lines of both regiments. There was no banzai effort--rather, these Japanese troops were apparently attempting to escape to the northwest hill mass from positions in the mangrove swamp and GREEN Beach 3 areas. Action at dawn was limited to a mopping-up operation directed against four Japanese discovered in the headquarters area of the 2d Battalion, 321st Infantry. By 11:00 on September 20, Mueller reported to General Geiger that all organized resistance on Angaur had ended and that the island was secure. General Mueller's statement was probably prompted by his realization that the remaining Japanese were compressed into the northwest hills and by the reports that about 850 of the enemy had been killed through the 20th. This casualty figure was an overestimation. Probably fewer than 600 Japanese had been killed through the 20th, and Major Goto still had possibly 750 men with which to conduct an organized defense in the northwest. On orders from General Inoue, Goto planned no final banzai attack which would decimate his forces. Instead he withdrew over half his force to rugged terrain and emplaced them in natural or prepared fortifications. His lines of defense in the northwest were well conceived; many of his positions were mutually supporting; the amphitheater configuration of the bowl provided him with defensive areas whence heavy cross fires could be directed at attackers; the broken coral, with its crevices, fissures, caves, and ridgelets, gave him defensive advantages at least as good as those at the Ibdi Pocket on Biak; and he had available a number of artillery and anti-tank weapons, heavy and light mortars, and heavy and light machine-guns, most of them so emplaced as to give maximum support to his riflemen. In addition, he could still exercise effective control over the men he had gathered in the Lake Salome bowl. For whatever it was worth, Goto was ready to conduct a protracted defense, though the best he could hope for was to tie down the 322nd Regiment. Nevertheless, the real issue at Angaur--securing the prospective airfield area--had already been decided. To the north, while southern Angaur was being secured, Venable’s men were probing the enemy's northwestern defenses with a series of company-sized attacks. These attacks allowed the Americans to gather crucial information about Goto’s remaining positions, centered around the Lake Salome bowl. Venable discovered that organized resistance was still strong, prompting him to rearrange his units for a final push. Following a heavy artillery and air bombardment, the 322nd Regiment attacked the bowl with tank support, initially making some gains but soon encountering obstacles due to the terrain and enemy fire. By the end of September 21, Venable deemed the newly gained positions too exposed and decided to withdraw to the previous night's defenses. Meanwhile, the 1st and 7th Marines continued to face heavy casualties as they fought through the Umurbrogol Mountains, with the latter advancing less than 175 yards after two days of intense combat. Nakagawa’s fierce defenders managed to halt the 1st Marine Division on the rough and well-defended terrain, resulting in a total of 4,000 casualties by this time. After visiting the front, Geiger decided to replace the battered 1st Marines with Dark’s 321st Regiment, which had suffered minimal casualties and had completed its mission at Angaur. The 1st Marines by this time reported 1749 casualties. One Marine later described the fighting in the Umurbrogol, which attests to the level to which the 1st Marines had deteriorated: "I picked up the rifle of a dead Marine and I went up the hill; I remember no more than a few yards of scarred hillside, I didn't worry about death anymore, I had resigned from the human race. I crawled and scrambled forward and lay still without any feeling towards any human thing. In the next foxhole was a rifleman. He peered at me through red and painful eyes. I didn't care about him and he didn't care about me. As a fighting unit, the 1st Marines was finished. We were no longer human beings, I fired at anything that moved in front of me, friend or foe. I had no friends, I just wanted to kill." OnSeptember 19, he also dispatched Colonel Arthur Watson's reserve 323rd Regiment to secure Ulithi Atoll. After a successful reconnaissance mission, the infantrymen landed on September 22, discovering that the atoll’s airfield and seaplane base had been abandoned by the Japanese. The Americans later established a major advanced fleet anchorage, a Marine airbase, and a Navy seaplane base there. Ulithi Atoll contained a 300-berth anchorage and a seaplane base. Occupation of these Western Caroline islands provided still another base from which future operations against the enemy could be supported. The construction of an airstrip on Ameliorat…

    Last time we spoke about the invasion of Morotai. After capturing the Marianas and Sansapor, the Allies planned to invade the Palaus and Halmahera. The Japanese stationed the 14th Division at Palau and the 32nd Division at Halmahera. General Ishii, with 11,000 troops, defended Halmahera's nine airfields, while Major Kawashima led 500 Formosans on Morotai. Meanwhile Colonel Nakagawa commanded the forces at Peleliu with extensive defenses, emphasizing attrition tactics. The Allies planned Operation Stalemate for Peleliu and Angaur, with General Geiger's corps set to land on September 15. Aerial reconnaissance and submarine missions informed their strategy. At Morotai, Operation Tradewind was executed by General Krueger’s 31st Division. Supported by air and naval bombardment, Allied troops swiftly secured key areas, encountering minimal Japanese resistance. These operations were part of broader Allied strategies involving coordinated air support and subsequent invasions in the region.

In last weeks episode we talked about the plans and preparations for the invasion of Palau. General Rupertus’ 1st Marine Division was assigned to assault Peleliu while General Mueller’s 81st Division would conduct a dual-pronged landing on Angaur. Meanwhile, Admiral Hoover’s land-based aircraft, General Kenney’s Allied Air Forces, and Admiral Mitscher’s carrier-based aircraft carried out an extensive neutralization program against Japanese airfields within range of Palau. When fighter planes of three fast carrier groups started sweeping over the Palaus on September 6, they found that the efforts of the Southwest Pacific's land-based bombers had succeeded in eliminating many ground targets. Nevertheless, fighters and bombers of the three groups started full-scale attacks on all the principal islands in the Palaus the next day. There was no air opposition, nor had there been any on the 6th. On the 8th, because observable targets were scarce, the weight of attack was reduced, and the carriers began preparing to move to Philippine waters. During their three days at the Palaus, the carrier-based planes flew about 1470 sorties, causing extensive damage to ammunition and supply dumps, barracks, warehouses, and a number of miscellaneous buildings. The groups claimed destruction of only four enemy aircraft, while losing eight of their own. Admiral Fort’s slower-moving tractor groups, responsible for transporting both divisions to the islands, departed Guadalcanal with their respective screening forces on the morning of September 4. Four days later, fast transports and LSDs also set out to rendezvous with them in the early hours of September 15 after an uneventful voyage. In the interim, Admiral Davison’s carrier group launched a final sweep over the Palaus on September 10. The next day, Rear Admiral Jesse Oldendorf’s Western Fire Support Group and Rear Admiral Ralph Ofstie’s escort carriers arrived to begin the naval gunfire bombardment. Over the following three days, approximately 2,200 tons of naval projectiles were successfully fired on Peleliu. While Japanese positions pinpointed by the fire support ships were generally destroyed, many hidden by natural or man-made camouflage remained intact, as did those in areas not accessible to naval gunfire. Minesweepers cleared the 670 mines laid by the Japanese in the Peleliu-Angaur region and at least 240 more in the Kossol Passage. Nearly 175 mines were destroyed in the four days leading up to the landings, with the remaining mines marked at the cost of one minesweeper. Underwater demolition teams also began clearing obstacles from the landing beaches on September 12, providing the Japanese with clues about the Allied landing plans, leading them to hastily lay many land mines in the last few days. By 05:15 on September 15, Fort’s transports had finally gathered off the Palaus and taken their assigned positions in the transport areas, ready for the landings to begin. Under clear skies, the small craft and amphibian vehicles of the assault waves formed up without difficulty and moved toward the reefs in front of Peleliu’s White and Orange Beaches. At 05:30, Oldendorf’s cruisers and destroyers started the pre-landing bombardment of the beaches, which was scheduled to cease at 07:50 to allow the carriers to conduct a final sweep. Ten minutes later, the first assault wave began advancing, supported by an LCI rocket barrage and aerial strafing attacks. However, the pre-landing bombardment had been inefficient, leaving many Japanese positions intact. Artillery and mortar fire quickly targeted the American amtracs, with several LVTs taking direct hits. Approximately 26 were destroyed during the landings, their burning hulks cluttering the beaches. Despite the smoke from Japanese fire and burning amtracs, the first wave reached the shore at 08:32. Colonel Chesty Puller’s 1st Marines landed on the left, Colonel Harold Harris’ 5th Marines in the center, and Colonel Herman Hanneken’s 7th Marines on the right. For those of you interested, a rather famous marine was with Harris’s 5th marines this day. Serving with K Company, 3rd battalion, 5th Marines was Eugene Sledge, the author of “with the Old Breed” probably the most famous Pacific War book of all time. If you are a fan of the HBO series: the Pacific, it was based loosely off this book amongst others. I think overall with the Old Breed does an outstanding job, particularly for when it was written, to showcase the brutal reality of the war in the Pacific. Eugene Sledge did not sugar coat things or gloss over terrible things he saw his fellow marines do, such as ripping out gold teeth from dead or even alive Japanese as well as taking human trophies like skulls or hands. Here is a passage: We learned that our battalion would leave Peleliu as soon as a ship was available to transport us back to Pavuvu. By day we rested and swapped souvenirs, but we had to be on the alert at night for possible Japanese movement. To the south we could hear the constant rattle of machine guns and the thud of mortars and artillery as the 81st Infantry Division kept up the pressure around the Umurbrogol Pocket. “Have you gone Asiatic?” I gasped. “You know you can't keep that thing. Some officer'll put you on report sure as hell,” I remonstrated as I stared in horror at the shriveled human hand he had unwrapped. “Aw, Sledgehammer, nobody'll say anything. I've got to dry it in the sun a little more so it won't stink,” he said as he carefully laid it out on the rock in the hot sun. He explained that he thought a dried Japanese hand would be a more interesting souvenir than gold teeth. So when he found a corpse that was drying in the sun and not rotting, he simply took out his kabar and severed the hand from the corpse, and here it was, and what did I think? “I think you're nuts,” I said. “You know the CO will raise hell if he sees that.” “Hell no, Sledgehammer, nobody says anything about the guys collecting gold teeth, do they?” he argued. “Maybe so,” I said, “but it's just the idea of a human hand. Bury it.” He looked grimly at me, which was totally out of character for his amiable good nature. “How many Marines you reckon that hand pulled the trigger on?” he asked in an icy voice. I stared at the blackened, shriveled hand and wondered about what he said. I thought how I valued my own hands and what a miracle to do good or evil the human hand is. Although I didn't collect gold teeth, I had gotten used to the idea, but somehow a hand seemed to be going too far. The war had gotten to my friend; he had lost (briefly, I hoped) all his sensitivity. He was a twentiethcentury savage now, mild mannered though he still was. I shuddered to think that I might do the same thing if the war went on and on Its a gripping read, highly recommend it, especially for quote en quote normie friends you might want to get into the Pacific War. Back to the story.Rupertus’ objectives for the first day were to push inland 300 yards to objective line O-1, then attack and capture O-2. Landing simultaneously with the fourth wave were the division's tanks (M-4 Shermans). Because of their excellent waterproofing for the operation, they successfully negotiated the reef, where the worst of the underwater obstacles had been removed by UDTs, and continued toward land in six parallel columns led by their respective LVT guides. The enemy fire, however, proved so intense that over half of 30 tanks organic to the division suffered from one to four hits during the 10 minutes necessary to cross the reef. In the 1st Marines' zone, for example, only one of the assigned tanks escaped being hit during the trip ashore. only three, however, were completely knocked out of action. "Thus within a half hour after the initial landing the infantry had full tank support--a record unsurpassed in any previous Marine landing in the Central Pacific, except for the Marshalls." To make matters worse, no sooner had the lead elements of 3/1 landed and advanced less than 100 yards inland, than they found themselves confronted by a most formidable natural obstacle, a rugged coral ridge, some 30ft high. This had not shown up on any maps. Worse, the face of this ridge (christened "The Point" by the Marines) was honeycombed with caves and firing positions which the Japanese had blasted into the coral and had turned into excellent defensive positions which resisted all initial assaults. Even after tanks arrived to support the assault troops attempting to storm the northern portion of the ridge, they stumbled into a wide, deep anti-tank ditch, dominated by the ridge itself. Here they came under severe and accurate enfilading fire and were pinned down for hours. The loss of much communication equipment further left Puller and Rupertus unaware of the situation on the left flank. A major effort was then launched to assault The Point from the rear. It became apparent to the Marines that The Point was unassailable from the front and so eventually units fought inland and assaulted The Point from the rear. These units, commanded by Capt George P. Hunt, fought their way along The Point for nearly two hours, during which time they succeeded in neutralizing all of the enemy infantry protecting the major defensive blockhouses and pill boxes. The principal defense installation was a reinforced concrete casement built into the coral, mounting a 25mm automatic cannon, which had been raking the assault beaches all morning. This blockhouse was taken from above by Lieutenant William L. Willis, who dropped a smoke grenade outside the blockhouse's embrasure, to cover the approach of his men, and Corporal Anderson who launched a rifle grenade through the firing aperture. This disabled the gun and ignited the ammunition inside the blockhouse. After a huge explosion, the fleeing Japanese defenders were mown down by waiting Marine riflemen. Hunt's surviving 32 men remained isolated on The Point for the next 30 hours, constantly under attack from Japanese infiltrators. Meanwhile, Puller's 2nd Battalion pushed inland about 350 yards against moderate resistance. Despite this success, the 1st Marines' front was divided by two huge gaps. Puller's 1st Battalion was then committed to support the Marines on the left, successfully gaining a foothold on the southern area of The Point, but still unable to close the critical gaps. In the center, Harris' 1st Battalion advanced through coconut groves that provided ample cover, successfully reaching O-1 to link up with Puller's 2nd Battalion in front of the airfield by 09:30. On the right, however, Harris' 3rd Battalion and Hanneken's 3rd Battalion experienced a confused landing and made no progress, with only Harris' Company I reaching O-1 an hour after landing. At 10:30, the two battalions began pushing inland. Harris' Company K rapidly advanced deep into Peleliu's interior under the cover of fairly dense scrub, while the 7th Marines used a large anti-tank ditch to move forward in relative safety. Again I thought it give more flavor if I took a passage from this moment when K Company advanced from Sledge: We started to move inland. We had gone only a few yards when an enemy machine gun opened up from a scrub thicket to our right. Japanese 81mm and 90mm mortars then opened up on us. Everyone hit the deck; I dove into a shallow crater. The company was completely pinned down. All movement ceased. The shells fell faster, until I couldn't make out individual explosions, just continuous, crashing rumbles with an occasional ripping sound of shrapnel tearing low through the air overhead amid the roar. The air was murky with smoke and dust. Every muscle in my body was as tight as a piano wire. I shuddered and shook as though I were having a mild convulsion. Sweat flowed profusely. I prayed, clenched my teeth, squeezed my carbine stock, and cursed the Japanese. Our lieutenant, a Cape Gloucester veteran who was nearby, seemed to be in about the same shape. From the meager protection of my shallow crater I pitied him, or anyone, out on that flat coral Hanneken soon faced strong opposition, leading him to pause his troops and request tank support in the afternoon. The requested tank support became somewhat confused by an unexpected coincidence: the flank battalions of the two assaulting regiments in the center and right were both the 3rd (3/5 and 3/7) with both containing Companies I, K, and L. The unfortunate tank commanders looking for 3/7 who had wandered into 3/5 area due to obstacles - in particular the large anti-tank ditch on Orange 3 - enquired of a body of troops they encountered "is this Company I, 3rd Battalion?" Hearing the right answer in the wrong place, they proceeded to operate with these troops, who were in fact Company I of 3/5 and not Company I of 3/7. Happily, this was one of those confusions of battle that helped more than it hindered. The confusion resulted in a gap between the two regiments as 3/7 paused to take stock of the situation, whereas 3/5 was actually pushing ahead. In an effort to re-establish contact with 3/5, Company L of the 7th Marines worked patrols further and further to the left until its foremost patrol emerged on the southern edge of the airfield. This was completely out of its regimental zone of action and several hundred yards to the rear of the units it was looking for. By this time, Harris’ 2nd Battalion and Hanneken’s 1st Battalion had landed, with Harris’ battalion pushing vigorously northeast, while Hanneken’s battalion dealt with fierce Japanese resistance and a dense swamp to the south as they advanced toward O-1. Concerned about the slow progress on the right and the heavy casualties suffered by Hanneken’s forces, Rupertus decided to land the divisional reconnaissance company. However, the reserve 2nd Battalion, 7th Marines could not be disembarked until the next day. One major Japanese counterattack occurred at around 16:50hrs on D-Day, consisting of a tank-infantry sortie in force across the northern portio…

    Show notes

    Last time we spoke about the end of Operation Dan. In Yunnan, by late July, General Wei's Y Force worked to eliminate Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. The 33rd Army prepared for Operation Dan, anticipating resistance from General Honda's garrisons until September. The fall of Myitkyina prompted Honda to expedite his plans. Reinforcements were expected in Mandalay by September. General Matsuyama's forces, cut off and surrounded, provided support only through radio messages. At Tengchong, Colonel Kurashige vowed to defend against relentless attacks. Chinese forces, after intense fighting and bombing raids, breached the city's defenses. Despite heavy casualties, the Japanese resisted fiercely. Major Kanemitsu’s garrison defended Moung Song with dwindling supplies. The Chinese forces employed siege tactics and underground mines to break Japanese strongholds. The Chinese launched coordinated attacks, capturing key positions and ultimately compelling Japanese retreats.

After the Marianas fell and Sansapor was captured, the Allies set their sights on their next objectives: the Palaus and Halmahera, slated for simultaneous invasion by mid-September. The Japanese had stationed the 14th Division at Palau and the 32nd Division at Halmahera as their primary defenses. The Halmahera-Morotai area had not assumed much importance to the Japanese until early 1944, when they began to develop Halmahera as a focal point for the defense of the southern approaches to the Philippines. In addition to the 32d Division, the Japanese had on Halmahera innumerable service organizations, and they completed or had under construction nine airfields on the island, most of them in northern Halmahera. On that island they concentrated nearly 30,000 men, including at least 11,000 combat troops. On Halmahera, General Ishii commanded approximately 11,000 troops to safeguard nine airfields, despite having already lost most of their air power. Meanwhile, Morotai Island was defended by around 500 Formosans of the 2nd Raiding Unit, led by Major Kawashima Takenobu. General Ishii planned to counterattack from Halmahera if the Allies landed on Morotai, but soon realized Allied air and naval superiority would foil these efforts. Following their defeat in the Marianas, Tokyo reassigned the Bonin Area Group directly under its command and placed the Palau Area Group under the Southern Army, leaving General Mugikura’s 31st Army to defend Truk and other isolated outposts. General Inoue fortified Palau with elaborate defenses along the coast and inland, manned by 21,000 Imperial Japanese Army (IJA) troops, 7,000 Imperial Japanese Navy (IJN) personnel, and 10,000 laborers. The IJN had by 1944 constructed numerous reinforced concrete blockhouses and bunkers plus dug an extensive tunnel system near the end of the northeast peninsula as well as taking full advantage of Peleliu's natural caves. This elaborate, multi-level tunnel system could shelter 1000 troops. These defenses, tunnels, the airfield, and the many support facilities were built by the 204th, 214th, and 235th Construction Battalions, mostly manned by Koreans and Okinawans. Detachments of the guard forces manned eight 120mm dual-purpose, and about three 200mm coast defense guns. There was no ammunition for the 200mm short guns nor did any ships report being fired on by coast defense guns. The 114th and 126th Anti-aircraft Units manned single and twin-barreled 25mm automatic guns (estimated at 30) and 13.2mm machine guns. A dozen 20mm cannons, removed from destroyed aircraft, were set up on makeshift mounts, mostly around the airfield. His strategy emphasized prolonged attrition over suicidal charges, aiming to exhaust the American forces. In preparation for the intense pre-landing bombardment, Inoue instructed his troops to utilize natural terrain features like coral caves and sinkholes, tactics that proved effective against the advancing Allies.Based in Koror, the Japanese commander stationed Colonel Nakagawa Kunio’s 2nd Regiment on Peleliu, the reinforced 1st Battalion of the 59th Regiment on Angaur, and deployed the 15th and 59th Regiments across Babelthuap and other islands. Major-General Yamaguchi Takeo’s 53rd Independent Mixed Brigade defended the central islands, complemented by 4,000 personnel from the Imperial Japanese Navy on Peleliu. Prior to General Inoue’s arrival in the Palaus, the defense of the Palaus had been under the command of Vice-Admiral Ito Yoshioka. Upon his arrival on Koror, where he established his headquarters, Inoue appointed Colonel Nakagawa Kunio as Peleliu's new commander, with his 2nd Regiment (Reinforced). Nakagawa was a most able commander, possibly one of Japan's finest defensive tacticians, in the same league as General Kuribayashi on Iwo Jima. Nakagawa would make full use of all his defenses and troops on Peleliu, making the Americans pay dearly for every inch, as he had been ordered to do. Although a very capable commander, the appointment of an Army colonel over a Navy vice-admiral caused a great rift between the Army and Navy on Peleliu, which deteriorated into farce. To resolve matters and calm the Navy down somewhat, Inoue sent Major-General Murai Kenjiro from his headquarters on Koror Island to Peleliu to provide the Army with sufficient rank to satisfy the vice-admiral's honor, although the defense of Peleliu seems, to practical purposes, to have remained in the hands of Nakagawa. It appears that Murai, after inspecting Nakagawa's defensive works and battle plans for the defense of Peleliu, was content to let Nakagawa continue without interference from himself, lending only the weight of his rank to acquire the required cooperation of the Navy elements on Peleliu. Nakagawa, divided the island into four defense sectors, each manned by an infantry battalion. His 1st Battalion, alongside the 14th Division Tank Unit and Engineer Company, served as a mobile reserve for counterattacks against potential landings. Meanwhile, Admirals Nimitz and Halsey had been planning Operation Stalemate, targeting Palau since May 29. Originally slated for September 8, General Geiger’s 3rd Amphibious Corps would assault Peleliu and Angaur, with General Hodge’s 24th Corps landing on Babelthuap. Intelligence was gathered by aerial reconnaissance photographs. Also, in June 1944 the submarine USS Seawolf (SS-197) carried out photographic reconnaissance of the invasion landing beaches. A further reconnaissance was carried out by the submarine USS Burrfish (SS-312) on Peleliu and Yap beaches. An 11-man reconnaissance group of underwater demolition team (UDT) frogmen landed on the Peleliu beaches from the Burrfish for closer investigation relating to water depth, location of potholes and sandbars, and obstacles. With thousands of Japanese on the island they understandably did not reconnoiter inland, and the rugged terrain of the interior would come as an unpleasant surprise to the Marines. A similar operation was carried out on the Yap invasion beaches, but this time only two of a five-man reconnaissance team made it back to the pick-up point. After several unsuccessful attempts to locate their missing comrades the remaining two men returned to the Burrfish. After this incident, Admiral Nimitz banned any further missions of this type. Given delays in the Guam operation, Operation Stalemate was canceled on July 7, replaced by Stalemate II. An unusual staff arrangement was established to plan Stalemate II. IIIAC was committed to take Guam under General Geiger. The IIIAC staff would thus be unable to plan the Palaus operation, which it was to execute. Consequently, Major General Julian Smith, designated to command the Expeditionary Troops, was tasked to plan the operation using his own small staff augmented by some IIIAC staff officers. This temporary planning staff was designated X-Ray Provisional Amphibious Corps. It would plan the operation and IIIAC would execute it – an awkward arrangement, but necessary in order to maintain the increasing tempo of operations. As Commander, Expeditionary Troops, Smith was also to be in control of all ground action in the western Carolines; a position roughly analogous to that of General Krueger of ALAMO Force in the Southwest Pacific. X-Ray was finally dissolved on August 15, 1944. This revised plan scheduled Geiger’s forces to land on Peleliu with the 1st Marine Division and on Angaur with the 81st Division on September 15, while the 77th Division remained in floating reserve and the 5th Marine Division in area reserve. Then, on October 8th, the 24th Corps planned to launch an assault on the islands of Yap and Ulithi in the western Carolines. This was aimed at securing an additional airfield and fully neutralizing Truk and the remaining islands in the group. For this operation, Halsey divided his 3rd Fleet into two main echelons: his Task Force 30, which included covering forces such as Admiral Mitscher’s Fast Carrier Task Force (now Task Force 38), and Admiral Wilkinson’s Task Force 31, the Joint Expeditionary Force. At Peleliu, General Rupertus’ 1st Marine Division was to land with five battalions advancing over the White and Orange Beaches on the southwest coast. The 1st Marines were to land on the left, pushing up the western shore to clear Japanese forces from ridges overlooking the airfield; the 5th Marines would land in the center to secure the airfield; and the 7th Marines on the right to capture the southern end of the island. Meanwhile, at Angaur, Major-General Paul Mueller’s 81st Division planned a two-pronged amphibious assault. The 322nd Regiment was to land on Red Beach on the northeast coast, while the 321st Regiment would land on Blue Beach about 2000 yards to the southeast. Both forces would then push inland to secure a first phase line approximately 300 yards from the beaches, before continuing their advance west and south. The reserve 323rd Regiment was tasked with a feint landing at Beach Black on the northwest coast, with potential deployment to Ulithi if the Palau operations proved successful. Meanwhile, General MacArthur aimed to establish an airbase in the Halmahera area, strategically positioned between the Vogelkop and Mindanao. This location would provide crucial flank protection against Japanese forces in the Dutch East Indies and support land-based operations for the upcoming invasion of Mindanao. Optimistically, in mid-June, MacArthur had tentatively scheduled the invasion of Mindanao for October 25. Nimitz, however, believed that MacArthur's hope of reaching Mindanao by October 25 was too optimistic. During conferences at Pearl Harbor in July, called at the suggestion of Nimitz to coordinate Southwest and Central Pacific plans for the Morotai, Palau, and Mindanao operations, Southwest Pacific planners learned that less amphibious craft and assault shipping could be made available to them than had previously been anticipated. Moreover, restudy of range and weather factors made it appear somewhat risky to depend upon the ability of Morotai-based aircraft to provide air support for Southwest Pacific forces on Mindanao after carriers had to leave the latter area and before airdromes could be developed there. To obtain adequate land-based air support for the Mindanao invasion force, MacArthur returned to discarded plans to seize air-base sites on the Talaud Islands, about equidistant from Morotai and Sarangani Bay, Mindanao, where the first landings in the Philippines were then scheduled to take place. The employment of amphibious means for the Talaud operation would delay preparations for Mindanao, as would the development of airdromes on the Talauds. Finally, to have the invasion of Mindanao take place much before the middle of November would involve a conflict in timing with anticipated employment of assault shipping and carrier support by Admiral Nimitz for the occupation of Yap and Ulithi in the western Carolines, an operation scheduled for the first week in October. MacArthur therefore revised his program to call for the invasion of Morotai on September 15, the Talauds on October 15, and Mindanao on November 15. As Allied carriers were engaged in the Palau operation, MacArthur needed a target within range of fighters and medium bombers stationed at Sansapor. Thus, Morotai Island was chosen for Operation Tradewind due to its perceived light defenses and ample space for airfield and light naval base facilities. General Krueger selected the 31st Division and the 126th Regiment, totaling approximately 28,000 troops under the overall command of General Hall's 11th Corps, for this operation. Admiral Barbey's Task Force 77, comprising 12 destroyers, 2 APAs, 5 APDs, 1 LSD, 39 LCIs, 12 LSTs, and 12 LCTs, along with a covering force led by Admiral Berkey and an escort carrier force under Rear-Admiral Thomas Sprague, facilitated the amphibious movement. Additionally, Vice-Admiral John McCain's fast carrier group provided support. Anticipating minimal resistance, the landings were planned near prospective airfield sites on the Doroeba Plain in southwest Morotai. General Hall's strategy involved the 155th and 167th Regiments landing on Red Beach on the southwestern coast to swiftly capture the abandoned Pitoe Drome and secure the new Pitoe Airfield site. Meanwhile, the 124th Regiment landed at White Beach, about 1500 yards to the south, to secure the Gila Peninsula and the Wama Airfield site. The reserve 126th Regiment was scheduled to land the following day, with its 1st Battalion initially supporting the 124th Regiment's operations at the beachhead. Both the Palau and Morotai operations were supported by a coordinated strategic air support program. Admiral Hoover's land-based aircraft were tasked with neutralizing Japanese airfields at various islands including Yap, Woleai, Truk, Ponape, Pagan, Bonin, and Marcus Islands. Concurrently, General Kenney's Allied Air Forces reinforced these efforts and targeted enemy air centers in Palau, Mindanao, western Dutch New Guinea, Halmahera, the Talaud Islands, the Moluccas, the Celebes, and the Arafura Sea islands. Additionally, Mitscher’s fast carriers embarked on an ambitious campaign, launching strikes from the Bonin and Volcano Islands to the Palaus and Mindanao between late August and the start of the invasions. This strike had a twofold objective: the temporary neutralization of Japanese airfields on those island groups and, more important, the creation of a diversion on the north preceding stronger attacks against targets in the Philippines and western Carolines. Carrier action in the latter area was to begin on 6 September, with strikes on the Palaus, Yap, and Ulithi. The bulk of the carrier forces was to leave the western Carolines on the afternoon of the 8th to take up positions off Mindanao. Japanese airfields on Mindanao presented difficult targets because they were scattered over that large island, but it was believed that the cluster of airfields and associated installations in the Davao area would provide profitable targets for carrier-based ai…

    Last time we spoke about the battle of the Driniumor River. In July and August, American and Japanese forces clashed near Afua in New Guinea. Troop A of the 112th Cavalry engaged Japanese units, pushing them back temporarily. Troop C replaced Troop A but was soon isolated by Japanese attacks. The American TED Force, including the 124th and 169th Infantry, launched a counteroffensive, facing heavy resistance. Despite supply and terrain challenges, TED Force advanced, forcing the Japanese to gradually withdraw. By early August, the Japanese launched fierce and desperate attacks, but American defenses held firm. TED Force continued its advance, encountering further fierce Japanese resistance but successfully disrupting their supply lines. The Japanese, suffering heavy losses, were finally forced to begin a general retreat, as the American forces consolidated their positions by early August. It seemed Green Hell was still living up to its dreadful nickname. This episode is Operation Dan Welcome to the Pacific War Podcast Week by Week, 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 you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. This week we are picking up with the action along the CBI theater. In Yunnan, by the end of July, General Wei's Y Force was still engaged in efforts to eliminate the resilient but small Japanese garrisons at Tengchong, Mount Song, Pingda, and Longling. Simultaneously, the 33rd Army was striving to accelerate preparations for Operation Dan, anticipating resistance from General Honda's main garrisons until September's end. Following the fall of Myitkyina in August, Honda recognized the need to expedite his offensive plans, despite delays in the deployment of the 2nd and 18th Divisions. Additional reinforcements from the 49th Division were expected in Mandalay by September, bolstering Honda's position. Meanwhile, General Matsuyama faced the challenge of isolated garrisons cut off from his 56th Division, surrounded by superior enemy forces. With his main forces focused on imminent offensive preparations, Matsuyama could only provide moral support through radio messages. Colonel Matsui's recent successes reduced Chinese activity on the Mangshi front, allowing for the rehabilitation of the 113th Regiment by August, despite occasional small-scale raids. At Tengchong, Colonel Kurashige resolved to defend the Walled City to the last man against relentless infantry assaults, air bombardments, and continuous enemy artillery preparations. Compared with the defenses of Lameng, the positions at Tengchong were much less effective due to the factors of disadvantageous terrain and the lack of time to make defense preparations. Tengchong Castle covered an area slightly over a half-mile square; and was surrounded by a rampart 16 to 20 feet in height and over six feet thick at the top. Although the rampart had a stone facing and was backed with clay, it was not proof against an artillery bombardment and considerable work was required to strengthen it. Concrete or stone pillboxes were constructed adjacent to all gates and at the four corners. Shelters were built to protect guns and machine guns mounted on the rampart as well as for the troops and supplies inside the wall. Other entrenchments were prepared within the castle itself. While these measures greatly strengthened the defenses, the castle was still not proof against an intensive air or artillery bombardment. Recognizing the southeast as the primary avenue of approach, General Huo directed his forces to concentrate their main efforts in that direction. On August 2, following another bombing raid by twelve B-25s that created a gap fifteen feet wide, the 36th and 116th Divisions initiated a new general assault. The Japanese quickly worked to repair the breach and fired machine guns to cover it. It was only after concentrating guns, rockets, and flamethrowers on the southwest pillbox, along with five waves of fighter cover fire, that the Chinese were able to position scaling ladders against the wall. Two companies then seized the top of the wall just east of the southern corner on August 3. Overnight, Kurashige led a successful counterattack that restored defenses along the rampart, except for one platoon that held its ground all night. This platoon's resilience allowed Chinese reinforcements to pass through the breach on August 4 and seize a pillbox inside the city. With the walls breached, the fall of Tengchong became inevitable, but the determined defenders continued to resist fiercely in the coming days, inflicting heavy casualties on the Chinese attackers. Meanwhile, Major Kanemitsu’s Lameng Garrison defended Moung Song fiercely. After the Hondo Position fell, the 308th Regiment resumed the advance on 3 August it had flamethrowers which it used with devastating effect to take the crest of Kung Lung-po. There the Chinese found several Japanese tankettes, which had been dug in for use as pillboxes. Despite repelling enemy attacks with great effort, the Japanese faced dangerously low ammunition supplies. As a result, Kanemitsu decided to raid the 8th Army's artillery positions and supply dumps to replenish his ammunition stocks. Twenty-nine men, selected from the artillery battalion, were divided into two teams for the purpose. One team was to raid the artillery positions on Shirakabe and Haraguchi Hills as well as to attack motor vehicles on the road between Lameng and Huitung Bridge. The second team was to operate in the area to the south and west of the Gake and Hondo Positions. On the night of August 9, seven groups of Japanese volunteers launched a surprise attack, destroying several howitzers and seizing light weapons and ammunition. Despite Kanemitsu’s initial success and his troops' resilient defense against Chinese infantry assaults, General Song opted to revert to conventional siege tactics starting August 11. His divisions began digging tunnels beneath key Japanese strongholds in the Mount Song triangle, each tunnel stretching 22 feet to accommodate two powerful mines aimed at enemy pillboxes.One mine held 2,500 pounds of TNT, the other mine held 3,500 pounds of TNT. The mines detonated on August 20, causing significant damage that engineers exploited swiftly with flamethrowers, capturing Kanemitsu’s primary stronghold. In one pillbox forty-two Japanese were buried alive, of whom five were rescued. The prisoners stated that they had been asleep and had never suspected that they were being undermined. At 0920 the 3d Regiment against light opposition took the few strongpoints that remained on Sung Shan proper. In spite of particularly heavy pressure being exerted against the Sekiyama Position, the enemy had made little progress. However, on 19 August, following a heavy bombardment three tremendous blasts shook the Sekiyama Position. The Chinese, becoming discouraged with trying to storm the position, had tunneled under it, the defenders of the Sekiyama Position were virtually annihilated and the position fell to the enemy. On 23 August the Lameng Garrison regrouped to make final resist- ance in the Otobeyama, Nishiyama, Matsuyama, Yokomata and Urayama Po- sitions. The total number available for defense had been reduced to about 150 men, all of whom were wounded, some seriously. Even those who had lost an arm or a leg were propped up in positions where they could fire a rifle or sight a gun. The Lameng Garrison continued to resist in scattered pockets, launching futile counterattacks, Song recognized the battle's turning point. During the latter part of July and early August, the Yunnan Force made new troop dispositions and moved in three divisions to attack the town. The main force of the Chinese 87th Division was on the east front, with an element along the Tien-Mien Road; the New 28th Division was between the two elements of the 87th; elements of the 1st Honor Division were on the north front with the New 39th Division on the south and west of Longling. At dawn on 14 August, preceded by an intense concentration of artillery fire and air bombardment, the Chinese forces launched a coordinated attack from all sides. Hill 6 bore the brunt of the enemy attack for eight hours but managed to hold, as did the defenders on the main line of resistance. After the attack had ceased, the Garrison spent the entire night rebuilding defenses, using rubble and half-burned mate- rial from the town. However, five days later, Chinese forces captured the eastern hills, weakening the entire Japanese defensive line. Consequently, by August 23, the eastern front collapsed, compelling the Japanese to retreat from their main defensive positions to reserve positions within the town. Matsuyama was aware that under the current conditions, Longling would likely fall before September began. While the timely reinforcement of the 3rd Battalion, 148th Regiment would enable the garrison to hold out for a few more days, he understood the urgency of accelerating the Dan offensive to relieve Longling. Starting on 26 August, the 2nd Division began moving from Namhkam to Mangshih under cover of darkness, requiring three nights to complete the movement. Shortly thereafter, the headquarters of the 16th Regiment was called from Bhamo to Mangshih and Col. Hara Yoshimi, commanding officer of the 2nd Reconnaissance Regiment, succeeded Col. Sakai as commander of the Bhamo Garrison, which was placed under 18th Division control. On 30 August, the Division conducted a war game followed by a conference to brief subordinate commanders on the plans and missions of the Dan Operation. With the recent arrival of the 4th and 146th Regiments, Matsuyama planned to send Matsui’s Task Force and the 146th Regiment northwestward to clear the western sector. Meanwhile, General Okazaki’s 2nd Division would attack northeastward to defeat the main enemy force in the eastern sector, thus fully relieving Longling. Subsequently, the 56th Division would advance towards Tengchong, while the 2nd Division moved towards Lameng, to relieve both isolated garrisons. However, before this offensive could begin, new developments emerged from Tengchong. Realizing that assaults on the ramparts were too costly, Huo ordered his Chinese troops to start tunneling under the walls. Additionally, air attacks increased in intensity, and on August 13, several large bombs struck the headquarters, killing Kurashige and leaving the garrison nearly leaderless. The following morning, after a heavy artillery bombardment of about 20,000 rounds, Huo launched his second general attack. Despite the garrison's determined defense against Chinese attempts to breach or scale the ramparts, Huo reinforced his southern assault with the 198th Division, applying intense pressure. While defenders held against the combined attacks of more than two divisions, the 198th Division, which had made several ineffectual attacks in the northwestern sectors, was brought south to reinforce the units already there. Three divisions pitted against the badly damaged southern wall could not be held off and Chinese troops began infiltrating beyond the rampart. The garrison launched successive counterattacks and, while they were successful in driving the enemy out on the first two occasions, the third counterattack so exhausted the defenders that the enemy held the southwest corner of the compound. The Chinese were not, however, able to make any appreciable headway in breaching any other part of the castle's defenses. Three days later, following another heavy air and artillery bombardment that succeeded in making seven breaches in the southern rampart, the Chinese resumed the offensive and managed to force the garrison to relinquish all but the southeast corner of the southern part of the castle compound. On August 22, a fourth attack was then launched; and, in spite of valiant efforts by the defenders, the west gate of the castle was finally taken by the 198th Division early in the morning of August 24. The following day, about 500 grenades and medical supplies were dropped by 12 Japanese fighters, which bolstered the garrison’s morale even though their fate was pretty much sealed already. Simultaneously, Matsuyama initiated Operation Dan on August 26, with Matsui’s Task Force struggling for six days to secure control of Komatsu Hill before advancing towards Shuangpo on September 1. The Dan Offensive opened inauspiciously with an unsuccessful attack on Komatsu Hill, about three miles south of Lungling. Launched by the 1st Battalion, of the 113th Infantry (Takeda Battalion), on the morning of the 26th, the attack was thrown back and it was not until the following morning after the 3d Battalion, of the 113th (Murakami Battalion) had been thrown into the attack that the Takeda Battalion succeeded in seizing the western half of the hill. Upon achieving the objective, the Murakami Battalion was withdrawn and the Takeda Battalion was exposed to severe counterattacks which the enemy repeated for four days. The Takeda Battalion sustained extremely heavy losses, including the loss of three company commanders. The Inose Battalion attacked the hill from the northeast on 30 August and succeeded in making contact with the Takeda Battalion the following day but the northern part of the hill still remained in the possession of the enemy. Unable to hold up the advance any longer, the Inose Battalion was left at Komatsu Hill to clean out the remnants of the enemy and the main body of the Matsui Column advanced to Shuangpo on 1 September, fighting their way through enemy resistance. The 146th Regiment successfully bypassed Chinese forces blocking the Tien-Mien Road, reaching the ridge west of Shuangpo. The 113th and 146th Regiments continued their northwestward advance, reaching the Longling River line by September 6, where they nearly wiped out the New 39th Division. Meanwhile, Okazaki assembled his 4th, 16th, and 29th Regiments at Shuangpo, preparing for an offensive. To the south, the 76th Division persisted in defending Komatsu Hill despite heavy casualties. Okazaki directed the 4th Regiment to attack the enemy’s northern positions on September 3, resulting in repeated assaults over the next three days. Despite suffering significant losses, the Japanese were compelled to halt their local offensive. In the meantime, the 16th and 29th Regiments moved northeastward. The 29th Regiment successfully breached enemy positions and linked up with the besieged garrison by September 6. Despite this victory at Longling, subsequent events at Mount Song and Tengchong rendered Operation Dan futile. On August 29, following the fall of the Otobeyama Position, Kanemitsu realized that resistance could only last a few more days. On September 5 Major Kanemitsu sent to the commander of the 56th Division a final radio message: “All of my brave officers and men have determinedly defended our position for 120 days since May 10 with a sublime spirit of self-sacrifice and an attitude of absolute obedience. However, our ammunition has been entirely expended and practically every officer and man is wounded. The final moment has come. We will burn the colors and code books and make a suicide stand with what strength remains. I do not have the words to apologize for the fact that, because of my unresourceful command, we ha…

    Last time we spoke about the fall of Myitkyina. By late July 1944, the Japanese at Myitkyina in northern Burma were facing severe challenges. Despite holding out through a long siege, they were cut off from supplies and suffering heavy casualties. A leadership conflict between Colonel Maruyama and General Minakami further complicated things. Maruyama defended the city intensely, while Minakami aimed to deny Allied access to strategic roads. With depleted forces, including wounded troops trying to escape via the Irrawaddy River, the Japanese defense weakened. Allied forces, reinforced and ready, made significant gains, shrinking Japanese-held areas. On August 1, Minakami agreed to withdraw, and the remaining Japanese began escaping across the river. The Allies launched a final attack, securing Myitkyina on August 3. The 10 week siege resulted in substantial casualties on both sides. This victory allowed the Allies to improve logistical routes and marked a critical point in the Burma campaign.

Last time we were seeing action kick up at the Driniumor River. While the Japanese offensive had initially been successful, General Hall's forces managed to halt the enemy advance and reform their river line by July 15, despite a 1500-yard gap in the center. The Japanese were aware of this weakness in the American lines and exploited it, especially during the night. However, Colonel Starr's 3rd Battalion patrolled this area and occasionally engaged the enemy, killing 135 Japanese on the night of July 14. Despite this, General Cunningham claimed that his South Force had extended its lines nearly 1000 yards beyond its assigned sector without encountering any elements of the 124th Regiment. Consequently, on July 15, Starr concluded that his regiment had not advanced as far south as previously reported and ordered his units to adjust their lines southward and extend their defenses up the Driniumor towards Cunningham's Troop E. The following morning, Starr's 3rd Battalion began moving south to close the gap. As they reached the area by nightfall, Troop E was attacked by two companies of the 1st Battalion, 239th Regiment. While the cavalrymen sought cover, Starr's 3rd Battalion was also attacked by Colonel Nara's 3rd Battalion, which had turned south after its defeat at the Paup villages. This split the American forces in two, with Companies L and M pushing south through increasing opposition to reach South Force lines, while Companies I and K dug in for the night in their current positions. Despite the intense fighting, several Japanese were killed, and the gap was reduced to 500 yards. In the course of the day's fighting the Coastal Attack Force had lost all its artillery and had suffered heavy casualties. Additional losses were sustained on succeeding days, but Major Hoshino and his men were not completely removed as an irritant until the night of 16-17 July. During that night remnants of the Coastal Attack Force, about thirty-five men strong, attacked North Force and 124th Infantry command post installations at Anamo. At 23:00 the group charged out of the jungle southwest of the Anamo perimeter. Repulsed by machine gun fire, the enemy temporarily disappeared, only to reappear at 03:00 on 17 July moving west against Anamo along the beach. Machine gun fire from the American positions broke up this second attack, but about ten minutes later the Japanese tried again, this time moving on Anamo from the north by wading in from the sea. Once ashore, Major Hoshino's men broke up into small groups, attempting to destroy mechanized equipment, automatic weapons positions, and communications installations. The Coastal Attack Force remnants had apparently scouted well, for they were reported to have moved purposefully toward the most important installations and they easily found their way about in terrain they had vacated only four days previously. Whatever Major Hoshino's plans were, they were not realized. About forty of his men were killed and the rest dispersed. Behind them, Hall dispatched Colonel Howe’s 1st and 2nd Battalions to clear the remaining enemy units west of the Driniumor River. Over two days of complex and sometimes uncoordinated company actions, the Americans successfully overran Nara’s stragglers in the area. Further south, as Japanese troops were seen crossing the Driniumor at a fording point about 2,500 yards south of Afua, Cunningham sent Troop A south to high ground behind the Driniumor to halt the Japanese movements westwards. There, the 78th and 80th Regiments, under Major-General Miyake Sadahiko, were assembling for a renewed offensive. Adachi’s new plan involved Miyake striking Afua from the south while the 239th Regiment prepared to move against the Kawanaka Shima area. Additionally, the retreating 237th Regiment and the reserve 66th Regiment were ordered south to join future attacks by the 20th Division, though they wouldn’t arrive until July 25. As the Miyake Force maneuvered into position to the right and rear of Cunningham’s 1st Squadron, Starr struggled to close the gap in the center, which was eventually sealed on the morning of July 18. That night, Miyake launched an attack with two battalions on the 1st Squadron's command post and the adjacent perimeter held by Troop A, successfully pushing them 250 yards to the northeast. Early in the afternoon of 19 July fresh Japanese units began to surround the Troop A position, moving in from the north, northwest, west, and southwest. The 1st Squadron commander called for artillery fire to break up this enemy maneuver. Upon cessation of the fire, Troop A attacked to the south and west for a second time. Driving at least a company of Japanese before it, the troop pushed 600 yards southwest of its original positions astride the Afua-Palauru trail and temporarily disrupted enemy plans to seize the position. About 140 Japanese had been killed during the two days' operation around Troop A. South Force, at the same time, lost 8 men killed and 29 wounded, all from the 1st Squadron, 112th Cavalry. There were strong indications that more attacks might occur in the 1st Squadron area, but Troop A was not destined to take part in any of these actions. It was replaced on the 21st by Troop C. Following this victory on July 21, Troop C relieved the battered Troop A, Howe’s battalions successfully set up a patrol base on the East Branch of Koronal Creek, and Starr’s 2nd Battalion moved to Palauru to provide additional outer security southwest of the airfield. On July 19, the first elements of General Wing’s 43rd Division began landing at Aitape, with the 2nd Battalion, 169th Regiment subsequently taking over about 1,000 yards of the river line on the right of the 124th Regiment by July 22. Meanwhile, Adachi ordered the still-reorganizing Miyake Force to attack Afua from the north and west while General Nakai’s 79th Regiment crossed the Driniumor and attacked from the south. On the evening of July 21, Miyake launched his attack on Troop C’s position, successfully cutting it off from the rest of South Force. While the cavalrymen resisted heavy Japanese attacks, Miyake’s units also repelled Cunningham’s attempts to relieve the beleaguered troop over the next few days. Not knowing what other plans the Japanese might have in mind, General Cunningham was unwilling to pull any more troops away from the river defenses. Moreover, he now considered the position of his right flank untenable. He therefore withdrew Troop B north of Afua about 1,000 yards and used the unit to form a new defense line which ran westward about 500 yards from Troop A's right flank, anchored on the Driniumor. South Force's right flank was now refused and additional protection had been secured for medical, supply, and command post installations at the dropping ground banana patch. Troop C was left isolated behind Japanese lines, and Afua was again released to the enemy. It was not until the night of 21-22 July that the Japanese forward units were able to organize for any sort of attack. During that night, elements of the 124th Infantry received considerable mortar, machine gun, and rifle fire from east of the Driniumor. This fire increased the next morning, and about noon the 3d Battalion, 124th Infantry, was attacked from the west by elements of the 237th Infantry. The first Japanese attack was ". . . finally broken up by a bayonet charge . . ." conducted by elements of the 3d Battalion, 124th Infantry, but other attacks followed as troops of the 1st Battalion, 239th Infantry, tried to move across the Driniumor from the east, striking both the 124th Infantry's unit and part of the 2d Battalion, 169th Infantry. Before dark on the 22d, the 3d Battalion, 124th Infantry, counted 155 new Japanese dead in its area. That unit and the 2d Battalion, 169th Infantry, reported their own losses as five killed and twenty-five wounded. The 1st Battalion, 239th Regiment made further unsuccessful attempts to reopen the river crossing. By July 25, Adachi decided to send the 41st Division south to assist in the southern effort. After the fall of Afua, Hall ordered Howe’s battalions to leave their East Branch base and reinforce Cunningham’s South Force, arriving at the new line by July 23. With these reinforcements, Cunningham decided early in the afternoon to send Troops A and B to attack west toward Troop C while Howe’s 2nd Battalion pushed southeast toward the isolated troop. Despite being uncoordinated, the infantry successfully moved into Troop C's perimeter from the northwest and helped repel a heavy Japanese attack from the southwest, while the cavalry troops reoccupied Afua and established new defensive positions. However, American attempts to break out on July 24 were unsuccessful due to the Japanese defending all tracks, trails, and ridgelines in the heavily jungled ground northeast of the perimeter. On July 25, Howe’s Companies E and B unexpectedly established contact about 500 yards north of the besieged forces against light resistance, allowing the battered Troop C to withdraw. With Troop C relieved, Howe’s units continued to attack south and west towards the Afua-Palauru trail, successfully pushing the Japanese into the Torricelli Mountains. Many Japanese troops remained positioned in a triangular area bounded by the dropping ground, Afua, and Company G's ridgeline position, where they continued to harass Cunningham’s forces. Rifle fire, intensifying as darkness approached, harassed the rear and right flank of the two battalions, and the Japanese began intermittently to drop light artillery or mortar shells into the banana patch area, where the command posts of South Force, the 112th Cavalry, and the 127th Infantry were now located. Finally, Japanese patrols, coming in from the west, had scouted the banana patch area during the day, action which seemed to presage an enemy attack during the night. To get out of range of the enemy fire and danger of enemy attack, General Cunningham moved the command post installations 500 yards to the north before dark. Additionally, 127th Infantry patrols had found a Japanese map which indicated that the 66th Infantry, 51st Division, was concentrating in the Kwamagnirk area. Indeed, the 66th Infantry, which, with attached units, was at least 1,000 men strong, had crossed the Driniumor on or about 24 July. Bypassing the right flank of South Force, the regiment had moved into the heavily jungled high ground west of the banana patch and dropping ground. In addition, the remnants of the 237th Infantry, probably about 300 men strong, had finally arrived in the Afua area on 25 July and had passed to the control of the Miyake Force. Rear elements of the 20th Division, including additional men from the 26th Field Artillery and engineer units, had also crossed the Driniumor south of Afua. The number of Japanese troops in the South Force area by nightfall on the 26th of July was at least 2,500 and may have been over 3,000. On July 27, the battalion launched a successful southward attack, but ongoing Japanese movements to the west eventually necessitated an American withdrawal, despite other units under Cunningham managing to repel enemy advances. The following day, Cunningham consolidated his positions to bolster defenses in anticipation of potential large-scale Japanese assaults. However, on July 29, efforts by the 1st Squadron and the 2nd Battalion to attack south and west into the Triangle were thwarted by determined Japanese defenders led by Adachi. As a result, only localized patrol actions were conducted on July 30 and 31, as Cunningham devised plans for another offensive into the Triangle. Major combat activity revolved around the withdrawal of Company G, 127th Infantry, from its exposed outpost west of Afua. On the afternoon of the 29th the unit had been driven more than 400 yards east of its original position by Japanese attacks and had established new defenses on high ground about 300 yards west of Afua. On the 30th the company was surrounded and spent all day fighting off a series of small-scale attacks. The next morning it fought its way north to the dropping ground, where it arrived about 1330. Thence, it moved on to the Driniumor and joined the rest of the 2d Battalion, 127th Infantry, which had switched positions with the 3d Battalion. During the period from 13 to 31 July, South Force had suffered almost 1,000 casualties, of which 260 had been incurred by the 112th Cavalry. For the understrength cavalry regiment, this was a casualty rate of over 17 percent. The 2d Battalion, 127th Infantry, had also lost heavily and was in need of rest, reorganization, and re-equipment--needs which had prompted General Cunningham to change the places of the 2d and 3d Battalions, 127th Infantry. South Force casualties were as follows: 106 killed, 386 wounded, 18 missing, and 426 evacuated as a result of disease and sickness. South Force estimated that it had killed over 700 Japanese. By the end of July, with the arrival of most of the 41st Division, Adachi believed he had amassed enough reinforcements near Afua to launch a final offensive. The 238th Regiment, the 41st Mountain Artillery, and the 8th Independent Engineers were across the river in time by the 30th but the 2nd and 3rd Battalions, 239th Regiment, had missed the crossing point on the Driniumor and were lost. Fortunately for the 18th Army, the South Force withdrawals on July 29 and 30 gave the 20th and 41st Divisions time to complete their organization. New orders were issued for the attack to start on August 1, with the 20th Division on the west and the 41st Division on the east. The strength that the 20th Division could muster for the attack was a little over 2000 men. Most of these troops had been without food for some time. They were suffering from starvation, malaria, and skin diseases, and morale was cracking. They were short of both ammunition and weapons. The 41st Division and its attached units, totaling nearly 1750 men by the morning of August 1, were in equally bad shape. Nevertheless, General Adachi was determ…

    Last time we spoke about the fall of Guam and actions in New Guinea. General Shepherd's Marines had secured the Orote Peninsula, while General Turnage's Marines pushed the Japanese northwards. General Bruce's 77th Division prepared for an eastward assault, and engineers attempted, but failed, to build a supply road to Yona. Geiger's offensive began on July 31, with Marines quickly capturing Agaña and advancing despite dense jungle and resistance. The 77th Division faced tough terrain but liberated 2,000 Guamanians. The push north continued, facing logistical challenges and mined roads. By August 7th, coordinated attacks cleared key areas, culminating in the defeat of remaining Japanese forces by August 11. Guam was back in American hands although scattered Japanese forces continued guerrilla warfare until the war's conclusion. Thus the Marianas campaign had finally come to a conclusion, and now the allies were adding more bass of operation to hit the Japanese home islands. This episode is the Fall of Myitkyina Welcome to the Pacific War Podcast Week by Week, 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 world war two?

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. This week we are diving back over to the northern Burma front. Despite holding Myitkyina through a rainy, muddy summer-long siege, by late July, the Japanese had been gradually cornered into a small perimeter, cut off from all supply lines and running short on ammunition. The situation worsened due to a leadership crisis, between the two Japanese leaders was a matter of semantics. Colonel Maruyama of the 114th Regiment who was in charge of the defense of the city, interpreted his orders to “facilitate the future operations of 33rd Army ‘by securing the vital areas in the vicinity of Myitkyina’,” as a call to defend the city street-by-street, house-by-house. When General Minakami of the 56th Division arrived, he pointed out that all Maruyama had to do to satisfy his orders was simply to continue to deny the Allies access to the Ledo-Kamaing road. Minakami thus found himself in a rather difficult position in regard to the command of the Myitkyina Garrison. Maruyama had conducted an excellent defense, was fully familiar with the situation and, because of his position as former commander, exercised considerable authority. Shortly after Minakami’s assumption of command, General Honda asked how long Myitkyina could stand. Minakami replied that the garrison might be able to hold out for as long as two months. A few days later, Honda was surprised to receive a second message stating, "The Myitkyina Garrison finds it difficult to hold with the poor defense facilities and meager supplies of ammunition." The Army staff concluded that the first message was undoubtedly Minakami's personal opinion as it reflected his determined character and that the second message incorporated the views of Maruyama who was more cognizant of the actual situation. In order that there should be no doubt as to the importance of holding Myitkyina, Honda sent the following message, "Maj. Gen. Minakami will defend Myitkyina to the death” — a message sent with deep regret and sadness according to the staff officers who wrote and dispatched the order. Heavy casualties had reduced the Japanese forces from around 3,000 to fewer than 1,500, further weakening the garrison's defensive capabilities. This number included the heavily wounded and hospital patients, who could only be evacuated by drifting down the Irrawaddy River on rafts, often intercepted by the unforgiving Kachin Levies. On July 24, eight rafts and a boat laden with Japanese were attacked on the Irrawaddy by Kachins of the OSS Detachment 101. Twenty-four Japanese were killed, two captured, and then it was learned these were hospital patients fleeing Myitkyina. Three more Japanese seized by friendly Burmans revealed that hospital patients were being evacuated by the simple expedient of letting them drift down the river on rafts. As these fierce defenders began to falter, General Wessels felt ready to launch his final push. Reinforced by the 149th and 90th Regiments, the American-Chinese forces made daily gains of several hundred yards during the last days of July, though at a significant cost. As the Japanese-held area shrank, counterattacks became less dynamic, captured positions were less fortified, and many Japanese dead were found to be severely wounded men returned to the line. Unbeknownst to the Americans, the desperate defenders had requested a withdrawal to the east by the end of the month. Though Minakami had intended to fight to the last, he ultimately agreed to preserve his men’s lives. On the night of August 1, the Japanese began their escape, crossing the Irrawaddy east of the town. Weighing the many evidences that control of the situation was rapidly passing into their hands, Wessels and his colleagues drafted a new plan of attack. It included an ingenious device, credited to General Pan Yu-kun of the 50th Division. A raiding party, formed into fifteen heavily armed sections, was organized and briefed on infiltrating Japanese lines facing the 50th Division. Having made its way through the Japanese lines in darkness, it was to remain hidden until 0430 when the 50th would assault while the raiders spread confusion behind the Japanese lines. Meanwhile, air reconnaissance revealed many rafts moored against the Irrawaddy within the Japanese lines. "At 0300 hours (3 August), when the moon went down and rain and thunder set in, the raiding party of the 50th Division moved out. The approach was detected only once and some shots were fired at the raiders, who hit the ground. The Chinese did not return fire however, and after laying low for a while, moved out again quietly and cautiously." While the raiders created confusion behind Japanese lines, the 50th Division launched a full attack, quickly overwhelming the remaining enemy positions and capturing 187 prisoners, thus securing Myitkyina for the Chinese. However, about 800 Japanese managed to escape eastward and later rejoined their allies. Minakami was not among them. As the 3rd of August meandered on in a haze of gunfire, blood and rain, Minakami went to sit with his back against a tree. There came the sound of a pistol shot. Japanese officers nearby sprinted to the scene. The general’s orderly was in tears. They found Minakami’s body erect against the tree trunk, facing northeast, towards Japan. The ten-week siege resulted in approximately 3,000 Japanese killed or captured; 972 Chinese killed, 3,184 wounded, and 188 evacuated due to illness; and 272 Americans killed, 955 wounded, and 980 evacuated sick. Overall, the total American-Chinese casualties in 1944 amounted to 13,618 Chinese and 1,327 American casualties. A week later, the Galahad Unit, reduced to only 130 combat-effective men from the original 2,997, was disbanded. The fall of Myitkyina was General Stilwell’s greatest victory, earning him a promotion to full general on August 1, two days before the city fell. The attack was costly in terms of suffering and losses, but the Mogaung-Myitkyina area was a significant prize. It allowed Ledo Road builders and American transport planes to move to Myitkyina and enabled ground forces to link up with other Chinese forces in neighboring Yunnan. As the fighting moved further south down the Hukawng and Mogaung valleys, it became safer for transports to use the lower, more southerly routes to China. This, in turn, increased Hump deliveries to China from 13,686 tons in May to 18,235 tons in June and 25,454 tons in July. While the Allies celebrated victories in northern Burma, the situation in China was dire as the Ichi-Go offensive resulted in many Chinese casualties. By August 1, General Yokoyama had amassed 110,000 troops around Hengyang, equipped with five heavy artillery pieces, fifty mountain artillery pieces, and 40,000 shells. Conversely, General Fang’s resilient defenders had dwindled to 3,000 exhausted troops, with their defenses largely destroyed. General Xue Yue’s reinforcements had failed to reach Hengyang, leaving the Chinese forces to rely on the 46th Army to launch an attack along the railway. On August 4, Yokoyama initiated his main offensive. The 68th and 116th Divisions launched a significant assault from the south and southwest, while the 58th Division quietly positioned itself near the enemy’s northern defenses. Initially, progress was slow. However, by August 5, Yokoyama’s forces had captured Yoping and School Hill. The next day, the 116th Division secured part of the city's defenses. On August 6, the 58th Division breached the city walls from the north, forcing Fang to redeploy troops to counter this new threat. Intense street fighting broke out on August 7 as the defenders valiantly tried to repel the Japanese attacks. By nightfall, the 68th Division had overrun the southern defenses and entered part of the Walled City. Gradually, enemy troops began to surrender, and before dawn on August 8, after 48 days of fierce resistance, Fang was compelled to surrender. Following the capture of Hengyang, Yokoyama declared the successful completion of the initial phase of Operation Togo and promptly began preparations for the subsequent offensive. In this phase, the Japanese reported casualties of over 3860 killed, 8327 wounded, and 7099 sick, with an estimated Chinese casualty count exceeding 100,000, including 8400 killed and 5000 captured in Hengyang alone. To spearhead the next stage of Operation Togo targeting Guilin and Liuzhou, General Okamura Yasuji's 6th Area Army was established on August 25, comprising the 11th, 23rd, and 34th Armies, along with the 27th, 40th, 64th, and 68th Divisions, alongside additional support units. This allowed General Hata to focus on countering potential American landings on the Chinese coast while Okamura directed the offensives in eastern China. Ahead of this operation, Lieutenant-General Tanaka Hisakazu of the 23rd Army initiated a preliminary offensive in late June, positioning the 23rd Independent Mixed Brigade in the northeastern sector of the Luichow Peninsula, advancing the 22nd Independent Mixed Brigade to the Tanjiang River, securing the Jiangmen area with the 22nd Division, and capturing the Qingyuan sector with the 104th Division. By late August, Yokoyama had deployed six divisions along the Shuangfeng-Leiyang line, poised to eliminate the enemy in the district west of Hengyang. On August 29, he launched the offensive, with over 100,000 troops advancing southwest amidst heavy artillery bombardment. Intense ground and aerial combat ensued, resulting in the loss of 10 Japanese planes and 15 enemy aircraft. Despite fierce resistance from Chinese defenders over three days, their entire line collapsed on September 1, prompting a retreat towards Shaoyang, Qiyang, and Jiahe. However, the Japanese advanced relentlessly, covering nearly 100 kilometers in the following days without pause. By September 5, both Qiyang and Huochangpingzhen had fallen, followed by the seizure of Lingling Airdrome on September 8 by the 3rd Division. Progressing along a north-south axis, Japanese forces secured Shaoyang and Changning, while the 58th Division captured Dongan on the same day. With initial objectives achieved, Yokoyama ordered further pursuit, with the 3rd and 54th Divisions converging in the Quanzhou area by September 14. Meanwhile, Tanaka prepared for his offensive, with the bulk of the 104th Division moving towards Taipingzhen, and a raiding unit conducting a wide envelopment maneuver along the Zhukeng-Huaiji road towards Wuzhou by September 6. Subsequently, the 23rd Brigade began its northward march from Suixi. However, Tanaka's offensive wouldn't commence for a couple of weeks. Turning to the broader context of the Pacific War, General Stilwell celebrated a major victory with the fall of Myitkyina, while General Slim's successful defense against Operation U-Go further bolstered Allied morale in the CBI Theater. In Thailand, Prime Minister Phibun's regime faced a significant crisis as Japan struggled to meet the country's essential import needs, leading to inflation, rationing, shortages, black markets, smuggling, corruption, and profiteering. The anti-Japanese Free Thai underground movement, spearheaded by Regent Pridi Banomyong, infiltrated the government, stoking public discontent against both the Japanese occupiers and Phibun's administration. As a result, following the downfall of the Tojo government, Phibun found himself compelled to step down in late July. For his part, Phibun also was thinking of ways, he claims, to prepare to turn against the Japanese. Part of these preparations included proposals to move the capital to remote Phetchabun, north of Bangkok, and construct a “Buddhist City,” a sort of center for world Buddhism, near Saraburi—both grandiose projects in typically extravagant Phibun style. Moving to the isolated, mountain-ringed Phetchabun, Phibun later argued, would facilitate a Thai uprising against the Japanese. Yet on July 18, the Tojo government in Japan resigned, and only six days later the Thai National Assembly turned down both government bills and forced the resignation of Phibun as prime minister. The deputies in the assembly voted against these plans motivated in part by the fall of Tojo, who was closely associated in their minds with Phibun, in part by their feeling that the war was turning against Japan, and in part by their feeling that Phibun was too closely identified with an authoritarian past that must now be buried for the sake of improving relations with the Allies. Politician Khuang Aphaiwong then assumed his position as Prime Minister on August 1. Serving as a compromise candidate, he navigated between Phibun's supporters and the opposition while maintaining cooperation with the Japanese and safeguarding Free Thai members who had collaborated with the Allies. Meanwhile, in China, the success of Operation Ichi-Go led to another leadership crisis. Despite the initial rejection of Stilwell commanding troops in China in 1942, the effective Japanese offensive posed a threat of defeat to the Chinese Government, reigniting the debate over command authority. This was especially significant as Chinese troops under Stilwell’s command were achieving significant victories in northern Burma. However, Stilwell's vocal criticism of Chiang Kai-Shek’s corrupt regime and incompetent generals strained their relationship. Chiang favored General Chennault, who proposed that with a monthly allocation of 10,000 tons for operations in northern China, his 14th Air Force could halt the Japanese offensive. Despite his strained relationship with Chennault, Stilwell redirected Hump allocations to increase the 14th Air Force's allocation to 8,425 tons, although he couldn't secure an additional 1,500 tons from the Matterhorn allocation. Chennault's aircraft managed to disrupt the Japanese advance, but failed to halt it completely. In late June, Stilwell faced criticism when Vice-President Henry Wallace visited Chongqing. While Wallace persuaded Chiang to allow a small American observer mission into Communist territory, he also recommended Stilwell's recall due to hi…

    Last time we spoke about fall of Tinian and battle of Sansapor. Following the capture of Noemfoor and Biak, the Allies advanced to the Vogelkop Peninsula, constructing vital airbases. MacArthur initially focused on seizing Sorong and Waigeo Island, but operations accelerated, making Klamono oilfields non-viable, and oil rehabilitation projects in the Dutch East Indies were prioritized by the Joint Chiefs of Staff. MacArthur planned reconnaissance in the Mar-Sansapor area. The 6th Division launched Operation Typhoon, and Task Force 77 executed landings on July 30, 1944. Airfields were built, and patrols eliminated Japanese forces. Meanwhile, Tinian saw intense fighting, with Marines securing key objectives by July 31. Following massive bombardments, Marines continued advancing, encountering heavy resistance but eventually declaring Tinian secure on August 1. Guam operations saw similar advances with coordinated attacks overcoming Japanese defenses.

This weeks podcast brings us back into the intense action in Guam. As we previously observed in Guam, General Shepherd’s Marine brigade had effectively captured the Orote Peninsula, while General Turnage’s 3rd Marine Division had reached the designated beachhead line, pushing back a weakened Japanese force retreating northward. Meanwhile, General Bruce’s 77th Division maintained control of the southern beachhead line, preparing for a general eastward assault. An engineer battalion began constructing a supply road towards Yona, a project that ultimately failed to support the infantry's advance. On July 30, Turnage’s Marines and the infantrymen sent patrols to gauge the strength of the Japanese forces, but dense foliage obscured enemy movements. Geiger eventually concluded that defensive positions were likely near the Agaña-Pago Bay Road. He planned an initial advance toward the general line of Agaña-Famja-Pago Bay, followed by a northeastward attack. Turnage’s Marines were assigned to capture the capital, Agaña, and the strategic Tiyan Airfield on the left, while Bruce’s infantry aimed to secure the Pago Bay area on the right. Following two days of intense artillery and naval bombardment, Geiger’s offensive commenced at 06:30 on July 31. On the left, Turnage’s units encountered minimal resistance. The 3rd Marines, now led by Colonel James Stuart, quickly occupied the ruins of the abandoned Agaña and moved beyond the O-1 Line to secure the main northbound roads. The 21st Marines advanced through dense underbrush, reaching O-1 after neutralizing an enemy pillbox near Famja. When Lieutenant Colonel Duplantis 3rd battalion, 21st marines brought his command post forward, a curious incident occurred which illustrated the confusion of the Japanese. Someone in the battalion command group sighted one of the bypassed enemy groups, estimated to be about 15-20, led by an officer, moving toward the new CP area. The Marines held their fire, and when the small unit got to within 150 yards of the waiting men, an interpreter called to the Nipponese to surrender. Apparently thinking they had finally reached friendly lines, they started forward, then stopped to hold a hurried conference. The chattering was interrupted by the interpreter urging them forward, but by this time the aggregation had decided they were in unfriendly territory. They broke and ran in all directions; the Marines opened fire, killing and wounding about half of the intruders. Those still alive escaped into the protecting foliage. The 9th Marines destroyed a delaying detachment at Ordot and two tanks during their successful push to O-1. Colonel Hamilton’s 1st and 3rd Battalions, along with Colonel Tanzola’s 3rd Battalion, advanced to the right, moving through steep slopes and narrow gorges in columns. They successfully reached Yona and the Pago River without encountering any opposition. With the Reconnaissance Troop protecting the south flank, General Bruce's 77th Infantry Division started toward the east coast of Guam at 7:00, 31 July. Elements of the 307th, with 3/305 attached, led the way in a column of battalions. Lack of enemy resistance permitted battalions to move with companies in column; even so, the march proved most difficult. The troops initially scaled steep slopes, slid down into narrow gorges, and followed along the foothills southwest of the central mountain range of Guam. For a time, vehicles followed, but soon the terrain became so rough that even jeeps could not traverse it. As one infantryman later wrote: “The distance across the island is not far, as the crow flies, but unluckily we can't fly. The nearest I came to flying was while descending the slippery side of a mountain in a sitting position. . . . After advancing a few yards you find that the [bolt] handle of the machine gun on your shoulder, your pack and shovel, canteens, knife, and machete all stick out at right angles and are as tenacious in their grip on the surrounding underbrush as a dozen grappling hooks. . . . The flies and mosquitos have discovered your route of march and have called up all the reinforcements including the underfed and undernourished who regard us as nothing but walking blood banks. We continue to push on. . . .” During this movement, Hamilton’s Company L liberated 2,000 Guamanians from a concentration camp near Asinan. Soldiers willingly gave their rations and cigarettes to the undernourished men and women who were almost overcome with joy at once again seeing Americans. Men of the 77th Division soon forgot the long, tiresome cross-island march as the full realization of the expression, "liberation of enslaved peoples," came to the troops. Following the Orote operations, Shepherd’s brigade was ordered to take over the southern half of the beachhead line from Inalas to Magpo Point, relieving the 305th and 306th Regiments. On August 1, Geiger’s northward push continued, with the 305th moving to the Yona area and the 306th heading to Pago Bay. The 305th and 307th Regiments advanced slowly through rough terrain without opposition, reaching the O-2 Line by nightfall. On the left, Turnage began his advance with three regiments abreast, but the 3rd and 9th Marines eventually pinched out the 21st upon reaching the intermediate D-2A Line. At 15:00, these two regiments resumed their advance against slight resistance and reached O-2 by nightfall. The main challenge during this period was moving supplies forward, as both divisions relied on the same coastal road, heavily mined by the Japanese. With the rapid advance came the necessity to move supply distribution points closer to the front. Trucks began to roll over the already crowded coast highway to establish an advanced division dump in the Agaña Central Plaza area. Artillery units started to displace forward so that continuous direct support would be available to the assault units. This added traffic, plus the fact that the 77th Division would have to move supplies over the same road, presented a problem to the engineers. In an effort to alleviate the situation, the 25th Naval Construction Battalion and the 19th Marines put all available men to work improving existing roads and trails. Yet despite these efforts, by August 1, the problem of getting supplies forward was becoming more serious. The main coast road –and only one that ran from west to east on northern Guam– over which all traffic had to move had been heavily mined. The Japanese had placed aerial bombs and single-horned mines at road junctions and intersections in and around Agaña. In addition to being mined and heavily congested, the two-lane, hard-surfaced Agaña-Pago Bay Road was overused, poorly maintained and, with frequent rain, soon deteriorated badly. In the end, the engineers could not properly maintain the road and still allow the essential supply convoys through. On the morning of August 2, artillery and warships bombed the new positions General Obata was trying to establish around Mount Santa Rosa. Meanwhile, the Marines and infantrymen continued their pursuit northwards, aiming to reach the O-3 Line behind Japanese delaying positions at Finegayan and Mount Barrigada. On the left, the 9th Marines swiftly captured Tiyan Airfield, but their advance was hampered by dense jungle. Despite this, they managed to gain 1800 yards while the 21st Marines cleared the Saupon Point-Ypao Point area of small enemy groups. On the right, the 77th Division's advance was initially covered by a 14-tank patrol conducting reconnaissance in the Barrigada area, where they faced heavy resistance. The 307th Regiment quickly secured Price Road, but Tanzola’s 3rd Battalion was halted by concealed machine-gun positions near Barrigada Well. Subsequently, the 307th, now led by Lieutenant-Colonel Thomas Manuel, was also stopped near the village, with Manuel’s 1st and 3rd Battalions becoming mixed up just as an enemy tank broke through their lines. After numerous failed attempts to dislodge the enemy, Companies G and E managed to penetrate the Japanese lines in the afternoon, although Company G had to be evacuated by nightfall. Meanwhile, the 305th moved up and consolidated its lines with the 307th. Since Bruce’s infantrymen failed to link up with the Marines, Colonel Butler’s 2nd Battalion was sent to fill the gap between the divisions. Following a reorganization, the 305th and 307th Regiments attacked again the next morning, encountering surprisingly little resistance as they moved through Barrigada and secured the vital well. The 77th Division had a special reason for wanting to reach Barrigada quickly. The reservoir and pump, located 100 yards northwest of Road Junction 306, could supply 20000 gallons of water daily to the troops. Until now, the men of the division had quenched their thirst by getting water from streams and creeks. But in the northern part of Guam there were no streams, and the reservoir would be the only source of supply. With tanks leading the way, Manuel’s 3rd Battalion advanced quickly and reached the summit of Mount Barrigada, although the 2nd Battalion lagged behind. Meanwhile, the 305th Regiment engaged in several isolated skirmishes but still managed to link up with the 307th. To the left, Turnage had also resumed his advance toward O-3. Although the 3rd Marines encountered little resistance and reached their objective successfully, Colonel Craig’s 1st Battalion was halted by heavy fire near Finegayan after destroying a Japanese stronghold. That night, the Marines faced mortar and tank attacks, but these assaults made little progress. Meanwhile, as the 22nd Marines patrolled southern Guam, the 4th Regiment was held in reserve at Toto. On August 4, the remainder of Shepherd’s brigade began moving to Toto, leaving only Colonel Schneider’s 1st Battalion and the 6th Defense Battalion behind. Following Turnage’s orders, the 21st Marines were positioned between the other two regiments to reach O-3 near Dededo. At the same time, Craig’s 1st Battalion made minimal gains toward Finegayan, while the rest of the 9th Marines advanced to O-3 and successfully severed the Finegayan-Barrigada Road. To the right, Bruce’s infantrymen, following an artillery barrage, advanced to O-3, overcoming terrain difficulties and securing the objective line by nightfall. On August 5, Turnage’s three regiments continued their advance, pushing past O-3. The 3rd Marines reached Amantes Point, and Craig’s 1st Battalion finally overran the remaining Japanese positions at Finegayan. Behind them, Shepherd’s brigade moved to Dededo, preparing to take over the left flank for the final push. Meanwhile, as the 306th Regiment relieved the exhausted 307th, Tanzola’s men continued to fight through the dense jungle, with his 2nd Battalion reaching the O-4 Line by nightfall. During a nighttime raid, the 1st Battalion was targeted, resulting in 48 casualties. Following this, the 2nd Battalion encountered the tanks the next morning, eventually neutralizing them but suffering an additional 46 casualties. Bruce’s regiments gathered at O-4 to prepare for an attack on Mount Santa Rosa, where Obata had concentrated his forces. Turnage’s regiments also resumed their attack, advancing with minimal resistance. Geiger initiated the final push on August 7, with Turnage’s Marines facing minor obstacles due to jungle terrain. Despite this, the 3rd Marine Division reached the O-5 Line by nightfall. Shepherd’s brigade swiftly progressed along the coast, joining forces with the 3rd Marines. Meanwhile, the 306th and 307th Regiments prepared for a coordinated attack. Bruce's strategy involved the 306th securing ground north of the Japanese defensive lines, the 307th leading a tank-infantry assault on Yigo, and the 305th closing in on Mount Santa Rosa. Once each objective was secured, Santa Rosa would be encircled from Anao to Lumuna Point, leaving the enemy with no escape route except into the sea. By midday, despite facing delays from the narrow road and enemy sniper activity, Manuel's tanks surged ahead of the infantry, veering right to swiftly eliminate several Japanese machine-gun positions at the road's edge. However, their advance was halted by heavy Japanese fire from the left rear as they crested a slight elevation. In a wedge formation, commanded by Captain Seger from his tank at the right rear, the light tanks swept rapidly over the slight crest. As they pushed on there was an explosion to the left of the tanks directly in front of Seger. He radioed to Colonel Stokes: "There's a burst in front of me; could be mine or antitank gun. Call for the mediums." Just before the mediums came up more explosions sounded from the left. The tankers could not locate the source of the fire because of the dense woods to the left and the absence of flash and smoke. When the mediums reached the open area, their crews could tell that the light tanks were in trouble but they could not see where the fire was coming from. Only when they advanced up the slight rise and began themselves to have steel shrapnel and bullets smash on the left of their hulls and turrets did they turn and pour fire back into the woods at the left rear. Fifty yards behind the stricken tanks the infantrymen struggled to push through the positions by the road that the tanks had overrun. Japanese still fired from a pillbox that had been blasted by the medium tanks as they raced ahead. The troops put rifle and machine-gun fire into it. They threw six grenades before one landed inside the position. The enemy continued to fire from it. A flame-thrower man maneuvered cautiously up to the position and put the searing flame in through an opening. The heat was too much for the defenders; one of them scurried out and fell before the American guns. The enemy position, so skillfully concealed from the front but vulnerable from the rear, was built around two light tanks. Two antitank guns, two 20mm guns, six light and two heavy machine guns, plus about a makeshift battalion of infantry added their fire to make the Yigo defense formidable. One medium was hit in its gas tank. Flames shot out of the bottom and quickly enveloped the sides. The crew hast…
