Last time we spoke about operation forager and the Changsha-Hengyang campaign. On Saipan, General Holland Smith's forces advanced with the 4th Marine Division targeting Hill 600 and the 2nd Marine Division capturing Mounts Tipo Pale and Tapotchau. The 27th Division supported these efforts, encountering resistance and challenging terrain. Meanwhile, the 27th Division, under new leadership, made progress despite difficulties. Concurrently, Japanese forces initiated a three-pronged assault in Hunan, capturing significant territory despite supply challenges and heavy rain. On June 11, the 40th Division took control of Yiyang while the 34th Division moved toward Yuelu Mountain. The 68th and 116th bypassed Changsha towards Guanqiao, with the 3rd and 13th facing resistance near Liuyang, which fell on June 14. Xue Yue retreated to Liling as Chinese defenses crumbled. Concurrently, the U.S. initiated Operation Matterhorn, targeting Japan's industrial sites. Despite challenges, the initial bombing runs prompted further strategic bombings, marking a significant phase in the Pacific War.

As we last saw, the Americans had begun their advance into Central Saipan. They achieved significant success on the right with the 4th Marine Division, but faced difficulties breaking through on the left and center. Following the victory in the Philippine Sea, Admiral Turner successfully completed unloading operations, landing approximately 60,000 troops and 75,000 tons of supplies by June 26. To maintain air superiority, Admiral Mitscher conducted raids on the islands of Pagan, Tinian, Guam, Rota, and Iwo Jima, and continued these raids over the next few days, despite ongoing Japanese night air attacks against the American beachhead. In a strategic effort to keep the Japanese unsettled and unable to prepare for counterattacks, Carrier Task Group One raided Pagan Island on June 23rd. The neighboring islands in the Marianas were also not ignored; almost daily photo reconnaissance missions were conducted over Guam and Tinian to monitor any changes in their situation or positions before the landings. On June 25, Carrier Task Group Three carried out intense bombing raids on Guam and Rota to further incapacitate the airfields and installations there. The first significant naval raid following the battle, beyond routine operations, was an attempted strike against the Volcano-Bonin group, which escalated into a substantial air battle initiated by the Japanese. At 6:00 on June 24th, Vice Admiral Joseph J. Clark's Task Group 58.1, comprising the Hornet, Yorktown, and Bataan launched a long-range fighter sweep of 48 Hellcats against Iwo Jima, which was intercepted by numerous enemy fighters. In the ensuing battle, four U.S. Hellcats were lost, while Japanese losses were estimated at 68 fighters and bombers. Despite this defeat, the Japanese attempted another attack against Clark's task group with the remnants of their local air force. This attempt ended disastrously for them, as U.S. interceptors shot down an additional 46 aircraft, bringing the day's total to 114. Task Group 58.1, having completed its mission without bombing the airfields, safely returned to Eniwetok without incident. On the opposing side, after the fall of Mount Tapotchau, General Saito organized a final line of resistance between Tanapag, Radar Hill, and Tarahoho. In a brief resume on the morning of 27th June, Major General Igeta summarized the situation: “The summit of Tapotchau was occupied yesterday evening. Front line units tried to retake it with a night attack, but did not succeed as planned. In Donnay the enemy broke through with a number of tanks, but their advance was slow. Thereafter, no great change in the situation. The defense force, along with the firmest possible defense of its present front line and its activities toward annihilation of the enemy, is at present setting up with a line between Tanapag--Hill 221 (Radar Hill)--Tarahoho as the final line of resistance… Meanwhile, about 50 men of the 118th Infantry are improving their positions on the east side of Hill 343, and one company of the 136th Infantry is improving its position on Hill 268, and about 50 men of the 118 Infantry are digging in on the north side of that hill. The main body of the 9th Expeditionary Force, about 200 men, and about 100 men from the 9th Tank Regiment are consolidating their positions north and east of there in the high ground (Chacha water area).”Although the pre-landing preparations had been largely ineffective, continuous naval bombardment during the battle forced his troops to stay low and defend under intense pressure. For the June 27 attack, General Smith ordered the three divisions to advance side by side and capture the O-6 Line. On General Schmidt’s front, progress was swift. The 23rd Marines advanced quickly, facing only sporadic rifle fire from the villages of Donnay and Hashigoru, and reached their objective. Meanwhile, the 165th Regiment moved rapidly through the hills but struggled to maintain contact, requiring the deployment of a battalion from the 24th Marines to fill the gap and repel an enemy tank attack. In the center, the 106th Regiment encircled Hell’s Pocket and established a cordon at the north end of Death Valley, although they made little progress against Hill Able. To the left, General Watson’s Marines advanced about 200 yards along Mount Tapotchau's western slopes while the division realigned its lines. Despite largely ineffective pre-landing preparations, the continuous naval bombardment during the battle forced enemy troops to stay under cover and defend under intense pressure. In General Saito’s words “The practical experiences of the defense forces of Saipan… have to do with the power of the enemy naval bombardment. If there just were no naval gunfire, we feel with determination that we could fight it out with the enemy in a decisive battle.” Underwater mines, which the Japanese had used as land mines, were found along the road and railroad in the vicinity of Donnay. Tanks detoured these mined areas without difficulty, however. A Japanese supply dump, found near Hashigoru, contained new clothing, ammunition, and infantry weapons. Lieutenant Colonel Dillon's 2nd Battalion, moving through the matted vegetation and ragged cliff line along the coast, experienced difficulty keeping abreast of the faster-moving 3d Battalion. Since a detailed search of the gnarled coast line could not be instituted without sacrificing the momentum of the attack, Colonel Jones ordered the 1st Battalion to follow Dillon's unit at 400 yards, mopping up and investigating suspicious areas. By 4:40pm the 23rd Marines had trudged to objective O-6. Both battalions immediately dispatched security-reconnaissance patrols to their front but made no contacts with the enemy. The next day, Major-General George Griner arrived to assume command of the 27th Division, immediately reorganizing his units and deploying the reserve 3rd Battalion, 105th Regiment. The 3rd Battalion, 106th Regiment had suffered heavy casualties in its Death Valley fight. By June 28 its effective strength of riflemen numbered approximately 100, and it was reorganized into a single rifle company. Among the 3rd Battalion's casualties on June 28 was the commanding officer, Lieutenant Colonel Harold I. Mizony, USA, killed in action when two Japanese tanks unexpectedly appeared just forward of his battalion observation post. By chance, the two enemy vehicles had found a lucrative target; commanders of the 2nd and 3rd Battalions, together with their company commanders, were gathered to plan the next move. Tightly grouped a short distance behind them were the men of the two battalions, waiting for the orders that would send them into action. Within a matter of moments the enemy tankers reaped an awful harvest, including 12 killed and 61 wounded, and then disappeared unscathed. On General Watson’s front, Major Hunt's 2nd Battalion continued to fight across the open canefield toward its objective, a low ridge line north of Tipo Pale. Japanese riflemen and machine gunners, secure in their hillside grotto, raked the clearing with grazing fire. Light flame-thrower and medium tanks were available to the 6th Marines, but their use in this instance was limited because of difficult routes of approach to enemy positions, and support had to be delivered from long ranges. This left the task to the infantrymen. As everywhere demonstrated, reduction of cave positions proved a slow, painful job. By late afternoon the situation had improved slightly and the volume of Japanese fire had diminished somewhat, but the 2nd Battalion's unceasing efforts since 6:30 found it still short of the ridge line objective and very tired. A great store of energy had been burned in moving across the murderous field, yet more effort would be required. It appeared that the Japanese were rooted to the pock-marked ridge line. The Tipo Pale strong point, at which Company K, 6th Marines, had been whittling for many days, finally was secured on 28 June, permitting the company to rejoin its battalion. The tenacious Japanese soldiers in this pocket had sold their lives but had exacted from the 6th Marines a high price in time, men and effort. The 8th Marines encountered tough Japanese resistance and difficult terrain while advancing against four small hills known as the Pimples, achieving minimal progress. Meanwhile, Schmidt, positioned well behind the 27th Division, received orders to maintain current positions. However, the 23rd Regiment conducted patrols beyond its lines up to 500 yards, and the 165th Regiment secured Hill 700 to complete the movement to the O-6 Line. Over the following two days, combat fatigue and the need for the 27th Division to catch up slowed the Marine divisions almost to a halt. Beginning their attack at 11:00 on June 29, the 3rd Battalion, 105th Regiment successfully closed the gap on Griner’s right flank by about 800 yards, eventually linking up with the 24th Marines the next day. On the left, the 106th Regiment encountered heavy resistance but eventually captured Death Valley and Hell’s Pocket, establishing contact with the 8th Marines by June 30. Behind them, the 2nd Battalion, 165th Regiment secured Hill Able and the remaining portion of Purple Heart Ridge. Meanwhile, the Marines and the 165th Regiment conducted patrols, cleared out remaining enemy forces, and fortified their positions. The 6th and 8th Marines also made some limited progress northward, culminating in the capture of Bill’s Pimple. During the night of June 30, the Japanese commenced their withdrawal towards Saito’s final defensive line in an organized manner despite facing artillery fire. This new defensive line, though shorter, provided an opportunity for Saito to regroup his troops and strengthen their defense. However, failure to hold this position would spell disaster for him and his soldiers. Upon learning of the Japanese retreat, the American forces resumed their offensive on July 1, encountering stubborn resistance from remaining Japanese pockets that needed to be cleared out. The following day, General Smith's forces launched a coordinated attack. On the left flank, Colonel Stuart’s 2nd Marines swiftly advanced through Garapan, Flametree, and Sugarloaf Hills, while the 6th Marines made significant gains after neutralizing an enemy stronghold. The 8th Marines, after securing the Pimples, faced heavy Japanese resistance at Limestone Hill. In the meantime, evacuation of casualties had become a problem: Marines had fallen on the open field, and all attempts to rescue them only resulted in more men being hit. The scheme finally adopted, and the one which brought success, was for a tank to position itself between the casualty and the limestone hill. By following directly behind the tanks, hospital corpsmen could then move safely to the wounded, apply hasty bandages, give them a shot of morphine, and place them on stretchers. Then, carefully coordinating their moves with the tank by talking to the driver through the sound-powered phone on the rear sponson, the stretcher bearers would precede the tank from the site, all the while shielded from Japanese fire. White phosphorous rounds dropped on the hill by the 81mm mortar platoon plus frontal blasts from the chaperoning medium tanks also contributed to the success of this resourceful project. The fact that only small arms fire spattered against the thick hulls of the tanks indicated that the Japanese had no heavier weapons readily available in the limestone hill. By dark, all wounded had been rescued, but the task of seizing the hill still remained. Only a clever night tank raid, utilizing illuminating shells and flamethrower tanks, could eliminate this stubborn Japanese position. In the center, the 106th Regiment advanced despite sporadic fire, while the 105th Regiment had to overcome the Papako strongpoint to make modest gains. With the arrival of the 27th Division at the O-6 Line, the right units could resume their advance. Consequently, the 165th Regiment encountered minimal opposition, advancing 1700 yards, while the 23rd and 24th Marines made virtually unopposed progress to the intermediate O-6A Line. On June 3, the general offensive persisted, now targeting the O-7 Line. On the front under Watson's command, the 2nd Marines successfully took control of the remaining portions of Garapan, though they encountered difficulty clearing Mutcho Point on the town's northwestern edge. Duty in the town had little to commend it; battered skeletons of what had once been buildings, and humans, and animals, dotted the area; the choking smell of death hung about like a fog. And everywhere were the pieces of corrugated iron which the Japanese and natives had used as roofing for almost every structure from the hen house to the bank. To step on one of these huge rattling sheets was to inform everyone thereabouts of one's presence. Garapan's trash and garbage dump appearance was further enhanced by odd clothing, shoes, papers, books, and miscellaneous bric-a-brac strewn through the area. Perhaps the only bright point was the copious wells, providing adequate water for the 2nd Marines to bathe away some of the filth on their bodies. The 6th Marines also advanced, halting 1000 yards from the coast, while the 8th Marines faced minimal resistance and gained approximately 1000 yards. Meanwhile, Schmidt's three regiments advanced side by side and in formation, making swift progress over challenging terrain but were ultimately halted before Hill 721 and 4th of July Hill. Nonetheless, the 24th Marines managed to capture Radar Hill, situated at the center of Saito’s final defensive line. In the central area, Japanese delaying units hindered the 27th Division's progress towards the coast, with the 106th advancing another 1000 yards and the 165th about 500 yards. During the night of July 3rd the 165th Infantry command post became the scene of violent activity when 27 Japanese advanced into the installation, apparently by mistake. All of the Japa…
