Last time we spoke about beginning of the bombing campaign against Japan. The Japanese 11th Army faced setbacks at Hengyang due to resilient Chinese defenses and supply shortages. Reinforced by General Xue Yue, Chinese forces launched effective counterattacks, regaining some territories before being pushed back. By July 20, the Japanese resumed their offensive but faced heavy resistance and were paused. American air raids on Japan and Manchuria intensified under General Arnold’s orders, despite logistical challenges. In Burma, Allied forces under General Stilwell made slow but steady advances, capturing strategic positions and repelling Japanese counterattacks. The Chindits, severely depleted, were eventually evacuated. In Yunnan, Chinese forces encircled and assaulted Japanese positions, achieving significant gains despite heavy resistance and logistical issues.

Today our week begins with the ongoings of Operation Forager. By late July, American plans for the invasions of Guam and Tinian were finalized. General Cates’ 4th Marine Division was assigned to land on Tinian’s White Beaches, while General Geiger’s 3rd Amphibious Corps planned two amphibious landings nearly seven miles apart to trap the Japanese in a double envelopment. General Obata, who had relocated his headquarters to Guam, commanded several troops on these islands. On Tinian, Colonel Ogata Keiji's forces included the 50th Regiment, the 1st Battalion of the 135th Regiment, the tank company of the 18th Regiment, and the 56th Naval Guard Unit, totaling 8,039 men. Similar to Saipan, he divided Tinian into three sectors, with most troops defending Tinian Town and Asiga Bay. The 1st Battalion of the 135th Regiment, supported by Ogata’s artillery, formed the Mobile Counterattack Force, ready to respond swiftly to landings. This left only Ogata’s 3rd Company to defend the northwest coast where the Americans planned to land.
Meanwhile, General Takashina’s 29th Division was assigned to Guam and reinforced by Major-General Shigematsu Kiyoshi’s 48th Independent Mixed Brigade and Colonel Kataoka Ichiro’s 10th Independent Mixed Regiment. Takashina’s units fortified the landward neck of the Orote Peninsula and established strong positions on the beaches of Agat, Asan, Tumon, and Agaña Bays. The main fortified area ran along the west coast from Tumon Bay to Facpi Point and included, of course, Orote Peninsula. Other fortified beaches, on the south and east coasts from Merizo to Pago Bay, had been abandoned before W Day, their defenders having moved to the north. Outside the main fortified area, the airfields were provided local defense by anti-aircraft and dual-purpose guns. The most notable and certainly the most effective fortifications on the island were constructed across the neck of Orote Peninsula, which contained a fairly elaborate system of trenches and foxholes arranged in depth, together with large numbers of pillboxes and heavy-caliber weapons. Outside of Orote, the prepared defenses were generally hastily constructed and often incomplete. The typical beach defense was arranged, from the seaward side, in four parallel lines: first were obstac
