- 141 - Pacific War Podcast - Battle of Sansapor July 30 - August 5, 1944

Last time we spoke about invasion of Guam and Tinian. Japanese forces, led by General Obata on Guam and Colonel Ogata on Tinian, prepared defenses with trenches, pillboxes, and artillery. The Americans bombarded these defenses extensively. Despite resistance, they successfully landed on Guam and Tinian, securing beachheads. Intense fighting ensued, with Marines facing heavy casualties. Despite Japanese counterattacks, American forces gradually expanded their footholds, leading to the eventual containment of the Japanese on Orote Peninsula. The Japanese launched a fierce assault against Marine positions on Guam, engaging in close combat with heavy casualties on both sides. Despite initial success, the Japanese offensive was repelled by intense artillery and machine-gun fire, leaving the remaining enemy forces to defend Orote Peninsula. On Tinian, after extensive naval bombardment, Marines landed successfully, repelling Japanese counterattacks and establishing a beachhead. Despite heavy Japanese casualties, the Marines suffered relatively few losses, ultimately breaking the enemy's resistance.

Initially considering Manokwari as a non-critical objective, MacArthur's plan centered on seizing Sorong and Waigeo Island for crucial supply and air bases in New Guinea. However, the rapid pace of Pacific theater operations raised doubts about the feasibility of bringing the Klamono oilfields into production before the war's end, prompting the cancellation of exploitation plans by the Joint Chiefs of Staff.  The Joint Chiefs assumed responsibility for the direction and coordination of oil rehabilitation projects in the Dutch East Indies and undertook necessary liaison with British and Dutch agencies. By mid-February 1943 they had decided that military units would at least start all oil rehabilitation and exploitation projects in the Indies, although the final development of the oil resources might be left to civilian agencies. MacArthur was instructed to plan the location and timing details of oil rehabilitation projects in the Indies, and, subject to the Joint Chiefs' approval, execute those plans. At the same time, the Joint Chiefs directed that the organization of special military petroleum production and refining units begin. The requisite troops, most of them US Army engineers and many especially recruited from civilian pursuits, soon began to assemble and train in California. Orders were also placed with manufacturers for the special production and refining equipment, which was sent to California as it was obtained. While these steps were being taken to coordinate oil rehabilitation projects, it had become obvious that in accordance with MacArthur's plans the first significant oil producing region that could be recaptured in the Netherlands East Indies would be the Klamono district on the Vogelkop Peninsula.
