- 181 - Pacific War Podcast - the Second Okinawa Offensive - May 6 - 13, 1945

Last time we spoke about the Allied invasion of Borneo. The Allies initiated the invasion of Borneo, commanded by General Morshead. The operation, known as Operation Oboe, aimed to reclaim vital oilfields from the demoralized Japanese forces. Despite their fierce resistance, American troops swiftly captured strategic locations on the island. The Japanese, already struggling with low morale and supply shortages, were unable to mount an effective defense. Amid the intense fighting, Air Commodore Cobby’s forces conducted air assaults on key targets, weakening Japanese positions. As American troops landed on Tarakan Island on May 1, they faced heavy fire but managed to gain significant territory by nightfall. By early May, despite the loss of ground, Japanese forces continued to resist fiercely. This victory in Borneo marked a turning point in the Pacific campaign, ultimately foreshadowing the decline of Japanese influence in the region and paving the way for further Allied advances.

Last we left off, by April 24, General Ushijima's 32nd Army had chosen to abandon the first line of Shuri defenses, with the exception of the extreme right in the Item Pocket area. However, the weary Japanese troops merely withdrew to the next line of prepared positions within the Shuri defense zone, ready to make the American invaders pay for every inch of territory gained. Observing this, General Hodge promptly ordered the 7th, 27th, and 96th Divisions to regroup and enhance their positions through aggressive maneuvers, seizing strategic ground in front of them and pushing back enemy outposts. His forces were also heavily depleted and exhausted, prompting him to plan a final offensive on April 26 before rotating in the relatively fresh 77th Division and the 1st Marine Division for support. Unbeknownst to him, the 62nd Division had suffered significant losses, nearly losing half of its original strength on the left flank. In response, Ushijima decided to move the 24th Division and the 44th Independent Mixed Brigade north to reinforce the Shuri defense zone, establishing a fallback position for retreating forces.This shift also meant that the southern areas were defended only by a hastily assembled Shimajiri Security Force of 5,500 men, drawn from rear-area supply units tasked with delaying any American advances from the south until the main infantry units could return. 

The question of a second landing in southern Okinawa was considered by 10th Army most seriously before April 22. General Bruce, commander of the 77th Division, knew that his division would be committed in the Okinawa fighting as soon as lejima was secured. At Leyte the amphibious landing of the 77th Division behind the Japanese line at Ormoc had been spectacularly successful. General Bruce and his staff wished to repeat the move on Okinawa and urged it on the 10th Army command even before the division sailed from Leyte. As the Iejima fighting drew to a close, General Bruce pressed his recommendation to land his division on the southeast coast of Okinawa on the beaches just north of Minatoga. He believed that it would be necessary to effect a juncture with American forces then north of Shuri within ten days if the venture was to be successful. His plan was either to drive inland on Iwa, a road and communications center at the southern end of the island, or to push north against Yonabaru. General Buckner rejected the idea. His assistant chief of staff, G-4, stated that he could supply food but not ammunition for such a project at that time. The Minatoga beaches had been thoroughly considered in the planning for the initial landings and had been rejected because of the impossibility of furnishing adequate logistical support for even one division. The reefs were dangerous, the beaches inadequate, and the area exposed to strong enemy attack. Although beach outlets existed, they were commanded both by the escarpment to the west and by the plateau of the Chinen Peninsula. The 10th Army intelligence officer reported that the Japanese still had their reserves stationed in the south. Both the 24th Division and the 44th Independent Mixe
