- 192 - Pacific War Podcast - Operation Downfall - July 22 - 29, 1945

Last time we spoke about the fall of Wewak. In June 1945, Allied forces, led by General George Stevens, intensified their campaign to capture the strategic town of Wewak in New Guinea. After years of grueling combat, they relentlessly pressed against entrenched Japanese defenses, including the remnants of General Mano's 41st Division. The Australians achieved critical victories by securing vital supply routes and establishing new airfields, facilitating their advance. By May 8, after intense fighting, Australian troops effectively seized Wewak Point, eliminating entrenched Japanese soldiers in bunkers and caves. Despite suffering casualties, the Australians distinguished themselves through bravery and tactical ingenuity. Ultimately, the successful capture of Wewak marked a pivotal moment in the Pacific campaign, showcasing the determination and spirit of the Allies as they pushed towards victory in the Pacific Theater, bringing an end to a crucial chapter of the war.

After the fall of Okinawa, the Allies were mopping up campaigns across the Asia-Pacific and planning for what was assumed to be the most cataclysmic battle yet, the invasion of the Japanese home islands. First we are going to travel back to Luzon. By mid-June, General Krueger’s 6th Army had successfully captured all key objectives in northern Luzon, southern Luzon, and the area east of Manila, which serves as the capital of the Philippines. Although General Yokoyama’s poorly equipped 41st Army had been rapidly scattered and forced into hiding, General Yamashita’s Shobu Group still retained enough strength to continue its resistance in northern Luzon. The Shobu Group was primarily gathering its units in a desperate last-stand position along the rugged valley of the Asin River, an area known for its difficult terrain. Interestingly, General Krueger underestimated Yamashita's strategic intentions, still expecting him to make his final stand in the Cagayan Valley, located in the northern part of Luzon. With this assumption, Krueger believed that if General Beigthler’s 37th Division could maintain its rapid advance towards Aparri, situated at the northern tip of Luzon, they might be able to conclude the Luzon Campaign in a pivotal stroke.

However, intelligence indicated that units of the Shobu Group were retreating into the Cordillera Central mountain range, a formidable natural barrier, located between Routes 4 and 11. In response, Krueger ordered the 1st Corps to exert strong pressure on this mountainous region from the north, south, and west. To implement this strategy, General Swift directed the 6th, 25th, and 33rd Divisions to clear the supply route between Baguio and Aritao, ultimately sealing off Yamashita's last-stand position from the south. Meanwhile, Colonel Volckmann's guerrilla forces were instructed to advance east from Cervantes to capture the crucial junction of Routes 4 and 11 at Sabangan. Recognizing the importance of controlling key roadways, the 63rd Regiment was tasked with pushing up Route 4 to seize the strategic location of Kiangan. In the south, the 130th Regiment began probing southeast towards Pigkian, while the 20th Regiment continued to apply pressure on the remnants of the now-battered 2nd Tank Division. Ultimately, General Iwanaka’s weakened forces narrowly avoided entrapment along the Bambang-Pingkian road, retreating northward via treacherous mountain trails and river valleys. They reached the Tubliao area just as early July arrived, illustrating the persistent and relentless nature of this campaign.

Looking northward from Cervantes, Volckmann’s guerrilla fighters launched attacks toward both Mankayan and Sabangan. By the end of June, their efforts had pressured the beleaguered 19th Division to hastily withdraw from Bontoc, a significant town located in central Luzon, and Sabangan. However, General Ozaki’s forces maintained a formidable defensive position at the Lepanto Mine, an area known for its mineral wealth and strategic significance. On June 16, the 63rd Regiment began its advance up Route 4, which runs north through the central highlands toward Kiangan, a town that was crit
