大陸打通作戦
In early 1944, the Japanese Prime Minister General Hideki Tojo approved of plans for victory in Asia, calling for two operations, Operation U-Go as the invasion of India was code-named and Operation Ichi-Go which was intended to defeat China once and for all. The two operations in India and China were closely linked given that American supplies for China were flown over "the Hump" of the Himalayas and the Japanese wanted to take the Indian province of Assam in part to close the American air bases in India that sustained China at the same time that they were launching Operation Ichi-Go, the biggest Japanese offensive of all time, involving 2 million men. The Japanese knew that they lacked the logistics to invade India, and the plans for U-Go were based on the assumption that the British 14th Army would just collapse, allowing the Japanese 15th Army to capture enough food to prevent its men from starving to death. Following the Japanese 15th Army into India was the Indian National Army commanded by Subhas Chandra Bose, an ardent nationalist. The Japanese believed that the mere presence of Bose in India would inspire the men of the Indian Army to mutiny and murder their British officers, and set off an anti-British revolution that would allow the Japanese 15th Army to take all of India.
