[edit] Operational history
[edit] The Philippines
Plans for an invasion of the Philippines were finalized on November 13-15, by Lt General Masaharu Homma, Lt General Hideyoshi Obata, Vice Admiral Ibo Takahashi and Vice Admiral Nishizo Tsukahara.
These plans called for air attacks against the Philippines, beginning on X-Day, by the 5th Army Air Force Division and the 11th Naval Air Fleet. At this time, Imperial Japanese Army and Imperial Japanese Navy units were to land on Batan Island, Luzon (at: Aparri, Cagayan, Vigan, and Legazpi City), and at Davao, Mindanao, and to seize airfields. Following the elimination of American air support, the main body of the IJA14th Army was to land at Lingayen Gulf, while another force landed at Lamon Bay. These forces were then to attack Manila in a pincer attack. After this, the islands of Manila Bay were to be taken. In the resulting Battle of the Philippines (1942), Japanese forces accomplished their primary objectives.
