The Japanese Invasion & Conquest of the Philippines
Japanese naval and air forces began to simultaneously launch surprise strikes across the Southeast Asian countries including the Philippines hours after the attack on Pearl Harbor.
On December 8th, 1941, approximately 17 hours after Pearl Harbor, led by Japanese Lt. General Masaharu Homma, Japanese air forces began bombing Clark Field, a major American air base on the island of Luzon. Hangars, barracks, and warehouses were completely ruined as casualties increased. The American forces present were helpless in defense of the air base because most of the B-17 bombers and P-40 fighters were parked to refuel and therefore vulnerable to attack. As Japanese bombs rained on Clark Field, Japanese planes simultaneously attacked the base at Iba, also located on the island of Luzon. The initial Japanese aerial attacks resembled Pearl Harbor, as the Japanese successfully caught American forces by surprise, establishing Japanese air superiority.
