The Japanese invaded and occupied the Philippines from 1942 to 1945. The invasion began on December 8, 1941, just hours after the attack on Pearl Harbor. Like at Pearl Harbor, American planes in the Philippines were destroyed on the ground. General Douglas MacArthur was forced to retreat his troops to Bataan and later escaped to Australia. The 76,000 American and Filipino troops on Bataan surrendered in April 1942 after months of fighting. A resistance movement opposed the Japanese occupation, which only had control over 12 of 48 provinces by the end of the war. MacArthur fulfilled his promise to return on October 1944, landing over 700 vessels and 174,000 men on Leyte.
