After the attack on Pearl Harbor, the Japanese swept across the Pacific, attacking Guam, Wake, Midway, and other important American bases in the Pacific. After capturing Guam and Wake, the Japanese made an all-out assault on the Philippines. The fighting at Bataan (a Phillippines Peninsula) and Corregidor (a small Philippines island) was especially tragic. President Roosevelt ordered General Douglas MacArthur to leave the Philippines so that he would not be captured. When Bataan and Corregidor surredered, over 60,000 Americans became prisoners to Japan. More than 10,000 American soldiers died in the Bataan Death March. General MacArthur said “I shall return” as a promise to the Filipinos.
