General MacArthur kept his promise to return to the Philippines on 20 October 1944. The landings on the island of Leyte were accompanied by a force of 700 vessels and 174,000 men. Through December 1944, the islands of Leyte and Mindoro were cleared of Japanese soldiers. During the campaign, the Imperial Japanese Army conducted a suicidal defense of the islands. Cities such as Manila were reduced to rubble. Around 500,000 Filipinos died during the Japanese Occupation Period.
