The Manila massacre (Pagpatay sa Maynila or Masaker sa Maynila), also called the Rape of Manila (Paggahasa ng Maynila), involved atrocities committed against Filipino civilians in the City of Manila, the capital of the Philippines, by Japanese troops during the Battle of Manila (3 February 1945 – 3 March 1945) which occurred during World War II. The total number of civilians who were killed by the Japanese as well as American artillery and firing is estimated to be at least 100,000. The Manila massacre was one of several major war crimes committed by the Imperial Japanese Army, as judged by the postwar military tribunal. The Japanese commanding general, Tomoyuki Yamashita, and his chief of staff Akira Mutō, were held responsible for the massacre and other war crimes in a trial which started in October 1945. Yamashita was executed on 23 February 1946 and Mutō on 23 December 1948. "The Americans who have penetrated into Manila have about 1000 troops, and there are several thousand Filipino soldiers under the Commonwealth Army and the organized guerrillas. Even women and children have become guerrillas. All people on the battlefield with the exception of Japanese military personnel, Japanese civilians, and special construction units will be put to death." Before the battle, deciding that he would be unable to defend Manila with the forces available to him, and to preserve as large a force as possible in the rural mountain Luzon region of the Philippines, General Tomoyuki Yamashita had insisted on a complete withdrawal of Japanese troops from Manila in January 1945. However, Yamashita's order was ignored by about 10,000 Japanese marines under Rear Admiral Sanji Iwabuchi who chose to remain in Manila. About 4,000 Japanese army personnel were unable to leave the city due to the advance of the American and Filipino forces. In the Battle of Manila from February to March 1945, the United States Army advanced into the city of Manila in order to drive the Japanese out.
