     On February 25, 1945, during the Battle of Manila, the capital of the Philippines, the Japanese Army charged in a "one man can defeat ten men" strategy with the Banzai attack. Nine Japanese soldiers were killed by American troops in the assault on General Luna Street inside Manila Castle. The bodies of the nine Japanese soldiers killed by the Americans in the Banzai assault lay scattered in the streets. The banzai assault referred to the Allied forces' suicidal man-wave attacks and swarms of Japanese infantry in the Pacific War. It originated from the Japanese soldiers' war cry, "Hail to the Emperor". It was shortened to banzai to refer to the tactics of the Imperial Japanese Army, especially during the Pacific War. As a means of thwarting the eventual Allied forces, the battle was a suicide attack that was foreseen as a defeat.

　By the morning of February 23, the Americans had isolated the last of the Japanese forces inside the government buildings within the walls of Manila. To retake the walled city of Manila, the Americans fired a massive 10,000 artillery and mortar rounds per hour. The Americans eliminated the last Japanese troops still holed up within the handful of government buildings surrounding the walled city of Manila. Survival was already no longer an option for the Japanese soldiers. Tens of thousands of Filipino men, women, and children were recklessly slaughtered in the most brutal manner and taken out of the way. The Japanese army summoned the last remaining troops and destroyed themselves in a banzai attack that crushed them to pieces. The U.S. forces destroyed the Legislative Yuan with artillery, sent in assault troops, and the building where the Japanese forces, resisting to the last, were holed up fell at noon on February 28.

      In the invasion of the Philippines by U.S. forces in the Pacific War, the Battle of Manila broke out between February 3 and March 3, 1945. American and Filipino forces clashed with Japanese forces in the Philippine capital, Manila, in a month-long battle that resulted in the deaths of more than 100,000 Manila residents and the complete devastation of the city. It was the worst urban battlefield fought by American forces in the Pacific War. Japanese forces committed mass murder against Filipino civilians during the fighting, and American firepower killed many Filipinos. Japanese resistance and American bombardment devastated and destroyed much of the architecture and cultural heritage of Manila since its founding. The Battle of Manila ended the nearly three-year Japanese occupation of the Philippines (1942-1945).

    Approximately 1,010 American soldiers were killed and 5,565 wounded in the Battle of Manila. At least about 100,000 Filipino civilians died as a result of the deliberate massacre of Manila by the Japanese and the bombardment and aerial bombardment by both Japanese and American forces. The death toll for the Japanese forces reached approximately 16,665 within the walled city alone. In the Battle of Manila, the Japanese forces erupted in the brutal Manila Massacre against Filipino civilians in the Philippine capital city of Manila. The total number of civilians killed by Japanese as well as American artillery and gunfire was estimated at at least 100,000.
