In terms of the amount of men who died at Pearl Harbor on December 7, 1941, the Japanese Imperial Army won Pearl Harbor during their early morning attack. Overall 9 U.S. ships were sunk and 21 severely damaged. 2,350 people died and 1,178 injured. However, the Japanese just won the battle, not the war. The U.S. dropped two atomic bombs on the Japanese cities of Nagasaki and Hiroshima in August of 1945, essentially ending the Japanese resistance.
