The Battle off Samar (Filipino: Labanan sa may Samar) was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. It was the only major action in the larger battle in which the Americans were largely unprepared. The Battle off Samar has been cited by historians as one of the greatest last stands in naval history; ultimately the Americans prevailed over a massive armada—the Japanese Imperial Navy's Center Force under command of Vice Admiral Takeo Kurita—despite their very heavy casualties and overwhelming odds.
