Over the course of his career, Admiral Yi fought in at least 23 recorded naval engagements, all against the Japanese. In most of these battles, he was outnumbered and lacked necessary supplies. His most famous victory occurred at the Battle of Myeongnyang, where despite being outnumbered 333 (133 warships, at least 200 logistical support ships) to 13, he managed to disable or destroy 31 Japanese warships without losing a single ship of his own. Yi died from a gunshot wound at the naval Battle of Noryang on December 16, 1598. His last words were: "The battle is at its height. Beat my war drums. Do not announce my death".
