Yi Sun-sin
On April 13, 1592, the Imjin War broke out just as Yi had foreseen. Joseon was not prepared for war. Japan occupied nearly all of Korea. Yi had already prepared for war, so he led his navy to victory in every battle he fought during seven years of war with the Japanese. In the battle of Hansan, using crane wing formation he captured and sank fifty nine of the seventy-three Japanese ships. In the battle of Myeongnyang, he defeated 333 enemy ships with 13 ships his own. This victory has regarded as one of the miracle victories of the world.
