Thirteen ships after the torture chamber
In 1597 Yi Sun-sin was arrested, tortured, and demoted to common soldier for refusing a royal order to attack on intelligence he suspected was a Japanese trap. His replacement, Won Gyun, then lost almost the entire Korean fleet at Chilcheollyang. Reinstated with about thirteen surviving ships, Yi used the narrow, fast tidal channel at Myeongnyang to defeat a Japanese force of more than a hundred ships, and he died a year later at Noryang ordering that his death be concealed until the battle was won.
