Ironclad naval vessels were first used during the invasion of Korea by the Japanese warlord Toyotomi Hideyoshi in 1592. The Japanese arrived with 300,000 troops with a fleet of 200 ships under Ukida Hideiye who was met by Korean admiral Yi Sun-Shin with the Illsmall fleet of ironclad warships, called kobukson, or Turtle boats. There were several encounters between May to October where the Turtle boats destroyed the Japanese fleet without losing any of their own. In 1597, a second Japanese invasion fleet was decimated by Turtle boats, with the loss of some 300 Japanese ships and 50,000 soldiers. It was the largest naval engagement until the 20th century.
