About three weeks after the Battle of Okpo, Admirals Yi and Won sailed with a total of 26 ships (23 under Admiral Yi) toward the Bay of Sacheon upon receiving an intelligence report of a Japanese presence. Admiral Yi had left behind his fishing vessels that used to make up most of his fleet in favor of his newly completed Turtle ship. Admiral Yi ordered the fleet to feign withdrawal, which caused the Japanese to eagerly pursue the Korean fleet with their 12 vessels. With the Japanese ships drawn out of the safety of the harbor, the Korean navy countered, and with the Turtle Ship leading the charge, they successfully destroyed all 12 ships. Admiral Yi was shot by a bullet in his left shoulder, but survived.
