The Battle of Hansan Island (Korean: 한산도대첩) and the following engagement at Angolpo took place on 15 August 1592.

On 12 August, 1592 [Gregorian Calendar] they rendezvoused with Won Gyun at Noryang, bringing their total fleet strength to 56 warships.

Yi Sun-sin sent a small detachment forward to lure the Japanese fleet, and they took the bait, following them into open waters off Hansan Island.

The Korean fleet assumed a U-shaped crane formation with large warships in the center and lighter ships on its wings.

[citation needed] The Battle of Hansando is also portrayed in episode 74 of the TV drama series Immortal Admiral Yi Sun-sin.
