Angolpo (also sometimes called the Battle of the Yellow Sea). At Angolpo, the Korean fleet of fifty-seven vessels under Admiral Yi Sun-sin faced off against a numerically superior Japanese fleet of one hundred fifty-five ships under Admirals Wakisaka Yasuharu, Kuki Yoshitaka, and Kato Yoshiaki. Admiral Yasuharu's fleet of sixty-three ships was lured into the Hansan Bay by the outnumbered Korean fleet of warships and Turtle Ships, where it was caught and enveloped in Yi Sun-sin's famous crane formation. The trapped Japanese fleet was eviscerated by the Turtle Ship's weaponry, and found themselves unable to effectively counterattack due to the Turtle Ship's unprecedented nimbleness and maneuverability on the sea. Admiral Yi's fleet then attacked the ships of Yoshitaka and Yoshiaki, during which, victory was cemented for the Joseon. Turtle Ships greatly contributed to the total Japanese fleet loss of fifty-nine ships in the Battle of Angolpo. Today A turtle ship has been reconstructed by Geobukseon Research Center (거북선연구원), a private commercial company. They have done extensive research on the original design of the turtle ship, and made several real-size reconstructions of them for commercial use. These were deployed in a Korean drama, The Immortal Admiral Yi Sun-sin (불멸의 이순신). Several museums host turtle ships on display, and people can visit and go inside a 1:1 scale turtle ship that is anchored at Yeosu. North Korean delegations to the south seem to be more reserved about the significance of its historical role.
