Okpo Battle The Okpo Battle was the first Battle of Admiral Yi Sun-sin. The Admiral sent the scouting ship first around the Busanpo area to monitor. Yi Sun-sin did not engage in battle until he learned of the size of the Japanese fleet and its battle method. On May 7, he started with the fleet of Won Gyun toward Okpo. The Japanese fleet was off from the vessels and looted the nearby villages in the Okpo area. As soon as the Japanese discovered the Joseon Fleet, they hurried to get back on their vessels. The Admiral waited until all Japanese forces get on the ships and began to fire the canon once they all got on board. The fleet of the Admiral took the straight line formation, lining up the ships in one line. The Admiral did not use the strategy to get onto the enemy ship that had frequently used at the time. He ordered to shoot guns on the Japanese forces and destroyed most of the Japanese fleet then. The victory of the Okpo Battle was the first triumph for Joseon since the beginning of the Imjin War.
