The Japanese fleet of approximately 333 ships (133 warships, at least 200 logistical support ships) entered Myeongnyang Strait in groups. The Japanese ships that made it through were met by 13 Joseon warships obscured by the shadows of the surrounding hills, ready with archers and cannons, and the melee-based Japanese found themselves unable to fight effectively and break through the superior Joseon ranged fire. The unpredictable current eventually wreaked havoc on the Japanese; their ships found themselves unable to maneuver and collided with each other when the tide reversed, while also presenting a perfect target for the Joseon naval artillery. Admiral Yi was astonishingly able to rout a force that outnumbered him more than 25 to 1 in ships alone. About 31 of the 333 Japanese ships that entered the Myeongnyang Strait were destroyed or damaged. Joseon losses on the other hand were around ten casualties and no ships lost. Kurushima Michifusa was killed on his flagship by Joseon archers; his body in its ornate armor was fished out of the water, his severed head was put on display to further demoralize the Japanese fleet.
