“Battle of Myeongnyang”

The Battle of Myeongnyang (鳴梁大捷) took place on September 16, 1597 (Lunar Calendar: September 13), when Admiral Yi Sun-sin led the Joseon navy against 133 Japanese warships with only 12 remaining ships at the Uldolmok Strait near Jindo, South Jeolla Province. This battle is considered one of the most dramatic naval battles in history and is recognized as a unique case in global naval warfare due to its extraordinary strategic execution.

In 1597, during the later stage of the Imjin War (1592–1598), Joseon was in dire straits. The Japanese launched the second invasion, known as the Jeongyu War, and sought to dominate the southern coast. The Joseon navy suffered a devastating defeat at the Battle of Chilcheonryang under the command of Won Gyun, leaving it nearly annihilated. Admiral Yi Sun-sin, who had been unjustly imprisoned, was reinstated as the naval commander but found himself left with only 12 warships. Meanwhile, the Japanese navy, with a fleet of 133 ships, aimed to secure complete dominance over Joseon’s waters. However, Admiral Yi did not give up; instead, he leveraged his strategic prowess and the treacherous tidal conditions of Uldolmok to secure a miraculous victory.


2. Chronological Progression of the Battle of Myeongnyang

1) The Eve of Battle – Japanese Advance and Yi Sun-sin’s Decision

In mid-September 1597, the Japanese navy advanced northward along the southern coast to invade Jeolla Province. Admiral Yi recognized that the Myeongnyang Strait (Uldolmok) had powerful currents and a narrow passage that could hinder large fleets. He decided to make his final stand there, rallying his 12 remaining ships and preparing his men for a desperate battle.

2) September 16 – The Battle Begins with Joseon’s Preemptive Strike

6:00 AM: The Japanese vanguard began entering the strait. Yi Sun-sin positioned his flagship at the front to lure the enemy while utilizing the strong currents to limit their maneuverability. Overconfident in their numerical superiority, the Japanese fleet advanced rapidly into the narrow waters.

8:00 AM: Yi Sun-sin’s flagship charged into the enemy lines and initiated an aggressive bombardment. The powerful cannons of the Joseon warships began sinking the Japanese vanguard. However, the Japanese navy sought to encircle the outnumbered Joseon fleet.

3) 10:00 AM – The Currents of Uldolmok Turn the Tide

10:00 AM: As the powerful tidal currents of Uldolmok began to surge, the Japanese fleet was thrown into chaos. The tightly packed enemy ships collided with each other, losing their ability to maneuver.

11:00 AM: The Japanese, attempting to maintain their formation, found themselves easy targets. Yi Sun-sin seized this moment and launched relentless cannon fire. Explosions engulfed enemy ships, and panicked Japanese soldiers leaped into the sea in a desperate attempt to escape.

4) Noon – The Tide Turns, Japanese Forces Retreat

12:00 PM: Yi Sun-sin continued to maneuver his ships strategically, further disorienting the enemy fleet. Despite their overwhelming numbers, the Japanese found themselves trapped in the chaotic waters of the strait, unable to counter the Joseon navy’s precise attacks.

1:00 PM: The Japanese command ordered a retreat. The surviving ships, battered and demoralized, tried to escape with the ebbing tide. The Joseon navy continued their pursuit, firing upon the fleeing enemy.

3:00 PM: Over 31 Japanese ships were destroyed, and the Joseon navy, with only 12 ships, emerged victorious. This triumph was a testament to Yi Sun-sin’s brilliance and the unwavering determination of his fleet.
