Yi Sun-sin — The Admiral Who Never Lost

Hi there, and welcome to 8 Minute Lives. In the autumn of 1597, a Korean admiral stood on the deck of a warship in a narrow strait, watching over a hundred Japanese vessels sail toward him. He had thirteen ships. Thirteen. Months earlier he had been dragged from command in chains, tortured, and demoted to a common soldier. Now his king had handed him back a fleet that barely existed and asked him to save the country with it. His name was Yi Sun-sin. And by the end of that day, he would win one of the most lopsided naval victories ever recorded. But let's start at the beginning. Yi Sun-sin was born in 1545 in Seoul, into a respectable family that had fallen on hard times. Korea at this point was ruled by the Joseon dynasty, a Confucian state where the surest path to status ran through civil service examinations — books, poetry, philosophy. Yi chose the military exam instead, a less prestigious route. And even that didn't go smoothly. During the test, at age twenty-eight, he fell from his horse and broke his leg. According to tradition, he splinted it with a willow branch and got back on. He still failed that attempt, and only passed four years later, at thirty-two. Old, by the standards of the time. What followed was an unglamorous career on the frontiers, fighting nomadic raiders in the north. Yi was honest to the point of stubbornness, and he refused to flatter superiors or bend rules for the well-connected. It cost him. He was demoted more than once for offenses that seem to have been largely political. By his mid-forties, he looked like a man whose career had stalled for good. Then, in 1591, everything changed. A perceptive official recommended him for command of a naval district on Korea's southern coast, a huge promotion. The timing was extraordinary, because across the sea, Japan was preparing for war. Japan had just been unified after a century of civil war by the warlord Toyotomi Hideyoshi, and Hideyoshi had a staggering ambition: he would conquer Ming China, and Korea was the road he planned to march through. In 1592 he launched an invasion with roughly 158,000 battle-hardened troops. Korea's land armies, unprepared after two centuries of peace, collapsed. Seoul fell within three weeks. The king fled north. It looked, briefly, like the end of the country. But Hideyoshi's plan had a weakness. His armies needed supplies, and those supplies came by sea, along the southern coast. And that coast belonged to Yi Sun-sin. Yi had spent his year in command preparing obsessively. He drilled his crews, stockpiled supplies, and oversaw the revival of a remarkable vessel called the turtle ship — a heavily armed warship with a covered deck studded with iron spikes, so that Japanese soldiers, who liked to win battles by boarding enemy ships and fighting hand to hand, simply couldn't get aboard. Korean ships also carried far more cannon. Yi's approach was to keep his distance, use the tides and narrow channels he knew intimately, and pound the enemy to pieces before they ever got close. It worked, again and again. Through 1592 Yi won a string of victories, culminating in the Battle of Hansan Island, where he lured the Japanese fleet into open water and enveloped it in a formation shaped like a crane's wing. Dozens of enemy ships were destroyed. The supply line to the Japanese armies in the north was effectively cut, and the entire invasion began to starve and stall. Ming China sent troops, the war ground into stalemate, and negotiations dragged on for years. Then came the fall. When fighting resumed in 1597, the Japanese fed false intelligence to the Korean court, luring Yi toward a trap. Yi judged the reported movement to be a deception and refused to sail. At court, where he had jealous rivals and a suspicious king, this looked like disobedience. He was arrested, hauled to Seoul, and tortured. Some officials wanted him executed. In the end he was spared, stripped of rank, and sent to serve as an ordinary foot soldier. During this period his mother died. His diary, which survives, records his grief in raw, broken entries. Command of the navy passed to a rival, Won Gyun, who promptly led the fleet into exactly the kind of trap Yi had avoided. At the Battle of Chilcheollyang, the Korean navy was annihilated. Of well over a hundred ships, only about a dozen escaped. Won Gyun was killed. In desperation, the court reinstated Yi. He took stock: thirteen ships. The court suggested he abandon the sea entirely and fight on land. Yi wrote back a letter that Koreans still quote today. It said, in essence: I still have twelve ships, and as long as I live, the enemy will never be safe on this sea. In October 1597 he made his stand at Myeongnyang, a narrow strait with ferocious tidal currents. The Japanese came with a fleet of over three hundred vessels, of which some 133 were warships. In the tight channel, their numbers counted for little. For a time Yi's own flagship fought almost alone, his other captains hanging back in terror, until his example — and his signals, which carried an unmistakable edge of threat — drew them into the fight. Then the tide turned, literally, driving the Japanese ships into one another. By day's end, around thirty Japanese warships had been destroyed. Yi had lost none. The invasion's western advance by sea was finished. A year later, Hideyoshi died, and the Japanese armies began withdrawing. Yi, now fighting alongside a Ming Chinese fleet, was determined they would pay a price on the way out. At the Battle of Noryang, in December 1598, the allied fleet intercepted a large Japanese force and shattered it. Near the height of the fighting, Yi was struck by a stray bullet. By most accounts, his dying order was to keep his death hidden until the battle was won. It was. In twenty-three engagements across seven years, he had never lost one. What makes Yi Sun-sin remarkable is the arc of it all. A man his own government imprisoned and tortured went straight back to sea and saved that government anyway. He fought with almost nothing, against absurd odds, out of a sense of duty that his superiors rarely deserved. In Korea today he stands in bronze in the center of Seoul, sword in hand, facing the direction the invaders once came from. Even Japanese admirals, centuries later, studied him with open admiration. Few commanders in history have won so completely. Fewer still were treated so badly by the country they were winning for.
