Kublai's Lost Fleet

In 1274 then 1281, Kublai Khan sent two massive fleets from China to conquer Japan. Both expeditions failed—repelled by Japanese defenders and, especially in 1281, destroyed by a typhoon that chronicles would call kamikaze, "divine wind."

Kublai Khan, Mongol emperor of the Yuan, already controlled China and Korea. Japan refused to submit; Kublai demanded tribute, the Kamakura bakufu shogunate refused. In 1274, a first fleet of some nine hundred ships transported tens of thousands of Mongol, Korean, and Chinese soldiers toward Kyushu. The Japanese resisted better than expected; at night, a storm dispersed the fleet and forced retreat. Kublai prepared a second, much more massive expedition.

In 1281, two fleets—east and south—converged toward Kyushu with perhaps one hundred forty thousand men. Samurai, entrenched behind stone walls built specifically, repelled assaults for weeks. Then, in late August, a devastating typhoon—the kamikaze of chronicles—destroyed most of the anchored ships. Thousands of soldiers drowned; surviving captives were executed or forcibly assimilated. Japan was never invaded.

The episode founded a national narrative: islands protected by the gods, invincible against continentals. The term kamikaze would be reused in the 20th century with a very different connotation. For historians, the failure shows the logistical limits of Mongol conquests beyond the steppes—sea, climate, distance ultimately stopped the era's largest empire.
