According to Wikipedia "Mongol invasion of Japan",
"First invasion (1274)[edit]
In 1274, the Yuan fleet set out with an estimated 15,000 Mongol and Chinese soldiers and 8000 Korean soldiers in 300 large vessels and 400-500 smaller craft, although figures vary considerably depending on the source. They landed on Komodahama beach on Tsushima Island on October 5, 1274. So Sukekuni, governor of Tsushima, led a cavalry unit of 80 to defend the island, but he and his outnumbered unit were killed in the engagement. The Mongols, Chinese and Koreans occupied the island and killed many civilians.[6]
The Mongols and Koreans subsequently invaded Iki. Tairano Takakage, the Governor of Iki, fought the invaders with about 100 of his cavalrymen, but he killed himself after his unit was defeated. The Mongols, Chinese and Koreans slaughtered many civilians in Iki.[6] "
