The Battle of Bun'ei also known as the First Battle of Hakata Bay was the first major attempt by the Mongol Empire to invade Japan. The Mongol-led force, including Mongols, Koreans, Chinese, and Jurchens, landed at Hakata Bay after raiding the nearby islands of Tsushima and Iki. Although the Mongols established positions on islands within the bay and launched attacks on the mainland, they were ultimately unable to secure a foothold and withdrew after several days. The battle demonstrated both the reach of the Mongol military and the difficulties of overseas operations in unfamiliar territory.
