The Yuan fleet crossed the sea and landed in Hakata Bay on 19 November, a short distance from Dazaifu, the ancient administrative capital of Kyūshū. The following day brought the Battle of Bun'ei (文永の役), also known as the "First Battle of Hakata Bay". The Japanese forces, being inexperienced with non-Japanese tactics, found the Mongol army perplexing. The Yuan forces disembarked and advanced in a dense body protected by a screen of shields. They wielded their polearms in a tightly packed fashion with no space between them. As they advanced they also threw paper and iron casing bombs on occasion, frightening the Japanese horses and making them uncontrollable in battle. When the grandson of a Japanese commander shot an arrow to announce the beginning of battle, the Mongols burst out laughing. The battle lasted for only a day and the fighting, though fierce, was uncoordinated and brief. By nightfall the Yuan invasion force had forced the Japanese off the beach with a third of the defending forces dead, driving them several kilometres inland, and burning Hakata. The Japanese were preparing to make a last stand at Mizuki (water castle), an earthwork moat fort dating back to 664. However the Yuan attack never came. One of the three commanding Yuan generals, Liu Fuxiang (Yu-Puk Hyong), was shot in the face by the retreating samurai, Shōni Kagesuke, and seriously injured. Liu convened with the other generals Holdon and Hong Dagu back on his ship.
