Still later, in the closing years of the Ashikaga shōgunate, outlaws from Kiushū entered China and Korea in constantly increasing numbers for purposes of plunder, the provinces on the Chinese littoral sustaining great injury at the hands of these marauders. On the flags of the Japanese piratical ships were inscribed the ideograms _Hachiman-gu_ (Hachiman, the God of War). The Chinese consequently termed these vessels _Papan-sen_, "Papan" being the Chinese pronunciation of "Hachiman," and regarded them with the greatest apprehension. With them, too, Chinese pirates were associated, and the people of China suffered so much from their raids that the emperor deputed two of his principal generals to attack and destroy the raiders, but the task could not be successfully accomplished. From Korea, too, came a request to the Sō family that they would restrain the Japanese from further incursions into the peninsula, but the head of the family paid no heed, and the result was that the Koreans treated with great cruelty a number of the inhabitants of Tsushima who happened to be sojourning in the peninsula. This procedure so enraged the people of Tsushima that, in 1510, they attacked Fusan in force, and having destroyed its fortifications, returned unmolested to Tsushima. After this, the pillage of the Korean coast towns by Japanese pirates continued without intermission. It will be seen in the next chapter that this long history of piracy in Korea culminated in an organized invasion into the peninsula of large Japanese forces under the leadership of their best generals.
