Yong-le: Year 11, Month 12, Day 7
29 Dec 1413
On this day, the Ying-guo Duke Zhang Fu and the Qian-guo Duke Mu Sheng, the regional commanders of Jiao-zhi who had joined forces to eliminate the bandits, reached Shun Subprefecture. The bandit leader Ruan Shuai and the others were encamped at Ai-zi River and had prepared an ambush. Fu and the others advanced in battle rank. The bandits had also occupied the pass at Mt. Kun-zhuan and had divided into three forces to do battle. Each force was led by elephants and they were followed by the bandit soldiers. Fu whipped his horse and led the troops first against the bandit's left flank and then rushed at the main force. The troops drew their bows and fired at the elephant drivers, toppling them from their elephants. They then fired at the elephants' trunks upon which the elephants turned and fled. They trampled the bandit ranks, giving rise to great disorder, upon which guard commander Yang Hong and others bravely rushed into the fray and fired their arrows with great force at the bandits. The bandits were greatly defeated. The Vice Commissioner-in-chief Zhu Guang was at that time locked in desperate battle with the right flank force and Fu ordered the Commander Xue Ju to go and aid him. The bandits were also defeated there. The false Junior Guardian Ruan Shan was beheaded while the false Generals Pan Jing, Ruan Xu, Ruan Yuan-xiong and Huang Yuan-ke, the false Commandant Ruan Du and others, a total of 56 persons, as well as 870 of the bandit soldiers, were captured alive. The others were pursued to the Ai-mu River, where was found the false "Concurrent Grand Mentor, Conferred with Inner Access and Grand Cavalry General of the Regions of Yi-an, Xin-ping and Shun-hua" seal, which had been left behind by Ruan Shuai. The remnant bandits scattered and were unable to regroup. The Xiang-ting Marquis Deng Tie, the younger brother of Deng Rong, as well as Pan Mu (Alt: Pan Lu), Pan Qin and other false generals of the Jin-wu Guard and other guards, and the false Subprefectural Magistrate Zhi Ju-che surrendered one after another, while the false Senior Generals He Su (Alt: He Li) and Pan Xi sent their sons to advise their return to allegiance.
