Yong-le: Year 4, Month 12, Day 6
14 Jan 1407
On this day, the Xi-ping Marquis Mu Sheng, deputy general of the left of the force being sent on expedition to punish Annam, took control of the Xuan River. The army then established a camp on the Northern bank of the Tao River and forces were gathered facing Duo-bang City. The Xin-cheng Marquis Zhang Fu, "General for Subduing the Yi" sent the Yun-yang Earl Chen Xu, assistant commander of the left, at the head of a force to attack the forces on the Tao River and to manufacture pontoon bridges to allow troop reinforcements to cross. The Assistant Commissioner-in-chief and Cavalry Commander Zhu Rong and others defeated the bandit troops to the North of the Jia-lin River. Previously, the regional commander had proposed deploying reinforcements across the upper reaches of the river and thus he sent Rong and others with both cavalry and infantry 18 li down-river to there confront the bandits. Day by day the number of troops was increased, in order to deceive the bandits. The troops also built boats and rafts and made it appear that they were going to be reinforced, thereby beguiling the bandits. At this time the bandits sent soldiers across the river to steal the boats and rafts. Rong and the others then attacked them and utterly routed them.
