Yong-le: Year 5, Month 6, Day 16
20 Jul 1407
Imperial orders were sent to Cheng Da, commander of the Embroidered-Uniform Guard, saying: "The man bandits in Liu-xun and other areas of Guang-xi have not yet been pacified. I have sent orders to the Xin-cheng Marquis Zhang Fu, regional commander of Jiao-zhi, and others, requiring that when they are withdrawing the troops, they join with the Commissioner-in-chief Han Guan in a combined punitive expedition. I have also ordered the three military commissions of Guang-dong, Hu-guang and Gui-zhou to deploy 20,000 troops. It is planned that they will arrive in Guang-xi on the first day of the 10th month (31 Oct 1407). They will then be placed under your command and are to be advanced along separate routes. This is an advance notice for you."
