Zheng-tong: Year 8, Month 4, Day 4
3 May 1443
Imperial orders were sent to the Jing-yuan Earl Wang Ji, Minister of War and supreme commander of Yun-nan military affairs, and to the Regional Commander and Commissioner-in-chief of the Right Mu Ang. The orders read: "You memorial has been received, noting that Ava-Burma had previously stated that it wished to send the bandit leader Si Ren-fa, whom they had captured and imprisoned in the city of Ava, to the capital in fetters along with tribute, but that it now says that it will join with the government troops in eliminating Si Ji-fa and that when Meng-yang is taken and given to them, they will send Si Ren-fa to the capital. Their sentiments are obvious. When these orders arrive, you are to conduct a secret investigation. If Si Ren-fa truly has been captured by Ava-Burma and they obstinately refuse to send him to the capital, send persons to instruct Mu-bang and the native officials and chieftains in nearby areas to gather together men and horses. Then, when Autumn arrives, you will advance the troops. This bandit must be eliminated. Using yi to attack yi was a good tactic used by the ancients. Moreover, Ava-Burma is far in the distance. The Imperial army cannot penetrate deeply and an attack would be impossible without native troops. You should select and deploy 10,000 men to follow the force forward and add to its military power and display. You must put all your efforts into planning and ensure security. You are to memorialize on proposed arrangements."
