Xuan-de: Year 1, Month 10, Day 13
12 Nov 1426
The Cheng-shan Marquis Wang Tong, regional commander of Jiao-zhi, memorialized that the Commissioner Yuan Liang who accompanied the expedition to Jiao-zhi, had been defeated. At the time, Li Shan, one of Li Li's gang leaders, had occupied Guang-wei Subprefecture. Chen Zhi, an official serving in order to realize achievements, sent Liang and the Commanders Wang Mian and Si Guang to resist him. When the troops reached the place, Liang wanted to cross the river. However, the native-official regimental commander (營土官指揮) He Jia-kang said: "There will surely be an ambush there. We must be very careful and not proceed lightly." Liang did not listen and sent his commanders Tao Sen, Qian Fu and so on across the river to attack the bandits. The bandits ambushed the troops by coming from behind and killed Sen, Fu and the Battalion Commander Zhao Zhen. Over 500 native soldiers were lost. Liang was also taken. Both Tong and the regional inspecting censor advised of the events. As Wang Mian and Si Guang did not go to their assistance, the Emperor ordered Tong to demote them to soldiers so that they could realize achievements to atone for their offences. He also ordered Tong and the others to advance their troops to pacify the bandits.
