Xuan-de: Year 1, Month 11, Day 6
4 Dec 1426
On this day, the Cheng-shan Marquis Wang Tong, regional commander of Jiao-zhi, advanced the troops to attack the bandits, but was greatly defeated. The bandits subsequently surrounded Dong-guan. Previously, the bandit Li Shan had led his soldiers in attacking Jiao-zhi City and divided them into three forces. One approached from the West Gate and attacked the earth wall at Qing-wei. One came through the training ground and attacked Xia-guan. The Commissioner-in-chief Chen Jun let loose with firearms (火銃) and fire arrows (火箭) and drove them off. The other force attacked the small gate on the Bian River. The official Li An, who was serving in order to realize achievements, led crack troops to do battle with them. Large numbers of the bandits were killed or injured and, in the middle of the night, they fled. At this time, Tong and the others led troops out in separate forces. When the Assistant Regional Commander and Commissioner-in-chief Ma Ying reached Qing-wei, he came upon the bandits and did battle, greatly defeating them. They then went to Shi-shi County and joined with Tong's troops. Together, they proceeded to Ying-ping County and then encamped the army at Ning Bridge. The various generals all said that this place was dangerous, that it would be best to remain encamped and observe the bandit's strength and that an advance should not be considered lightly. Tong did not listen and he led the forces across the bridge. The road was all mud and slush and the men had to crawl along it with their horses. The bandits then launched their ambush and the Imperial army was defeated. The Minister Chen Qia was killed, while the Commander Li Teng and others fell into the bandits' hands. Tong was wounded and withdrew. When Li Li heard of this in Yi-an, he personally led his forces to Qing-tan to attack Bei River and other areas. Subsequently, he surrounded Dong-guan.
