Cheng Han
The state of Cheng Han's affairs brought the attention of Jin's ambitious general Huan Wen. In winter 346, Huan submitted a report requesting to attack Cheng Han—and then, without approval from the imperial government, immediately departed. In spring 347, Huan slipped past Cheng Han forces sent to intercept him, commanded by Li Fu (李福), Li Quan (李權), and Zan Jian (昝堅), advancing directly on Chengdu. Cheng Han forces, in fear, largely collapsed. However, Li Shi gathered the remaining troops and mounted a counterattack that was initially successful. Huan, in fear, ordered retreat—but his signal officer, in panic, beat his drums (signifying attack) rather than his gong (signifying retreat). The Jin forces attacked harder and defeated Cheng Han forces, allowing Huan to march upon Chengdu's gates. Li Shi fled, but soon had a messenger submit a humble surrender petition to Huan. He then surrendered in person after binding himself and bringing a coffin—signifying readiness to be executed. Huan released him and escorted him to the Jin capital Jiankang, where Emperor Mu of Jin pardoned him and created him the Marquess of Guiyi. He died in 361.
