Belligerents
Background
When Cao Cao moved to cross Guanzhong, nominally against Zhang Lu of Hanzhong, the Xiliang warlords read it as a blade aimed at themselves. A coalition recorded at a hundred thousand under Ma Chao and Han Sui massed at Tong Pass — Ma Chao rising even with his father Ma Teng held hostage at court.
Course
The Xiliang cavalry hit like a storm; crossing the Wei River, Cao Cao came within moments of death under Ma Chao’s sudden charge — Xu Chu holding up a saddle one-handed against the arrows as he rowed his lord across. Legend had Cao Cao cutting off his own beard and shedding his robe to escape. Judging a frontal decision impossible, he took Jia Xu’s wedge-driving plan: a warm, chatty reunion with the older Han Sui, then a letter to him with suspicious erasures. The moment mistrust split the coalition, Cao Cao attacked and scattered it.
Outcome & impact
Guanzhong was pacified and Cao Cao’s western flank secured; Ma Teng’s clan was executed the following year. The defeated Ma Chao, after further attempts, finally joined Liu Bei and became a Tiger General of Shu. Ma Chao’s force undone by Jia Xu’s guile — the textbook campaign of the discord stratagem.
History vs. the novelHistoryvsNovel
The novel’s shirtless duel between Xu Chu and Ma Chao is invention, but the beard-cutting tale, Xu Chu’s river stand and the discord scheme all have roots in the record. The novel also reverses the true order of Ma Chao’s rising and Ma Teng’s execution.
