The Battle of Tong Gate (潼関の戦い, rōmaji: Dōkan no Tatakai) was a rebellion raised against Cao Cao after the Battle of Chibi. Historically, the battle occurred because Cao Cao ordered an expedition against Zhang Lu, but the warlords of Xiliang misinterpreted Cao's behavior, and mistakenly thought that Cao was trying to attack them instead.
