The Battle of Chibi (赤壁の戦い, rōmaji: Sekiheki no Tatakai) is a defining battle near the end of the Han Dynasty. On royal orders, Cao Cao led an expedition to the south and conquered a majority of Jing Province. He had Liu Bei on the run at Changban, yet Liu Bei escaped from his foe to the east and arranged a formal alliance with Sun Quan. After some debate, Sun Quan accepted the decision to fight back with Liu Bei. Led by the talented strategist, Zhou Yu, the combined navies clashed with Cao Cao's imposing fleet.
Two famous events for the battle include Huang Gai's ruse to Cao Cao and the damaging fire attack on the invading fleet. Romance of the Three Kingdoms particularly adds it own drama for the conflict, including an one-sided rivalry between Zhou Yu and Zhuge Liang, Cao Cao vying for the Two Qiaos, and the act of calling forth the southeastern winds for the fire attack's success.
The allied army scored victory against Cao Cao, who retreated back north with his forces. Again, Romance of the Three Kingdomsimparts a fictional chase for his head as he escaped from Chibi. His weakened grasp on Jing Province sparked Sun Quan's plans for expanding north at Nanjun. When his forces were repulsed by Cao Ren and other capable officers under Cao Cao, Liu Bei took this chance to claim four sections of Jing Province for himself. With each of the three powers continuing to build their forces, the foundations for the Three Kingdoms period began to take shape.
