Battle of Dongkou 洞口之戰

In the 9th month of autumn of the 3rd year of Huangchu (222), Wei sent Cao Xiu, Zhang Liao and Zang Ba out to Dongkou. Cao Xiu, as Grand General Who Conquers the East and granted the yellow battle-axe, commanded Zhang Liao and others and more than twenty armies of the various provinces and commanderies, and Zhang Liao, though ill, also went by boat with Cao Xiu to Hailing and faced the Yangtze. Sun Quan had Lü Fan lead Xu Sheng, Quan Cong, Sun Shao (孫韶) and others to hold Dongkou with a fleet, and the camps of the two armies faced each other.

Cao Xiu, having reached Dongpukou, submitted a memorial saying he would sweep south of the river with his elite troops, and Cao Pi, fearing that he would cross the river at once, sent an edict by post-horse to stop him. Dong Zhao, who was at the emperor's side, said that since Zang Ba and the others already enjoyed wealth and rank and would not risk danger, Cao Xiu could not cross on his own. Records, Wei 14 §70–72

In the 11th month a great wind blew, and the boats of Lü Fan and the others broke their cables and drifted away or capsized; several thousand drowned, and the boats that reached the shore were captured by the Wei army. The Biography of Dong Zhao records that the fierce wind drove all the enemy's boats to below the camps of Cao Xiu and the others, who beheaded and captured them so that the enemy scattered and fled, but that despite an edict urging them to cross the river quickly the army did not advance in time, and the enemy's rescue boats arrived. Wu Can, while the other boats were pushing people in the water away with spears, pulled them aboard and saved more than a hundred.

He Qi, having come late because of the long road, did not cross the river but stayed at Xinshi, so his army alone remained intact, and the generals relied on it to recover their momentum. Xu Sheng gathered the remaining soldiers and faced Cao Xiu across the river, and when Cao Xiu attacked with boats, he held them off with few troops. Cao Xiu had Zang Ba raid Xuling with 500 light boats and 10,000 men ready to die, burning the siege carts and killing or capturing several thousand people, and Quan Cong and Xu Sheng pursued them and beheaded the Wei general Yin Lu.
