Yang Zhao
Xu Yin (), the commander of the Jin garrison at Badong Commandery (巴東郡; around present-day Fengjie County, Chongqing), led marine forces towards Jianping (建平; around present-day Zigui County, Hubei), while Yang Zhao (), the Inspector of Jing Province (also under Jin control), led troops towards Xiling. Lu Kang gave orders as such: Zhang Xian to reinforce Jiangling's defences; Sun Zun (), the Commandant of Gong'an County, to patrol the south river bank and resist Yang Hu; Liu Lü () and Zhu Wan () to guard against Xu Yin's attacks. He personally led three armies to hold off Yang Zhao with the aid of the defensive structures they constructed earlier. However, Lu Kang's subordinates Zhu Qiao () and Yu Zan () defected to Yang Zhao's side. Lu Kang said: "Yu Zan has been serving under me for a long time and he is very aware of my situation. He knows that the tribal soldiers in my army may be unwilling to follow my orders, so he will definitely suggest to the enemy to take advantage of this weakness." Hence, that night, Lu Kang immediately replaced the tribal soldiers in his army with other veteran soldiers whom he trusted more. The following day, as Lu Kang expected, Yang Zhao concentrated his attacks on the unit in Lu Kang's army which used to be made up of tribal soldiers, without knowing that they had been replaced. Lu Kang ordered his archers to retaliate, raining arrows on the enemy and inflicting heavy casualties.
