潘璋
In late October 222, Cao Pi ordered Cao Xiu, Zhang Liao and Zang Ba to attack Dongkou (洞口); Cao Ren to attack Ruxu (濡須); and Cao Zhen, Xiahou Shang, Zhang He and Xu Huang to besiege Nan Commandery (南郡). In response, Sun Quan put Lü Fan in command of five armies to resist Cao Xiu; Zhuge Jin, Pan Zhang and Yang Can (楊粲) were dispatched to relieve the siege on Nan Commandery which was being defended by Zhu Ran while Zhu Huan defended the fortress of Ruxu from Cao Ren.
