Zhu Ran
In 219, Pan Zhang participated in a campaign led by Sun Quan's general Lü Meng to seize control of Jing Province from Guan Yu, a general under Liu Bei. Pan Zhang and Zhu Ran blocked Guan Yu's retreat routes and stationed at Jiashi () when they reached Linju County (臨沮縣; present-day Yuan'an County, Hubei). Guan Yu, along with his son Guan Ping and subordinate Zhao Lei (), were captured alive in an ambush laid by Ma Zhong (), a Major () under Pan Zhang. In recognition of Pan Zhang's contributions, Sun Quan split Yidu and Zigui counties to form Guling Commandery () and appointed Pan as the Administrator () of the commandery, in addition to promoting him to General Who Inspires Might () and enfeoffing him as the Marquis of Liyang (). When Gan Ning died, Sun Quan placed Gan's subordinates under Pan Zhang's command.
