江陵県
In the winter of 208–209, Cao Cao was defeated by Sun Quan and Liu Bei at the Battle of Red Cliffs, but he still had a large army garrisoned at the northern part of Jing Province (covering present-day Hubei and Hunan). The following month, Sun Quan's general Zhou Yu led an attack on Jiangling (江陵; located in present-day Jingjiang 荆江, not to be confused with Jiangling County, Hubei), which was defended by Cao Cao's cousin Cao Ren.
