Jiangling County
The first objective of the Wei forces was to attack and capture Nan Commandery, which would open up the opportunity to capture Jiangling. The forces of Wei were dispatched from possibly Xiangyang and Fancheng. Cao Zhen, Xiahou Shang and Zhang He attacked Jiangling County, as Cao Pi moved a supporting force from the Wei capital Luoyang to Wancheng in case of any required backup. At this time, it was very critical and uneasy for the Wu forces, since the commander, Zhu Ran was in control of a very low number of troops. Quickly, the Wei forces overran the Wu forces at Nan Commandery, after Zhang He defeated Sun Sheng (孫盛). The Wei forces then made way to assist the main army's siege of Jiangling County.
