Cao Ren
The third invasion was not directed at the region of Nanjing or the Jing Province, but closer to the Wu king Sun Quan. The late Wu general Gan Ning helped take the Wei outpost in Yang Province at Ruxu, at the mouth of the Ruxu River into the Yangtze therefore Cao Ren attacked Ruxu. However, the assault also ended in retreat when Cao Ren learned that the other two armies attacking Dongkou and Jiangling had withdrawn from their positions.
