In 222, Jiang Ji accompanied the Wei general Cao Ren on a campaign against Wei's rival state, Eastern Wu, and led a detachment of troops to attack Xianxi (羨溪; northeast of present-day Wuwei County, Anhui). When Cao Ren wanted to attack the Wu-controlled dock at Ruxu (濡須; north of present-day Wuwei County, Anhui), Jiang Ji warned him: "The enemy has occupied the west riverbank and lined up their ships on the upper stream. By leading your troops to attack the island, you are heading straight into hell. This is a path to defeat and destruction." When Cao Ren ignored Jiang Ji's advice and led his troops to attack Ruxu, he ended up being defeated by the Wu defenders.
