Later that year, the Cao Wei general Zhuge Dan, believing that the regent Sima Zhao (Sima Shi's brother) was about to usurp the throne, declared a rebellion and requested Eastern Wu assistance. A small Eastern Wu detachment, led by Wen Qin, quickly arrived to assist him, but Sun Chen led the main forces and chose to camp a long distance away from Shouchun, where Zhuge Dan was besieged by Sima Zhao, and did nothing. When Sun Chen instead ordered the general Zhu Yi to try to relieve Shouchun with tired and unfed troops, Zhu Yi refused so Sun Chen executed him, bringing anger from the people, who had admired Zhu Yi's military skills and integrity. With Sun Chen unable to do anything, Zhuge Dan's rebellion failed in 258, and Wen Qin's troops became captives of Cao Wei.
