Sima Daozi
Later that year, angry that Sima Daozi had seized part of his domain and given it to his associate Wang Yu (王愉), Yu Kai (庾楷) the governor of Yu Province (豫州, then modern central Anhui) persuaded Wang Gong and Yin to start another rebellion aimed at the removals of Wang Yu and another associate of Sima Daozi's, Sima Shangzhi (司馬尚之) the Prince of Qiao. However, not being actually a military man himself, Yin gave the commands of the forward armies to Huan Xuan and Yang Quanqi (楊佺期). They quickly advanced toward the capital Jiankang, but Wang Gong's general Liu Laozhi (劉牢之) then turned against him, capturing and executing him. With Wang Gong dead, Sima Daozi next tried to destroy Yin's coalition by ordering him deposed and giving his post to Huan Xuan's cousin Huan Xiu (桓脩), while giving Jiang Province (江州, modern Jiangxi and Fujian) to Huan Xuan and Yong Province (雍州, then modern northern Hubei and southwestern Henan) to Yang. Huan and Yang hesitated—not willing to turn against Yin immediately but wanting to accept the powerful posts. This caused an immediate withdrawal of Yin's troops, as Yin wanted to resecure his Jing Province, and soon forced Sima Daozi to return the post to him, but the seeds of dissension between Huan, Yin, and Yang were sown. Yin, apprehensive of Huan, soon entered into an alliance with Yang. However, he was also apprehensive of Yang, and therefore repeatedly stopped Yang's plans to attack Huan together.
