Sima Yong
In early 304, when the regent Sima Ai the Prince of Changsha (Emperor Hui's brother) was battling the forces of Sima Ying the Prince of Chengdu (also Emperor Hui's brother) and Sima Yong the Prince of Hejian (grandson of Emperor Hui's great-granduncle Sima Fu the Prince of Anping), even though Sima Ai was fighting off the overwhelming force that Sima Ying and Sima Yong had, Sima Yue became convinced that a victory was impossible, and he seized Sima Ai and delivered him to Sima Yong's general Zhang Fang (張方), who executed Sima Ai cruelly by burning him to death. Sima Ying controlled the government remotely, with Sima Yue being one of the generals who stayed in Luoyang to execute Sima Ying's orders.
