Jia Chong
In 260, the Wei emperor Cao Mao attempted to seize back power from the Sima family by staging a "coup d'état" against the regent Sima Zhao (Sima Zhou's half-brother). Sima Zhou, then holding the position of a Colonel of the Garrison Cavalry (屯騎校尉), led his troops to stop Cao Mao. However, his men dispersed in fear when Cao Mao shouted at them. Cao Mao eventually met his end at the hands of Cheng Ji (成濟), a subordinate of Sima Zhao's adviser Jia Chong.
