Zhuge Ke
In 253, Zhuge Ke prepared for another invasion of Wei and said that he wanted to take advantage of Sima Shi's "youth and inexperience" (even though Sima Shi was 45 years old then). Despite strong opposition from some Wu officials, Zhuge Ke rallied an army from among all able-bodied men in Wu for the invasion. He also coordinated the invasion with Jiang Wei, a general from Wu's ally state Shu Han. (At the time, Jiang Wei was also actively launching a series of campaigns against Wei at Wei's western border.)
