Zhuge Ke
Sima Shi was a capable politician and administrator, but he also quickly wanted to prove his military reputation. Towards the end of 252, he launched a major attack against Eastern Wu, whose founding emperor, Sun Quan, had recently died and whose current emperor, Sun Liang, was under the regency of Zhuge Ke. Zhuge Ke was able to deal Sima Shi's forces, headed by Sima Zhao, a major blow at the Battle of Dongxing, but Sima Shi maintained himself well by making humble admissions of faults to the public and promoting the generals who tried to stop his campaign. In 253, after Sima Shi defeated Zhuge Ke in a major battle, his reputation was established, while Zhuge Ke's own was undermined (due to Zhuge Ke's failure to admit fault), and Zhuge Ke soon fell while Sima Shi's power was affirmed.
