Deng Ai
Deng Ai reached the pinnacle of his career in 263, when he led Wei forces to conquer Shu. By leading a strike force through a shortcut across dangerous mountainous terrain, Deng Ai showed up in the vicinity of the Shu capital, Chengdu, and took the enemy by surprise. After a failed attempt by the Shu general Zhuge Zhan to stop Deng Ai at Mianzhu, the Shu emperor Liu Shan voluntarily surrendered to Deng Ai and brought an end to the Shu state. Following his success in the Shu campaign, Deng Ai became arrogant about his achievements and showed disregard for the Wei government's authority. The Wei general Zhong Hui exploited and manipulated Deng Ai's arrogance to great effect. In 264, Deng Ai was arrested by Wei Guan and Zhong Hui, who were acting under order by the Wei regent Sima Zhao. He was placed in a prison cart and escorted to the capital Luoyang, but was killed en route by soldiers sent by Wei Guan. His sons were executed as well. His surviving family members were exiled but allowed to return in 265 after the Jin dynasty was established.
