Huan Wen vs Jiang Wei

Huan Wen led a campaign to conquer the Cheng Han state in Sichuan. He defeated the Cheng Han army and captured its capital Chengdu, annexing the region into the Jin Dynasty and expanding Jin territory.

Huan Wen launched a series of northern expeditions against the Former Qin and other states. He achieved initial victories but failed to hold territory, ultimately retreating due to lack of supplies and political opposition at court.

Huan Wen deposed Emperor Fei of Jin and installed Emperor Jianwen, a puppet ruler. He sought to usurp the throne but died in 373 before completing his plans, leaving his son Huan Xuan to later attempt the same.

After Zhuge Liang's death, Jiang Wei was appointed as the commander of Shu Han's military forces, tasked with continuing the Northern Expeditions against Wei. He was given command of the remaining troops.

Jiang Wei launched his first major campaign against Wei, attacking the Wei-held territories of Longxi and Nan'an. The campaign achieved limited gains but failed to capture key cities.

Over the course of his career, Jiang Wei launched eleven separate campaigns against Wei, each with varying degrees of success. These campaigns drained Shu Han's resources and manpower without achieving a decisive breakthrough.

Jiang Wei's forces were decisively defeated by Deng Ai at Taoxi. The defeat forced Jiang Wei to retreat and weakened Shu Han's military position.

After Deng Ai's surprise attack on Chengdu, Jiang Wei surrendered to the Wei general. He later attempted to restore Shu by conspiring with Zhong Hui, but the plot failed and he was killed.
