Jiang Wei’s night battle at Qishan and the withdrawal prompted by Huang Hao

Jiang Wei’s night battle at Qishan and the withdrawal prompted by Huang Hao is a reversal in which military victory fails to secure strategic freedom. Jiang Wei defeats Deng Ai and Sima Wang in successive engagements, but Wei’s commanders exploit court intrigue to have him recalled; his disciplined retreat saves the Shu army even as the recall interrupts his campaign. The episode sets battlefield competence against political vulnerability and ends with Jiang Wei back in Shu, still prepared to attack Wei again.

Political setting and the campaign

After Sun Xiu’s envoy reports that Shu is weakened by corrupt eunuchs, dishonest officials, and the poverty of its people, Wu warns that Sima Zhao may seize imperial power in Wei. Jiang Wei hears the report and immediately proposes an invasion of Wei. He advances through the Qishan hills and establishes a camp on the plains, carrying the campaign into territory Deng Ai has deliberately prepared as a trap.

Deng Ai has left the plains open to Jiang Wei while digging a long tunnel beneath the ground where the Shu camp is to stand. His design allows Wei forces to strike both from above and below. The plan makes the apparent ease of occupying the plains deceptive: Jiang Wei has entered a prepared battlefield, and the night assault is intended to make his exposed position fatal.

The night battle and successive defeats

The attack from above and below fails to overwhelm the Shu army. Deng Ai is forced to acknowledge defeat, and the major battle the next day drives the Wei forces back. The narrative presents Jiang Wei’s success as an inheritance from Kong Ming: he uses methods learned from his former strategist and what the account calls his almost magical military formulae. Military knowledge becomes not merely a matter of numbers or terrain but a continuing legacy that lets Jiang Wei overcome a carefully prepared ambush.

Sima Wang then tells Deng Ai that he, too, knows these strategies. The next engagement becomes a contest of wits and uncanny methods as well as force, but the renewed Wei effort also ends in defeat. Both Sima Wang and Deng Ai are routed; Deng Ai receives four arrow wounds while fleeing. The pair’s repeated losses make their response shift from trying to beat Jiang Wei in open combat to undermining his standing at court.

Rumors and the recall

Deng Ai and Sima Wang seek to damage Jiang Wei’s credibility with Liu Shan and the eunuch Huang Hao. They bribe Huang Hao, and rumors spread in Chengdu that Jiang Wei, dissatisfied with his authority, intends to defect to Wei. As the story gains currency, Huang Hao is able to petition Liu Shan to summon Jiang Wei home. The mechanism of defeat is political: after failing to stop the Shu army on the battlefield, Wei’s commanders make suspicion at court do what their forces could not.

Jiang Wei has been trying to bring the Wei army to battle, but the enemy holds back from open confrontation. The recall arrives while that campaign is still active. Once the order sends him home, however, Wei forces surge onto the battlefield to make the Shu withdrawal as arduous as possible. The contrast is sharp: the same army that would not offer the engagement Jiang Wei sought now presses hard against his retreat, hoping to turn a political order into a military disaster.

A controlled retreat and its aftermath

Jiang Wei manages the withdrawal with the care required to prevent an orderly return from becoming a rout. He protects his men with a strong rearguard, and Deng Ai, observing the formation, decides not to attack. The Shu army makes its way back safely. Thus the recall succeeds in removing Jiang Wei from the campaign, but not in destroying the force he commands.

On reaching Chengdu, Jiang Wei confronts Liu Shan about the reason for his recall. Liu Shan gives the lame explanation that the court feared Jiang Wei would exhaust himself. Jiang Wei answers that victory had been within reach and suspects that rumors, with Deng Ai behind them, caused the summons. Liu Shan has no real reply. Shortly afterward Jiang Wei returns to Hanzhong, ready to attack Wei again. The episode therefore closes not with reconciliation or a settled peace, but with the campaign delayed, the court’s distrust exposed, and Jiang Wei’s military purpose intact.
