Battle of Wakou Pass

The Battle of Wakou Pass is a contest between Zhang Fei and Zhang He in which deception, patience, and knowledge of the terrain decide who controls the pass. Zhang Fei first breaks Zhang He’s attack with a coordinated ambush, then turns apparent drunkenness into bait, and finally finds a way around the fortified position. The episode makes his unruly public image part of his command strategy: what looks like loss of discipline becomes a means of inducing the enemy to act on a false assumption.

Background and Forces

Zhang He brings thirty thousand men to establish three hill forts for the defense of his base, then advances with another fifteen thousand. Zhang Fei and General Lei Tong recognize that the area offers an opportunity for an ambush. They plan for Zhang Fei to charge and occupy the enemy’s attention while Lei Tong secretly leads a force around to the rear. The arrangement depends on timing and coordination rather than a direct contest of strength: Zhang Fei’s attack is intended to create the opening for Lei Tong’s surprise approach.

The first maneuver succeeds. Zhang He’s army is badly beaten, and he retreats to one of his camps with Zhang Fei and Lei Tong in pursuit. He then fortifies his main camp and refuses to come out, despite Zhang Fei’s daily challenges. The fighting gives way to a long standoff, with Zhang He holding behind his defenses and Zhang Fei trying to make him abandon them.

The Drunkenness Stratagem

Fifty days pass. Zhang Fei spends his days drinking and shouting insults at Zhang He from outside the camp. When Xuande hears of this behavior, he is distressed; Zhang Fei’s history of destructive drinking makes it seem like a lapse rather than a plan. Kong Ming, however, proposes sending him fifty barrels of the best wine from Chengdu, explaining that Zhang Fei is trying to make the enemy believe he has lost his judgment. The gift sustains the appearance that concerns Xuande, while giving Zhang Fei an opportunity to use it deliberately.

Zhang He takes the performance as evidence that Zhang Fei will be too drunk to resist and decides to attack at night. He sees Zhang Fei apparently drinking amid lamps and charges directly at him. But the figure he strikes is a straw man made to resemble Zhang Fei. The decoy has drawn Zhang He into the camp, where bombardments erupt around his force; the real Zhang Fei then appears and the situation turns against the attackers. The stratagem works because Zhang He mistakes a carefully staged display for an accurate picture of his opponent’s readiness.

Reversals and the Capture of the Pass

Zhang He’s position worsens when he looks for help from his other two camps and sees that they too have been captured and his men routed. He fights his way out and reaches Wakou Pass after losing two thirds of his force. Cao Hong responds furiously and orders him to return to battle. Zhang He goes back the following day, ashamed, and encounters troops led by Lei Tong. During the fighting, Zhang He feigns retreat and kills Lei Tong when he pursues. Zhang Fei hurries to confront Zhang He, but does not fall for the same trick. Their ensuing struggles remain inconclusive: both commanders attempt ambushes and deceptions, and Zhang He remains securely established in the camp guarding the pass.

The final opening comes from a different kind of observation. Zhang Fei notices traders travelling along a steep hillside path and learns from them that it provides a narrow route behind the pass. He sends Wei Yan with a picked force to move into position without alerting Zhang He, then attacks from the front. Zhang He arms himself to meet the assault, only to hear that fires and attacks have broken out behind him. The forces striking from both directions overwhelm his defense. Of the men left after the battle, only ten escape with Zhang He and make their way back to Cao Hong’s camp.

Consequences and Narrative Significance

Cao Hong wants Zhang He executed after the defeat, but others dissuade him. He reluctantly gives Zhang He another five thousand men, this time for an advance toward Jiameng Pass and the defense of Hanzhong. The immediate result is therefore more than the loss of men: Zhang He’s position at Wakou Pass has been broken, while the surviving commander is redirected to a new task despite his failure.

The battle develops through successive changes in what each commander can know and control. Zhang He first avoids Zhang Fei’s taunts by staying behind walls; later he acts on the misleading evidence of the drinking display; finally, the traders’ knowledge of a hillside route lets Zhang Fei attack beyond the front Zhang He has secured. The episode also contrasts the first successful ambush, in which Lei Tong’s concealed force supports Zhang Fei’s charge, with the later double attack that captures the pass. Zhang Fei wins not through a single decisive clash but by changing the terms of engagement until Zhang He’s defenses no longer protect him.

Event Metadata

The account belongs to the main narrative and is presented through impersonal third-person narration. Its decisive revelations are practical rather than personal: Zhang Fei’s apparent drunkenness is a feint, Zhang He’s other camps have fallen during his attack, and a narrow hillside path gives Zhang Fei access to the rear of Wakou Pass.
