Zhuge Liang captured Chenfang

Kong Ming’s capture of Chencang is a turning point in the renewed northern campaign: after Hao Zhao withstands several carefully prepared assaults, Kong Ming takes the city by moving before his own reinforcements expect him to act. The success opens the route beyond the Qishan hills, brings the San Pass, Wudu, and Yinping within reach, and forces the Wei court to reconsider the danger from Shu.

The Northern Campaign and Its Objective

After Zhao Zilong’s burial with military and imperial honours, Kong Ming petitions the second ruler of Shu to continue the war against the north and fulfil the charge given him by the first ruler. The ruler agrees, and Kong Ming sets a force of three hundred thousand on the road to Chencang, with Wei Yan leading the army. Cao Zhen answers with a force of one hundred and fifty thousand, placing the giant Wang Shuang at the vanguard as he moves to defend Wei’s key passes.

Chencang is therefore more than a single besieged city: it stands on the route of the Shu advance, while its fortified position gives the defenders a chance to halt a much larger campaign. The contrast between the armies’ numbers does not make the outcome automatic. The city’s commander, Hao Zhao, turns the siege into a contest of preparation and response, compelling Kong Ming to look beyond a direct assault.

Hao Zhao’s Defence

When the Shu army arrives, it finds Chencang stoutly fortified and under Hao Zhao’s command. An outright attack fails, and Kong Ming is left considering how to overcome a defence that has already frustrated the army. Jin Xiang, one of his commanders and a friend of Hao Zhao, offers to approach him and discuss surrender. The first attempt fails when Hao refuses to negotiate and drives Jin Xiang away. On the second, Jin Xiang cannot even enter the city; Hao takes aim from the wall, and Jin has to flee.

Information from spies then gives Kong Ming a reason to expect a quick victory: the garrison may number only three thousand. He orders a hundred siege towers built to seize the apparently small force behind the walls. Hao Zhao counters with flaming arrows, destroying the towers and killing many of the men inside them. Kong Ming next orders battering rams for a mass attack, but Hao uses large rocks suspended on ropes to break them apart. When the Shu army tries tunnelling under the walls, Hao has a counter-tunnel dug and the miners are killed. Each method that should bring the siege closer to success instead demonstrates how thoroughly the defender has anticipated it.

The Change in Fortune

The approach of Wang Shuang’s vanguard adds pressure to an already difficult siege. Sent to counter him, the Shu troops suffer a defeat: Wang Shuang kills their commander, and the army loses confidence. Desertions follow, leaving Kong Ming in serious trouble. His commanders, especially Jiang Wei, recommend creating a diversion that could trap Cao Zhen and defeat Wang Shuang. Kong Ming accepts, and the army divides its forces.

At the same time, Kong Ming learns that Hao Zhao is seriously ill. He sends Wei Yan and Jiang Wei orders to attack Chencang when they see flames rise within the city, while telling them they have three days to prepare to leave. The instruction is deliberately out of step with the action he is taking: Wei Yan and Jiang Wei are still preparing when they reach the city and discover that Kong Ming has already captured it. He has set out at once with Zhang Bao and Guan Xing, rather than waiting the three days suggested by his orders.

The defenders, demoralized by Hao Zhao’s illness, offer little resistance. Supporters of Shu inside the city set the gates on fire, and the fighting that follows marks the collapse of the defence. Knowing that the city has fallen and that further resistance is hopeless, Hao Zhao dies on his sickbed. The capture thus comes not from overcoming his full defensive system by force, but from the sudden weakening of the garrison and the opening created by action inside the city.

Advance Beyond Chencang

Kong Ming immediately turns the capture into a territorial gain. His army seizes the San Pass, blocking Wei reinforcements from reaching Chencang. From the plains beyond the Qishan hills, he sends Jiang Wei to capture Wudu and Wang Ping to take Yinping. The sequence gives the victory wider strategic meaning: Chencang is secured, access for relief forces is restricted, and Shu troops move onward to additional positions.

The news reaches Cao Rui as several setbacks converge. He is told of Chencang’s fall and Hao Zhao’s death, of Kong Ming’s advance through the Qishan hills, and of Sun Quan’s declaration of himself as emperor. In distress, he summons Sima Yi for advice. Sima Yi argues that Wei need concern itself chiefly with Shu: he believes Wu’s movement is connected to its alliance with Shu and that Lu Xun will wait to see which side prevails. Cao Rui promotes Sima Yi and offers him the imperial seal of authority held by Cao Zhen; Sima Yi replies that he will obtain it himself. The immediate aftermath of Chencang is therefore not only a Shu advance but a shift in Wei’s command and preparations for a larger confrontation.

Strategic and Narrative Significance

The episode sets ingenious defence against adaptive command. Hao Zhao repeatedly defeats the siege towers, battering rams, and tunnel, making the city appear securely held; Kong Ming’s eventual success comes through timing and the defenders’ changed circumstances, not through another attempt to overpower the walls. The delayed orders to Wei Yan and Jiang Wei sharpen that reversal: their apparent three-day preparation period conceals Kong Ming’s immediate move with Zhang Bao and Guan Xing.

The capture also shows how a local result can alter the campaign’s geography and political stakes. Securing the San Pass limits Wei’s ability to reinforce the city, while the dispatch of Jiang Wei and Wang Ping extends Shu’s advance. At the Wei court, the loss prompts Cao Rui to elevate Sima Yi to a higher level of command. Chencang’s fall thus closes one contest over the city but opens the larger confrontation that follows.
