Chen Zao 陳造

In Chapter 94 of the Romance, Cao Zhen pursued the retreating Shu army along two routes and lost both of his vanguards: the vanguard Cao Zun was cut down by Wei Yan, and the deputy vanguard Zhu Zan was run through by Zhao Yun's spear. Unable to stop grieving, Cao Zhen asked the court for reinforcements, and in Chapter 95 the Wei ruler Cao Rui made Zhang He the vanguard and sent him out together with Sima Yi, and gave Xin Pi and Sun Li 50,000 troops to assist Cao Zhen.

Hearing that Jieting and Lieliu City had both been lost, Zhuge Liang lamented that this was his own fault and prepared to withdraw. He told Guan Xing and Zhang Bao merely to beat drums and raise war cries on the byways of Mount Wugong to alarm the Wei troops, and he had Ma Dai and Jiang Wei guard the rear, first lying in ambush in the mountain valleys and withdrawing their own troops only after all the other forces had gone. Romance, Ch. 95 §37–39

On hearing that Zhuge Liang was withdrawing, Cao Zhen hurriedly led his troops in pursuit. A cannon boomed once behind a hill, and Shu troops came swarming over the hills and fields, led by the generals Jiang Wei and Ma Dai. As Cao Zhen, greatly alarmed, hastily pulled back his troops, his vanguard Chen Zao had already been cut down by Ma Dai. Cao Zhen fled back with his troops like a scurrying rat, and the Shu troops all returned to Hanzhong through the night. Romance, Ch. 95 §52

Afterwards Cao Zhen and Guo Huai retook the three commanderies and claimed it as their own achievement. Romance, Ch. 95 §58
