Huang Zhong
Huang Zhong's army moved to burn the supplies of grain Cao Cao had at the North Mountain; his troops marched in the night, and at sunrise they reached the granary. Wei general Zhang He's army arrived before Huang Zhong could successfully burn the grain. Cao Cao then sent Wei general Xu Huang to intercept Huang Zhong and block his retreat. He succeeded, and Huang Zhong's army was surrounded. Zhao Yun's army dispatched to look for Huang Zhong after he had not returned by noon.
