Zhang Xun
Linghu Chao refused to retreat, and returned to Yongqiu to continue the siege. Zhang Xun was running low on lumber. He made Linghu Chao an offer: if Linghu Chao would move back 30 miles, and allow Zhang Xun and his men to escape, the fortress would be his. The battle-worn Linghu Chao immediately accepted. He moved his troops and supplies back 30 miles, but he did not remove the wooden huts and tents. Zhang Xun immediately ordered his troops to tear down the huts and tents, and bring the lumber back into the fortress. By the time Linghu Chao figured out Zhang Xun's plan, it was too late.
