張勲
Zhang Xun noticed that if Yongqiu remained in An Lushan's control, Suiyang would not be safe for much longer. As a result, he led an army of around 2,000 men to besiege the weakly-defended Yongqiu. At this time, Linghu Chao had imprisoned a few hundred loyal Tang soldiers within the fortress. To Zhang Xun's luck, these prisoners were able to escape (probably with the help of civilians or other uncaptured loyal soldiers), and caused massive chaos within the fortress. Zhang Xun took this opportunity to besiege the fortress. Yongqiu fell to Zhang Xun very quickly, and Linghu Chao escaped.
