李光弼
Faced with a siege that he could not fight out of, An Qingxu sought aid from Shi Siming, who led an army south from Fanyang and engaged Tang forces in spring 759, and during the middle of the battle, both Tang forces and Shi's forces panicked and scattered—with most of Tang forces completely scattering and pillaging the surrounding areas before fleeing back to their own circuits, with the exception of Li Guangbi and Wang, who were able to gather their forces and withdraw. In fall 759, with Yu blaming Guo for the collapse, Emperor Suzong transferred the command of the Shuofang troops that Guo commanded to Li Guangbi. With Guo's command style being far more relaxed than Li Guangbi's strict style, the Shuofang army was initially displeased, and the general Zhang Yongji (張用濟) considered forcibly ejecting Li Guangbi and demanding Guo's restoration; when Li Guangbi found out, he arrested and executed Zhang. Li Guangbi was also made the deputy supreme commander of the armed forces and in effect in command of the entire Tang army command structure, as the supreme commander was Emperor Suzong's son Li Xi (李係) the Prince of Zhao, whose title was honorary.
