李光弼
Meanwhile, Guo Ziyi confronted a great force of a hundred thousand led by rebel commander Shi Siming. Although Guo had only ten thousand men he delayed Shi Siming's army until reinforcements could arrive. Shi Siming was tricked into thinking he would be ambushed if he moved against Guo and was delayed forty days. At that point commander Li Guangbi came to Guo's relief with ninety thousand men. The opposing forces clashed, resulting in few Tang losses, while the rebels suffered ten thousand casualties. Shi Siming quickly gathered up what was left of his force and retreated back to Fanyang, the rebels' stronghold. Li recommended Guo to Emperor Xuanzong, and Guo quickly asked the emperor for permission to launch an immediate counter-attack to destroy the remaining rebels, but Xuanzong refused him.
