Gao Xianzhi
Li Siye (李嗣業) (died March 2, 759), formally Prince Zhongyong of Wuwei (武威忠勇王), was a general of the Tang Dynasty. He was known to have fought valiantly at the Battle of Talas after the defeat of the primary army commanded by Gao Xianzhi, and his efforts allowed Gao to escape from the pursuit of the Abbasid Caliphate forces. Li Siye later died from battle injuries while fighting against rebel forces during the An Lushan Rebellion.
