Li Siye - During The Battle of Talas

During The Battle of Talas

In 751, Li Siye served under Gao Xianzhi, who had been made the military governor of Anxi by that point, in a campaign west against the Abbasid Caliphate that climaxed in the Battle of Talas. The Tang and Abbasid forces were locked in battle for several days, before Qarluq forces turned against Gao, causing Gao's forces to collapse, with only several thousands surviving among 20,000-30,000. Gao tried to regather his troops to battle further, but Li Siye pointed out to him that continued battle would mean annihilation of the remaining troops, urging Gao to retreat. Gao agreed, and began a retreat. Li Siye served as the rearguard and was able to successfully keep the path of flight open -- as Gao's associate Bahanna (拔汗那) forces crowded the narrow escape path, Li Siye battered the Bahanna soldiers and livestock with a staff, killing many -- and fight off Abbasid pursuers. For this valiant effort, he was promoted in his general rank under Gao's recommendation. However, Duan Xiushi, also serving under Gao, rebuked Li Siye for advocating what effectively meant the abandonment of any soldiers who might have been scattered. Li Siye, impressed with Duan's fortitude, made Duan his own assistant upon return to Anxi.)
