裴炎
In 679, Turkic chieftain Ashide Wenfu rebelled. Protectorate general Xiao Siye, a noble from Lanling Commandery, was defeated by Ashide. Pei then took over the command from Xiao and decisively won a battle against the Turks in an ambush. Ashide fled. Not long after the first defeat, Ashide Wenfu gathered his troops and united them with the troops of another chieftain Ashina Funian. Pei saw the distrust and suspicions between the two chieftains and exploited this weakness by driving a wedge between them. Eventually, Ashina Funian murdered Ashide Wenfu out of the fear of Tang's revenge against him. When Funian was brought to the Tang court, he was executed regardless of the fact that he surrendered his troops. Pei had promised Ashina that he would not be put to death, however, the court did not respect Pei's promise. Due to this incident, Pei retired. Ashina's death, according to New Book of Tang, was a scheme against Pei Xingjian by his very own clansman Pei Yan who was jealous about his victories in the West.
