Li Daozong
Li Jing and Li Shiji believed that Illig Qaghan was stalling for time; they and Su Dingfang's vanguard combined and attacked Illig Qaghan's tent. Illig Qaghan fled to subordinate khan Ashina Sunishi (阿史那蘇尼失); Princess Yicheng of Sui, his wife, was killed. Illig Qaghan was soon captured by the Tang generals Li Daozong and Zhang Baoxiang (張寶相) and delivered to Chang'an. Turkic nobles largely surrendered to the Tang. The population surrendered to the Tang or Xueyantuo, or fled west to the Western Turkic Khaganate and the nearby kingdoms such as Qocho, Kucha and Tuyuhun.
