text: Saqal attacked the Tang city of Qiuci (Kucha) in 708 and inflicted a defeat on the Tang in 709. However Saqal's younger brother Zhenu rebelled and sought military support from the Qapagan Khaghan of the Second Turkic Khaganate in 708. Qapaghan Khagan defeated the Turgesh in 711 in the Battle of Bolchu, and killed both Saqal and Zhenu. The defeated Turgesh fled to Zhetysu. In 714 the Turgesh elected Suluk as their khagan.
