Thus Turgesh leaders were apprehensive of the Kutluk Khaganate and they sought alliances (like Yenisei Kirghiz and Tang dynasty) against the growing power of the east.
Turgesh khagan Suoge (also called Soko) had given his brother Zhenu ülüş (fief).
Kapagan’s son Inel, as well as his nephews Bilge (both future khagans) and Kul Tigin, were with Tonyukuk.
According to historian Lev Gumilev, Kapagan was not sure about the victory and Tonyukuk was given orders for attrition warfare.
