固始汗
The Geluk sect asked for help Törü Bayikhu (Güshi Khan), the leader of the Khoshuud tribe of the Oirat confederation. In 1636, Törö Bayikhu led the Khoshuud and the Dzungars to Tibet. In the next year a decisive war between Tsoghtu Khong Tayiji and Törü Bayikhu ended in the latter's victory and Tsoght was killed.
