In response to the Dzungar occupation of Tibet, a joint force of Tibetans and Chinese, sent by the Kangxi Emperor, responded. The Tibetan forces were under Polhanas (also spelled Polhaney) of central Tsang, and Kangchennas (also spelled Gangchenney), the governor of Western Tibet. The Dzungars were expelled from Tibet in 1720. They brought Kelzang Gyatso with them from Kumbum to Lhasa and he was enthroned as the 7th Dalai Lama.
