This humiliation only determined the Kangxi Emperor to expel the Dzungars from Tibet once and for all and he set about assembling and dispatching a much larger force to march on Lhasa, bringing the emperor's trump card the young Kelzang Gyatso with it. On the imperial army's stately passage from Kumbum to Lhasa with the boy being welcomed adoringly at every stage, Khoshut Mongols and Tibetans were happy (and well paid) to join and swell its ranks. By the autumn of 1720 the marauding Dzungar Mongols had been vanquished from Tibet and the Qing imperial forces had entered Lhasa triumphantly with the 12-year-old, acting as patrons of the Dalai Lama, liberators of Tibet, allies of the Tibetan anti-Dzungar forces led by Kangchenas and Polhanas, and allies of the Khoshut Mongol princes. The delighted Tibetans enthroned him as the Seventh Dalai Lama at the Potala Palace.
