The Qianlong Emperor then ordered genocide against the Dzungars and moved the remaining Dzungar people to the mainland while at the same time ordering his generals to kill all the men in Barköl or Suzhou . Qianlong divided their wives and children amongst the Qing forces , which consisted of Manchu Bannermen . Qing scholar Wei Yuan estimated the total population of Dzungars before the fall at 600,000 people , or 200,000 households . Oirat officer Saaral betrayed and battled against the Oirats . In a widely cited account of the war , Wei Yuan wrote that about 40 % of the Dzungar households were killed by smallpox , 20 % fled to Russia or Kazakh tribes , and 30 % were killed by the Qing army of the Manchu Bannermen , leaving no yurts in an area of several thousands li except of those who had surrendered . During this war Kazakhs attacked dispersed Oirats and Altays . Based on this account , Wen-Djang Chu wrote that 80 % of the 600,000 or more Dzungars ( especially Choros , Olot , Khoid , Baatud and Zakhchin ) were destroyed by disease and attack which Michael Clarke described as " the complete destruction of not only the Dzungar state but of the Dzungars as a people . " Historian Peter Perdue attributed the decimation of the Dzungars to an explicit policy of extermination launched by Qianlong , but he also observed signs of a more lenient policy after mid-1757 . Mark Levene , a historian whose recent research interests focus on genocide , has stated that the extermination of the Dzungars was " arguably the eighteenth century genocide par excellence . " It was not until generations later that Dzungaria rebounded from the destruction and near liquidation of the Dzungars after the mass slayings of Dzungars
