The frontier in the south-west was extended slowly, in 1701 the Qing defeated Tibetans at the Battle of Dartsedo. The Dzungar Khanate conquered the Uyghurs in the Dzungar conquest of Altishahr and seized control of Tibet. Han Chinese Green Standard Army soldiers and Manchu bannermen were commanded by the Han Chinese General Yue Zhongqi in the Chinese expedition to Tibet (1720) which expelled the Dzungars from Tibet and placed it under Qing rule. At multiple places such as Lhasa, Batang, Dartsendo, Lhari, Chamdo, and Litang, Green Standard troops were garrisoned throughout the Dzungar war. Green Standard Army troops and Manchu Bannermen were both part of the Qing force who fought in Tibet in the war against the Dzungars. It was said that the Sichuan commander Yue Zhongqi (a descendant of Yue Fei) entered Lhasa first when the 2,000 Green Standard soldiers and 1,000 Manchu soldiers of the "Sichuan route" seized Lhasa. According to Mark C. Elliott, after 1728 the Qing used Green Standard Army troops to man the garrison in Lhasa rather than Bannermen. According to Evelyn S. Rawski both Green Standard Army and Bannermen made up the Qing garrison in Tibet. According to Sabine Dabringhaus, Green Standard Chinese soldiers numbering more than 1,300 were stationed by the Qing in Tibet to support the 3,000 strong Tibetan army.
