A few Torghut nobles followed Toro Baikhu Gushi Khan to Qinghai Lake (Koke Nuur), becoming part of the so-called Upper Mongols.
Due to harsh treatment by Russian governors, most Torghuts eventually migrated back to Dzungaria and western Mongolia, departing en masse on January 5, 1771.
The size of the departing group has been variously estimated between 150,000 and 400,000 people, with perhaps as many as six million animals (cattle, sheep, horses, camels and dogs).
[4] Beset by raids, thirst and starvation, approximately 85,000 survivors made it to Dzungaria, where they settled near the Ejin River with the permission of the Qing Emperor.
The Governor therefore ordered the Kalmuks to gather the harvest, but, as they were nomads who despised agriculture, they refused, and when threats were offered, they all decamped, and no persuasions could bring them back.
It is much to be regretted that the Russian Government did not act upon the information contained in his reports, and either give some active support to the Chinese authorities, or itself occupy the country to prevent bloodshed.
In the meantime both Solons and Sibos were being attacked and plundered, and were obliged to make peace with the insurgents, so that only Ili, Khorgos, Losigun, and Suidun, remained in the hands of the Mantchus.
