The following year another expedition, this one led by Major General Kolpakovsky, the victor at Uzun-Agach, invaded the Chinese province of Ili... Fearing that the rebellion might spill over into the new Russian territories east of Tashkent and south of Zake Balk hash. Kaufman had dispatched a preemptive strike against the rebels. The Russians treated the occupation of Ili, or Kuldzha, as a temporary measure and reassured the Chinese and the Europeans that the Tsar's forces would remain only until the Chinese were capable of re-occupying that and other rebellious western provinces. The Russians finally returned Kuldzha to Chinese control in 1883 after much diplomatic wrangling and the obtaining of concessions elsewhere.
