Tsewang Rabtan and his commanders, such as
Lobsangsür invaded the upper reach of the
Irtysh river, and attacked the nomadic camps of the
Jüz, specifically, the Middle Jüz and the Senior Jüz on 1723. Another major Dzungar army attacked to the
Chu, Nura, Shelek and
Talas rivers,
Balkash Steppe—as they swiftly occupied the regions. This allowed for the invasion of
Jetisu and
Southern Kazakhstan and sacking their territory. Afterwards, a Kazakh militia fought the Dzungars, in which the Kazakhs were expulsed, a Kazakh militia led by an unknown batyr battled the Dzungar army led by Lobsangsür at the city of
Sayram and the Kazakhs were defeated again on
Tashkent. This led to its capture and plunder by the Dzungars. The Kazakhs retreated to Khara Murut, where they, again, suffered defeat; the Dzungars sacked the city, in which Bolat Khan was killed and Samake Khan fled. The Dzungars then swept through the
Fergana Valley, which the Dzungars captured
Khujand,
Andijan and
Samarkand. They later captured more cities throughout the rivers of
Chirchiq,
Arys and
Borolday, consolidating their occupation. ==In national history==
