In October 1919 it expanded further into the 8th Cavalry Division of Red Cossacks which in November of same year conducted a raid across the Denikin's Army rears. In April 1920 battled in the Northern Taurida Governorate against the Pyotr Wrangel's troops. Soon after the Polish-Ukrainian union treaty of Warsaw in 1920, the division participated in the Polish–Soviet War. During that campaign it reached the city of Stryi, but during a retreat of the Red Army, it was encircled and partially destroyed at Zbruch River.
