In late April 1920, Polish forces began their offensive towards Kiev (see Kiev Offensive (1920)). On May 3, the 19th Relief of Lwów Infantry Regiment captured Nemyriv, and a few days later it was transported to the area of Samhorodek (near Koziatyn). There, it clashed with the 1st Cavalry Army (Soviet Union) of Semyon Budyonny, losing 9 officers and 497 soldiers.
