Poles had retreated from Baranowicze, abandoning German Imperial Army fortifications constructed there during World War I, and took defensive positions along the Jasiołda River.

The town of Bereza Kartuska was retaken by the Polish Army and, at the end of the Polish–Soviet War, ceded to Poland in the Peace of Riga signed by Soviet Russia (acting also on behalf of Soviet Belarus).
