The cemetery contains graves of Polish and Bolshevik soldiers from 1920. Resting in them are 6 unknown Poles and 5 unknown Soviets who fell in a skirmish that was victorious for the Poles in 1920 near Ostrówek. Initially, these soldiers were buried on two sides of the fence separating parts of the cemetery. After field works in 1991, during which the area of the necropolis was enlarged and a new fence was made, the graves of Polish and Bolshevik soldiers were placed next to each other. In 2005, thanks to the efforts of the Council for the Protection of Struggle and Martyrdom Sites and at its expense, a new commemoration was placed on the soldiers' graves, visually linking the graves into a single whole. It consists of five elements - an irregular stone in the shape of the date "1920", two simple crosses without inscriptions - a Catholic and an Orthodox one - and two square boulders with inscriptions. The inscription commemorating Polish soldiers reads: "Here rests 6 unknown soldiers of the Polish Army killed in the battle against the Bolsheviks in 1920. / Honour their memory / Government of the Republic of Poland and Compatriots / 2005". Below this is the same inscription in Ukrainian. The inscription commemorating Soviet soldiers: "Here lie 5 unknown Red Army soldiers killed in 1920. / 2005 / May they rest in peace". Below is the same inscription in Ukrainian.
