At least 48 Ukrainian families, 57 Polish families and 61 Jewish families lived in the town of Kisielin (the Jews were murdered in 1942). The estate was owned by Count Andrzej Olizar.

During the Second World War, the Poles in Kisielin were repeatedly attacked by the Ukrainian upholders. The biggest attack took place on Sunday 11.07.1943. About 2 weeks after this massacre, other inhabitants of Kisielin were kidnapped and killed: Wincenty Biesiaga, his son Józef, feldsher Leopold Dębski and his wife Anisja, and veterinarian Rudolf Nowicki.

These persons are buried in the Catholic cemetery in Kisielin. In 1993, the Association for the Commemoration of Poles Murdered in Volhynia erected three concrete crosses on the graves. The central cross, the largest one (2.6 m high) has an information plate with the inscription: "Catholic cemetery 1690-1943". The two smaller crosses (each 1.3 m high) are dedicated to the villagers murdered by the Ukrainian Insurgent Army in 1943. On the low cross to the right of the main cross is fixed a plaque with the inscription: "The late Agata Biesiaga / born 1895 / last parishioner / buried here / 30.07.1943 / asks for a Hail Mary". On the same cross to the left is a plaque with the inscription: "Kidnapped in July 1943 then / tragically died / Wincenty Biesiaga aged 53 / Jozef Biesiaga aged 14 / Leopold Dębski aged 56 / Anisja Dębska aged 54 / Rudolf Nowicki aged 50 / Honour their memory". The plaque on the left low cross was later changed, replaced by a brass plaque with the engraved inscription: "To the memory / of our Beloved Parents and Grandparents / long-time Kisielin doctor / Leopold Debski / Anja Debski née Czemierkin / who died somewhere in Volhynia in 1943 / Debski family". This change resulted in the loss of the coherent appearance of the commemoration and a reduction in the number of people commemorated.

Repair and renovation work was carried out on this commemoration in 2008 and 2011.
