On November 24, 1941, the Jews of Kozłowszczyzna, both natives and recent arrivals who had sought refuge there, were shot in the forest 1-1.5 kilometers south of the village. The pits had been dug earlier that day by local peasants. Estimates of the number of victims, some of whom came from the surrounding villages, range from 300 to 770. The discrepancy can be attributed to the fact that some accounts include the refugees in the number of victims, while others do not. In the following days, the Germans continued to search for Jews who had gone into hiding. Many of them were found and killed. That massacre was perpetrated by the German gendarmerie, who were assisted by Belorussian and Lithuanian policemen.
