On July 17 or 18, 1941, the German Gendarmerie, assisted by the local police, assembled the Jews of Dubinowo at the old Beit Midrash. The Nazis killed four Jewish men on the spot and forced the rest of the Jews to crawl into the new Beit Midrash, which was subsequently locked. The imprisoned Jews were subjected to abuse and beatings; thus, the perpetrators ordered them to lie face down and stomped on their bodies. They then selected 20 Jewish men, led them toward the Jewish cemetery, about 300 meters southeast of the village, and shot them in an adjoining field. The victims were buried in a pit that had been dug in advance. The rest of the Jews were returned to their homes.
