Following the onset of Operation Barbarossa, during the first 5 weeks of their shooting actions, the Einsatzgruppen squads targeted primarily male Jews. This changed on July 29, 1941, when Reinhard Heydrich himself, quoted at an SS meeting in Vileyka (Polish Wilejka), criticized their leaders for the low execution figures. It was therefore ordered that the Jewish women and children be included in all subsequent shooting operations.
