The Bila Tserkva massacre was the World War II mass murder of Jews, committed by the Nazi German Einsatzgruppe with the aid of Ukrainian auxiliaries, in Bila Tserkva, Soviet Ukraine, on August 21–22, 1941. When the Jewish adult population of Bila Tserkva was killed, several functionaries complained that some 90 Jewish children were left behind in an abandoned building, and had to be executed separately. The soldiers reported the matter to four chaplains of the Wehrmacht, who passed along their protests to Field Marshal von Reichenau; it was the only time during World War II that Wehrmacht chaplains tried to prevent an Einsatzgruppen massacre, but Paul Blobel's verbal order was direct and decisive.
