This atrocity was carried out on Saturday 10th June 1944 by soldiers of the Der Führer Regiment of the 2nd Waffen-SS Panzer Division Das Reich. On that day, without giving any explanation, they killed a total of 642 men, women and children, leaving only a few survivors. They then destroyed the entire village and to this day there is no universally accepted explanation for the massacre.
