The largest mass shooting perpetrated by the "Einsatzgruppen" took place on 29 and 30 September 1941 at Babi Yar, a ravine northwest of Kyiv, a city in Ukraine that had fallen to the Germans on 19 September. The perpetrators included a company of Waffen-SS attached to "Einsatzgruppe" C under Rasch, members of "Sonderkommando" 4a under SS-"Obergruppenführer" Friedrich Jeckeln, and some Ukrainian auxiliary police. The Jews of Kyiv were told to report to a certain street corner on 29 September; anyone who disobeyed would be shot. Since word of massacres in other areas had not yet reached Kyiv and the assembly point was near the train station, they assumed they were being deported. People showed up at the rendezvous point in large numbers, laden with possessions and food for the journey.
