In late December 1941, several hundred inmates of the Kharkov Ghetto, which had been set up in the area of the former tractor and machine tool plants, were taken out of the ghetto, ostensibly for work in other Ukrainian cities. They were driven several kilometers southeast, to a ravine known as Drobitskiy Yar, and shot dead there. In early January 1942, members of Sonderkommando 4a of Einsatzgruppe C took the bulk of the inmates of the Kharkov Ghetto, a total of about 10,000-15,000 people (a figure derived from survivor testimonies, Soviet reports, and the documents of the German perpetrators), to Drobitskiy Yar, either by truck or on foot, and shot them dead.
