On December 10, 1941 the Krymchaks were ordered by the city administration of Feodosiya to appear on December 12 at Sennaya Square in order to be relocated to another part of the city. About 300 Krymchaks appeared at the collection point; others went into hiding. Only 9 Krymchak families (42 persons) of artisans with their families were temporarily spared by the Germans in order to fill German labor needs. The rest, guarded by the policemen (from an Order Police battalion) and the Russian auxiliary militia, were taken by truck to the former supplementary poultry farm of the city hospital, that was located several hundred meters from the Mechanik Factory and shot to death by members of Sonderkommando 10b. Military policemen (Feldgandarmerie) from Field Commandant's Office 810, as well as Russian auxiliary policemen, took an active part in this shooting.
According to a report of the field commandant's office, during January and February 1942, 36 Jews who had gone into hiding and, apparently, also Jews from mixed marriages (mainly children) were shot to death at the anti-tank site. On March 5, 19, and 23, 1942, during roundups of Jews in hiding, another 66 Jews were caught and shot to death by members of Sonderkommando 10b and the Wehrmacht at the same murder site. According to German sources, in April 1942 some Jews (including women and children) were loaded into gas vans and asphyxiated during the ride from the SD headquarters in Feodosiya to this site. Their bodies were disposed of there.
