On October 18 (according to other sources, 16), 1941, most of the Jews of Mariupol were executed by members of the Sonderkommando 10a, part of the Einsatzgruppe D unit, under the command of Heinz Seetzen. At first, the Jews were ordered to gather at a certain place in Maruipol, from where they were taken to the barracks on the outskirts of the city and held for a number of days. They were then taken to anti-tank trenches 7-10 kilometers from the city, near the Agrobaza (agricultural station) of the Perovsky sovkhoz. There they were forced to undress and sit on the edge of the trenches, where they were shot with machine guns. According to the sources, the number of victims ranged between 8,000 and (the apparently exaggerated number of) 20,000. Later, Jewish women married to non-Jewish men were killed at the same site, together with their children.
