Einsatzgruppe D entered Budyonnovsk in August 1942 and Einsatzkommando 12 established its headquarters there in September 1942 at no. 52 Pushkin Street. The Einsatzkommando was ethnically mixed, half of its members were German and half were people from the Caucasus. Local Jews were ordered to move far from the frontline. They had to appear on September 8, 1942 at the Einsatzgruppe headquarters.
Between 70 and 100 people showed up, consisting of Jews of all ages,including young children and the elderly. The Jews had food and some of their possessions with them, believed the occupiers' claim that they were going to be evacuated to a safer place.. Local policemen and non-German members of the Einsatzkommando surrounded the civilians and ordered them to hand over their belongings and their food to the local police. Then several trucks arrived to transport the Jews. Non-German members of the SD and local policemen threw the food and Jewish possessions to the ground and then mounted the trucks to guard the Jews there on their way to an anti-tank trench 5-6 kilometers from the town. There the Jews were pushed by the Germans toward the trench. In tears, the Jews were forced to undress. Mothers begged for mercy for their children's lives, but the SD and the German members of the Einsatzkommando showed no mercy. They forced the Jews to face the pit and then shot the Jews in the head with pistols. The bodies fell into the pit. The clothes of the victims were thrown onto the trucks and taken to the basement of the headquarters. This tyoe of murder operation were carried out mainly in September and October 1942. After a pit was full with bodies, new pits were dug by local policemen. It was not only Germans shot the Jews in the head, but also local policemen and non-German Einsatzkommando members.
The Germans and their collaborators shot a total of 1,628 people,most of whom were Jews.The bodies were found in a number of anti-tank trenches in the town.

After the occupation of the town, Einsatzkommando 12 established its headquarter in Budyonnovsk on Pushkin Street, no. 52. Immediately after the establishment of this headquarters in August 1942, the Germans and the auxiliary police started to arrest Jews. Usually, there were between 45 and 70 Jewish civilians. They were held in the cellar of the building and they had to wait there until the next morning. Their belongings were taken by the local policemen and brought to a German storeroom. On the next morning the Jews were ordered to go out to the yard. There were usually one or more trucks there. The Jews had to enter the Wehrmacht’s trucks and were taken to the airfiled or to the outskirts of Budyonnovsk, where they had to undress, and then they were shot to death. This process was repeated on a number of occasions. After the liberation of the town, 72 bodies were found in the yard of no. 52 Pushkin Street. It is probable that the Red Army arrived sooner than the Germans and the auxiliary police expected and, as a result, the Jewish victims whom they were planning to shoot were shot spontaneously in the yard of the headquarter. The same thing is possible in regard to the 42 dead bodies that were found in ditches in the town park.
