Paul Zapp was, until 1942, head of Einsatzkommando 11a. He had been to Sebastopol to try to get one of EG D's gas vans assigned to him, and he stated:
...on this occasion I was present at the extermination of Jews - men and women - in gas vans. The victims had to strip naked and were herded into the vans. The doors were closed so that the van was hermetically sealed. The engine was started and left running. After only a short time, no more signs of life came from those inside. The van was then driven to a ditch outside of town. The doors were opened and the bodies thrown into the ditch.
