On April 16, 1942 the commissar of the city of Vinnitsa Fritz Margenfeld ordered the Jews of Vinnitsa who had survived the massacres of 1941 to appear at the local stadium, allegedly for resettlement in a ghetto. After Jews of all ages and both sexes assembled at the stadium, a selection was carried out by Baltic auxiliaries who were stationed in Vinnitsa at this time. About 1,000 skilled workers were separated and sent to the city prison, while the rest were ordered to hand over the belongings they had brought with them. They were then driven to the Pyatnichany Forest and killed at the same murder site as the victims of September 1941. The number of victims of this massacre was about 5,000. The perpetrators of this mass murder were apparently members of the Reich Security Service, responsible for Hitler's personal security.
