The group was founded in December 1940 and led by Abraham Gancwajch, a Jewish Nazi Collaborator.
In April 1942 many members of the Group 13 were executed by the Germans in Operation Reinhard. Gancwajch and surviving members of the group later re-emerged posing as Jewish underground fighters, though in reality they were hunting for Poles hiding or otherwise supporting the Jews. After closing the Jewish Gestapo, Gancwajch stayed in Warsaw outside the ghetto, where he continued working for the Nazis.
