In June 1941, the German army invades the USSR. Following behind are the Einsatzgruppen, 3000 men grouped into four "intervention groups" each given a designated geographical region, sent to exterminate Jews and enemies of the Reich. Within a few months, the genocide work is accomplished. In December 1941, the Baltic countries are declared 'Judenfrei" free of Jew. Who were these men who organized and carried out the mass assassination of Jews, Gypsis and Soviet prisoners?
