Unit: Einsatzkommando 2 / EK 3 / SK 1b (Einsatzgruppe A). Place on map: Riga (modern name: Rīga), Latvia. Date on map: 4 July 1941.

On 4 July 1941, the map places EK 2 / EK 3 / SK 1b, within Einsatzgruppe A in or near Riga (modern Rīga), Latvia. This record should be used first as a route/presence marker derived from the map, not as proof that a specific killing action took place on that exact date and in that exact locality. Einsatzgruppe A operated in the Baltic states and the area toward Leningrad. USHMM specifically names Kovno/Kaunas, Riga and Vilna/Vilnius among places where its members massacred Jews. The wider context is Operation Barbarossa and the rapid transition from persecution and occupation policy to mass murder by mobile SS and police killing units behind the German front. For publication, verify the locality and date against the Ereignismeldungen UdSSR, Yad Vashem's 'Untold Stories' locality project, USHMM locality articles/collections, and, where available, Yahad-In Unum material on killing sites and testimony. High-priority locality. USHMM identifies Riga as a major location for Einsatzgruppe A activity and describes later mass murder of Latvian Jews from the Riga ghetto; keep the map date separate from later massacre dates. Map note: Meerdere routes kruisen bij Riga; datum leesbaar.
