Remember, the Holocaust-Proper kicks off with Einsatzgruppen following the Wehrmacht, and under orders to exterminate communists and Jews.
This they did, from the beginning.
I'll pick up the data starting today, and take it from the Holocaust Chronicle:
"July 31, 1941: Hermann Goring instructs SS Reich Security Service chief Reinhard Heydrich by letter to evacuate and eliminate all European Jews presently in German-held territory.
The letter mentions "complete solution" to European Jewry.Late July 1941:
"Germans establish a Jewish ghetto at Dvinsk, Latvia.
July-August 1941:
"Tens of thousands of Jews are murdered throughout the western Soviet Union, Lithuania, Romania, and Latvia.
The killers are German Einsatzgruppen, Romanian troops and militia, Ukrainian peasants, and Lithuanian civilians."
Reinhard Heydrich:
"An Einsatzgruppe D member about to shoot a Jew kneeling at a mass grave in Vinnitsa, Ukrainian SSR, Soviet Union, in 1942.
The photograph is inscribed: The last Jew in Vinnitsa.":
