I would like to remind everyone that Soviet Russia was originally allied with Hitler and this only changed later in the war.
Between 1941-1945 in non-Nazi German occupied areas, 621,637 people died, and were documented in the Soviet #Gulag system.

A 1995 study estimated the total to have been closer to 1 million Russian civilians in the Gulag and Prison system from 1941-45.

In Poland, the Soviets were complicit in the deportation of at least 500,000 ethnic Poles to camps. @rusembassynl
