NN - Deportees sentenced to vanish into the night and fog (1941 - 1944)
The German expression NN means ”Nacht und Nebel”, or ”Night and Fog”.
This expression reflects Hitler's decision to sentence all opponents to the Nazi regime, men and women, to die in isolation and with no defence. The special treatment reserved to these deportees also aimed to eliminate them totally, i.e. to erase any trace of their existence and their death, like shadows swallowed up by the night and fog.
