"At almost each block, beside the men standing in line, bodies of… persons are lying. These are the victims of the night that have not lived to see the day. Even yesterday they were standing numbers at the roll call and today they lie, lifeless and motionless. Life is not important at the roll call. Numbers are important. Numbers tally. How horribly they are looking, as if returned from the war. These are the marks of yesterday's work."
Salmen Gradowski (1973). in Amidst a Nightmare of Crime. Oswiecim: Auschwitz State Museum Publication.
