Takes as its basis the detailed records of one squad from the Nazis' extermination groups and explores in its composition, its actions, and the methods by which it was trained to perform acts of genocide on an industrial scale. This book introduces us to men who killed without hesitation or apparent remorse for years on end.

The first UK publication of a widely admired study of a Nazi extermination squad, subtitled "Reserve Police Battalion 101 and the Final Solution in Poland". Drawing on records and interviews of a large proportion of the unit, a chilling picture emerges of how easily ordinary men can be trained to perform acts of genocide and murder.
