The history of the shadowy Werewolf guerrilla bands formed at end of the Second World War as the last desperate defence of Nazis. Founded by Heinrich Himmler in 1944 when it became clear Germany would be invaded, the Werewolf guerrilla movement was given the task of slowing down the Allied advance to allow time for the success of negotiations or wonder weapons. Staying behind in territory occupied by the Allies, its mission was to carry out acts of sabotage, arson and assassination, both of enemy troops and of defeatist Germans. Perry Biddiscombe has researched the movement exhaustively, and details Werewolf operations against the British, Russians and fellow Germans, on the Eastern and Western Fronts and in the post-war chaos of Berlin. Giving the lie to the established story of a cowed German population meekly submitting to defeat, this is a fascinating insight into what has been described as the death scream of the Nazi regime.
