A good summary of the Werewolf issue - not quite as negligible as many authors indicate nor as sinister as thriller writers make it.
Most incidents detailed occurred before German surrender and were therefore acts of war, though sometimes carried put by un-uniformed personnel. This is inevitably the story of a series of isolated groups with little overall strategy or command. The plans for partisan warfare were not as thorough as other Nazi initiatives - perhaps no high ranking officials wanted to get in front on this because it presumed military defeat - and "defeatism" was ironically one of the things for which "Werewolves" were supposed to punish their fellow Germans.
The post-war incidents are even more isolated and unfocused than the wartime actions, and the organized groups described are all centered around individual conspiracy theorists or megalomaniacs. Some non-lethal bombings in Nuremberg and Stuttgart aimed at de-nazification officials and venues.
The importance of "Werewolf" was probably more psychological than physical (though several hundred wartime casualties are attributed to it), enhanced by Nazi "Werewolf radio" broadcasts in April 1945. Allied forces were less likely to trust any German and no doubt imagined the Werewolf numbers greater than they actually were.
