The Werewolf Principle
Lessons of History, Continued: From a review of "Werewolf! The History of the National Socialist Guerrilla Movement, 1944-1946" ;
What did the Werwolf do? They sniped. They mined roads. They poured sand into the gas tanks of jeeps. (Sugar was in short supply, no doubt.) They were especially feared for the "decapitation wires" they strung across roads. They poisoned food stocks and liquor. (The Russians had the biggest problem with this.) They committed arson, though perhaps less than they are credited with: every unexplained fire or explosion associated with a military installation tended to be blamed on the Werwolf. These activities slackened off within a few months of the capitulation on May 7, though incidents were reported as late as 1947. ...
Goebbels especially grasped the possibility that guerrilla war could be a political process as well as a military strategy. It was largely through his influence that the Werwolf assumed something of the aspect of a terrorist organization. Where it could, it tried to prevent individuals and communities from surrendering, and it assassinated civil officials who cooperated with the Allies. Few Germans welcomed these activities, but something else that Goebbels grasped was that terror might serve where popularity was absent. By his estimate, only 10% to 15% of the German population were potential supporters for a truly revolutionary movement. His goal was to use the Werwolf to activate that potential. With the help of the radical elite, the occupiers could be provoked into savage reprisals that would win over the mass of the people to Neo-Nazism, a term that came into use in April 1945.

The Werewolves specialised in ambushes and sniping, and took the lives of many Allied and Soviet soldiers and officers -- perhaps even that of the first Soviet commandant of Berlin, General N.E. Berzarin, who was rumoured to have been waylaid in Charlottenburg during an incident in June 1945. Buildings housing Allied and Soviet staffs were favourite targets for Werewolf bombings; an explosion in the Bremen police headquarters, also in June 1945, killed five Americans and thirty-nine Germans. Techniques for harassing the occupiers were given widespread publicity through Werewolf leaflets and radio propaganda, and long after May 1945 the sabotage methods promoted by the Werewolves were still being used against the occupying powers.
Although the Werewolves originally limited themselves to guerrilla warfare with the invading armies, they soon began to undertake scorched-earth measures and vigilante actions against German `collaborators' or `defeatists'. They damaged Germany's economic infrastructure, already battered by Allied bombing and ground fighting, and tried to prevent anything of value from falling into enemy hands. Attempts to blow up factories, power plants or waterworks occasionally provoked melees between Werewolves and desperate German workers trying to save the physical basis of their employment, particularly in the Ruhr and Upper Silesia.
Several sprees of vandalism through stocks of art and antiques, stored by the Berlin Museum in a flak tower at Friedrichshain, caused millions of dollars worth of damage and cultural losses of inestimable value. In addition, vigilante attacks caused the deaths of a number of small-town mayors and, in late March 1945, a Werewolf paratroop squad assassinated the Lord Mayor of Aachen, Dr Franz Oppenhoff, probably the most prominent German statesman to have emerged in the occupied fringes over the winter of 1944-45.
