The Werwolf is thought to have had about 5,000 members. Both the British and Americans were attacked by them. Major John Poston, who had been with Field Marshal Montgomery in the desert, in Sicily and in northwest Europe, and served as a liaison officer for the field marshal, was ambushed in his jeep and killed. On 24th March, 1945, the Lord Mayor of Aachen was assassinated by Werewolf agents. He was not the only US appointed official to die at the hands of the partisans, but he was the most important. The Commander of the 3rd Armored Division, General Maurice Rose, was allegedly assassinated by Werewolf agents in Padeborn.
Radio Werwolf bragged that "the arm of the National Socialist Party was long and that its agents, the Werwolf, were vigilant, ruthless killers." The radio station broadcast a call to arms claiming itself to be the organization of National Socialist Freedom Fighters. The radio station vowed that the Werwolf would never bow to the enemy and would employ every means to damage the enemy. Perhaps more important, the radio station told the German people that the Werwolf was employing its own judicial system to decide the life and death of German traitors.
