Nazi Germany used Werwolf, as the mythical creature's name is spelled in German, in 1942–43 as the codename for one of Hitler's headquarters. In the war's final days, the Nazi "Operation Werwolf" aimed at creating a commando force that would operate behind enemy lines as the Allies advanced through Germany itself. Two fictional depictions of "Operation Werwolf"—the US television series True Blood and the 2012 novel Wolf Hunter, by J.L. Benét—mix the two meanings of "Werwolf" by depicting the 1945 diehard Nazi commandos as being actual werewolves.
