The Wolf's Lair was Adolf Hitler's first Eastern Front military headquarters in World War II.
The headquarters was located in the Masurian woods, near the village of Görlitz, about 8 kilometres east of the town of Rastenburg, in present-day Poland. The central complex and the Führer's bunker were surrounded by three security zones guarded by two Schutzstaffel units: the SS-Begleitkommando des Führers, and the Reichssicherheitsdienst.
The Wehrmacht's armored Führerbegleitbrigade was held in readiness nearby but, as a part of the Heer's elite Großdeutschland Division, was used to counter-attack Red Army break-throughs in Army Group Centre's front and rescue cut-off Heer, Luftwaffe Fallschirmjager, and SS panzer troops.
