The plan was to assassinate Hitler during his morning exercise, as he walked unprotected to the "Teehaus" on the Mooslahnerkopf Hill from the Berghof residence. The scheme called for the SOE to parachute a German-speaking Pole and a British sniper into Austria. An "inside man" was recruited, the uncle of a prisoner of war named Dieser, who was a shopkeeper living in nearby (20 km) Salzburg, identified as "Heidentaler", who was vehemently anti-Nazi. "Heidentaler" would shelter the agents and transport them to Berchtesgaden disguised as German mountain troops, from where they would make the approach to the vantage point for the attack.
