Ultimately a sniper attack was considered to be the method most likely to succeed. In Summer 1944, a German who had been part of Hitler's personal guard at the Berghof had been taken prisoner in Normandy. He revealed that at the Berghof, Hitler always took a 20-minute morning walk at around the same time (after 10:00). Hitler liked to be left alone during this walk, leaving him unprotected near some woods, where he was out of sight of sentry posts. When Hitler was at the Berghof, a Nazi flag visible from a cafe in the nearby town was flown.
