So great was the confusion caused by Operation Greif that the U.S. Army “saw spies and saboteurs everywhere”. Perhaps the largest panic was created when a German commando team was captured near Aywaille on 17 December. Comprising Unteroffizier Manfred Pernass, "Oberfähnrich" Günther Billing, and "Gefreiter" Wilhelm Schmidt, they were captured when they failed to give the correct password. It was Schmidt who gave credence to a rumor that Skorzeny intended to capture General Dwight Eisenhower and his staff. A document outlining Operation Greif's elements of deception (though not its objectives) had earlier been captured by the U.S. 106th Infantry Division near Heckhuscheid, and because Skorzeny was already well known for rescuing Italian dictator Benito Mussolini (Operation Oak) and Operation Panzerfaust, the Americans were more than willing to believe this story and Eisenhower was reportedly “unamused” by having to spend Christmas 1944 isolated for security reasons. After several days of confinement, he left his office, angrily declaring he had to get out and that he didn't care if anyone tried to kill him.
