 As planned by Skorzeny, Operation Greif involved about two dozen German soldiers, most of them in captured American Jeeps and disguised in American uniforms, who would penetrate American lines in the early hours of the Battle of the Bulge to cause disorder and confusion.Skorzeny was well aware that under the Hague Convention of 1907, any of his men captured while wearing U.S. uniforms would be executed as spies and this possibility caused much discussion with Generaloberst Jodl and Field Marshal von Rundstedt.A handful of his men were captured and spread a rumour that Skorzeny personally was leading a raid on Paris to kill or capture General Eisenhower, who was not amused by having to spend Christmas 1944 isolated for security reasons.
