Many of you already know how some English-speaking German's had infiltrated our lines during the Bulge. For those of you who aren't aware of this, here's some brief facts.
Skorzeny successfully infiltrated his battalion of disguised, English-speaking Germans behind the Allied lines. Although they failed to take the vital bridges over the Meuse, the battalion's presence produced confusion out of all proportion to their military activities, and rumours spread like wild-fire. Even General Patton was alarmed and, on December 17, described the situation to General Eisenhower as "Krauts... speaking perfect English... raising hell, cutting wires, turning road signs around, spooking whole divisions, and shoving a bulge into our defenses".
Here's a great tidbit from the history. I hope it will give you a chuckle.
Checkpoints were soon set up all over the Allied rear, greatly slowing the movement of soldiers and equipment. Military policemen drilled servicemen on things which every American was expected to know, such as the identity of Mickey Mouse's girlfriend, baseball scores, or the capital of Illinois. This latter question resulted in the brief detention of General Omar Bradley himself; although he gave the correct answer—Springfield—the GI who questioned him apparently believed that the capital was Chicago.
