Yup,there was that one but another one they had was,I suspect,closer to this National Guard story.The crew got word that there was a spy at Headquarters in London.Hogan asked Kinch to contact London telling them that an assassin was gonna kill Hitler in an hour.The idea being that the spy would try to leave Headquarters to warn Hitler...and there's your spy.
Yes yes I even saw that one recently on ME TV. LoL.
