First, for those unfamiliar with Columbus, GA (Ft Benning). Right across the Chattahoochee river from Columbus is Phenix City, Alabama. Back during WWII Phenix City was were.....uh....all the action was. (And yes, that's how they spell it, Phenix.)
So the story goes that the night before Patton's army was suppose to ship out so many of his troops were imprisoned over in Phenix City that it threatened his deployment. So they say, he drove a tank to the middle of the bridge, between Columbus and Phenix City and demanded the police release all his troops.
