Operation Pistol and battle of the Bulge


If you read the Pistol reports which are on Wikipedia you will find one SAS report which refers to one SAS patrol,not my fathers by the way, seeing german trains heading east to germany with American captured vehicles on flat cars. Could this have been for use in the Battle of The Bulge attack that caught the Americans by surprise. They used used American tanks/trucks etc to lead their attack in some places.
