Hello, I am trying to accurately locate all of the units that made up the Special Bridging Force for Operation Market Garden and I need the following units. As I have a military map of the Bourg-Leopold area a simple map reference will do. The units are: 6th Army Troops, RE, 7th Army Troops, RE, the 15th GHQ, 69th, 70th, 71st, 72nd, 73rd, 183rd, 582nd, 583rd and 584th field companies and the 227th, 277th and 297th field park companies. I know that this is a lot, but every bit helps. Thanks, John
