Great stuff, Bratwurst - rather than drone on for pages, I'll make just two recommendations ; -
First, browse through : -
http://bulge.free.fr/
And then
BUY a copy of William C C Cavanagh's
'A Tour Of The Bulge Battlefield' ( ISBN 0 85052 834 - 8 ), still available from Amazon UK for about ten pounds.
This book isn't perfect, but it's inexpensive, authoritative and will help you get much more from your trip. It will also take you straight to the original foxholes occupied by 2nd Battalion, 56th PIR - the 'Band Of Brothers'.
