"A Time For Trumpets" is an excellent choice for reference. My boss was one of the people who provided the German order of battle for the book as noted in the appendix. Another good book is George Koskimaki's book, "The Battered B------'s of Bastogne", as he was in Bastogne as the NCOIC of the 101st's Signal component.
