Wow... no wonder we won the war, with those kind of odds. A division (10k -15k troops) attaking a squad (9-10 troops). I think those comabt ratios would have made short work of the enemy, or an extreme tie up of manpower......

With the anniversary of D-Day still fresh there are a slew of book availiable for reference right now that give all kinds of great info. Orders of Battle, etc. that are priceless bits of info and will show you who fought who and what groups were brought into play.
Here's a couple of links that should help.

Good luck and be sure to keep us updated. Sounds like quite the diorama.
