Yes indeed. I know you have extensive knowledge of the area and the battle and I hope my words didn't come across harshly for that is not how I meant for it all. You are very knowledgable and that's one of the reasons I enjoy your presence here on our forum. 
Sometimes when I am speaking I am doing so for the benefit of all reading, so thus when I say, "...but the Battle of the Bulge doesn't just mean Bastogne, but refers to entire areas of Alsace and the Ardennes...", it's for everyone who may not know much about BOB.
As far as the campaigns, the two are inter-mixed many times when credits were given to the units. If you look on various documents such as my dad's discharge papers, or read through army archives, it will simply state Ardennes/Alsace Campaign. That's throwing a lot in there hey? Sure is!
