Thanks for the kind words. I may revive the map posts for Market-Garden and Scheldt Estuary. Probably Metz, too. Definitely Ardennes Offensive.
One of the many stories I have read about Patton is that his most used map was a Michelin road map of the region. That would reveal N.E. France as flat as a billiard table and served by an extensive road net - ideal tank country. There really is no natural defensive line for the Germans until they retreat to the German border and Dutch rivers.
