I'm with syscom and Njaco on this one. By September, the Allies were running low on supplies. There was just enough supplies left for one more major push
at this time. If were thinking of Market-Garden, it did offer a way into the Ruhr Valley in a quick manner-provided that everything went according to plan. We all
know how that ended. Again, the biggest thing that armies like this need are supplies. BT has a quote that I respect, about how great generals think of logistics
instead of tactics. Unless supplies could have been delivered quickly enough to the front in great quantity, the Allies are going nowhere. Even if they took Aachen,
then what? Would have even have enough gas, ammo, etc. to exploit that? Probably not. In regards to Ike's Broad Front strategy, I think the rationale behind was
that one major push could end up being surrounded by the Germans. With the Broad Front idea, the German's would have to defend several points of attack at
once, using up their manpower and resources. Anyway, I'm starting to ramble.
