Ignore your Intelligence showing Panzer Divisions in the area....run your entire attack up a single two lane road across a bunch of bridges (any one of which if lost or destroyed shoots your whole plan in the ass), take three days to get all your forces dropped into the battle area, and you want to drag Patton into it somehow?
There was an Airborne Army sitting around looking for work thus a "plan" was devised to put it to use....in Montgomery's area of operations of course.
Eisenhower should have been a mite less diplomatic I am thinking.
Deal with reality.....Montgomery was a proper Knob on this one and a great many brave Man died because of his gross failure.
