I think it is relevant that had Market Garden succeeded, Bradley would launch an all-out attack with two Armies (Ninth and First) on the Ruhr, with the 21st Army guarding his left. They would attack through the corridor the Schlieffen plan exploited as its line of march. If the Allies took the Ruhr the German army dies. Market-Garden failed because of both flawed execution and its stint of incredible bad luck. The 82d lost no less than three major river crossings to German demolition teams by seconds. To change the outcome of the battle without rewriting the plan, I pin the blame on XXX Corps. Horrocks latter would admit that had the importance of securing attacking positions for Market-Garden been made clear to him, he would have drove the XXX Corps much harder before the operation. Another flaw was the XXX Corps' lack of immediate engineer support when they most needed it. Engineers should have been placed at the point of the XXX Corps's advance, not behind.
