Market-Garden was a case in point of the folly of such an attack. It got bogged down in German counterattacks along the supply route, and the entire force was too weak to prevent a German counterattack from cutting off and annihilating major units.
Montgomery was certainly the wrong general to command at Market Garden. While he was a genius at the set-piece battle, dynamic operations were not his strong suit. (The opposite was true with Patton.)
If Patton had run Market Garden, the outcome would likely not have been the disaster that it was.
