I dont know that Monty "pined" anything down, The Germans chose to engadge the enemy on Montys sector, perhaps with the idead that their forces could swing north if Patton did land around Calis. Had they moved south to fight the Americans Monty would have been able to advance faster no doubt. The whole set of events shows that the German Army was beaten.
