Of course, it was Monty's fault that the Scheldt estuary situation occurred at all. He had halted to tidy things up after the Germans had retreated into Holland. Market-Garden was approved by Eisenhower mostly in his belief that Monty would clean up the Scheldt estuary problem and enable Antwerp to function as a port. Had that nutty PLUTO bright idea actually worked, fuel could have been delivered to the Continent without any need for a port. I find it difficult to understand the consistent lack of knowledge exhibited in the planning of Overlord. I've come to believe it was the most poorly planned Allied operation of the war.
