Hello Jeff, The only words from Monty on the subject that I have seen are in his memoirs, 'The Memoirs of Field-Marshal Montgomery' (Pen & Sword - Military), page 274, last paragraph. "On the 9th September I received information from London that on the previous day the first V2 rockets had landed in England; it was suspected that they came from areas near Rotterdam and Amsterdam and I was asked when I could rope off those general areas. So far as I was concerned that settled the direction of the thrust line of my operations to secure crossings over the Meuse and Rhine; it must be towards Arnhem..." There is more background in his memoirs... I trust that this is helpful. Best, Steve. There were a couple of other important factors - the hope that a thrust in the direction of Arnhem would isolate the 15th Army or draw forces away from offensives aimed at Holland. The consideration of the problems of famine in the Netherlands over the winter of 44/45 and the need to releive it quickly was another factor.
