Dear Brad,
I notice you didn't mention good wood, market garden or the bulge. But focusing on the Falais Gap and the similar circumstance towards the end of the bulge, Bedell Smith (Ike's Chief of Staff, if my memory serves) may be correct in putting the credit on the German's will to survive rather than the blame on Monty's failure, but I don't recall any all out effort to close the gap on the part of the Brits or Canadians (no offense to fighting men from either nationality, merely a reflection on the will of their commander), and, if I remember correctly, a Polish force was able to break through the Germans and link up with the Americans, but Monty's forces failed to keep contact with them. Similarly, during the end game of the Battle of the Bulge, while American forces on the Southern Shoulder of the bulge were fighting like heck to pinch off the bulge, Monty's forces on the north of the bulge sat on their butts and failed to link up, again allowing a substantial German force to escape. While eliminating either of these forces would not be certain to end the war, imagine if the British had failed to escape at Dunkirk and lost those 350,000 men. What do you think would have happened? Might that not have knocked them out of the war? I think that perhaps the best indictment of Monty is this: he constantly got his way (except at the very end of the war when Ike wouldn't let him drive for Berlin), was given, due to the support of Churchill, far more resources than any of the American commanders, and yet never won a great victory after El Alamein. And lets face it, at El Alamein he had Ultra codebreakers feeding him Rommels every move, had total air supremecy, ultimate superiority in supplies, shorter supply lines, outnumered the Afrika Corps in Tanks about 600 to 150, his 600 tanks were brand new American Stuarts, M3 Lees and M4 Shermans, while Rommel had 8 Panzer IV specials, 6 Long Barreled Panzer III's, another 15 German tanks, with the remainder being totally inferior Italian M13's. A first year cadet at West Point could have defeated Rommel under these facts. Oh, and the entire plan for the Battle of El Alamein was set up by the outgoing commander (I think it was Percival Waivel, but it might have been Alexander), who was replaced by Churchill because he wanted more time to set up before attacking. Monty merely took the existing plan, waited for the reinforcements his predecessor was denied the time to obtain, and (as was his modus operandi) basked in the spotlight after the totally overmatched German and Italian Forces were inevitably defeated. It was the credit from this lone success that made his entire reputation. I don't think he was half the commander that Slim, of the 14th (forgotten) Army in Burma, was, but the Brits were so desperate for a hero that Monty became untouchable. There is book written by Monty's chief of Staff (a British Officer with a French sounding name) that, if you read between the lines, really rips Monty. If I can find my copy I will loan it to you.
