Combat,
This is going to sound strange coming from a guy who is on the record as believeing that most 20th Century Generals were incompetents, but I have to respectfully disagree with your assessment of Rommel in North Africa. The man was always under supplied, led mostly extremely poorly armed and equipped Italian troops against the cream of British and Commonwealth troops, was drastically outnumbered in quantity and quality of tanks (he had only a couple of dozen Panzer III and Panzer IV specials with long barreled high velocity guns, and the remainder of his tanks were a few short barreled Panzers and junky Italian M13 tanks and Semovente self propelled guns)always faced both Allied Air dominance and, later due to the code breakers at Blenchly Park, had all his plans revealed to his opposition, and still came within a whiskers breath of total victory in North Africa (if the ANZAC forces don't hold out a Tobruk, Rommel has his dinner in Cairo). If anybody was overrated in North Africa, it was that bumbler Montgomery, who made his name by triumphing under the above described circumstances. Lets face it, you give a first year cadet at any military school the advantages Monty had over Rommel (including 500 brand new M3 Lee and M4 Sherman tanks going up against less than 125 German and Italian tanks, 100 of which were Italian) and the first year student is going to win.
