There was a book years ago called, "Ninety Days that doomed the Axis". The ninety days encompassed the Battle of El Alemein in October, 1942, Stalingrad, which fell in Feburary and Guadalcanal, which the Japs began to evacuate, also in February. But Hitler didn't lose that much at El Alemein -- he didn't have much to lose. After the Allies landed in Northwest Africa, Hitler ordered a big reinforcement of North Africa -- even though he hadn't been able to supply the much smaller Afrika Corps. This was more of his intuition. The Axis lost @ 250,000 troops in NA (lots of Italians though). Really, the surrender at Tunis was a big kicker of a defeat. I think that was like April, 1943.

Hitler lost that part of the war at El Alamein, Walt. Numerical losses mean little when the strategic blow is overwhelming.
