Craig, read The Desert Fox if you get a chance. Rommel was a soldier's soldier, beloved by all his men. Hitler rode on his coat tails as long as retreat was not an option, but Rommel knew that to retreat strategically was to be able to fight another day. Hitler probably couldn't share the limelight or the public's admiration of this 5' 2" master-of-the-infantry.
He set up Normandy defenses and his actions would have resulted in far more allied lives if he hadn't voluntarily taken poison rather than die dishonorably. I think Rommel's suicide turned the heads of many generals, some of whom tried to assassinate Hitler rather than have him sacrifice all, foolishly. (Can you imagine the feeling of realizing you followed a maniac and killed for him and that your country's near-future was looking mighty dark?)
According to the American version of Montgomery, Monty was too timid, hated to lose, strategically rigid and a publicity hound (like Patton and Mac Arthur, both of who had far more talent). According to The Desert Fox, Monty had many opportunities to destroy Rommel in N. Africa, but Rommel's genius of using nature's forces, 88's, land mines, surprise and troop movements to deceive reconnaisance, kept Monty at bay. Monty was only able to nip at Rommel's heels back across Africa, even though Rommels's forces were deprived of critical supplies, especially gas.
John Toland's books about WW2 are fascinating, though they give a somewhat contemporary veiw of a few things that I disagree with, like the dropping of the bomb. The Rise and Fall of the Third Reich and The Rising Sun, are just two of his that I read twice.
Makes you think of the mistakes that cost the lives of thousands, made by a certain few generals on both sides, and that sometimes ignorance is bliss when following orders. Chaos is fine when you're on a rollercoaster, but finding out the rollercoaster left the tracks a minute ago, must feel like free falling in a different dimension. I guess that's war. Somehow men like Rommel could work within chaos and come out without a scratch.
As far as I know, he never joined the Nazi party.
