I read Guderian's autobioigraphy and found it very self serving and full of excuses, "We could have won the war if Hitler had listened to me.".
B. Lidell Hart connived with Guderian to get both of them luster.
I think one has to read multiple "versions" about something like this to start to get a truer picture.
We Americans and Brits have heard of Rommel of course, but no Balck and Manstein and Guderian and Kesselring nearly to the same extent. Manstein may have been the best general in the 20th century both in tactical and strategic terms. Rommel was built up by Hollywood and the Brits because Monty "beat him".
Rommel was a fine general I think, very daring, had he been given more support in North Africa, the Germans might have taken the mideast oil fields and Suez.
