I prefer reading first person accounts before "historians" can give us an official history.
I have enjoyed reading the German generals autobiography's because some of them enjoy snipping at each other after the fact. Guderian was much nicer to Manstein, than he was to him... Manstein was a military genius who I'm pretty sure would have won the war with Kesselring if Hitler went on vacation. Rommel was a good field commander but was to moody and worried about other things to be a proper theater commander.
Others are just interesting like Hans von Luck.
You also get to find out interesting little facts like how Luck was the go between for Rommel and Guderian and set up a quite little meeting so Rommel could try to recruit him for the July 20th plot.
I know how they viewed Hitler and his inner circle, now I'm very interested in what the inner circle thought of them.
