First the mistakes. Has Peiper as an Obersturmführer (1st Lt) at the battle of the Bulge, he was an Obersturmbannführer (Lt Col). Skips Obersturmbannführer in the SS ranks in the back and has Standartenführer as Lt Col when it was full Colonel. Shows Oberführer as Brigadier when it was senior Colonel.
There is nothing much of substance about Sepp, even telling about one of his interviews with Sepp's son Wolf-Dieter would have been a huge improvement. You learn of Sepp vicariously through his times. As I said all the direct information about Sepp in the book would have taken up one chapter, all the rest was filler that I had read about before in other books. Messenger did an outstanding job with what he had to work with, even though I have read many books about Sepp I still learned.
To sum it up, I liked the book because it was better than nothing but gives little direct information about Sepp. Too bad he could not have at least contacted people who knew Sepp after the war. I am happy I read the book, thanks to the other reviews I did not expect much and was not dissapointed. Even the photos were lacking, a nice color photo would have been nice.
There are two biographies about Sepp Dietrich: one by Charles Messenger of which there are two versions, this one was written in 1988, the other was written in 2005. The other biography by Jean Mabire is in French, so as you can see information about Sepp has to be gleaned from other books.

Any correction to my review are most welcome, if you have read the later Messenger book please let me know if there is any updated information.
