Taking into account that the book was written in the 1960ies and the author was trapped in the Stalingrad pocket and then was gulaged for a decade, the work is biased and looking for who is to blame for the demise of the Sixth Army. The memoirs can be seen at some level like a self-pity for the men fighting for Hitler, but the author is aware of that as he starts thinking of the bad treatment of the defeated Russians earlier in the war, now that his army is at the losing side.
The book analysis Manstein, Paulus and Seydlitz in the second half, where the first is blamed for not taking his part of the responsibility, the second is seen as servile and apathetic to Hitler’s wishes and the last (who surrendered without being allowed to do so) has a fair grasp of the dire situation, but is not allowed to break out out early on (which might have saved the army).
