As the war progressed Hitler did not need obedient bureaucrats like Keitel, failures like Paulus and was paranoid about having military leaders who were loyal. The three field marshals in this book were amongst the best.

Field Marshal Kesselring gained a reputation in Italy as an expert in defense, and his Allied code name was The Emperor. Kesselring was diplomatic, charming, known as Smiling Albert, but convicted as a war criminal which may not have happened had it not been for the bitter partisan war. 

Field Marshal Rommel is surrounded by myths which need disentangling. He possessed exceptional qualities of command and leadership, with personal courage and determination, but had problems caused by two major reasons. The first was his relentless ambition, which prevented him from self-criticism and self-evaluation. The second was his meteoric rise in command, and like many other commanders driven by ambition.

Field Marshal Model when on the battlefield led his men so well it is surprising that little is known of him. He fought defensive battles in a way hardly matched by any other German general. He had the immense capability of keeping his nerve, but his skills as a commander, were not matched by the sort of personality which may have given him a similar status as with Rommel, and not helped by challenging Hitler. Model had a reputation of being so tough even Hitler claimed he would not want to serve under him, he was known as the Frontschwein (front-line pig).
