As Führer of the Third Reich, Hitler was responsible for deciding the German war aims in 1939. As head of the Armed Forces from 4 February 1938 he was also responsible for the overall Wehrmacht strategy intended to achieve these aims.

Hitler: Military Commander examines Hitler's key military decisions during the Second World War, and assesses how far these decisions were militarily justified in light of the intelligence available at the time.

Perhaps most importantly it tackles the larger questions of how a non-German former corporal, albeit the holder of the Iron Cross 1st Class, managed to take personal control of an army with the Prussian traditions of the German Army, appoint, sack and sentence to death its generals at will, to lead it into a World War it was not prepared for, and, ultimately, to destroy it.
