Chandler’s Campaigns of Napoleon is an incredible book. If you haven’t read it, I would very much recommend it. The one problem Napoleon had was that he either couldn’t or wouldn’t teach to others what he was able to do himself. The Germans learnt this lesson and the result was the German General Staff which Scharnhorst (Blucher’s chief of staff) recreated based on the lessons learned from Napoleon. The principal goal of the German General Staff was to identify and then train officers who would excel at fighting on an operational level.
