[Dénes Bernád]

I cannot think of a sharper turn in topics of interest for a historian, who wrote about the Luftwaffe (author of "Stopped at Stalingrad") than this.
The next book of the aforementioned author is called "The Leadership of Muhammad: A Historical Reconstruction". The first sentence of the abstract is enough for this forum, I think: "Given Prophet Muhammad’s a immense impact on history, there are surprisingly few books that specifically analyse his leadership."
