Sounds interesting. Hope it comes out in an ebook form.
Don't much care for books on N. but books on the people close to him are interesting.
what interests me a bit is his death.
Found this on Bertier's death which seems to add some detail. In German but well written and translates well.
My interest stems from the point that death at the hands of the local Russian's passing through is the most obvious answer. B. had dinner with some Russian officers and they commented on his loyalty to the King and if B. gave anything less than a perfect answer, the Russians likely would consider it their duty to eliminate one of N.'s most valued officers; according to some, the most important officer that N. was missing.
Presumably, since it would not be honorable to shoot somebody not in uniform, and not wanting to advertise what they had done, the best answer would be arranging a trip out the window.
1815 was no ordinary marching off to war for the Russians and Prussians, the regular soldier was filled with a lot of anger at having to again deal with N. Letting the "prince of Wagram" live after it was known that he was anxiously trying to get back to France would be impossible. If B. was still loyal to the King, why would he be trying to return to France where the King wasn't? The only reasonable conclusion that could be made -by the Russians on the spot- was that he was going back to join N.
