This author is fantastic! He specializes in the history of Napoleon. This is not his first book he also tell many episodes in the life of this great historical figure. He even wrote Napoleon explained to the children. This is probably what explains that it manages to make us pass her love for Napoleon and the history through a well-researched book, based on archives and fictionalized just enough to interest the general public. It is beautifully written. The only thing I regret is the price of the book since its thickness. But it justifiable price for the quality of the writing. Boudon tells us here a very important episode in the life of Napoleon, but if you want to know the result look towards the author recounts many episodes of Napoleon's conquests in other work.
