March of the Twenty-Six 

Between the years 1804 and 1815, Napoleon created twenty-six Marshals of France. These men, who held the highest positions in the Empire after Napoleon himself, came from very diverse backgrounds and ranged from a smuggler to a Prince. They acquired titles and great riches but in the end there was only one who was not corrupted by greed or ambition. This book describes their rise and fall.
