At a time when military commanders in Europe were royal princes and dukes, Napoleon's marshals were often the sons of peasants or clerks. And they were usually half the age of their opponents - whom they thrashed soundly with almost monotonous regularity. This is the story of Ney, Murat, Soult, Davout, Bernadotte, Massena, Lannes, Marmont and Augereau. It took, for instance, only 23 days for the entire Prussian army to be defeated and one of the French marshals, Augereau, had the pleasure of taking prisoner the feared Prussian Guards, a regiment he had deserted 20 years earlier in order to become a dancing master. A.G. Macdonell is also the author of England, their England.
