A masterful plan, an appreciation of terrain, superb timing, a steady nerve, the discipline and training instilled at Boulogne, the corps system, exploitation of a momentary numerical advantage at the decisive point, tremendous esprit de corps, fine performances on the day by Friant, Davout, Vandamme, Soult and Saint-Hilaire, and a divided and occasionally incompetent enemy – Büxhowden was drunk during the battle – had given Napoleon the greatest victory of his career.
