An apology seems to be called for from anyone who gives to the world a new Life of Napoleon I. My excuse must be that for many years I have sought to revise the traditional story of his career in the light of facts gleaned from the British Archives and of the many valuable materials that have recently been published by continental historians. To explain my manner of dealing with these sources would require an elaborate critical Introduction; but, as the limits of my space absolutely preclude any such attempt, I can only briefly refer to the most important topics.
