The military incidents at which we are now to glance form one of the most dramatic chapters in the military history of modern Europe. We must go to the career of Alexander the Great or of Hannibal for wars so full of personal, military, and national interest as those which saw the fall and the overthrow of Napoleon. But in accordance with the general purposes of this book the story of the fighting will be very lightly passed over. Our chief effort will be to gain some idea of the forces which were making for the overthrow of the great conqueror.
