If I had not in the wars of the Empire the patriotic spirit of a great national struggle to sustain me, I had a field far wider and grander than any afforded by our Peninsular campaigns; while in the character of the French army, composed as it was of elements derived from every rank and condition, there were picturesque effects one might have sought for in vain throughout the rest of Europe. It was my fortune to have known personally some of those who filled great parts in this glorious drama. I had listened over and over to their descriptions of scenes, to which their look, and voice, and manner imparted a thrilling intensity of interest. I had opportunities of questioning them for explanations, of asking for solutions of this and that difficulty which had puzzled me, till I grew so familiar with the great names of the time, the events, and even the localities, that when I addressed myself to my tale, it was with a mind filled by my topics to the utter exclusion of all other subjects. Neither before nor since have I ever enjoyed to the same extent the sense of being so entirely engrossed by a single theme. A great tableau of the Empire, from its gorgeous celebrations in Paris to its numerous achievements on the field of battle, was ever outspread before me, and I sat down rather to record than to invent the scenes of my story. A feeling that, as I treated of real events I was bound to maintain a degree of accuracy in relation to them, even in fiction, made me endeavor to possess myself of a correct knowledge of localities, and, so far as I was able, with a due estimate of those whose characters I discussed. Some of the battlefields I have gone over; of others, I have learned the particulars from witnesses of the great struggles that have made them famous. To the claim of this exactness I have, therefore, the pretension of at least the desire to be faithful. For my story, it has all the faults and shortcomings which beset everything I have ever written; for these I can but offer regrets, only the more poignant that I feel how justly they are due. The same accuracy which I claim for scenes and situations, I should like, if I dared, to claim for the individuals who figure in this tale; but I cannot, in any fairness, pretend to more than an attempt to paint resemblances of those whom I have myself admired in the description of others. Pioche and Minette are of this number. So is, but of a very different school, the character of Duchesne; for which, however, I had what almost amounted to an original. As to the episodes of this story, one or two were communicated as facts; the others are mere invention. I do not remember any particulars to which I should further advert; while I feel, that the longer I dwell upon the theme, the more occasion is there to entreat indulgence,--an indulgence which, if you are not weary of according, will be most gratefully accepted by Your faithful servant, CHARLES LEVER Casa Capponi, Florence, May, 1867.
