But I should not have ventured on this great undertaking, had I not
been able to contribute something new to Napoleonic literature. During
a study of this period for an earlier work published in the "Cambridge
Historical Series," I ascertained the great value of the British
records for the years 1795-1815. It is surely discreditable to our
historical research that, apart from the fruitful labours of the Navy
Records Society, of Messrs. Oscar Browning and Hereford George, and of
Mr. Bowman of Toronto, scarcely any English work has appeared that is
based on the official records of this period. Yet they are of great
interest and value. Our diplomatic agents then had the knack of
getting at State secrets in most foreign capitals, even when we were
at war with their Governments; and our War Office and Admiralty
Records have also yielded me some interesting "finds." M. Lévy, in the
preface to his "Napoléon intime" (1893), has well remarked that "the
documentary history of the wars of the Empire has not yet been
written. To write it accurately, it will be more important thoroughly
to know foreign archives than those of France." Those of Russia,
Austria, and Prussia have now for the most part been examined; and I
think that I may claim to have searched all the important parts of our
Foreign Office Archives for the years in question, as well as for part
of the St. Helena period. I have striven to embody the results of this
search in the present volumes as far as was compatible with limits of
space and with the narrative form at which, in my judgment, history
ought always to aim.

On the whole, British policy comes out the better the more fully it is
known. Though often feeble and vacillating, it finally attained to
firmness and dignity; and Ministers closed the cycle of war with acts
of magnanimity towards the French people which are studiously ignored
by those who bid us shed tears over the martyrdom of St. Helena.
