The work is a model of patient study, not alone of what is conventionally accepted as historic material, but of all subsidiary matter necessary to expert discussion of the problems involved. He goes deeply into economic and social facts; he has instructed himself in military science like a West Point student, in army needs like a quartermaster, in naval construction, equipment, and management like a naval officer. Of purely literary qualities, the history presents a high order of constructive art in amassing minute details without obscuring the main outlines; luminous statement; and the results of a very powerful memory, which enables him to keep before his vision every incident of the long chronicle with its involved groupings, so that an armory of instructive comparisons, as well as of polemic missiles, is constantly ready to his hand. He follows the latest historical canons as to giving authorities. The history advances many novel views, and controverts many accepted facts. The relation of Napoleon's warfare against Hayti and Toussaint to the great Continental struggle, and the position he assigns it as the turning point of that greater contest, is perhaps the most important of these. But almost as striking are his views on the impressment problem and the provocations to the War of 1812; wherein he leads to the most unexpected deduction,--namely, that the grievances on _both_ sides were much greater than is generally supposed. He shows that the profit and security of the American merchant service drew thousands of English seamen into it, where they changed their names and passed for American citizens, greatly embarrassing English naval operations. On the other hand, he shows that English outrages and insults were so gross that no nation with spirit enough to be entitled to separate existence ought to have endured them. He reverses the severe popular judgment on Madison for consenting to the war--on the assumed ground of coveting another term as President--which every other historian and biographer from Hildreth to Sydney Howard Gay has pronounced, and which has become a stock historical convention; holds Jackson's campaign ending at New Orleans an imbecile undertaking redeemed only by an act of instinctive pugnacity at the end; gives Scott and Jacob Brown the honor they have never before received in fair measure; and in many other points redistributes praise and blame with entire independence, and with curious effect on many popular ideas. His views on the Hartford Convention of 1814 are part of the Federalist controversy already referred to.
