Our domestic contest, now happily ended, has left some traces in our relations with one at least of the great maritime powers. The formal accordance of belligerent rights to the insurgent States was unprecedented, and has not been justified by the issue. But in the systems of neutrality pursued by the powers which made that concession there was a marked difference. The materials of war for the insurgent States were furnished, in a great measure, from the workshops of Great Britain, and British ships, manned by British subjects and prepared for receiving British armaments, sallied from the ports of Great Britain to make war on American commerce under the shelter of a commission from the insurgent States. These ships, having once escaped from British ports, ever afterwards entered them in every part of the world to refit, and so to renew their depredations. The consequences of this conduct were most disastrous to the States then in rebellion, increasing their desolation and misery by the prolongation of our civil contest. It had, moreover, the effect, to a great extent, to drive the American flag from the sea, and to transfer much of our shipping and our commerce to the very power whose subjects had created the necessity for such a change. These events took place before I was called to the administration of the Government. The sincere desire for peace by which I am animated led me to approve the proposal, already made, to submit the question which had thus arisen between the countries to arbitration. These questions are of such moment that they must have commanded the attention of the great powers, and are so interwoven with the peace and interests of every one of them as to have insured an impartial decision. I regret to inform you that Great Britain declined the arbitrament, but, on the other hand, invited us to the formation of a joint commission to settle mutual claims between the two countries, from which those for the depredations before mentioned should be excluded. The proposition, in that very unsatisfactory form, has been declined.
The United States did not present the subject as an impeachment of the good faith of a power which was professing the most friendly dispositions, but as involving questions of public law of which the settlement is essential to the peace of nations; and though pecuniary reparation to their injured citizens would have followed incidentally on a decision against Great Britain, such compensation was not their primary object. They had a higher motive, and it was in the interests of peace and justice to establish important principles of international law. The correspondence will be placed before you. The ground on which the British minister rests his justification is, substantially, that the municipal law of a nation and the domestic interpretations of that law are the measure of its duty as a neutral, and I feel bound to declare my opinion before you and before the world that that justification can not be sustained before the tribunal of nations. At the same time, I do not advise to any present attempt at redress by acts of legislation. For the future, friendship between the two countries must rest on the basis of mutual justice.
