Sir, we were at war with the greatest maritime power on earth. England had gained an ascendency on the seas over all the combined powers of Europe. She had been at war twenty years. She had tried her fortunes on the Continent, but generally with no success. At one time the whole Continent had been closed against her. A long line of armed exterior, an unbroken hostile array, frowned upon her from the Gulf of Archangel, round the promontory of Spain and Portugal, to the extreme point of Italy. There was not a port which an English ship could enter. Everywhere on the land the genius of her great enemy had triumphed. He had defeated armies, crushed coalitions, and overturned thrones; but, like the fabled giant, he was unconquerable only while he touched the land. On the ocean he was powerless. That field of fame was his adversary's, and her meteor flag was streaming in triumph over its whole extent.

To her maritime ascendency England owed every thing, and we were now at war with her. One of the most charming of her poets had said of her,—

"Her march is o'er the mountain waves,
Her home is on the deep."

Now, Sir, since we were at war with her, I was for intercepting this march; I was for calling upon her, and paying our respects to her, at home; I was for giving her to know that we, too, had a right of way over the seas, and that our marine officers and our sailors were not entire strangers on the bosom of the deep. I was for doing something more with our navy than keeping it on our own shores, for the protection of our coasts and harbors; I was for giving play to its gallant and burning spirit; for allowing it to go forth upon the seas, and to encounter, on an open and an equal field, whatever the proudest or the bravest of the enemy could bring against it. I knew the character of its officers and the spirit of its seamen; and I knew that, in their hands, though the flag of the country might go down to the bottom, yet, while defended by them, that it could never be dishonored or disgraced.

Since she was our enemy, and a most powerful enemy, I was for touching her, if we could, in the very apple of her eye; for reaching the highest feather in her cap; for clutching at the very brightest jewel in her crown. There seemed to me to be a peculiar propriety in all this, as the war was undertaken for the redress of maritime injuries alone. It was a war declared for free trade and sailors' rights. The ocean, therefore, was the proper theatre for deciding this controversy with our enemy, and on that theatre it was my ardent wish that our own power should be concentrated to the utmost.

So much, Sir, for the war, and for my conduct and opinions as connected with it. And, as I do not mean to recur to this subject often, nor ever, unless indispensably necessary, I repeat the demand for any charge, any accusation, any allegation whatever, that throws me behind the honorable gentleman, or behind any other man, in honor, in fidelity, in devoted love to that country in which I was born, which has honored me, and which I serve. I, who seldom deal in defiance, now, here, in my place, boldly defy the honorable member to put his insinuation in the form of a charge, and to support that charge by any proof whatever.

The gentleman has adverted to the subject of slavery. On this subject, he says, I have not proved myself a friend to the South. Why, Sir, the only proof is, that I did not vote for his resolutions.

Sir, this is a very grave matter; it is a subject very exciting and inflammable. I take, of course, all the responsibility belonging to my opinions; but I desire these opinions to be understood, and fairly stated. If I am to be regarded as an enemy to the South, because I could not support the gentleman's resolutions, be it so. I cannot purchase favor from any quarter, by the sacrifice of clear and conscientious convictions. The principal resolution declared that Congress had plighted its faith not to interfere either with slavery or the slave trade in the District of Columbia.

Now, Sir, this is quite a new idea. I never heard it advanced until this session. I have heard gentlemen contend that no such power was in the Constitution; but the notion, that, though the Constitution contained the power, yet Congress had plighted its faith not to exercise such a power, is an entire novelty, so far as I know. I must say, Sir, it appeared to me little else than an attempt to put a prohibition into the Constitution, because there was none there already. For this supposed plighting of the public faith, or the faith of Congress, I saw no ground, either in the history of the government, or in any one fact, or in any argument. I therefore could not vote for the proposition.

Sir, it is now several years since I took care to make my opinion known, that this government has, constitutionally, nothing to do with slavery, as it exists in the States. That opinion is entirely unchanged. I stand steadily by the resolution of the House of Representatives, adopted, after much consideration, at the commencement of the government, which was, that Congress has no authority to interfere in the emancipation of slaves, or in the treatment of them, within any of the States; it remaining with the several States alone to provide any regulations therein, which humanity and true policy may require. This, in my opinion, is the Constitution and the law. I feel bound by it. I have quoted the resolution often. It expresses the judgment of men of all parts of the country, deliberately and coolly formed; and it expresses my judgment, and I shall adhere to it. But this has nothing to do with the other constitutional question; that is to say, the mere constitutional question whether Congress has the power to regulate slavery and the slave trade in the District of Columbia.
