Let us do him justice. Prejudiced and ignorant and wrong-headed as he was, he was a pure patriot, laboring for his country's good. Nothing proves this more strongly than his attitude on the nullification question, in other words, the right of a state to refuse to obey a law of the United States, and to withdraw from the Union, should it so desire. This is not the place to go into the constitutional argument on this question. It is, of course, all but certain that the original thirteen states had no idea, when they ratified the Constitution, that they were entering an alliance from which they would forever be powerless to withdraw; and the right of withdrawal had been asserted in New England more than once. South Carolina was the hot-bed of nullification sentiment, arising partly from the growing anti-slavery feeling at the North, and partly because of the enactment of a tariff law which was felt to be unjust, and on October 25, 1832, the South Carolina legislature passed an ordinance asserting that, since the state had entered the Union of its free will, it could withdraw from it at any time and resume the sovereign and independent position which it had held at the close of the Revolution, and that it would do so should there be any attempt to enforce the tariff laws within the state. Jackson's attitude on this question was already well known. At a banquet celebrating Jefferson's birthday, two years before, at which Calhoun and others had given toasts and made addresses in favor of nullification, Jackson had startled his audience by rising, glass in hand, and giving the toast, "Our Federal Union--it must be preserved!" That toast had fallen like a bombshell among the ranks of the nullifiers, and had electrified the whole Nation. Since then, he had become a stronger nationalist than ever; besides, he was always ready for a fight, and whenever he saw a head had the true Irishman's impulse to hit it. So he responded to the South Carolina nullification ordinance by sending two men-of-war to Charleston harbor and collecting a force of United States troops along the Carolina border. "I consider the power to annul a law of the United States, assumed by one state, incompatible with the existence of the Union," he wrote; and when a South Carolina congressman, about to go home, asked the President if he had any commands for his friends in that state, Jackson retorted: "Yes, I have; please give my compliments to my friends in your state, and say to them that if a single drop of blood shall be shed there in opposition to the laws of the United States, I will hang the first man I can lay my hands on, engaged in such treasonable conduct, upon the first tree I can reach."
