But the victorious general was still the same Andrew Jackson; he did not leave New Orleans without exhibiting some of the characteristics that were so well known in Tennessee. Relaxing none of his vigilance, he kept the city under martial law after the British had sailed, and even after the British admiral had sent him word of the peace. Many New Orleans people protested, and certain of them claimed exemption from the work of defense on the ground that they were citizens of France. All such he ordered out of the city. Mr. Louaillier, a leading citizen, published a protest, and Jackson promptly arrested him. Judge Hall, of the United States District Court, issued a writ of habeas corpus for the prisoner, and Jackson as promptly arrested the judge himself, and did not release him until, early in March, official notice of the peace was received. The judge fined the general a thousand dollars for contempt of court, and nearly thirty years afterwards the American Congress voted money enough to repay the sum with interest. Between the battle and the news of peace, Jackson also signed the order for the execution of six militiamen whom a court-martial had found guilty of mutiny and desertion. There were circumstances which seemed to recommend these men to mercy, and in after years the order was cited along with other things to prove that Jackson was a cruel and arbitrary commander.
However, the War Department gave him only the mildest of reproofs for his treatment of the civil authorities at New Orleans, and when he returned to Tennessee it was to a welcome even more heartfelt and stirring than the one he got on his return from the Creek war. In the autumn he was called to Washington to consult with his superiors about putting the army on a peace footing, and on the journey and at the capital he was universally received as the hero of the war. The army was reduced to ten thousand men, and distributed into a northern and a southern department. The command of the northern department was given to General Jacob Brown; Jackson got the southern department.
It was about this time that Governor Alston, of South Carolina, got a letter from his father-in-law, Aaron Burr, of New York, concerning the approaching presidential election. Burr thought Monroe, the leading candidate and the man preferred by President Madison, too weak a man for the great office. He wanted a man of firmness and decision, and he added, "that man is Andrew Jackson." But as yet Jackson himself had no such ambition. As late as 1821, in fact, he said, in reply to a suggestion that he might be President: "No, sir; I know what I am fit for. I can command a body of men in a rough way; but I am not fit to be President." He cordially supported Monroe in 1816, and after his election wrote to him and made a few suggestions about his administration. One of these suggestions was to appoint a Federalist, Colonel William Drayton, Secretary of War. Jackson declared that, had he been in command in New England, he would have hanged the leaders of the Hartford Convention; but he was in favor of recognizing the loyalty of such Federalists as had served the country faithfully during the war. That letter to Monroe was "copied" for the general by his neighbor and friend, William B. Lewis, as were hundreds of others. The general himself was a poor writer, and Major Lewis was a skilful man with a pen. He was also an exceedingly clever politician, and he showed his cleverness by keeping a second copy of the letter to Monroe for future use. In the course of the correspondence, Monroe let Jackson know that he himself might be Secretary of War if he chose; but Jackson was content with his command.
