It was late in the year 1817 before General Jackson was again called to active service in the field. Once more the call was from the southward, and his old enemies, the Red Sticks, the English, and the Spaniards, were all in some measure responsible for it. A number of Red Sticks had taken refuge with their kinsmen, the Seminoles, in Florida. Colonel Nichols and a small force of British had also remained in Florida some time after the war ended, and had done things of a nature to stir up the Indians there against the Americans across the border. Negro slaves, escaping from American masters, had fled to the Spanish province in considerable numbers, and a body of them got possession of a fort on the Apalachicola River which had been abandoned by the British. To add to the disorder of the province, it was frequented by adventurers, some of them claiming to be there in order to lead a revolution against Spain, some of them probably mere freebooters. The Spanish authorities at Pensacola were too weak to control such a population, and Americans near the border were anxious to have their government interfere. The negro fort was a centre of lawlessness, and some American troops marched down the river, bombarded it, and by a lucky shot blew up its magazine and killed nearly three hundred negroes. Troubles arose with the Indians also, and Fowltown, an Indian village, was taken and burned. A considerable body of Indians took to the war-path, and Jackson was ordered to the scene.

Impatient as ever with the Spaniards, he wrote to President Monroe: "Let it be signified to me through any channel (say Mr. J. Rhea) that the possession of Florida would be desirable to the United States, and in sixty days it will be accomplished." Monroe was ill at the time, and for some reason did not attend to the general's letter for a year. The President was trying to get Florida peaceably, by purchase, and not by conquest. Jackson, however, got the idea that his suggestion was approved, and acted accordingly.

Raising troops in Tennessee on his own authority, he marched rapidly to the scene of trouble, crossed the border into Florida, and in a few weeks crushed the Seminoles. Of fighting, in fact, there was very little; what there was fell almost entirely to the friendly Indians, and not a single American soldier was killed. But Jackson's actions in the campaign brought on the bitterest controversies of his career. By his order four men were put to death, and he captured Pensacola again, claiming that some Indians had taken refuge there. Two of the four men were Creek Red Sticks. The other two were white men and British subjects. One was Alexander Arbuthnot, an old man of seventy, a trader among the Indians, and, so far as is known, a man of good character. He was taken prisoner, however, and it is supposed a letter he wrote to his son, telling him to take their merchandise to a place of safety, warned some Indians of Jackson's approach. The other British subject was an Englishman named Robert Ambrister, who had been a lieutenant in the British army. He was nephew to the governor of New Providence, one of the British West Indies, and seems to have been in Florida rather in search of adventure than for any clearly ascertainable purpose. A court-martial found Arbuthnot guilty of inciting the Creek Indians to rise against the United States, and of aiding the enemy. Ambrister was found guilty of levying war against the United States. He was first sentenced to be shot; then, on reconsideration, the court changed the sentence to fifty stripes and hard labor for a year. Jackson firmly believed that both were British emissaries, sent to Florida to stir up the Indians. He disapproved the change of Ambrister's sentence, and ordered him to be shot and Arbuthnot to be hanged.

Such fierce and energetic measures, whether justifiable or not, put an end to the disorder on the border, and Jackson was again free to return home a victor. The country was disposed to approve what he had done, but the President and Cabinet saw that grave international questions would be raised; for Jackson had invaded the soil of a country at peace with the United States, taken possession of its forts, and put to death citizens of another country also at peace with the United States. John C. Calhoun, of South Carolina, the Secretary of War, was in favor of censuring the general for his conduct; but John Quincy Adams, of Massachusetts, the Secretary of State, thought his acts necessary under the circumstances, and declared himself ready to defend them. In the end he did defend them so well that neither Spain nor Great Britain made serious trouble over them. The President and his Cabinet followed Adams's advice instead of Calhoun's, and Calhoun himself, as Jackson's superior, wrote to him about the campaign in a friendly way. Jackson naturally thought that Calhoun had been his friend in the Cabinet, and had no reason to suspect that it was Adams who defended, and Calhoun who wished to censure him. He did not learn the truth for many years. Had he known it sooner, there is no telling how different the political history of the next twenty years might have been.

For henceforth Jackson was to be a great figure not in warfare but in politics. His military career was practically ended. He kept his commission until July, 1821, but from this time he fought no more battles. He had not, as a soldier, given such evidence of military genius as to set his name alongside those of the great captains of history, but he had shown himself a strong and successful leader of men; in his masterful, often irregular and violent way, he had done his country good service. Were his place in history merely a soldier's, it would be a safe one, though not the highest. But his actions in the field soon gave him the leading part on a different stage. One day in January, 1819, he rode up to the house of his neighbor, Major Lewis, who had just bought a new overcoat, and asked him to get himself another; the general wanted the one already made to wear on a long journey. "Major," he said, "there is a combination in Washington to ruin me. I start to Washington tomorrow."

The chief of those who, as Jackson firmly believed, were combined to ruin him, was the man who could with best reason be compared to the hero of New Orleans for the place he had in the affections of the Western people and as the representative of the new American spirit, born of the second war with Great Britain. If Jackson was the hero of the war, Henry Clay was its orator; if it was Jackson who sent from one quarter the news of a glorious victory, it was Clay who, with Adams and Gallatin, had secured the peace. Leaving Ghent, Clay was lingering in Paris when he heard the news of New Orleans. "Now," he exclaimed, "I can go to England without mortification." But the great orator was not in sympathy with Monroe's administration. His enemies declared he was in opposition because he was not asked to be Secretary of State, and because he feared that Adams, who had the place, would become President four years later. However that may have been, it was Clay who led the attack on the administration about the campaign in Florida. Protesting his deep respect for "the illustrious military chieftain" who commanded there, he yet condemned the hanging of the two Red Sticks, the execution of Arbuthnot and Ambrister, the taking of Pensacola.

From the moment Jackson read that speech he was Clay's enemy, and a warfare began that lasted twenty-five years. Every man, in fact, who in the course of the long debate that followed condemned the acts of General Jackson in Florida was written down an enemy on the tablets of his memory. He remained in Washington until the House had voted down every resolution unfavorable to his course, and he had thus won his first victory over Clay. Then he set forth on a northern journey which showed him the immense popularity he had in places like New York, Philadelphia, and Baltimore, and gave him an opportunity to increase it by the fine appearance he made in public. He returned to find that a Senate committee had reported unfavorably on his conduct, but the Senate never acted on the report, and on his journey homeward the people gave him every reason to believe that the great majority of his countrymen approved the votes of the lower house. As if to complete his triumph, he was soon called once more to Florida; and this time he entered Pensacola, not as a soldier invading a foreign province, but as the chief magistrate of an American territory. In February, 1821, after so many years of negotiation, Florida was bought by the United States. President Monroe appointed Jackson governor and commissioner to receive the province, and he, bidding farewell to the army, entered again upon the duties of a civil office.

Even in his farewell to his troops, Jackson took occasion to attack a policy recently favored by his superior, General Jacob Brown, and any one who knew Jackson might have guessed that the holding of a civil office would never keep him from violent courses, particularly in Pensacola. He held the office only a few months, for he was in wretched health. His wife, who was with him, tells in one of her letters how pale and solemn he was when he rode into Pensacola for the third time, and how ill he was while he was there. He resigned in October, but before he resigned he had made another cause of dispute with Spain. The retiring Spanish governor, Callava, was accused of attempting to carry away papers which were necessary to establish the property rights of a quadroon family. The correspondence on the subject led to a series of misunderstandings, and General Jackson was soon convinced that villainy was afoot. The upshot of the dispute was that the American governor put the Spanish governor in jail; and when the United States judge of West Florida, a curious character named Fromentin, tried to mend the matter with a writ of habeas corpus, he fared little better than Judge Hall of New Orleans had fared before him.

Mr. Parton's laborious investigation of this comical affair enables him to show that the estate over which the trouble arose was of no value whatever, and that Jackson's chivalrous impulse to defend a family he thought wronged led him into a very arbitrary and indefensible action. As usual, his motives were good, but his temper was not improved by his illness or by the fact that Callava, who seems to have been a worthy gentleman, was a Spaniard, and had been governor of Florida. Jackson had a rooted dislike of Spanish governors, and doubtless congratulated himself and the country that there would be no more of them in Florida, when, for the last time, he turned northward from Pensacola to seek The Hermitage and the rest which his diseased body sorely needed.

The Hermitage was by this time a good place to rest in, for it had grown to be a Southern plantation home, quite unlike the bare homes which sheltered the first settlers of that neighborhood, and it had its full share of the charm that belonged to that old Southern life. It was the seat of an abundant hospitality. The fame of its master drew thither interesting men from a distance. His benevolence, and the homely charity of his wife, made it a resort for many of the neighborhood whom they two had befriended, for young people fond of the simple amusements of those days, and for ministers of the Gospel, whom Mrs. Jackson, an extremely pious woman, liked especially to have about her. For his wife's sake, the general built a tiny church on the estate, and always treated with profound respect the religion which he himself had not professed, but which he honored because Mrs. Jackson was a Christian. Indeed, there is nothing in the man's whole life more honorable than his perfect loyalty to her. She was a simple, uncultivated, kind-hearted frontier woman, no longer attractive in person, and a great contrast to the courtly figure by her side when she and the general were in company. It is certainly true that the two used to smoke their reed pipes together before the fire after dinner, and that custom, to one ignorant of American life in the Southwest, would stamp them as persons of the lowest manners. Yet it is also true that "Aunt Rachel," as Mrs. Jackson was commonly called by younger people of the neighborhood, was loved and honored by all who knew her. The general had not merely fine manners, but that which is finer far than the finest manners: he had kindness for his slaves, hospitality for strangers, gentleness with women and children. Lafayette was at The Hermitage in 1825, and his noble nature was drawn to Jackson in a way quite impossible to understand if he was nothing more than the vindictive duelist, the headstrong brawler, the crusher out of Indians, the hater of Britons and Spaniards, which we know that he was. Lafayette found at The Hermitage the pistols which he himself had given to Washington and which, with many swords and other tokens of the public esteem, had come to the hero of New Orleans. The friend of Washington declared that the pistols had come to worthy hands, notwithstanding that his host was equally ready to display another weapon with the remark, "That is the pistol with which I killed Mr. Dickinson."
