His friendship for Aaron Burr came very near involving him in serious difficulties. In 1805, when Burr was on his first visit to the Southwest, he went to Nashville, and was entertained most cordially at The Hermitage. He was there again on his return, and made with his host a contract for boats and supplies to be used in that mysterious enterprise which has so puzzled American historians. Burr declared he had no designs hostile to the United States, and Jackson believed him. When, a year later, the whole country was in a sort of panic over Burr's suspected treason, Jackson offered to President Jefferson the services of the militia under his command, and promptly took measures to thwart any treasonable movement that might be afoot in the West; but he was soon convinced that Burr was suspected unjustly, and never for a moment deserted him in his trouble. He went to Richmond to testify at his trial, and while there made a public speech full of bitterness against those who, as he thought, were persecuting his friend. He himself was at first strongly suspected of complicity in Burr's project, but there is absolutely no reason to believe that Andrew Jackson ever in his life looked upon an enemy of his country otherwise than as his own mortal foe. His faults were many, but he loved his country simply, and with all his heart. It seems clear, however, that Jackson, and in fact the whole Southwest, sympathized very strongly with the design which many in that quarter at first thought Burr to entertain; the design, namely, of seizing West Florida or Texas, or perhaps both. The United States were at that time, as they were before and after, very close to war with Spain. Spain still had possession of the Floridas, although the United States claimed that West Florida, extending along the Gulf coast from the Perdido River to the "Island of New Orleans," was included in the Louisiana purchase. To drive the Spaniards out of West Florida was an ardent desire of Jackson's. Ten years before, when the Eastern States had shown little interest in the development of the Southwest, and had seemed to prefer commercial privileges with the Spanish colonies to the free navigation of the Mississippi, which the Western country needed for its development, Spanish agents had endeavored to stir up disaffection in the Southwest, looking to the separation of that region from the Union. At that time, many people in the East, knowing little of the Westerners, had suspected them of lending an ear to Spain's tempting whispers. That was one reason why such a panic arose over Burr, for he had always been a champion of the Southwest, and the pioneers liked him. After the failure and disgrace of Burr the stage was cleared for another leader in the southwestward movement. And who so likely to take the role as the patriotic and warlike general of the Tennessee militia?
