Neither Spain nor Great Britain had ever given over the hope of dividing the young Republic and of acquiring for themselves portions of its territory. The Spanish especially had been active and unceasing in their intrigues to this end, their efforts being directed, of course, to the acquisition of the lands adjacent to them and bordering on the Mississippi and the Ohio.[776] In this work more than one American was in their pay. Chief of these Spanish agents was James Wilkinson, who had been a pensioner of Spain from 1787,[777] and so continued until at least 1807, the bribe money coming into his hands for several years after he had been placed in command of the armies of the United States.[778]

None of these plots influenced the pioneers to wish to become Spanish subjects; the most that they ever desired, even at the height of their dissatisfaction with the American Government, was independence from what they felt to be the domination of the East. In 1796 this feeling reached its climax in the Kentucky secession movement, one of its most active leaders being Wilkinson, who declared his purpose of becoming "the Washington of the West."[779]

By 1805, however, the allegiance of the pioneers to the Nation was as firm as that of any other part of the Republic. They had become exasperated to the point of violence against Spanish officials, Spanish soldiers, and the Spanish Government. They regarded the Spanish provinces of the Floridas and of Mexico as mere satrapies of a hated foreign autocracy; and this indeed was the case. Everywhere west of the Alleghanies the feeling was universal that these lands on the south and southwest, held in subjection by an ancient despotism, should be "revolutionized" and "liberated"; and this feeling was shared by great numbers of people of the Eastern States.

Moreover, that spirit of expansion—of taking and occupying the unused and misused lands upon our borders—which has been so marked through American history, was then burning fiercely in every Western breast. The depredations of the Spaniards had finally lashed almost to a frenzy the resentment which had for years been increasing in the States bordering upon the Mississippi. All were anxious to descend with fire and sword upon the offending Spaniards.

Indeed, all over the Nation the conviction was strong that war with Spain was inevitable. Even the ultra-pacific Jefferson was driven to this conclusion; and, in less than ten months after Aaron Burr ceased to be Vice-President, and while he was making his first journey through the West and Southwest, the President, in two Messages to Congress, scathingly arraigned Spanish misdeeds and all but avowed that a state of war actually existed.[780]

Such, in broad outline, was the general state of things when Aaron Burr, his political and personal fortunes wrecked, cast about for a place to go and for work to do. He could not return to his practice in New York; there his enemies were in absolute control and he was under indictment for having challenged Hamilton. The coroner's jury also returned an inquest of murder against Burr and two of his friends, and warrants for their arrest were issued. In New Jersey, too, an indictment for murder hung over him.[781]

Only in the fresh and undeveloped West did a new life and a new career seem possible. Many projects filled his mind—everything was possible in that inviting region beyond the mountains. He thought of forming a company to dig a canal around the falls of the Ohio and to build a bridge over that river, connecting Louisville with the Indiana shore. He considered settling lands in the vast dominions beyond the Mississippi which the Nation had newly acquired from Spain. A return to public life as Representative in Congress from Tennessee passed through his mind.

But one plan in particular fitted the situation which the apparently certain war with Spain created. Nearly ten years earlier,[782] Hamilton had conceived the idea of the conquest of the Spanish possessions adjacent to us, and he had sought to enlist the Government in support of the project of Miranda to revolutionize Venezuela.[783] Aaron Burr had proposed the invasion and capture of the Floridas, Louisiana, and Mexico two years before Hamilton embraced the project,[784] and the desire to carry out the plan continued strong within him. Circumstances seemed to make the accomplishment of it feasible. At all events, a journey through the West would enlighten him, as well as make clearer the practicability of his other schemes.

Now occurred the most unfortunate and disgraceful incident of Burr's life. In order to get money for his Mexican adventure, Burr played upon the British Minister's hostile feelings toward America and, in doing so, used downright falsehood. Although it was unknown at the time and not out of keeping with the unwritten rules of the game called diplomacy as then played, and although it had no effect upon the thrilling events that brought Burr before Marshall, so inextricably has this shameful circumstance been woven into the story of the Burr conspiracy, that mention of it must be made. It was the first thoroughly dishonorable act of Burr's tempestuous career.[785]

Five months after Pickering, Griswold, and other New England Federalists had approached Anthony Merry with their plan to divide the Union, Burr prepared to follow their example. He first sounded that diplomat through a British officer, one Colonel Charles Williamson. The object of the New England Senators and Representatives had been to separate their own and other Northern States from the Union; the proposition that Williamson now made to the British Minister was that Burr might do the same thing for the Western States.[786] It was well known that the break-up of the Republic was expected and hoped for by the British Government, as well as by the Spaniards, and Williamson was not surprised when he found Merry as favorably disposed toward a scheme for separation of the States beyond the Alleghanies as he had been hospitable to the plan for the secession of New England.
