The opinion, that in the event of war between Great Britain and Spain, Louisiana would be invaded from Canada, was not a mere suggestion for the purpose of aiding the negotiations at Madrid. It was seriously adopted by the American government; and the attention of the executive was turned to the measures which it would be proper to take, should application be made for permission to march a body of troops, through the unsettled territories of the United States, into the dominions of Spain; or should the attempt be made to march them, without permission. Among the circumstances which contributed to the opinion that, in the event of war, the arms of Great Britain would be directed against the settlements of Spain in America, was the continuance of Lord Dorchester in the government of Canada. This nobleman had intimated a wish to visit New York on his return to England; but the prospect of a rupture with Spain had determined him to remain in Canada. Under the pretext of making his acknowledgments for the readiness with which his desire to pass through New York had been acceded to, his lordship despatched Major Beck with, a member of his family, to sound the American government, and if possible, to ascertain its dispositions towards the two nations. Alluding to the negotiations which had been commenced in London, this gentleman endeavoured to assign a satisfactory cause for the delays which had intervened. It was not improbable, he said, that these delays, and some other circumstances, might have impressed Mr. Morris with an idea of backwardness on the part of the British ministry. His lordship, however, had directed him to say, that an inference of this sort would not, in his opinion, be well founded, as he had reason to believe that the British cabinet was inclined not only towards a friendly intercourse, but towards an alliance with the United States. Major Beckwith represented the particular ground of quarrel as one which ought to interest all commercial nations in favour of the views of Great Britain; and, from that circumstance, he presumed that, should a war ensue, the United States would find their interest in taking part with Britain, rather than with Spain. After expressing the concern with which Lord Dorchester had heard of the depredations of the savages on the western frontier of the United States, he declared that his lordship, so far from countenancing these depredations, had taken every proper opportunity to impress upon the Indians a pacific disposition; and that, on his first hearing of the outrages lately committed, he had sent a messenger to endeavour to prevent them. Major Beckwith further intimated, that the perpetrators of the late murders were banditti, composed chiefly of Creeks and Cherokees, in the Spanish interest, over whom the governor of Canada possessed no influence.
