On the 7th of December, I had the honor to write to you from Brest, and my letters down to that date have contained accounts of our political affairs. Since which time, I have been taken up in preparations of a plan that would have turned out to the advantage of America; indeed, it exceeded my first expectations, and to my great surprise, the King of Spain had not only consented his forces should co-operate with us, but on the consideration of obtaining a necessary diversion, he had been induced by Count d'Estaing to approve my being detached into Canada with a French force. Nay, had the war continued, I think that, if not for love, at least on political motives, they would have consented to offer pecuniary assistance. The conditions of the peace I do not dwell upon. I hope they are such as will be agreeable in America. They have no doubt been sent from France, and the part that respects the United States will have been immediately forwarded for their ratification. I do not hope to send you the first tidings of a general peace. Yet I have prevailed upon a small vessel to alter her course, and my own servant is going with the despatches, to prevent either neglect or other accidental delays. On the moment of my arrival at Cadiz, I began a close correspondence with Mr Carmichael. It at first respected money matters, but soon took a still more important turn. Having been officially asked my advice upon his future conduct, I gave it in a letter, of which the enclosed is a copy. Whatever light my opinion may appear in at Madrid, or elsewhere, I think it is consistent with the dignity of the United States. Now, Sir, while enjoying the hope of being in a few weeks on the American shore, I have a letter from Mr Carmichael, wherein he requests my assistance at Madrid. How far it may serve him I do not know; but since I am thought useful, I shall yield to my zeal for the service of America, I readily give up personal gratifications. On my arrival at Madrid, I shall have the honor to give you my opinion of our situation there. Among the Spaniards we have but few well wishers, and as they, at the bottom, hate cordially the French, our alliance, though a political, is not a sentimental consideration with them. But I wish a settlement of boundaries may remove the more immediate prospects of dispute. It is, I believe, very important to America; the more so, as she became a national ally to France, a national enemy to Britain. But the Spaniards will be forever extravagant in their territorial notions, and very jealous of the increase of American wealth and power. But it is good policy for us to be upon friendly terms with them, and I wish on my return to Paris, that I may carry for Mr Jay some hopes of better success in his Spanish negotiation.
