The expedition of the Duc de Crillon is important in many views; should it succeed, it will be such a blow to the British as must hasten a negotiation, though it may probably obstruct a peace; at any rate, the possession of the Island must cut the sinews of their Mediterranean trade. Your apprehensions about being sent to Corunna, will, I hope, have been groundless, as Captain Gillon's ship is not the property of, or under the direction of the United States. So far as Mr Jay's good offices can be serviceable, they undoubtedly will be extended. He will not think himself obliged to involve the United States in the expense or disgrace of Captain Gillon's misconduct, if, as is alleged, he has really behaved improperly. Should he determine to interfere, Congress make no doubt but you will conform to his intentions; and they rely upon your zeal and activity in the discharge of such trusts, as he may think proper, since he alone can judge of the best application of them, and will not deprive himself of the advantages, which your assistance and information may afford, without being determined by weighty and important considerations. It gives great pleasure here, to hear of the step that Spain is taking, for opening a treaty with us. The delays in that business begin to be resented by the people of this country, the more forcibly, as they felt a high degree of respect for the Court, and much attachment to the people of Spain, in return for the good offices that they had done them. The great cause of the delay being now (as we hear) removed, I doubt not that the candor of the negotiators, and the clear views that they both have of the interest, which Spain and America may mutually derive from an intimate union, will remove all other difficulties to the wished for connexion. We have no other news on this side the water, than that the enemy have evacuated Wilmington. You, who know the spirit of disaffection which prevailed in some parts of North Carolina, and the commerce which it is capable of carrying on, particularly at this time, in articles for the supply of the West India markets, will see the important sacrifice the enemy have been obliged to make in thus quitting this post, and abandoning the only friends in America, upon whose fidelity and attachment they could rely. I need not repeat to you, that I shall at all times think myself happy in hearing from you, independent of the advantage that the public may derive from your letters. They will be particularly agreeable to me, as they may be made the means of increasing the number of friends, which your zeal and attention has already procured you. I am, Sir, with great esteem, &c.
