After I had finished the general business with which Congress had charged me, I consulted the several Ministers at the Court of France upon the proper measures to be taken, when such a flagrant violation of the laws of nations had been offered in the person of a public Minister, and solicited their intervention and assistance. They all declared, that however anxious they were to restore to his country a citizen, so valuable by his services, they had not the least hope, that any benefit would be derived from their interference, the British Court being as little disposed to gratify the Court of France, as they were to gratify the United States; and the unanimous opinion of these gentlemen further was, that nothing would determine the British to pursue a reasonable conduct in the present case, but the most exact retaliation on the part of Congress. For this purpose they advised, that one or more British prisoners of sufficient note and importance to cause a sensation by their own complaints, or those of their friends, to their Court, should be held as security for the safety of Mr Laurens, and that their mode of confinement and treatment should invariably follow the rule of the conduct of the British government towards him. In addition to the report, which I had the honor to make the 2d instant, I take the present opportunity of enclosing to Congress the duplicate account of the frigate Alliance's disbursements, by Messrs Gourlade and Moylan of L'Orient. The misfortune of Mr Palfrey left us without other resource, than an application to a mercantile house. The persons above mentioned offered their services, and were recommended. The sum total appeared both to the Minister Plenipotentiary and myself very considerable for the short stay of the vessel in port, and the charge of advanced officers' pay unprecedented; but Captain Barry had signed the original account, and M. Moylan's house had advanced the money, and offered every authentic voucher. I thought myself obliged to write from Brest, requesting Dr Franklin to order payment after necessary security. I found myself under the necessity of drawing, under the authority of Congress, for three hundred and fifty louis, on their Minister Plenipotentiary at the Court of France. Fifty of these were given to Mr Jackson on his departure for Holland. On my arrival at Boston, I borrowed on my private credit forty guineas, twentyfive of which have been paid for the purchase of saddles, and the expense of the journey, including that of an express with the despatches from France for the French Minister and army, and that of an escort of dragoons, which it became prudent, on account of my papers, to take from Danbury to a place a few miles on this side of the North River. I had recourse to the State of Rhode Island for horses, &c. a particular account of which will be given to the Board of War. I have the honor to be, with the greatest veneration, &c.
