As the duration of this peace cannot be counted on with certainty, and we look forward to the necessity of coercion by cruises on their coast, to be kept up during the whole of their cruising season, you will be pleased to inform yourself, as minutely as possible, of every circumstance which may influence or guide us in undertaking and conducting such an operation, making your communications by safe opportunities. I must recommend to your particular notice Captain O’Bryan, one of the captives, from whom we have received a great deal of useful information. The zeal which he has displayed under the trying circumstances of his present situation, has been very distinguished. You will find him intimately acquainted with the manner in which, and characters with whom, business is to be done there, and perhaps he may be an useful instrument to you, especially in the outset of your undertaking, which will require the utmost caution and the best information. He will be able to give you the characters of the European Consuls there, though you will, probably, not think it prudent to repose confidence in any of them. Should you be able successfully to accomplish the objects of your mission in time to convey notice of it to us as early as possible during the next session of Congress, which meets in the beginning of November and rises the 4th of March, it would have a very pleasing effect. I am, with great esteem, Sir, your most obedient and most humble servant, Th: Jefferson. LETTER CXI.--TO MR. PINCKNEY, June 11, 1792 TO MR. PINCKNEY. Philadelphia, June 11, 1792.
