Captain Joseph Llanos, by his letter without date, (although there can be no doubt that it comes from Boston) says, that he sailed from London with his vessel, (without mentioning its name) belonging to Don Philip Aguixxe de San Fadder, loaded with merchandise for Cadiz, amounting to nearly two hundred thousand current piastres, and that in the course of his voyage he was stopped by a privateer schooner of Newbury, called the Success, Felix Trask Captain, belonging to Nathaniel Tracy of said Newbury, and forcibly brought to this place, notwithstanding, that he assured the said Captain Tracy, that the cargo belonged entirely to Spaniards, and that he was convinced of it by the bills of laden found on board, notwithstanding which, that the said cargo has been sentenced as a lawful prize, although the papers exhibit no fraud; as will be seen by the process, which is copied in order to be presented to the honorable Congress, to which appeal is made. The Captains claim the protection of the honorable Congress, that of his Excellency M. Gerard, and that of Don Juan de Miralles; the navigation of the Spanish being very much injured by the privateers of this continent, there being three vessels belonging to this nation in the same situation as the above, brought in by different privateers. These three vessels also propose to appeal to the honorable Congress, and are resolved to defend the rights of the Spanish. Captain Joachin Garcia de Luca, commander of a Spanish ship with three masts, her crew Spanish, says, in his letter dated at Boston, the 3d of the present month, that he sailed from Cadiz for London, loaded with wines, oils, cochineal, and fruits, on the account and at the risk of Spaniards, and that he was stopped, on the 21st of December, 1778, when pursuing his voyage, by a privateer frigate, with the flag of the United States of America, which brought him to Beverly; that having learned that the owners of the said privateer were desirous, that the cargo of the Spanish vessel should be confiscated, he went to Boston, where the court of justice sits, before which he appeared on the 2d of the current month, not knowing at that time, but he should meet with the same fate, which his friend Don Joseph de Llanos has suffered with regard to his cargo, which was condemned on the 28th of last March. I, Don Juan de Miralles, truly certify, that the above was extracted from the letters which the Spanish Captains, Don Joseph de Llanos and Joachin Garcia de Luca, wrote to me, and which I received on the 19th current, at eight o'clock in the evening. DON JUAN DE MIRALLES. _Philadelphia, April 21, 1778._ * * * * * TO THE PRESIDENT OF CONGRESS. Translation. Philadelphia, May 3d, 1779. Sir,
