On the 20th of November, 1820, Farragut again landed in the United States, having been absent four years and a half. He felt himself a stranger, having left as a mere boy, and knowing no one but Commodore Porter and his family. His examination soon followed, and was passed; but apparently not quite to his own satisfaction. A period of comparative quiet followed, spent principally in Norfolk, Virginia, during which he formed the attachment which resulted in his first marriage. In May, 1822, he was again ordered to sea in the sloop-of-war John Adams, in which he made a short cruise in the Gulf of Mexico and to Vera Cruz, where the Spanish power in Mexico was then making its last stand in the well-known fortress, San Juan de Ulloa. The ship returned to the United States early in December, 1822, when Farragut found the Mosquito fleet, as it was called, fitting out against the pirates of the Caribbean Sea. Learning that it was to be commanded by his old captain, Commodore David Porter, he asked for and obtained orders to the Greyhound, one of the small vessels composing it, commanded by Lieutenant John Porter, a brother of the commodore. Since the peace with Great Britain, Captain Porter had been a member of the Board of Navy Commissioners; a body of three officers appointed by an act of Congress passed early in 1815, whose duties were to administer the affairs of the navy under the supervision of the Secretary. Meanwhile the sufferings, not only of American property but of the persons of American citizens, from the prevalence of piracy in the Caribbean Sea, had become unendurable. Ordinary naval vessels were, from their size, unable to enforce a repression for which it was necessary to follow the freebooters and their petty craft into their lairs among the lagoons and creeks of the West India islands. The general outcry rousing the Government to the necessity of further exertion, Captain Porter offered his services to extirpate the nuisance; with the understanding that he was to have and fit out the kind of force he thought necessary for the service. He resigned his position on the board on the 31st of December, 1822; but before that date he had bought and begun to equip eight Chesapeake schooners, of fifty to sixty tons burden, of which the Greyhound, Farragut's new vessel, was one. He also built five rowing barges, unusually large, pulling twenty oars. With these, supported by the ordinary man-of-war schooners, of which several were already in the service, and by the sloops-of-war, he expected to drive the pirates not merely off the sea, but out of their hiding-places.
