The boy was but thirteen when his father, in 1798, was called into the naval service of his country in the spirited effort made by President Adams to resist the aggressions of France upon the ocean. He took the command of a small frigate, built under his direction in Rhode Island, named the General Greene, and carried with him to sea his son Oliver as a midshipman, at the express solicitation of the youth. The General Greene was actively employed in the waters of the Gulf of Mexico, giving all its officers abundant opportunity for practice in the infant service. The French war flurry after a while blew over, as the Directory, the mainspring of these aggressions, lost power; peace was patched up, and Jefferson shortly after inaugurated an unwholesome pacific policy by a sweeping reduction of the navy, as if it were not small enough already. In this mutilating operation the elder Perry was dropped, the younger one fortunately retained. The navy, however, was soon revived by the demands of the nation to resist the iniquitous and insulting depredations upon life and property inflicted by the Barbary powers. The United States had borne far too patiently with these injuries, though she had the honor of being in advance of the old powers of Europe in resisting them. The Mediterranean became the scene of many a chivalrous exploit of our early officers, a score of whom, headed by Preble, Bainbridge, Decatur, Somers, and others of that stamp of fiery and indomitable valor, gained immortal laurels by their deeds of daring in conflict with the infidel. The young Perry served as midshipman in the frigate Adams, which sailed from Newport, in 1802, to join Commodore Morris' command at Gibraltar. His ship was for some time employed in blockading a Tripolitan at that port; a tedious but instructive service in manoeuvring, at the close of which Perry, in consequence of his accomplishments, was promoted by his captain to the duties of a lieutenant. The frigate was then employed as a convoy, making the tour of the northern ports. This gave Perry an opportunity to study scenes of the old world, which can never lose their influence in the formation of the man of education and refinement.
