But, while Congress had been therefore preparing to build the navy, the regular marine committee had not been idle. By strenuous effort the committee assembled a squadron. A merchant vessel called the Black Prince, which had lately arrived from London under the command of John Barry (afterward a famous American commodore), was purchased and renamed the Alfred, after King Alfred the Great, who is commonly believed to be the founder of the British navy. She was a small, stanch trading vessel, very heavily timbered, and with unusually stout scantlings for a ship of her class, although of course not equal to a properly constructed ship of war. The committee armed her with twenty 9-pounders on the main deck, and four smaller guns, possibly 6- or 4-pounders, on the forecastle and poop, and she was placed under the command of Captain Dudley Saltonstall. Jones, whose name stood first on the list of first lieutenants, was appointed her executive officer. Hopkins selected her for his flagship. Jones had been offered the command of one of the smaller vessels of the squadron, but elected to fill his present station, as presenting more opportunities for acquiring information and seeing service. His experience in armed vessels had been limited; he knew but little of the requirements of a man-of-war, and deemed he could best fit himself for that higher command to which he aspired and determined to deserve by beginning his service under older and more experienced officers--a wise decision. The next important vessel was another converted merchantman, originally called the Sally, now named the Columbus, after the great discoverer. She was a full-rigged ship of slightly less force and armament than the Alfred, commanded by Captain Abraham Whipple, already distinguished in a privateering way. In addition to these there were two brigs called the Andrea Doria and the Cabot, commanded by Captains Nicholas Biddle and John Burroughs Hopkins, a son of the commander-in-chief. The Andrea Doria and Cabot carried fourteen 4-pounders each. Hopkins arrived at Philadelphia in December, 1775, in the brig Katy, of the Rhode Island navy, which was at once taken into the Continental service and renamed the Providence, after the commander's native town. She carried twelve light guns, 4-pounders. There were also secured a ten-gun schooner called the Hornet, and the Wasp and Fly, two eight-gun schooners or tenders, one of which Jones had refused. The work of outfitting these ships as generously as the meager resources of the colonies permitted had been carried on assiduously before the arrival of the commander-in-chief, whose first duty, when he reached Philadelphia, was formally to assume the command.
