This assumption of command entailed the putting of the ships in commission by publicly reading the orders appointing the commodore, and assigning him to command, and hoisting and saluting the flags. The officers previously appointed had been proceeding somewhat irregularly, doubtless, by going on with their preparations prior to this important ceremony. At any rate, in the latter part of December, 1775, or the early part of January, 1776--the date not being clear, the authorities not only differing, but in no single case venturing upon a definite statement--all things having been made ready, Commodore Hopkins with his staff officers entered the commodore's barge, lying at the foot of Walnut Street, and was rowed to the flagship. The wharves and houses facing the river were crowded with spectators to witness so momentous a ceremony as the commissioning of the first American fleet. It has been recorded that it was a bright, cold, clear winter morning. The barge picked its way among the floating ice cakes of the Delaware, and finally reached the Alfred. The commodore mounted the side, followed by his staff, and was received with due honors in the gangway by the captain and his officers in such full dress as they could muster. The crew and the marines were drawn up in orderly ranks in the waist and on the quarter deck. After the reading of the commodore's commission and the orders assigning him to the command of the fleet, Captain Dudley Saltonstall nodded his head to John Paul Jones, his executive officer. The young Scotsman, with, I imagine, a heart beating rarely, stepped forward and received from the veteran quartermaster the end of the halliards, to which, in the shape of a neatly rolled-up ball, was bent a handsome yellow silk flag, bearing the representation of a rattlesnake about to strike (and perhaps a pine tree also), with the significant legend "Don't tread on me." With his own hands the young lieutenant hauled the rolled-up ensign to the masthead, and then, with a slight twitch, he broke the stops and there blew out in the morning breeze, before the eyes of the commodore, his officers, the men of the ships, and the delighted spectators on shore, the first flag that ever flew from a regularly commissioned war ship of the United Colonies. The grand union flag, a red and white striped ensign with the English cross in the canton, was also hoisted. The flags were saluted by the booming of cannon from the batteries of the ships, and with cheers from the officers and men of the squadron and the people on the shore, and thus the transaction was completed, and the navy of the United States began to be.
