On the 12th of July, four days before the capture of the "Nautilus," the "Constitution" had sailed from Chesapeake Bay, under Captain Hull, bound for New York. Late on the afternoon of the 16th, the day on which the "Nautilus" was taken, she too fell in with the British squadron. For three long and weary days and nights the enemy pursued her, and during all that time the zeal and courage of her officers never flagged, and no means were left untried that might assist in her escape. The untiring efforts of Captain Hull were seconded by his first lieutenant, Charles Morris, the same who had been with Decatur when he burned the "Philadelphia" in the harbor of Tripoli, and certainly one of the best officers that ever fought under the American flag. He shall tell in his own words the story of THE CHASE OF THE "CONSTITUTION." We had proceeded beyond the Delaware, but out of sight of the land, when on the afternoon of the 16th we discovered four vessels at a great distance to the northwest and a single ship to the northeast, from which quarter a light wind was then blowing. The wind changed to the southward about sunset, which brought us to windward, and we stood for the ship, the wind being very light. The chase was evidently a frigate, and the first impression was that she might be a part of Commodore Rodgers's squadron. By eleven P.M. we were within signal distance, and it was soon apparent she was not an American vessel of war. There being no apprehension that a British frigate would make any attempt to avoid an engagement, Captain Hull felt justified in delaying any nearer approach till daylight, when our newly-collected and imperfectly-disciplined men would be less likely to be thrown into confusion. The ship was accordingly brought to the wind with her head to the southward and westward under easy sail, with a light wind from the northwest. The other ship did the same at about two miles' distance. The watch not on duty were allowed to sleep at their quarters, and the officers slept in the same manner. As the following morning opened upon us it disclosed our companion of the night to be a large frigate just without gunshot, on the lee quarter, and a ship-of-the-line and three other frigates, a brig, and a schooner, about two miles nearly astern, with all sails set standing for us, with English colors flying.
