Within an hour after he had received news of the declaration of war, Commodore Rodgers had his squadron under way, and dropped down New York Bay to the ocean. Under his command were the flag-ship "President" of forty-four guns, the "Essex" thirty-two, and the "Hornet" eighteen. In the lower bay these vessels were joined by the "United States" forty-four, the "Congress" thirty-eight, and the "Argus" sixteen. On June 21, 1812, three days after the declaration of war, the whole squadron passed Sandy Hook, and stood out into the ocean. It is probable that the remarkable celerity of Commodore Rodgers's departure was due, in part, to the fear that the authorities would revive the obnoxious order laying up the ships in port. His chief object, however, was to overhaul a large fleet of British merchantmen that had recently left the West Indies, and, according to all calculations, should have been in the vicinity of New York at that time. All sail was accordingly crowded upon the ships, and the squadron set out in hot pursuit. For two days the monotony of the horizon was broken by no sail; but on the third a ship was espied in the distance, which was made out to be an enemy's frigate, after which chase was made by the whole squadron. A fresh breeze was blowing, and both chase and pursuers were running free before the wind. As sail after sail was crowded upon the ships, the smaller vessels, with their lesser expanse of canvas, began to fall behind; and in a few hours the frigate "President" had gradually drawn away from the fleet, and was rapidly gaining on the enemy. The sail had been spied at six o'clock in the morning, and at four P.M. the flag-ship had come within gunshot of the chase. The wind then fell; and the chase, being long out of port and light, began to gain on her heavier adversary. Both vessels now began to prepare for a little gunnery. On the English vessel, which proved to be the "Belvidera," thirty-six, the sailors were busily engaged in shifting long eighteens and carronades to the stern, making a battery of stern-chasers mounting four guns. The action was opened by a gun from the bow of the "President," sighted and fired by Commodore Rodgers himself; so that this officer may be said to have fired the first gun of the war. His shot was a good one, hulling the enemy. A second shot from one of the guns of the first division broke off the muzzle of one of the "Belvidera's" stern-chasers; and a third shot, fired by Commodore Rodgers, crashed into the stern of the chase, killing two men, and wounding several others. Certainly in their first action the Yankees showed no lack of skill in gunnery.
