The chase was slow in responding to the fire; and although her commander, Capt. Byron, sighted the guns for the first few discharges himself, his aim was by no means so good as that of the Americans. The British showed great energy, however, in defending their ship. Not content with the stern guns already mounted, they shifted to the stern ports two long eighteen-pounders on the main deck, and two thirty-two-pound carronades on the quarter-deck. With these they kept up a brisk fire, which soon became effective, many shots cutting the rigging of the "President," while one plunged down upon the deck, killing a midshipman and two or three men. But the superiority of the American gunnery was beginning to tell, when, at a critical moment, a main-deck gun, on the "President," burst with a stunning report; and the flying fragments killed or wounded sixteen men. The force of the explosion shattered the forecastle deck. Commodore Rodgers was thrown high into the air, and, falling heavily on the deck, suffered a painful fracture of the leg. The crew was at once thrown into confusion and almost panic. Every gun was looked upon with suspicion. Encouraged by this confusion, the enemy worked his stern guns with renewed vigor, and at the same time lightened his ship by cutting away boats and anchors, and starting fourteen tons of water. Thus lightened, she began to draw away from the "President;" perceiving which, the latter ship yawed several times, and let fly full broadsides at the escaping chase. The shot rattled among the spars of the "Belvidera," but the nimble topmen quickly repaired all damages; and the British ship slowly but steadily forged ahead. Seeing no hope of overtaking her, Rodgers ordered the chase abandoned; and the American squadron again took up its search for the fleet of British merchantmen.
