An event was soon to happen which seemed for the time an irreparable disaster to the American cause. Commodore Daniel T. Patterson, in command of the American naval forces, on learning of the approach of the British fleet, sent Lieutenant Thomas Ap Catesby Jones, with five gunboats, one tender, and a dispatch boat toward the passes out to Ship Island, to watch the movements of the British vessels. This little flotilla, barely enough for scout duty at sea, was the extent of our naval forces in the Gulf waters near. The orders were to fall back, if necessary, from near Cat Island to the Rigolets; and there, if hard pressed, to sink or be sunk by the enemy. Moving in waters too shallow for the large English ships to pursue, until the thirteenth, Lieutenant Jones sailed for Bay St. Louis. Sighting a large number of the enemy's barges steering for Pass Christian, he headed for the Rigolets. But the wind having died away and an adverse current set in, the little fleet could get no farther than the channel inside of Melheureux Island, being there partially grounded. Early on the morning of the fourteenth, a flotilla of barges formed in line was discovered coming from the direction of the enemy's ships, evidently to overtake and attack the becalmed gunboats. The two tenders, lying beyond the aid of the latter, were captured after a spirited resistance. The guns of these were now turned upon Lieutenant Jones' gunboats in a combined attack of the fleet of barges, forty-five in number, and a supporting squad of marines. The total equipment was twelve hundred men and forty-five pieces of artillery. The American defensive forces were seven small gunboats, manned by thirty guns and one hundred and eighty men. The enemy's oarsmen advanced their entire fleet in line of battle until the fire from the gunboats caused severe losses and some confusion in the movements of the barges. They then separated in three divisions and renewed the attack. The battle became general, and was contested fiercely for nearly two hours, when the gunboats, overpowered by numbers, were forced to surrender, losing six men killed and thirty-five wounded, among the latter Lieutenants Jones, Speddin, and McKeever, each in command of a boat. Several barges of the enemy were sunk, while their losses in killed and wounded were estimated at two to three hundred. Among the wounded were Captain Lockyer, in command, and other officers.
