The Gulf and Inland Waters / The Navy in the Civil War. Volume 3.

Meanwhile Commander Porter remained in command below the forts. The morning after the passage of the fleet he sent a demand for their surrender, which was refused. Learning that the Louisiana and some other boats had escaped the general destruction, and not aware of their real condition, he began to take measures for the safety of his mortar-schooners. They were sent down the river to Pilot Town, with the Portsmouth as convoy, and with orders to fit for sea. Six were sent off at once to the rear of Fort Jackson, to blockade the bayous that ramify through that low land; while the Miami and Sachem were sent in the other direction, behind St. Philip, to assist the troops to land.

On the 27th, Porter, having received official information of the fall of the city, notified Colonel Higgins of the fact, and again demanded the surrender, offering favorable conditions. Meanwhile insubordination was rife in the garrison, which found itself hemmed in on all sides. At midnight of the 27th, the troops rose, seized the guard and posterns, reversed the field pieces commanding the gates, and began to spike the guns. Many of them left the fort with their arms; and the rest, except one company of planters, firmly refused to fight any longer. The men were largely foreigners, and with little interest in the Secession cause; but they also probably saw that continued resistance and hardship could not result in ultimate success. The water-way above and below being in the hands of the hostile navy, all communication was cut off by the nature of the country and the state of the river; there could therefore be but one issue to a prolonged contest. The crime of the men was heinous, but it only hastened the end. To avoid a humiliating disaster, General Duncan accepted the offered terms on the 28th. The officers were permitted to retain their side arms, and the troops composing the garrison to depart, on parole not to serve till exchanged. At 2.30 P.M. the forts were formally delivered to the navy, and the United States flag once more hoisted over them.

The Confederate naval officers were not parties to the capitulation, which was drawn up and signed on board Porter's flag-ship, the Harriet Lane. While the representatives were seated in her cabin, flags of truce flying from her masthead and from the forts, the Louisiana was fired by her commander and came drifting down the river in flames. Her guns discharged themselves as the heat reached their charges, and when she came abreast Fort St. Philip she blew up, killing a Confederate soldier and nearly killing Captain McIntosh, her former commander, who was lying there mortally wounded. This act caused great indignation at the time among the United States officers present. Commander Mitchell afterward gave explanations which were accepted as satisfactory by Mr. Welles, the Secretary of the Navy. He said that the Louisiana was secured to the opposite shore from the fleet, three-quarters of a mile above, and that an attempt had been made to drown the magazine. As proof of good faith he had sent a lieutenant to notify Porter of the probable failure of that attempt. It remains, however, a curious want of foresight in a naval man not to anticipate that the hempen fasts, which alone secured her, would be destroyed, and that the vessel thus cast loose would drift down with the stream. Conceding fully the mutual independence of army and navy, it is yet objectionable that while one is treating under flag of truce, the other should be sending down burning vessels, whether carelessly or maliciously, upon an unsuspecting enemy.

When taken possession of, Fort Jackson was found to have suffered greatly. The ground inside and out was plowed by the falling shell; the levee had been cut in many places, letting water into the fort; the casemates were shattered, guns dismounted and gun-carriages destroyed; all the buildings within the walls had been burned. Yet it was far from being reduced to an indefensible condition by six days' bombardment, could it have continued to receive supplies and reinforcements. The loss of the garrison had been 14 killed and 39 wounded.

The question of the efficacy of mortar-firing was raised in this as in other instances. Granting its inability to compel the surrender, it remains certain that Fort Jackson, though the stronger work, inflicted much less damage upon the passing fleet than did St. Philip. The direct testimony of Commander De Camp of the Iroquois, and an examination of the injuries received by the ships, when clearly specified, shows this. As both posts had been under one commander, it may be inferred that the difference in execution was due partly to the exhaustion of the garrison, and partly to the constant fire of the mortar flotilla during the time of the passage; both effects of the bombardment.

The exterior line of the defences of New Orleans being thus pierced in its central and strongest point, the remaining works—Forts Pike and Macomb guarding the approaches by way of Lake Pontchartrain, Livingston at Barrataria Bay, Berwick at Berwick Bay, and others of less importance—constituting that line were hastily abandoned. Such guns as could be saved, with others from various quarters, were hurried away to Vicksburg, which had already been selected as the next point for defence, and its fortifications begun. The whole delta of the Mississippi was thus opened to the advance of the Union forces. This was followed a few days later by the evacuation of Pensacola, for which the enemy had been preparing since the end of February, when the disaster at Donelson had made it necessary to strip other points of troops. The heavy guns had been removed, though not to New Orleans. The defenceless condition of the place was partly known to the officer commanding at Fort Pickens, but no one could spare him force enough to test it. At the time of its final abandonment, Commander Porter, who after the surrender of the forts had proceeded to Mobile with the steamers of the mortar flotilla, was lying off that bar. Seeing a brilliant light in the direction of Pensacola at 2 A.M. on the 10th of May, he stood for the entrance, arriving at daylight. The army and navy took possession the same day, and this fine harbor was now again available as a naval station for the United States.

After New Orleans had been occupied by the army, Farragut sent seven vessels, under the command of Captain Craven of the Brooklyn, up the river. Baton Rouge and Natchez surrendered when summoned; but at Vicksburg, on the 22d of May, Commander S.P. Lee was met with a refusal. On the 9th of June the gunboats Wissahickon and Itasca, being sent down to look after some earthworks which the Confederates were reported to be throwing up at Grand Gulf, found there a battery of rifle guns completed, and were pretty roughly handled in the encounter which followed. On the 18th of June the Brooklyn and Richmond anchored below Vicksburg, and shortly after the flag-officer came in person with the Hartford, accompanied by Commander Porter with the steamers and seventeen schooners of the mortar flotilla. The flag-officer did not think it possible to reduce the place without a land force, but the orders of the Department were peremptory that the Mississippi should be cleared. From Vicksburg to Memphis the high land did not touch the river on the east bank, and Memphis with all above it had now fallen. Vicksburg at that time stood, the sole seriously defended point.

The condition of the fleet was at this time a cause of serious concern to the flag-officer. The hulls had been much injured by the enemy's fire, and by frequent collisions in the lower river, due to the rapid current and the alarms of fire-rafts. The engines, hastily built for the gunboats, and worn in other ships by a cruise now nearing its usual end, were in need of extensive repairs. The maintenance of the coal-supply for a large squadron, five hundred miles up a crooked river in a hostile country, was in itself no small anxiety; involving as it did carriage of the coal against the current, the provision of convoys to protect the supply vessels against guerillas, and the employment of pilots; few of whom were to be found, as they naturally favored the enemy, and had gone away. The river was drawing near the time of lowest water, and the flag-ship herself got aground under very critical circumstances, having had to take out her coal and shot, and had even begun on her guns, two of which were out when she floated off. The term of enlistment of many of the crews had ended and they were clamoring for their discharge, and the unhealthy climate had already caused much illness. It was evident from the very first that Vicksburg could only be taken and held by a land force, but the Government in Washington were urgent and Farragut determined to run by the batteries. This was the first attempt; but there were afterward so many similar dashes over the same spot, by fleets or single vessels, that the scene demands a brief description.
