The fire was kept up until the water was over the gun-trucks, when attention was turned to getting the wounded and the crew out of the vessel. The Oneida, Captain Lee, seeing the condition of the Varuna, had rushed to her assistance, but was not needed, and the Morgan surrendered to her, having over fifty of her crew killed and wounded. She was set on fire by her commander.
In fifteen minutes from the time the Varuna was struck, she was on the bottom, with only her topgallant forecastle out of water. The officers and crew lost everything they possessed, no one thinking of leaving his station until driven thence by water.
The Federal vessels made their rendezvous at the Quarantine, some miles above the forts, and took possession of the camp of the Chalmette regiment of rebel sharpshooters, some of whom escaped, while the others surrendered, and were paroled. The officers were taken to the flag-ship and paroled. The wounded men of the various ships were now carefully attended to. The heroic dead who had fallen in defence of their flag were taken ashore, and laid in their last resting-place, in a manner worthy of the cause in which they had shed their blood, and the national flag was left floating over their graves. The Federal loss was 30 killed and 120 wounded. The loss of the rebels was very severe, some of the estimates making it as high as 800 or 1,000 in killed and wounded.
THE SURRENDER OF THE FORTS.
When the fleet started in its attempt to pass the forts, the mortar vessels opened a tremendous fire, which was continued until five o’clock, when they were signalled to cease. During the forenoon, Commodore Porter dispatched Captain Grant, in the Owasco, with a flag of truce, to demand the surrender of the forts. The vessel approached Fort St. Philip to within about a mile, when the batteries were opened upon her and five shots were fired, upon which she withdrew. The flag of truce was hauled down, but soon afterwards a boat flying a flag of truce at her bows, and the secession flag at her stern, approached, and Captain Grant went out and held a conference with the rebel officer. He offered an apology in behalf of his superior officer for the unintentional firing upon the flag of truce, declaring that its color had not been seen, and could not be distinguished in the distance. He then returned to the fort, and the bombs again commenced their thunders, which lasted until Commodore Porter ordered the fleet down the river.
Oh the 25th, Commodore Porter sent six of the mortar vessels to guard the bayous in the rear of Fort Jackson, when three of them, the Henry Janes, Kittatinny and Geo. W. Maryham, on the 26th, drifted off to Fort Livingston, a stronghold of the rebels, guarding one of the passages. There was a flag of truce flying on the fort, and on boats being sent ashore, they found the place deserted by all except several men, women and children, who resided on the island. The Federals found eleven 32-pounders, three 12-pound howitzers, two 24-pounders, one 8-inch columbiad, one 80-pound rifled cannon, one thousand 32-pound shot, and other articles of minor importance. The fort was in good condition, with all its property. It was left in charge of Acting Master Tamsen, of the U. S. navy.
On the 28th, Lieutenant-Colonel Higgins, commanding the forts, sent a communication to the Commodore, offering to surrender. The Harriet Lane (flag-ship) accordingly steamed up to the forts, and received the commander on board, when the articles of capitulation were drawn up and signed. Not to prolong the contest by very exacting terms, Commodore Porter received the forts and property, and allowed Brigadier-General Duncan, commander of coast defences, and Lieutenant-Colonel Higgins, commanding the forts, to retain their side arms, under parole. The other officers and privates were to retire on parole, giving up all arms and accoutrements, the United States to transport the men from the forts.
Three steamers of the rebel fleet remained, and were under the direction of Commander J. K. Mitchell. Lieutenant-Colonel Higgins said he had no command over them, and was not responsible for their conduct. While the flag of truce was up, and the capitulation was under conference, they towed the iron floating battery, Louisiana, to a place above the forts, set it on fire, and turned it adrift upon the Federal fleet. The guns soon becoming heated, began to discharge, throwing their shot around the river, and in a little while the battery itself exploded with a terrific report, scattering the fragments all over the river, and wounding one of their own men in Fort St. Philip.
As soon as the terms of capitulation were concluded and signed, Commodore Porter started for the rebel fleet. One vessel had been sunk by the Federal guns during the consultation, and another was taken by the Commodore. He immediately put the officers in close confinement, for the attempt to blow up the Federal vessels while under the flag of truce.
While the reduction and surrender of the forts was effected apparently by the fleet, it was evident that they could have held out in defiance of the bombardment for an indefinite period. The successful passage of the gunboat fleet threw an immense force above the forts, while a competent force remained below. In addition to this, General Butler had succeeded in finding a passage for a portion of his land forces through the channels in the rear of Fort St. Philip, and thus threatened the forts in a direction where they were easily vulnerable. Under these circumstances a considerable part of the garrison revolted, on the night of the 27th, refused to serve, and demanded a surrender, because defence was no longer of the least service to their main purpose, that of defending the approach to the city. The discontented part of the troops, about two hundred in number, were permitted to leave the fort, and they proceeded to the Quarantine and gave themselves up to General Butler. This timely co-operation of General Butler led to the decision of the commander, and on the following morning the capitulation was completed, and the national flag was restored to the walls of Forts Jackson and St. Philip.
