il) DAVID D. PORTEE, ADMIRAL, U. S. N. In command of the mortar-fleet &t> Forts Jackson and St. Philip. On the 23d instant I represented the state of affairs to the flag-officer, and he concluded to move on past the works, which I felt sure he could do with but little loss to his squadron. He recognized the importance of making an immediate attack, and called a council of the commanders of vessels, which resulted in a determination to pass the forts that night. The movement was postponed, however, until the next morning, for the reason that the carpenters of one of the larger ships were at work down the river, and the commander did not wish to proceed without them. The ironclad Louisiana had now made her appearance, and her commander was being strongly urged by General Duncan to drop down below the forts [see the map, p. 96] and open fire upon the fleet with his heavy rifle-guns. On the 22d General Duncan wrote to Commander Mitchell from Fort Jackson: mies, and the whole fire of Fort Jackson was concentrated upon them. I had been informed of the intended movement by Farragut, so was ready to redouble the fire of the mortars at the proper time with good effect. In Farragut’s words: “ Commander Porter, however, kept up such a tremendous fire on them from the mortars that the enemy's shot did the gun-boats no injury, and the cable was separated and their connection broken sufficiently to pass through on the left bank of the river.” The work of the mortar-fleet was now almost over. We had kept up a heavy fire night and day for nearly 5 days — about 2800 shells every 24 hours; in all about 16,800 shells. The men were nearly worn out for want of sleep and rest. The ammunition was giving out, one of the schooners was sunk, and although the rest had received little actual damage from the enemy’s shot, they were badly shaken up by the concussion of the mortars. RIVER-SIDE INTERIOR OF FORT ST. PHILIP. terrible precision with which your formidable vessels hailed down their tons of bursting shell upon the devoted fort made it impossible for us to obtain either rapidity or accuracy of fire, and thus rendered the passage comparatively easy. There was no very considerable damage done to our batteries, but few of the guns being dismounted by your fire; everything else in and around the fort was destroyed.” I was not ignorant of the state of affairs in the fort; for, on the third day of the bombardment, a deserter presented himself and gave us an account of the havoc created by our shells, although I had doubts of the entire truth of his statements. He represented that hundreds of shells had fallen into the fort, breaking in the bomb-proofs, setting fire to the citadel, and flooding the interior by cutting the levees. He also stated that the soldiers were in a desperate and demoralized condition. This was all very encouraging to us, and so stimulated the crews of the mortar-boats that they worked with unflagging zeal and energy. I took the deserter to Farragut, who, although impressed by his statement, was not quite prepared to take advantage of the opportunity; for at this time the line of hulks across the river was considered an insurmountable obstruction, and it was determined to examine and, if possible, remove it before the advance of the fleet. On the night of the 20th an expedition was fitted out for the purpose of breaking the chain which was supposed to extend from one shore to the other. Two steamers, the Pinola, Lieutenant Crosby, and Itasca, Lieutenant Caldwell, were detailed for the purpose and placed under the direction of Captain Bell, chief-of-staff. Although the attempt was made under cover of darkness, the sharp eyes of the Confederate gunners soon discovered their ene- Edward Higgins, dated April 4th, 1872, which I received in answer to my inquiry on the subject: “ Tour mortar-vessels were placed in position on the afternoon of the 17th of April, 1862, and opened fire at once upon Fort Jackson, where my headquarters were established. The practice was excellent from the commencement of the fire to the end, and continued without intermission until the morning of the 24th of April, when the fleet passed at about 4 o’clock. Nearly every shell of the many thousand fired at the fort lodged inside of the works. On the first night of the attack the citadel and all buildings in rear of the fort were fired by bursting shell, and also the sand-bag walls that had been thrown around the magazine doors. The fire, as you are aware, raged with great fury, and no effort of ours could subdue it. At this time, and nearly all this night, Fort Jackson was helpless; its magazines were inaccessible, and we could have offered no resistance to a passing fleet. The next morning a terrible scene of destruction presented itself. The wood-work of the citadel being all destroyed, and the crumbling walls being knocked about the fort by the bursting shells, made matters still worse for the garrison. The work of destruction from now until the morning of the 24th, when the fleet passed, was incessant. “ I was obliged to confine the men most rigidly to the casemates, or we should have lost the best part of the garrison. A shell, striking the parapet over one of the magazines, the wall of which was seven feet thick, penetrated five feet and failed to burst. If that shell had exploded, your work would have ended. Another burst near the magazine door, opening the earth and burying the sentinel and another man five feet in the same grave. The parapets and interior of the fort were completely honeycombed, and the large number of sand-bags with which we were supplied alone saved us from being blown to pieces a hundred times, our magazine doors being much exposed. “ On the morning of the 24th, when the fleet passed, the FARRAGUT’S FLAG-SHIP THE “HARTFORD.’
