On the other side of the harbor, directly opposite Fort Sumter, is one of the strongest sides of Fort Moultrie. During the last three months it has been strengthened by every appliance that military art could suggest. Its marlons, moats, glaces, and embrasures are perfectly protected. The weak walls of the fort were made perfectly secure for the gunners while at work. From this point throughout the engagement vast numbers of shot and heavy balls were discharged.

Behind this, and near Sullivan’s Island, the Floating Battery was stationed, with two sixty-four and two forty-two pounders. Its sides of iron and palmetto logs were impenetrable. Every shot from it told on Fort Sumter, and the men in charge of it were so secure in their position, that some of them indulged in soldiers’ pastimes, while others played five cent ante, euchre and bluff.

The Mortar Battery at Mount Pleasant was five hundred yards from the Floating Battery, and was mounted with two mortars within excellent range of Fort Sumter. The shells from this mortar were thrown with great precision. You now have all the positions of the works bearing directly on Fort Sumter.

All through Friday morning the greatest activity at all points was displayed. Three times Major Anderson’s barracks were set on fire, and twice he succeeded in putting out the flames, and to do this it was necessary to employ all his force in passing along water. To get water it was necessary for some of his men to go outside the walls, and hand the buckets in through the port-holes, during all which time they were exposed to a most terrific fire from the various batteries.

This last expedient was not resorted to until the fort was on fire for the third time, and the flames had increased to an alarming pitch. Meantime, Major Anderson’s guns were silent. He allowed his men to be exposed to the galling fire upon them but for a few moments, and then ordered them in and shut the batteries as the smoke was too thick to work them. At noon the flames burst from every quarter of Fort Sumter, and its destruction appeared inevitable.

NAVAL EXPEDITION FOR THE RELIEF OF SUMTER.

The Government had sent a well-laden fleet to the relief of Fort Sumter, a portion of which arrived in Charleston harbor time enough to witness the bombardment of the fort, without the power to help its heroic garrison.

This fleet left New York and Washington from the 6th to the 9th of April. It consisted of the sloop-of-war, Pawnee, 10 guns, and 200 men; Pocahontas, 5 guns, 110 men; cutter Harriet Lane, 5 guns, 110 men; accompanied by the transport Baltic, and the steam-tugs Yankee and Uncle Ben, with additional men and stores. Owing to stormy weather, the vessels were unable to reach the Charleston coast at the appointed time. The Pawnee, Harriet Lane, and the Baltic arrived at the rendezvous on the morning of the 12th April, but the Pocahontas did not join them until the next day. The steamtug Yankee lost her smoke-stack in the storm which dispersed the fleet, and did not reach the neighborhood of Charleston till after the departure of her consorts, and eventually returned to New York. Nothing was heard of the Uncle Ben until the 30th of April, when intelligence was received that she had been captured by the insurgents off the coast of North Carolina.

The orders of the expedition were, that unarmed boats should first be sent to the fort with stores only; but if these were fired upon, every effort was to be made to relieve the fort by stratagem or force. The vessels of war and the Baltic proved of too heavy draft for any hopes of passing the bar, and the steam-tugs which were to have been sent in with supplies, failed to make their appearance. The attack on the fort, before any measures of a peaceable character could be adopted for its relief, left no alternative but force, to the commandant of the fleet, if the object of his expedition was to be accomplished. A consultation of officers was held at four o’clock on the afternoon of the 12th, and the following plan was agreed upon: the Pawnee and the Harriet Lane were to remain at anchor during the night; at dawn, on the 13th, the Pawnee was to hoist out her armed launches, and the Baltic was to put her boats alongside, freighted with the provisions and troops designed for the fort. The war vessels were then to tow the boats as far as possible on their perilous journey, when they were to be cast off, and allowed to pursue their course toward the fort, relying upon the guns of the men-of-war, and what aid might be extended from Sumter, to protect them from the batteries and flotilla of armed boats, which were in readiness to dispute their advance. During the night the Baltic went aground on Rattlesnake Shoals, and the plan agreed upon was, from necessity, relinquished. The conflagration of the barracks of the fort having precipitated its evacuation earlier than was anticipated, the officers of the fleet abandoned other plans for its relief.

At two o’clock on the 14th of April, Major Anderson and the garrison of Fort Sumter were received on board the Baltic, and the fleet shortly after sailed for New York. The flag of the fort was borne at the mast-head of the Baltic as she entered the bay of New York, where it was saluted by guns from every fort in the harbor, and hailed by the shouts of more than a hundred thousand people, who lined the wharves of the city. It was also raised over the equestrian statue of Washington in Union Square, in that city, when the great Union meeting was held on the afternoon of Saturday, April 20.
