On the morning of the 7th the order of battle was formed. The bar was ten miles out from the entrance, and careful soundings had been made by two gunboats, under the fire of three Confederate vessels that ran out from the harbor. The main column consisted of ten vessels, led by the flag-ship _Wabash_, and was ordered to attack Fort Walker. Another column of four vessels was ordered to fire upon Fort Beauregard, pass in, and attack the Confederate craft. All were under way soon after breakfast, and were favored by a tranquil sea. The main column, a ship's length apart, steamed in steadily at the rate of six miles an hour, passing Fort Walker at a distance of eight hundred yards, and delivering a fire of shells and rifled shot. Every gun in the fort that could be brought to bear was worked as rapidly as possible, in a gallant defence. After the line had passed the fort, it turned and steamed out again, passing this time within six hundred yards, and delivering fire from the guns on the other side of the vessels. Three times they thus went around in a long ellipse, each time keeping the fort under fire for about twenty minutes. Then the _Bienville_, which had the heaviest guns, and was commanded by Captain Steadman, a South Carolinian, sailed in closer yet, and delivered a fire that dismounted several guns and wrought dreadful havoc. Meanwhile two or three gunboats had taken a position from which they enfiladed the work, and the flag-ship came to a stand at short range and pounded away steadily. This was more than anything at that stage of the war could endure, and from the mast-head the troops were seen streaming out of the fort and across Hilton Head Island as if in panic. A flag of truce was sent on shore, but there was no one to receive it, and soon after two o'clock the National colors were floating over the fort. The flanking column of vessels had attacked Fort Beauregard; and when the commander of that work saw that Fort Walker was abandoned by its defenders, he also retreated with his force. The Confederate vessels escaped by running up a shallow inlet. The loss in the fleet was eight men killed and twenty-three wounded; that of the Confederates, as reported by their commander, was eleven killed and fifty-two wounded or missing. General Sherman said: "Many bodies were buried in the fort, and twenty or thirty were found half a mile distant." The road across Hilton Head Island to a wharf whence the retreating troops were taken to the mainland was strewn with arms and accoutrements, and two howitzers were abandoned. The surgeon of the fort had been killed by a shell and buried by a falling parapet. The troops were debarked and took possession of both forts, repaired and strengthened the works, formed an intrenched camp, and thus gave the Government a permanent foothold on the soil of South Carolina.
