Meantime General Stevens, with the greatest possible rapidity, was advancing his regiments as fast as reorganized to the farther hedge, the one nearest the fort, where they found cover in the ditch. The sun had cleared away the morning clouds, and now shone bright and clear. It was a beautiful and inspiriting sight to see each regiment move forward across the wide field in well-dressed line with colors flying, unheeding the shell and grape which hurtled past or overhead. Rockwell dashed his guns up to the same line nearly, and in the open field maintained a rapid and steady fire on the fort, only five hundred yards distant. Strahan plied his single gun, and the occasional heavy shells from the gunboats burst over the work with a deeper roar. Sharpshooters, as well as the advanced men who still clung close up to the fort, kept the parapet tolerably clear, but the fort was no whit silenced. The grape fell in frequent showers. Notwithstanding the severe losses the men were not discouraged, but were as determined and confident as before. Stimulated by the volleys and cheers of Williams’s troops, they were ready, nay eager, to be led to the assault the second time. General Stevens sent word to Benham that his whole division was in the advanced position, reformed and ready, and that he would attack again as soon as Williams’s movement produced its effect.
Just as he was about to give the order to advance, the firing on the left slackened and ceased, and Williams’s troops were seen moving back. Benham, as hasty and ill judged in abandoning the field as he was precipitate and obstinate in ordering the assault, had ordered them to retreat. On the left were heard the rebel cheers. In front the fort redoubled its fire.
Soon afterwards General Benham ordered General Stevens to withdraw his column to camp. Wright and Williams had already fallen back. The former is particular to state in his report that “the withdrawal from the field of both columns was ordered by General Benham.” General Stevens withdrew his forces without loss and unopposed. Even the advanced men were all brought off. Lieutenant H.G. Belcher, of the 8th Michigan, took them the order, and, working over singly to the left, they got under cover of the bushes on that side and thus withdrew. The enemy attempted no pursuit, and by ten A.M. the entire force was back in camp.
Thus ended the battle of James Island or Secessionville, the culmination of crass obstinacy and folly. Benham, who, deaf to the orders of his commander, deaf to the warnings of Wright, deaf to Stevens’s earnest entreaties to be allowed to attack later in the day and after due preparation, had so rashly and obstinately forced the fight,—this very Benham shrank from the shock of battle, and ordered the retreat when victory was within his grasp.
The enemy’s forces upon James Island were commanded by General N.G. Evans, and numbered certainly not less than 9000 effective. Colonel T.G. Lamar commanded the fort and was severely wounded. He had two companies, B and I, of his own regiment, the 1st South Carolina artillery, the 1st South Carolina or Charleston and 9th South Carolina or Pee Dee battalions, four officers and one hundred picked men of the 22d South Carolina, and three officers and presumably the crew of the floating battery, which had been withdrawn from the fire of the three-gun battery a few days before. All these commands must have numbered at least 800, although Colonel Lamar reports that his force did not exceed 500 until reinforced. He was soon reinforced by the 4th Louisiana battalion, numbering 250, and later by the balance of the 22d South Carolina, so that he must have had at least 1500 men before the action closed. The losses in these commands amounted to 172, of which the original garrison suffered 144, an unusually heavy loss behind strong works, viz.: Charleston battalion, 42; 1st South Carolina artillery, 55; Pee Dee battalion, 29; detachment 22d South Carolina, 18; total, 144. The loss of the 1st South Carolina artillery, 55, would indicate that more than two companies were in the fort.
Colonel Lamar reports that he was expecting an attack, having a detachment at each gun, and the alarm was given when the pickets were driven in; yet the assaulting column advanced so rapidly that it was within seven hundred yards when he reached the battery, and much nearer when in person he fired the 8-inch columbiad heavily charged with grape, which he says broke the leading regiment, cutting it completely in two.
The other Confederate troops engaged were the 1st, 24th, and 25th South Carolina, Boyce’s field battery, and Company H, 1st South Carolina artillery, which manned the Reed battery. General Evans ordered up the 47th and 51st Georgia to support his right. His force, engaged and on the field, numbered 4500 effective, besides which were plenty of other troops available on the main works.
The Confederate loss all told was 204.
The Union loss aggregated 685, of which Stevens’s column suffered 529; Williams’s brigade, 152; Wright’s division, four.
The 8th Michigan lost 185 out of 534, or thirty per cent.; 13 out of 22 officers who went into the fight, including every officer of the storming party, were killed or wounded. The Highlanders lost 110 out of 484, notwithstanding which they withdrew in good order, and brought off 60 of their wounded, some of their dead, and their two prisoners. These losses would have been much greater had it not been for the partial shelter afforded by the cotton-ridges, and the fire of the men behind them, which kept down that of the fort. But the loss of the garrison is unparalleled behind such works, and shows the desperate nature of the fighting.
