The armies of Generals McClellan and Pope had now been brought back to the point from which they set out on the campaign of the spring and summer. The object of those campaigns had been frustrated, and the designs of the enemy on the coast of North Carolina and in western Virginia thwarted by the withdrawal of the main body of his forces from these regions. Northeastern Virginia was freed from the presence of Federal soldiers up to the intrenchments of Washington, and soon after the arrival of the army at Leesburg, information was received that the troops that had occupied Winchester had retired to Harper's Ferry and Martinsburg. The war was thus transferred from the interior to the frontier, and the supplies of rich and productive districts made accessible to our army.
To prolong a state of affairs in every way desirable, and not to permit the season of active operations to pass without endeavoring to inflict further injury upon the enemy, the best course appeared to be to transfer the army into Maryland. Although not properly equipped for invasion, lacking much of the material of war, and feeble in transportation, the troops poorly provided with clothing, and thousands of them destitute of shoes, it was yet believed to be strong enough to detain the enemy upon the northern frontier until the approach of winter should render his advance into Virginia difficult, if not impracticable. The condition of Maryland encouraged the belief that the presence of our army, however inferior to that of the enemy, would induce the Washington government to retain all its available force to provide against contingencies which its course toward the people of that State gave it reason to apprehend. At the same time it was hoped that military success might afford us an opportunity to aid the citizens of Maryland in any efforts they might be disposed to make to recover their liberties. The difficulties that surrounded them were fully appreciated, and we expected to derive more assistance in the attainment of our object from the just fears of the Washington government than from any active demonstration on the part of the people, unless success should enable us to give them assurance of continued protection.
The South Carolina commands with Lee in Maryland, were the brigades of N. G. Evans, Kershaw and Jenkins under Col. Joseph Walker; the Fifteenth regiment, Colonel De Saussure, in Drayton's brigade; the Hampton legion infantry, in Wofford's brigade, and Bachman's, Garden's, Rhett's and Boyce's batteries—all with Longstreet's corps; in Jackson's corps, the brigade of Maxcy Gregg and McIntosh's battery; and with the cavalry under Stuart, the Second cavalry, Col. M. C. Butler, of Hampton's brigade, and Hart's battery. Thus it will be seen that four brigades, a regiment and a battalion of infantry, six light batteries, and one regiment of cavalry represented South Carolina in the short and bloody campaign through which we are now to trace their career. We may not do more than make such general allusions to other commands as will put the positions and movements of the South Carolinians in their true moral and military aspect. The gallant comrades of other States, who fought by their side, and on whose heroic daring and sublime fortitude so much depended—whenever they touched their Carolina brethren in battle, their touch was an inspiration, and wherever they fought by their side, their battle was an assurance of strength.
When General Lee took post at Frederick, his position warranted the expectation that the Federal forces in the valley of Virginia and at Harper's Ferry would retreat upon Washington, and he made dispositions to intercept them. In this he was disappointed. Martinsburg and Harper's Ferry were held fast, and Lee resolved to attack those points at once. He prepared an order detailing his combinations and directing the march of each corps and division, and the action of his cavalry. A copy of this, sent Gen. D. H. Hill, fell into General McClellan's hands, as a former order, issued on the Rapidan, had gone into the hands of Pope. Thus McClellan was informed that Lee's army would leave Frederick and cross the mountains at Boonsboro gap; that D. H. Hill's division was to halt at Boonsboro, while the rest of Longstreet's corps marched toward Hagerstown; that Jackson would cross the Potomac and move on Harper's Ferry; that McLaws' division, following Jackson, would enter Pleasant valley and possess Maryland heights, and that Walker's division, following McLaws, would cross the Potomac and possess Loudoun heights. Friday, September 12th, was to be the day when these combinations should result in the capture of Harper's Ferry. That accomplished, Jackson, McLaws and Walker were to rejoin the army at Boonsboro or Hagerstown.
McClellan, thoroughly appreciating the situation, promptly advanced against Boonsboro gap. In this forward movement he was delayed by General Hampton, who skirmished at every available point. As the advance guard approached Frederick with cavalry, infantry and artillery, Hampton drew in his outposts and formed his brigade for attack. The enemy posted a gun, supported by infantry, so as to command the city, and this gave Hampton his opportunity. As the gun opened he ordered Butler to charge, with the brigade in support. One brilliant dash at the gun and its support, and it was in Hampton's possession, the enemy scattered, many killed and wounded, and Colonel Moore, Twenty-eighth Ohio, and 10 other prisoners taken. In this affair, Lieutenant-Colonel Meighan, of the Second South Carolina cavalry, and Captain Waring, of the Jeff Davis legion, acted with distinguished gallantry, and the Second, under its gallant colonel, was commended for its conduct. So successful was the repulse of the advance guard of the enemy that Hampton withdrew at a walk, and camped for the night at Middletown, taking with him the prisoners, and leaving Lieutenant-Colonel Martin, commanding the Jeff Davis legion, to cover his camp.
At daylight, Martin was attacked in the gap of Catoctin mountain which he was holding. Hampton sent up a section of Hart's battery to his support, and Martin held his position against odds until 2 p. m., the fire of Hart's guns driving the opposing artillery from several positions. Then the enemy, reinforced, gained a strong point for artillery, and Hampton withdrew Martin, and in front of Middletown formed for battle, which was soon joined. Hart's guns replied vigorously to those of the Federals, the sharpshooters became warmly engaged, and soon the whole brigade was in action, the fight being pressed by infantry on the enemy's side. Notified that Gen. D. H. Hill had taken position in Boonsboro gap, General Stuart, who had come forward, ordered Hampton to withdraw to the south, and sent Martin with Hart's guns through the gap in South mountain to Boonsboro. Hampton retired to Burkittsville, and on his way encountered a Federal cavalry command, which he charged with Colonel Young's Georgians, dispersed the force, with a loss of 30 killed and wounded on the enemy's part, and 4 killed and 9 wounded in the Cobb legion.
Hill's division, which had marched into Boonsboro gap, was composed of the brigades of Ripley, Rodes, Garland, Colquitt and Anderson. With these commands and Rosser's Fifth Virginia cavalry, Hill stood against the assaults of McClellan for five hours. Longstreet hurried back from Hagerstown to his support and arrived between 3 and 4 p. m. With Longstreet were the South Carolina brigades of Evans and Jenkins, the Fifteenth South Carolina with Drayton, and the Hampton legion with Wofford. Evans' brigade, under Col. P. F. Stevens, was marched to the left of General Hill's battle to support Rodes, who was nearly overwhelmed. Stevens put in the brigade on the right of Rodes, and was at once assailed. The Seventeenth, under Col. F. W. McMaster, held its ground on the right of the brigade, supported by the Holcombe legion, but the pressure of the attack pressed back the Twenty-second and Twenty-third until these regiments, rallied by their gallant commanders, Lieut.-Col. T. C. Watkins and Capt. S. A. Durham and Maj. M. Hilton, returned to the battle, and supported by the Eighteenth, Col. W. H. Wallace, held the battle, in line with the Seventeenth and the legion. But not for long; the enemy crowded up the mountain in such strength that Rodes and Stevens could not hold their line and were driven from the crest.
In this brief struggle, Lieut.-Col. Thomas C. Watkins fell in the thick of the fight, rallying his regiment. His fall was a loss to his command and to his country, but he died as he wished to die, fighting for the independence of the Southern Confederacy. He was succeeded by Major Hilton, who rallied the regiment and restored its position on the crest. In the same contest Lieut.-Col. R. S. Means, of the Seventeenth, was severely wounded. At the moment of his fall the crest was carried, and Colonel McMaster ordered him borne from the field, but he generously refused the aid of his comrades, seeing they must inevitably be captured.
Colonel Stevens especially commended the conduct of Colonel McMaster, Major Hilton, Captain Durham and Adjt. W. P. DuBose. The latter officer was captured after night while endeavoring with a small force to reconnoiter the enemy's front. The loss in the brigade was comparatively small: Seventeenth, killed 7, wounded 37, missing 17; Twenty-second, killed 10, wounded 57, missing 4; Twenty-third, killed 4, wounded 16, missing 4; no reports for the Eighteenth and the legion.
The rapid march of Longstreet from Hagerstown on the 14th had thinned the ranks of all his brigades. Men overcome with fatigue fell by the way in large numbers, and the rush up the mountain in the afternoon almost depleted some commands. Colonel McMaster, reporting the strength of the Seventeenth in the battle, said: "In this battle we had engaged 10 officers and 131 men, rank and file, and ambulance corps." General Longstreet, referring in his recent book to the effect upon the troops of the march from Hagerstown, and the marches and countermarches on the mountain, says:
It was near night when the brigades under Generals Kemper and Garnett and Colonel Walker (Jenkins') returned from their march down the mountain and reached the top. They were put in as they arrived, to try to cover the right of Rodes and Evans, and fill the intervening space to the turnpike. As they marched, the men dropped along the road as rapidly as if under severe skirmish. So manifest was it that nature was exhausted that no one urged them to get up and try to keep their ranks.... The Union brigades were stronger than the Confederates, mine having lost more than half this number by the wayside from exhaustion, under the forced march.
