The President added,—

Elsewhere General McClellan has written of the 12th:

His army was organized: Right wing, under General Burnside: First and Ninth Corps; the Kanawha Division, under General J. D. Cox, was assigned with the Ninth Corps about the 8th instant.

Centre column: Second and Twelfth Corps, under General Sumner.

Left wing: Sixth Corps and Couch’s division of the Fourth under General Franklin; Sykes’s division, Fifth Corps, independent.[58]

Besides the despatches of the 11th and 12th, his cavalry under General Pleasonton, which was vigilant and pushing, sent frequent reports of his steady progress. In the afternoon Pleasonton and the Ninth Corps under General Reno entered Fredericktown. This advance, by the National road, threatened to cut off two of Stuart’s cavalry regiments left at the Monocacy Bridge. To detain the enemy till these were withdrawn, the outpost on that road was reinforced. Hampton retired his cavalry beyond Frederick and posted his artillery to cover the line of march, where he was soon attacked by a formidable force. To make safe the retreat of the brigade, a cavalry charge was ordered, under Colonel Butler, Lieutenant Meaghan’s squadron leading. Colonel Moore, of the Twenty-eighth Ohio Cavalry, and a number of other prisoners were captured. This so detained the enemy as to give safe withdrawal for the brigade to Middletown, leaving Lieutenant-Colonel Martin’s cavalry and two guns on guard at the gap of the Catoctin range of mountains.

Before withdrawing from Frederick on the 12th, General Stuart sent orders for the brigade under General Fitzhugh Lee to move around the right of the Union army and ascertain the meaning and strength of its march.

Following his orders of the 12th, General Pleasonton detached a cavalry brigade on the 13th and section of artillery under Colonel McReynolds to follow Fitzhugh Lee, and Rush’s Lancers were sent to Jefferson for General Franklin’s column. With his main force he pursued the Confederates towards Turner’s Pass of South Mountain. Midway between Frederick and South Mountain, running parallel, is a lesser range, Catoctin, where he encountered Stuart’s rear-guard. After a severe affair he secured the pass, moved on, and encountered a second force near Middletown. Reinforced by Gibson’s battery, he attacked and forced the way to a third stand. This in turn was forced back and into the mountain at Turner’s Pass.

On that day McClellan’s columns marched: Ninth Corps, to and near Middletown, eight miles; First Corps, to the Monocacy, eight miles; Twelfth Corps, to Frederick, nine miles; Second Corps, to Frederick, eight miles; Sixth Corps, to Buckeystown, seven miles; Couch’s division, to Licksville, six miles; Sykes’s division, to Frederick, eight miles.

At Frederick, General Lee’s special order No. 191 was handed to General McClellan at his head-quarters with his centre (Sumner’s) column.

How lost and how found we shall presently see, and see that by the mischance and accident the Federal commander came in possession of information that gave a spur, and great advantage, to his somewhat demoralized army.

CHAPTER XVI.

Before this tell-tale slip of paper found its way to McClellan’s head-quarters he was well advised by his cavalry, and by despatches wired him from east and west, of the movements of Lee’s army, and later, on that eventful 13th day of September, he received more valuable information, even to a complete revelation of his adversary’s plans and purpose, such as no other commander, in the history of war, has had at a time so momentous. So well satisfied was he that he was master of the military zodiac that he despatched the Washington authorities of Lee’s “gross mistake” and exposure to severe penalties. There was not a point upon which he wanted further information nor a plea for a moment of delay. His army was moving rapidly; all that he wished for was that the plans of the enemy would not be changed. The only change that occurred in the plans was the delay of their execution, which worked to his greater advantage. By following the operations of the armies through the complications of the campaign we may form better judgment of the work of the commanders in finding ways through its intricacies: of the efforts of one to grasp the envied crown so haplessly tendered; of the other in seeking refuge that might cover catastrophe involved in the complexity of misconceived plans.

The copy of the order that was lost was sent by General Jackson to General D. H. Hill under the impression that Hill’s division was part of his command, but the division had not been so assigned, and that copy of the order was not delivered at Hill’s head-quarters, but had been put to other use. The order sent to General Hill from general head-quarters was carefully preserved.

When the Federals marched into Frederick, just left by the Confederates, General Sumner’s column went into camp about noon, and it was then that the despatch was found by Colonel Silas Colgrove, who took it to division head-quarters, whence it was quickly sent to the Federal commander.

General McClellan reported to General Halleck that the lost order had been handed him in the evening, but it is evident that he had it at the time of his noonday despatch to the President, from his reference to the facts it exposed.

It is possible that it was at first suspected as a ruse de guerre, and that a little time was necessary to convince McClellan of its genuineness, which may account for the difference between the hinted information in his despatch to General Halleck and the confident statement made at noonday to the President.

Some of the Confederates were a little surprised that a matter of such magnitude was intrusted to pen-and-ink despatches. The copy sent me was carefully read, then used as some persons use a little cut of tobacco, to be assured that others could not have the benefit of its contents.

It has been in evidence that the copy that was lost had been used as a wrapper for three fragrant Confederate cigars in the interim between its importance when issued by the Confederate chief and its greater importance when found by the Federals.

General Halleck thought the capital in imminent peril before he heard from McClellan on the 13th, as shown on that day by a despatch to General McClellan:

But later, the “lost despatch” having turned up at head-quarters of General McClellan, that commander apprised the authorities of the true condition of affairs in the following:

With the knowledge afforded by securing Lee’s “lost order” the passes of the South Mountain became important points. If he could force them, McClellan might fall on the divided columns of the Confederates and reach Harper’s Ferry in time to save its garrison; but Lee received intelligence of his only moderate forward movement, and, without knowing then how it came to be made, recalled a force to make resistance, and, so supplementing or complementing by his rapid moves the Federal commander’s slowness, saved his campaign from the disastrous failure that threatened it.

General McClellan claimed to have been more vigorous in pursuit after he received the “lost despatch,” but events do not support the claim. He had time after the despatch was handed him to march his army to the foot of South Mountain before night, but gave no orders, except his letter to General Franklin calling for vigorous action, which was afterwards tempered by caution to wait for developments at Turner’s Pass. He gave no intimation of the despatch to his cavalry leader, who should have been the first to be advised of the points in his possession. General Pleasonton had pushed the Confederate cavalry back into the mountains long before night of the 13th under his instructions of the 12th. Had he been informed of the points known by his chief in the afternoon, he would have occupied South Mountain at Turner’s Pass before any of the Confederate infantry was there or apprised of his approach. General McClellan’s orders for the 14th were dated,—

He wrote General Franklin at 6.20 P.M., giving the substance of information of the despatch, but not mentioning when or how he came by it, and ordered him to march for the mountain pass at Crampton’s Gap, to seize the pass if it was not strongly guarded, and march for Rohrersville, to cut off the command under McLaws about Maryland Heights, capture it, and relieve the garrison at Harper’s Ferry, and return to co-operate in capturing the balance of the Confederate army north of the Potomac; but, in case the gap was occupied by a strong force, to await operations against it until he heard the engagement of the army moving upon Turner’s Pass. He wrote General Franklin that General Pleasonton had cleared the field east of the mountain of Confederate cavalry. After relieving Harper’s Ferry, Franklin was to destroy bridges and guard against crossing of the Confederates to the north side, his idea being to cut the Confederate army in two and capture or break it up in detail. His appeal was urgent for the best work that a general could exercise. The division under General Couch was ordered to General Franklin, without waiting for all of its forces to join. This is the only order of the records that indicates unusual action on the part of the Union commander, and General Franklin’s evidence before the Committee on the Conduct of the War shows that his orders of the 13th were so modified on the 14th as to direct his wait for Couch’s division to join him, and the division joined him after nightfall.

The divisions of the Ninth Corps reached Middletown on the 13th, under the orders of the 12th, issued before the lost despatch was found, one of them supporting Pleasonton’s cavalry; but Rodman’s, under misconception of orders, marched back towards Frederick.

South Mountain range, standing between the armies, courses across Maryland northeast and southwest. Its average height is one thousand feet; its rugged passes give it strong military features. The pass at Turner drops off about four hundred feet. About a mile south of this the old Sharpsburg road crosses at a greater elevation through rugged windings; a fork of this road, on the mountain-side, makes a second way over below Fox’s Pass, while another turns to the right and leads back into the turnpike at the summit, or Mountain House.

On the north side of the turnpike a road leads off to the right, called the old Hagerstown road, which winds its course through a valley between a spur and the mountain, and courses back to the turnpike along the top. A more rugged route than this opens a way to the mountain-top by a route nearer the pike.

General Pleasonton, not advised of the lost despatch, did not push for a careful reconnoissance on the 13th. At the same time, General Stuart, forced back into the mountains, finding his cavalry unserviceable, advised General D. H. Hill of severe pressure, called for a brigade of infantry, ordered Hampton’s cavalry down to Crampton’s Pass to assist Robertson’s brigade, Colonel Munford commanding, leaving the Jeff Davis Legion, under Colonel Martin, Colonel Rosser with another cavalry detachment, and Stuart’s horse artillery to occupy the passes by the old Sharpsburg road. Colquitt’s brigade of infantry reported to him under his call. After posting it near the east base of the mountain to hold the pass, he rode to join his other cavalry detachments down at Crampton’s Pass. He only knew of two brigades of infantry pressing him back, and so reported. His cavalry, ordered around the Union right under General Fitzhugh Lee, for information of the force in his front, had failed to make report. General Hill ordered two brigades, Garland’s and Colquitt’s, into the pass to report to Stuart, and drew his other three near the foot of the mountain. Garland’s brigade filed to the right after ascending the mountain, and halted near the turnpike. Colquitt’s brigade took its position across the turnpike and down towards the base of the mountain, Lane’s batteries at the summit.

It seems that up to the night of the 13th most of the Confederates were looking with confidence to the surrender at Harper’s Ferry on the 13th, to be promptly followed by a move farther west, not thinking it possible that a great struggle at and along the range of South Mountain was impending; that even on the 14th our cavalry leader thought to continue his retrograde that day. General Hill’s attention was given more to his instructions to prevent the escape of fugitives from Harper’s Ferry than to trouble along his front, as the instructions covered more especially that duty, while information from the cavalry gave no indication of serious trouble from the front.

A little after dark of the 13th, General Lee received, through a scout, information of the advance of the Union forces to the foot of South Mountain in solid ranks. Later information confirmed this report, giving the estimated strength at ninety thousand. General Lee still held to the thought that he had ample time. He sent for me, and I found him over his map. He told of the reports, and asked my views. I thought it too late to march on the 14th and properly man the pass at Turner’s, and expressed preference for concentrating D. H. Hill’s and my own force behind the Antietam at Sharpsburg, where we could get together in season to make a strong defensive fight, and at the same time check McClellan’s march towards Harper’s Ferry, in case he thought to relieve the beleaguered garrison by that route, forcing him to first remove the obstacle on his flank. He preferred to make the stand at Turner’s Pass, and ordered the troops to march next morning, ordering a brigade left at Hagerstown to guard the trains. No warning was sent McLaws to prepare to defend his rear, either by the commanding general or by the chief of cavalry. The hallucination that McClellan was not capable of serious work seemed to pervade our army, even to this moment of dreadful threatening.

After retiring to my couch, reflecting upon affairs, my mind was so disturbed that I could not rest. As I studied, the perils seemed to grow, till at last I made a light and wrote to tell General Lee of my troubled thoughts, and appealed again for immediate concentration at Sharpsburg. To this no answer came, but it relieved my mind and gave me some rest.

At daylight in the morning the column marched (eight brigades with the artillery), leaving Toombs’s brigade. A regiment of G. T. Anderson’s that had been on guard all night was not relieved in time to join the march, and remained with Toombs. The day was hot and the roads dry and beaten into impalpable powder, that rose in clouds of dust from under our feet as we marched.

Before sunrise of the 14th, General Hill rode to the top of the mountain to view the front to which his brigade had been called the day before. As he rode he received a message from General Stuart, informing him that he had sent his main cavalry force to Crampton’s Pass, and was then en route to join it. He found Garland’s brigade at the summit, near the Mountain House, on the right of the road, and Colquitt’s well advanced down the east side. He withdrew the latter to the summit, and posted two regiments on the north side of the pike behind stone walls, the others on the south side under cover of a woodland. Upon learning of the approaches to his position, he ordered the brigade under G. B. Anderson and one of Ripley’s regiments up, leaving Rodes’s brigade and the balance of Ripley’s to watch for refugees from Harper’s Ferry.

While he was withdrawing and posting Colquitt’s brigade, General Pleasonton was marching by the road three-fourths of a mile south, feeling his way towards Fox’s Gap, with the brigade of infantry under Colonel Scammon. Co-operating with this advance, Pleasonton used his cavalry along the turnpike. His batteries were put in action near the foot of the mountain, except one section of McMullen’s under Lieutenant Crome, which advanced with the infantry. The battle was thus opened by General Pleasonton and General Cox without orders, and without information of the lost despatch. The latter had the foresight to support this move with his brigade under Colonel Crook. Batteries of twenty-pound Parrott guns were posted near the foot of the mountain in fine position to open upon the Confederates at the summit.

After posting Colquitt’s brigade, General Hill rode off to his right to examine the approach to Fox’s Gap, near the point held by Rosser’s cavalry and horse artillery. As he passed near the gap he heard noise of troops working their way towards him, and soon artillery opened fire across the gap over his head. He hurried back and sent Garland’s brigade, with Bondurant’s battery, to meet the approaching enemy. Garland made connection with Rosser’s detachment and engaged in severe skirmish, arresting the progress of Scammon’s brigade till the coming of Crook’s, when Cox gave new force to his fight, and after a severe contest, in which Garland fell, the division advanced in a gallant charge, which broke the ranks of the brigade, discomfited by the loss of its gallant leader, part of it breaking in confusion down the mountain, the left withdrawing towards the turnpike. G. B. Anderson’s brigade was in time to check this success and hold for reinforcements. Ripley’s brigade, called up later, came, but passed to the right and beyond the fight. General Hill had posted two batteries on the summit north of the turnpike, which had a destructive cross fire on Cox as he made his fight, and part of Colquitt’s right regiments were put in, in aid of G. B. Anderson’s men. About two P.M., General Cox was reinforced by the division under General Wilcox, and a little after three o’clock by Sturgis’s division, the corps commander, General Reno, taking command with his last division under Rodman.

As Sturgis’s division came into the fight, the head of my column reached the top of the pass, where the brigades of G. T. Anderson and Drayton, under General D. R. Jones, filed to the right to meet the battle, and soon after General Hood with two brigades. The last reinforcement braced the Confederate fight to a successful stand, and held it till after night in hot contest, in which many brave soldiers and valuable officers were lost on both sides.

The fight was between eight brigades on the Union side, with a detachment of cavalry and superior artillery attachments, against two of D. H. Hill’s and four of my brigades, with Rosser’s detachment of cavalry and artillery. Ripley’s brigade of Hill’s division marched for the fight, but lost its direction and failed to engage. The Confederate batteries made handsome combat, but were of inferior metal and munitions. Numerically, the Union brigades were stronger than the Confederates, mine having lost more than half its numbers by the wayside, from exhaustion under its forced march. It seems that several brigades failed to connect closely with the action. Ripley’s, on the Confederate side, General Hill said, “didn’t pull a trigger.” G. T. Anderson claimed that some of his skirmishers pulled a few triggers, while Harland’s Union brigade of Rodman’s division seems to have had little use for its guns. Lieutenant Crome brought a section of McMullen’s battery up in close connection with Cox’s advance, put it in, and held it in gallant action till his gunners were reduced to the minimum of working force, when he took the place of cannoneer and fought till mortally wounded.

On the Union side the officers had their time to organize and place their battle, and showed skill in their work. The Confederates had to meet the battle, as it was called, after its opening, on Rosser’s detachment. The lamented Garland, equal to any emergency, was quick enough to get his fine brigade in, and made excellent battle, till his men, discouraged by the loss of their chief, were overcome by the gallant assault under Cox. General Reno, on the Union side, an officer of high character and attainments, was killed about seven o’clock P.M. Among the Union wounded was Colonel Rutherford B. Hayes; afterwards President of the United States.

The pass by the lower trail, old Sharpsburg road, was opened by this fight, but the Confederates standing so close upon it made it necessary that they should be dislodged before it could be utilized.

The First Corps marched from the Monocacy at daylight and approached the mountain at one P.M. General Hooker had three divisions, under Generals Hatch, Ricketts, and Meade. General Hatch had four brigades, Generals Ricketts and Meade three each, with full artillery appointments. At two o’clock, General Hooker was ordered north of the turnpike to make a diversion in favor of the troops operating on the south side under General Reno. Meade’s division was marched, followed by Hatch’s and Ricketts’s,—Meade’s on the right, Hatch on Meade’s left, Ricketts in reserve. Meade’s division was deployed along the foot-hills. A cavalry regiment under Colonel Williams, First Massachusetts, was sent to the far right in observation. Meade’s advance was followed by Hatch and Ricketts.

General Hill’s only available force to meet this formidable move was his brigade under General Rodes. He ordered Rodes to his left to a prominent position about a mile off which commanded that part of the field. Cutts’s battalion of artillery had been posted on the left of the turnpike, to cover by its fire the route just assigned for Hooker’s march. The weight of the attack fell upon Rodes’s brigade, and was handsomely received. Evans’s brigade, fortunately, came up, and was sent to General Hill, who ordered it out to connect with Rodes’s right. Before making close connection it became engaged, and operated near Rodes’s right, connecting with his fight and dropping back as the troops on his left were gradually forced from point to point.

As the brigades under Generals Kemper, Garnett, and Colonel Walker (Jenkins’s brigade) approached the mountain, a report reached general head-quarters that the enemy was forcing his way down the mountain by the old Sharpsburg road. To meet this General Lee ordered those brigades to the right, and they marched a mile and more down a rugged way along the base of the mountain before the report was found to be erroneous, when the brigades were ordered back to make their way to the pike and to the top of the mountain in double time. General Rodes had five regiments, one of which he left to partially cover the wide opening between his position and the turnpike. In view of the great force approaching to attack him his fight seemed almost hopeless, but he handled his troops with skill, and delayed the enemy, with the little help that finally came, till night, breaking from time to time as he was forced nearer our centre at the turnpike.

Gibbon’s brigade had been called from Hooker’s corps, and was ordered up the mountain by the direct route as the corps engaged in its fight farther off on the right.

A spur of the mountain trends towards the east, opening a valley between it and the mountain. Through this valley and over the rising ground Meade’s division advanced and made successful attack as he encountered the Confederates. Cooper’s battery marched, and assisted in the several attacks as they were pushed up the mountain slope. The ground was very rough, and the Confederates worked hard to make it too rough, but the divisions, with their strong lines of skirmishers, made progress. Rodes made an effort to turn the right of the advancing divisions, but Hooker put out a brigade from Hatch’s division, which pushed off the feeble effort, and Rodes lost his first position.

It was near night when the brigades under Generals Kemper and Garnett and Colonel Walker returned from their march down the foot of 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. As the brigades were led to places along the line, the divisions of Hatch and Ricketts were advancing; the former, in range, caught the brigades under fire before their lines were formed. At the same time Meade’s division was forcing Rodes and Evans from their positions, back towards the turnpike.

General McClellan claimed fifteen hundred prisoners taken by his troops, and that our loss in killed and wounded was greater than his own, which was fifteen hundred. He estimated the forces as about equal, thirty thousand each. General D. H. Hill does not admit that the Confederates had more than nine thousand.

Several efforts have been made to correctly report the numerical strength of my column, some erroneously including the brigades detached with R. H. Anderson’s, and others the brigade of General Toombs and the regiment of G. T. Anderson’s brigade, that were left at Hagerstown. General Hill concedes reluctantly that four thousand of my men came to his support in detachments, but does not know how to estimate the loss. Considering the severe forced march, the five brigades that made direct ascent of the mountain were in good order. The three that marched south of the turnpike, along a narrow mountain trail part of the way, through woodlands and over boulders, returning, then up the mountain, the last march at double time, were thinned to skeletons of three or four hundred men to a brigade when they reached the Mountain House. That they succeeded in covering enough of the position to conceal our retreat after night is sufficient encomium of their valorous spirit.

CHAPTER XVII.

General Fitzhugh Lee’s cavalry was ordered to cover our march, but Pleasonton pushed upon him so severely with part of the Eighth Illinois Cavalry and Tidball’s battery that he was forced off from our line through Boonsborough and found his way to the Potomac off the rear of General Lee’s left, leaving his killed and wounded and losing two pieces of artillery. Otherwise our march was not disturbed. In addition to his regular complement of artillery, General D. H. Hill had the battalion under Lieutenant-Colonel A. S. Cutts. The batteries were assigned positions near the ridge under the crest, where they could best cover the fields on the farther side of the stream. A few minutes after our lines were manned, information came of the capitulation of Harper’s Ferry, and of the withdrawal of the troops to the Virginia side of the Potomac.

General Toombs’s brigade joined us early on the 15th, and was posted over the Burnside Bridge. He was subsequently ordered to detach two regiments, as guard for trains near Williamsport.

As long as the armies were linked to Harper’s Ferry, the heights in front of Sharpsburg offered a formidable defensive line, and in view of possible operations from Harper’s Ferry, through the river pass, east of South Mountain, formed a beautiful point of strategic diversion. But when it transpired that Harper’s Ferry was surrendered and the position was not to be utilized, that the troops there were to join us by a march on the south side, its charms were changed to perplexities. The threatening attitude towards the enemy’s rear vanished, his line of communication was open and free of further care, and his army, relieved of entanglements, was at liberty to cross the Antietam by the upper fords and bridges, and approach from vantage-ground General Lee’s left. At the same time the Federal left was reasonably secured from aggression by cramped and rugged ground along the Confederate right. Thus the altered circumstances changed all of the features of the position in favor of the Federals.

Approaching Crampton’s Gap on the morning of the 14th, Hampton’s cavalry encountered the enemy’s and made a dashing charge, which opened his way to Munford’s, both parties losing valuable officers and men. When General Stuart rode up, he saw nothing seriously threatening, and ordered Hampton south to the river pass; thinking that there might be something more important at that point, he rode himself to Maryland Heights to see General McLaws, and to witness the operations at Harper’s Ferry, posting Colonel Munford with two regiments of cavalry, two regiments of Mahone’s brigade under Colonel Parham, part of the Tenth Georgia Infantry, Chew’s battery of four guns, and a section of navy howitzers, to guard the pass. The infantry regiments were posted behind stone walls at the base of the mountain, the cavalry dismounted on the flanks acting as sharp-shooters.

At noon General Franklin marched through Burkittsville with his leading division under General Slocum, holding the division under General W. F. Smith in reserve. His orders were to wait until Couch’s division joined him, but he judged that the wait might be more favorable to the other side. Slocum deployed his brigades, Bartlett’s, Newton’s, and Torbert’s, from right to left, posted Wolcott’s battery of six guns on his left and rear, and followed the advance of his skirmish line, the right brigade leading. When the Confederate position was well developed, the skirmishers were retired, and the order to assault followed,—the right regiments of Newton’s brigade supporting Bartlett’s assault, the regiments on the left supporting Torbert’s. The Confederates made a bold effort to hold, but the attack was too well organized and too cleverly pushed to leave the matter long in doubt. Their flanks, being severely crowded upon, soon began to drop off, when a sweeping charge of Slocum’s line gained the position. The brigades of General Brooks and Colonel Irwin of General Smith’s division were advanced to Slocum’s left and joined in pursuit, which was so rapid that the Confederates were not able to rally a good line; the entire mountain was abandoned to the Federals, and the pursuit ended. Some four hundred prisoners, seven hundred stand of arms, and one gun were their trophies in this affair. General Franklin’s total loss was five hundred and thirty-three.[61]

General McLaws had ordered General Cobb’s brigade and the other regiments of Mahone’s to reinforce the troops at the gap, but they only came up as the Federals were making their sweeping charge, and were driven back with their discomfited comrades. General Semmes’s brigade at the Brownsville Pass, a mile south, with five or six guns, attempted to relieve their comrades, but the range was too great for effective work. That McLaws was not prepared for the sudden onslaught is evident from the assurances made him by the cavalry commander. His orders for Cobb were severe enough, but Franklin was too prompt to allow Cobb to get to work. Upon hearing the noise of battle, he followed his orders, riding with General Stuart, but the game was played before he could take part in it. Night came and gave him time to organize his forces for the next day. Had the defenders been posted at the crest of the mountain it is probable they could have delayed the assaulting forces until reinforced. But cavalry commanders do not always post artillery and infantry to greatest advantage.

General Cobb made worthy effort to arrest the retreat and reorganize the forces, but was not able to fix a rallying-point till after the pass was lost and the troops were well out of fire of the pursuers. General Semmes came to his aid, with his staff, but could accomplish nothing until he drew two of his regiments from Brownsville Pass and established them with a battery as a rallying-point. General McLaws reformed his line about a mile and a half south of the lost gap, and drew all of his force not necessary to the bombardment at Harper’s Ferry to that line during the night.

Commanding First Division, First Army Corps, Army of Northern Virginia.

Under cover of the night, Lieutenant-Colonel H. Davis, at the head of the Union cavalry, left Harper’s Ferry, crossed the Potomac, marched up the left bank, through Sharpsburg, and made good his escape, capturing some forty or fifty Confederate wagons as they were moving south from Hagerstown.

We left McLaws in possession of Maryland Heights, on the 14th, with his best guns planted against the garrison at Harper’s Ferry. The Potomac River was between his and Jackson’s and Walker’s forces, and the Shenandoah divided Jackson’s and Walker’s commands. Walker posted his division to defend against the escape from Harper’s Ferry, and planted three Parrott guns of Captain French’s battery and two rifle pieces of Captain Branch’s on Loudoun Heights, having effective fire along Bolivar Heights. General Jackson sent word to McLaws and Walker that the batteries were not to open till all were ready, but the latter, hearing the engagement along South Mountain drawing nearer, and becoming impatient lest delay should prove fatal, ordered his guns to open against the batteries along Bolivar Heights, and silenced those under range.

General Jackson ordered A. P. Hill’s division along the left bank of the Shenandoah to turn the enemy’s left, the division under Lawton down the turnpike in support of Hill, and his own division to threaten against the enemy’s right. Hill’s division did its work in good style, securing eligible positions on the enemy’s left and left rear of Bolivar Heights, and planted a number of batteries upon them during the night; and Jackson had some of his best guns passed over the Shenandoah to commanding points near the base of Loudoun Heights. At daylight Lawton’s command moved up close to the enemy. At the same time the batteries of Hill’s division opened fire, and a little later all the batteries, including those of McLaws and Walker. The signal ordered for the storming columns was to be the cessation of artillery fire. In about one hour the enemy’s fire ceased, when Jackson commanded silence upon his side. Pender’s brigade started, when the enemy opened again with his artillery. The batteries of Pegram and Crenshaw dashed forward and renewed rapid fire, when the signal of distress was raised.

Colonel D. H. Miles, the Federal commander at Harper’s Ferry, was mortally wounded, and the actual surrender was made by General White, who gave up eleven thousand prisoners, thirteen thousand small-arms, seventy-two cannon, quantities of quartermaster’s stores and of subsistence.[62]

General Franklin had posted his division under General Couch at Rohrersville on the morning of the 15th, and proceeded to examine McLaws’s line established the night before across Pleasant Valley. He found the Confederates strongly posted covering the valley, their flanks against the mountain-side. Before he could organize for attack the firing at Harper’s Ferry ceased, indicating surrender of that garrison and leaving the troops operating there free to march against him. He prepared, therefore, for that eventuality.

The “lost order” directed the commands of Generals Jackson, McLaws, and Walker, after accomplishing the objects for which they had been detached, to join the main body of the army at Boonsborough or Hagerstown. Under the order and the changed condition of affairs, they were expected, in case of early capitulation at Harper’s Ferry, to march up the Rohrersville-Boonsborough road against McClellan’s left. There were in those columns twenty-six of General Lee’s forty brigades, equipped with a fair apportionment of artillery and cavalry. So it seemed to be possible that Jackson would order McLaws and Walker up the Rohrersville road, and move with his own corps through the river pass east of South Mountain, against McClellan’s rear, as the speedier means of relief to General Lee’s forces. But prudence would have gone with the bolder move of his entire command east of the mountain against McClellan’s rear, with a fair field for strategy and tactics. This move would have disturbed McClellan’s plans on the afternoon of the 15th, while there seemed little hope that McClellan would delay his attack until Jackson could join us, marching by the south side.

The field, and extreme of conditions, were more encouraging of results than was Napoleon’s work at Arcola.

General Jackson judged it better to join us by the south side, marched promptly with two of his divisions (leaving A. P. Hill with six brigades to receive the surrender and captured property), then ordered Walker’s and McLaws’s troops to follow his march. With his report of surrender of the garrison he sent advice of his march by the south side to join us.

At daylight on the 15th the head of General Lee’s column reached the Antietam. General D. H. Hill, in advance, crossed and filed into position to the left of the Boonsborough turnpike, G. B. Anderson on his right, Garland’s brigade under Colonel McRae, Ripley, and Colquitt, Rodes in rear near Sharpsburg, my command on his right. The two brigades under Hood were on my right, Kemper, Drayton, Jenkins (under Colonel Walker), Washington Artillery, on the ridge near the turnpike, and S. D. Lee’s artillery. Pickett’s brigade (under Garnett) was in a second line, G. T. Anderson’s brigade in rear of the battalions, Evans’s brigade on the north side of the turnpike; Toombs’s brigade joined and was posted at bridge No. 3 (Burnside Bridge). As the battalions of artillery attached to the divisions were all that could find places, General Lee sent the reserve artillery under General Pendleton across the Potomac.

As soon as advised of the surrender and Jackson’s march by the south side, my brigades under Hood were moved to the extreme left of the line, taking the division of General D. H. Hill within my limits, while three of S. D. Lee’s batteries were sent in support of Hood’s brigades. The pursuit ordered by General McClellan was the First, Second, and Twelfth Corps by the Boonsborough turnpike, the Ninth Corps and Sykes’s division of the Fifth by the old Sharpsburg road;[63] the Ninth and Fifth to reinforce Franklin by the Rohrersville road, or move to Sharpsburg.

About two o’clock in the afternoon the advance of the Union army came in sight. General Porter had passed the Ninth Corps with his division under Sykes and joined Richardson’s division of the Second. These divisions deployed on the right and left of the turnpike and posted their batteries, which drew on a desultory fire of artillery, continuing until night. The morning of the 16th opened as the evening of the previous day closed, except for the arrival of the remainder of the Union troops. The Ninth Corps took post at the lower bridge opposite the Confederate right, the First, the other divisions of the Second, and the Twelfth Corps resting nearer Keedysville. The display of their finely appointed batteries was imposing, as seen from Sharpsburg Heights.

Before maturing his plans, General McClellan had to make a careful reconnoissance, and to know of the disposition to be made of the Confederate forces from Harper’s Ferry.

Of the latter point he was informed, if not assured, before he posted the Ninth Corps. Four batteries of twenty-pound Parrotts were planted on the height overlooking the Antietam on their right; on the crest near the Burnside Bridge, Weed’s three-inch guns and Benjamin’s twenty-pound Parrotts. At intervals between those were posted some ten or more batteries, and the practice became more lively as the day wore on, till, observing the unequal combat, I ordered the Confederates to hold their ammunition, and the batteries of the other side, seeming to approve the order, slackened their fire.

The Antietam, hardly worthy the name river, is a sluggish stream coming down from Pennsylvania heights in a flow a little west of south till it nears the Potomac, when it bends westward to its confluence. It is spanned by four stone bridges,—at the Williamsport turnpike, the Boonsborough-Sharpsburg turnpike, the Rohrersville turnpike, and another near its mouth. The third was afterwards known as the Burnside Bridge. From the north suburbs of Sharpsburg the Hagerstown turnpike leads north a little west two miles, when it turns east of north to the vanishing point of operations. A mile and a half from Sharpsburg on the west of this road is the Dunker chapel, near the southern border of a woodland, which spreads northward half a mile, then a quarter or more westward. East of the pike were open fields of corn and fruit, with occasional woodlands of ten or twenty acres, as far as the stream, where some heavier forests cumbered the river banks. General Lee’s line stood on the Sharpsburg Heights, his right a mile southeast of the village, the line extending parallel with the Hagerstown turnpike, three miles from his right, the left curved backward towards the rear, and towards the great eastern bend of the Potomac, near which were the cavalry and horse artillery. Along the broken line were occasional ridges of limestone cropping out in such shape as to give partial cover to infantry lying under them. Single batteries were posted along the line, or under the crest of the heights, and the battalions of the Washington Artillery, Cutts’s, and S. D. Lee’s.

In forming his forces for the battle, General McClellan divided his right wing, posted the Ninth Corps on his left, at the Burnside Bridge, under General Cox, and assigned the First Corps, under General Hooker, for his right flank. General Burnside was retained on his left. The plan was to make the main attack against the Confederate left, or to make that a diversion in favor of the main attack, and to follow success by his reserve.

At two P.M. of the 16th, Hooker’s First Corps crossed the Antietam at the bridge near Keedysville and a nearby ford, and marched against my left brigades, Generals Meade, Ricketts, and Doubleday commanding the divisions, battalions, and batteries of field artillery. The sharp skirmish that ensued was one of the marked preliminaries of the great battle; but the Federals gained nothing by it except an advanced position, which was of little benefit and disclosed their purpose.

General Jackson was up from Harper’s Ferry with Ewell’s division and his own, under Generals Lawton and Jones. They were ordered out to General Lee’s left, and took post west of the Hagerstown turnpike, the right of his line resting on my left, under Hood, Winder’s and Jones’s brigades on the front, Starke’s and Taliaferro’s on the second line, Early’s brigade of Ewell’s division on the left of Jackson’s division, with Hays’s brigade for a second; Lawton’s and Trimble’s brigades were left at rest near the chapel; Poague’s battery on Jackson’s front; five other batteries prepared for action. Following Jackson’s march to the left, General J. G. Walker came up with his two brigades, and was posted on my extreme right in the position left vacant by the change of Hood’s brigades.

General Hooker was joined, as he marched that afternoon, by his chief, who rode with him some little distance conversing of pending affairs. It subsequently transpired that Hooker thought the afternoon’s work ordered for his corps (thirteen thousand) so far from support extremely venturesome, and he was right. Jackson was up and in position with two divisions well on the flank of the attack to be made by Hooker. Hood with S. D. Lee’s batteries received Hooker’s attack, and arrested its progress for the day. If Jackson could have been put into this fight, and also the brigades under J. G. Walker, Hooker’s command could have been fought out, if not crushed, before the afternoon went out. He was beyond support for the day, and the posting along the Antietam was such—we will soon see—as to prevent effective diversion in his favor. Events that followed authorize the claim for this combination, that it would have so disturbed the plans of General McClellan as to give us one or two days more for concentration, and under that preparation we could have given him more serious trouble.

Hood’s skirmish line was out to be driven, or drawn in, but throughout the severe engagement his line of battle was not seriously disturbed. After night General Jackson sent the brigades of Trimble and Lawton, under General Lawton, to replace Hood’s men, who were ordered to replenish ammunition, and, after getting food, to resume their places on my right. Preparing for battle, General Jackson sent the brigade under General Early to support Stuart’s cavalry and horse artillery, and Lawton drew his brigade, under General Hays, to support his others on the right of Jackson’s division.

General Mansfield crossed during the night with the Twelfth Corps and took position supporting General Hooker’s command, with the divisions of Generals A. S. Williams and George S. Greene, and field batteries.

A light rain began to fall at nine o’clock. The troops along either line were near enough to hear voices from the other side, and several spats occurred during the night between the pickets, increasing in one instance to exchange of many shots; but for the most part there was silence or only the soft, smothered sound of the summer rain over all that field on which was to break in the morning the storm of lead and iron.
