Partly his elation was a manic reaction to the depression he had been feeling throughout most of the eleven days since Halleck’s order, issued in confirmation of Lincoln’s verbal instructions, gave him “command of the fortifications of Washington and of all the troops for [its] defense.” This had not been supplemented or broadened since. What he did beyond its limitations he did on his own—including the march into Maryland to interpose his army between Lee’s and the capital whose defense was his responsibility. Consequently, as he said later, he felt that he was functioning “with a halter around my neck.… If the Army of the Potomac had been defeated and I had survived I would, no doubt, have been tried for assuming authority without orders.” What the Jacobins wanted, he knew, was his dismissal in disgrace, and he had long since given up the notion that the President would support him in every eventuality. In fact, knowing nothing of Lincoln’s defiance of a majority of the cabinet for his sake, he no longer trusted the President to stand for long between him and the political clamor for his removal; and he was right. Back at the White House, after telling Hay, “McClellan is working like a beaver. He seems to be aroused to doing something after the snubbing he got last week,” Lincoln added thoughtfully: “I am of the opinion that this public feeling against him will make it expedient to take important command from him … but he is too useful just now to sacrifice.”
All this while, moreover, Halleck had been giving distractive twitches to the telegraphic lines attached to the halter. Though Banks had three whole corps with which to man the capital fortifications—Heintzelman’s, Sigel’s, and Porter’s, which, together with the regular garrison, gave him a total defensive force of 72,500 men—the general in chief swung first one way, then another, alternately tugging or nudging, urging caution or headlong haste. Four days ago he had wired: “It may be the enemy’s object to draw off the mass of our forces, and then attempt to attack us from the Virginia side of the Potomac. Think of this.” Two days later he was calmer: “I think the main force of the enemy is in your front. More troops can be spared from here.” Today, however, his fears were back, full strength: “Until you know more certainly the enemy forces south of the Potomac you are wrong in thus uncovering the capital.” McClellan, his natural caution thus enlarged and played on—he estimated Lee’s army at 120,000 men, half again larger than his own—pushed gingerly northwestward up the National Road, which led from Washington to Frederick, forty miles, then on through Hagerstown and Wheeling, out to Ohio.
He averaged about six miles a day, despite the fact that he had reorganized his army into two-corps “wings” in order to march by parallel roads rather than in a single column, which would have left the tail near Washington while the head was approaching Frederick. The right wing, assigned to Burnside, included his own corps, still under Reno, and McDowell’s, now under Hooker, who had already won the nickname “Fighting Joe.” The center wing was Sumner’s and included his own and Banks’ old corps, now under the senior division commander, Brigadier General Alpheus Williams. The left wing, Franklin’s, included his own corps and the one division so far arrived from Keyes’, still down at Yorktown. Porter’s corps, which was released to McClellan on the 12th, the day his advance units reached Frederick, was the reserve. Including the troops arrived from West Virginia and thirty-five new regiments distributed throughout the army since its retreat from Manassas, McClellan had seventeen veteran divisions, with an average of eight brigades in each of his seven corps; or 88,000 men in all. Yet he believed himself outnumbered, and he could not forget that the army he faced—that scarecrow multitude of lean, vociferous, hairy men who reminded even noncombatants of wolves—had two great recent victories to its credit, while his own had just emerged from the confusion and shame of one of the worst drubbings any American army had ever suffered. Nor could he dismiss from his mind the thought of what another defeat would mean, both to himself and to his country. Despised by the leaders of the party in power, mistrusted by Lincoln, badgered by Halleck, he advanced with something of the manner of a man walking on slippery ice through a darkness filled with wolves.
It was at Frederick, that “goodly city,” that the gloom began to lift. “I can’t describe to you for want of time the enthusiastic reception we met with yesterday in Frederick,” he wrote his wife next morning. “I was nearly overwhelmed and pulled to pieces. I enclose with this a little flag that some enthusiastic lady thrust into or upon Dan’s bridle. As to flowers—they came in crowds! In truth, I was seldom more affected.… Men, women, and children crowded around us, weeping, shouting, and praying.” Then, near midday, his fears were abolished and his hopes were crowned. “Now I know what to do,” he exclaimed when he read Special Orders 191, and one of the first things he did was share his joy with Lincoln in a wire sent at noon. In his elation he had the sound of a man who could not stop talking:
“I have the whole rebel force in front of me, but am confident, and no time shall be lost. I have a difficult task to perform, but with God’s blessing will accomplish it. I think Lee has made a gross mistake, and that he will be severely punished for it. The army is in motion as rapidly as possible. I hope for a great success if the plans of the rebels remain unchanged. We have possession of Catoctin. I have all the plans of the rebels, and will catch them in their own trap if my men are equal to the emergency. I now feel that I can count on them as of old.… My respects to Mrs. Lincoln. Received most enthusiastically by the ladies. Will send you trophies.”
He said he would lose no time, and five days ago he had told Halleck, “As soon as I find out where to strike, I will be after them without an hour’s delay.” But that did not mean he would be precipitate. In fact, now that the once-in-a-lifetime opportunity was at hand, its very magnitude made him determined not to muff it as a result of careless haste. Besides, despite its fullness in regard to the location of the Confederate detachments, the order gave him no information as to their various strengths. For all he knew, Longstreet and Hill had almost any conceivable number of men at Boonsboro, and the nature of the terrain between there and Frederick afforded them excellent positions from which to fight a delaying action while the other half of their army shook itself together and rejoined them—or, worse still, moved northward against his flank. He already had the Catoctins, as he said, but beyond them reared South Mountain, the lofty extension of the Blue Ridge. The National Road crossed this range at Turner’s Gap, with Boonsboro just beyond, while six miles south lay Crampton’s Gap, pierced by a road leading down to Harpers Ferry from Buckeystown, where Franklin’s left wing was posted, six miles south of Frederick. These roads and gaps gave McClellan the answer to his problem. He would force Turner’s Gap and descend on Boonsboro with his right and center wings, smashing Longstreet and Hill, while Franklin marched through Crampton’s Gap and down to Maryland Heights, where he would strike the rear of Anderson and McLaws, capturing or brushing their men off the mountaintop and thereby opening the back door for the escape of the 12,000 Federals cooped up in Harpers Ferry. That way, too, the flank of the main body would be protected against an attack from the south, in case resistance delayed the forcing of the upper gap.
By late afternoon his plans were complete, and at 6.20 he sent Franklin his instructions. After explaining the situation at some length, he told him: “You will move at daybreak in the morning.… Having gained the pass”—Crampton’s Gap—“your duty will be first to cut off, destroy, or capture McLaws’ command and relieve [Harpers Ferry].” After saying, “My general idea is to cut the enemy in two and beat him in detail,” he concluded: “I ask of you, at this important moment, all your intellect and the utmost activity that a general can exercise.” Intellect and activity were desirable; haste, apparently, was not. Just as he did not ask it of himself, so he did not ask it of Franklin. Lee’s disjointed army lay before him, and the best way to pick up the pieces—as he saw it—was deliberately, without fumbling. The army would get a good night’s sleep, then start out fresh and rested “at daybreak in the morni
ng.”
And so it was. At sunrise, Franklin’s 18,000—who should indeed have been rested; they had seen no combat since the Seven Days, and not a great deal of it then except for the division that reinforced Porter at Gaines Mill—pushed westward out of Buckeystown, heading for the lower gap, a dozen miles away. The other two wings, 70,000 men under Sumner and Burnside, with Porter bringing up the rear, moved down the western slope of the Catoctins, then across the seven-mile-wide valley toward Turner’s Gap, a 400-foot notch in the 1300-foot wall of the mountain, where a fire fight was in progress. They moved in three heavy columns, along and on both sides of the National Road, and to one of the marchers, down in the valley, each of these columns resembled “a monstrous, crawling, blue-black snake, miles long, quilled with the silver slant of muskets at a ‘shoulder,’ its sluggish tail writhing slowly up over the distant eastern ridge, its bruised head weltering in the roar and smoke upon the crest above, where was being fought the battle of South Mountain.”
McClellan was there beside the pike, astride Dan Webster, the central figure in the vast tableau being staged in this natural amphitheater, and the men cheered themselves hoarse at the sight of him. It seemed to one Massachusetts veteran that “an intermission had been declared in order that a reception might be tendered to the general in chief. A great crowd continually surrounded him, and the most extravagant demonstrations were indulged in. Hundreds even hugged the horse’s legs and caressed his head and mane.” This was perhaps the Young Napoleon’s finest hour, aware as he was of all those thousands of pairs of worshipful eyes looking at him, watching for a gesture, and the New England soldier was pleased to note that McClellan did not fail to supply it: “While the troops were thus surging by, the general continually pointed with his finger to the gap in the mountain through which our path lay.”
Harvey Hill was watching him, too, or anyhow he was looking in that direction. Seeing from the notch of Turner’s Gap, which he had been ordered to hold with his five-brigade division, the serpentine approach of those four Union corps across the valley—twelve divisions with a total of thirty-two infantry brigades, not including one corps which was still beyond the Catoctins—he said later that “the Hebrew poet whose idea of the awe-inspiring is expressed by the phrase, ‘terrible as an army with banners,’ [doubtless] had his view from the top of a mountain.” He experienced mixed emotions at the sight. Although it was, as he observed, “a grand and glorious spectacle, and it was impossible to look at it without admiration,” he added that he had never “experienced a feeling of greater loneliness. It seemed as though we were deserted by ‘all the world and the rest of mankind.’ ”
Despite the odds, all too apparent to anyone here on the mountaintop, he had one real advantage in addition to the highly defensible nature of the terrain, and this was that he could see the Federals but they could not see him. Consequently, McClellan knew little of Hill’s strength, or lack of it, and nothing at all of his loneliness. He thought that Longstreet, in accordance with Special Orders 191, was there too; whereas he was in fact at Hagerstown, a dozen miles away. Lee had sent him there from Boonsboro, three days ago, to head off a blue column erroneously reported to be advancing from Pennsylvania. After protesting against this further division of force—“General,” he said in a bantering tone which only partly covered his real concern, “I wish we could stand still and let the damned Yankees come to us”—Longstreet marched his three divisions northward through the heat and dust. As a result, while McClellan back in Frederick was saying that he intended “to cut the enemy in two,” Lee had already obliged him by cutting himself in five:
It was puzzling, this manifest lack of caution on McClellan’s part, until late that night a message from Stuart explained the Young Napoleon’s apparent change of character. A Maryland citizen of southern sympathies had happened to be at Federal headquarters when the lost order arrived, and he had ridden west at once, beyond the Union outposts, to give the news to Stuart, who passed it promptly on to Lee. So now Lee knew McClellan knew his precarious situation, and now that he knew he knew he moved to counteract the disadvantage as best he could. He sent for Longstreet and told him to march at daybreak in support of Hill, whose defense of Turner’s Gap would keep the Federal main body from circling around South Mountain to relieve the Harpers Ferry garrison by descending on McLaws. Longstreet protested. The march would have his men so blown that they would be in no shape for fighting when they got there, he said, and he urged instead that he and Hill unite at Sharpsburg, twelve miles south of Hagerstown and half that far from Boonsboro; there, near the Potomac, they could organize a position for defense while awaiting the arrival of the rest of the army, or else cross in safety to Virginia in case the troops from Harpers Ferry could not join them in time to meet McClellan’s attack. Lee overruled him, however, and Longstreet left to get some sleep. After sending word to McLaws of the danger to his rear and stressing “the necessity of expediting your operations as much as possible,” Lee received a note from Longstreet repeating his argument against opposing the Federals at South Mountain. Later the Georgian explained that he had not thought the note would alter Lee’s decision, but that the sending of it “relieved my mind and gave me some rest.” What effect it had on Lee’s rest he did not say. At any rate, he received no reply, and the march for Turner’s Gap began at dawn.
As usual, once he got them into motion, Longstreet’s veterans marched hard and fast, trailing a long dust cloud in the heat. Shortly after noon they came within earshot of the battle Hill was waging on the mountain. The pace quickened on the upgrade. About 3 o’clock, nearing the crest, Lee pulled off to the side of the road to watch the troops swing past him. Though his hands were still in splints, which made for awkward management of the reins, he was mounted; he could abide the ambulance no longer. Presently the Texas brigade approached. “Hood! Hood!” they yelled when they saw Lee by the roadside. For two weeks Hood had been in arrest, but now that they were going into battle they wanted him at their head. “Give us Hood!” they yelled. Lee raised his hat. “You shall have him, gentlemen,” he said.
When the tail of the column came abreast he beckoned to the tall young man with the tawny beard and told him: “General, here I am just on the eve of entering into battle, and with one of my best officers under arrest. If you will merely say that you regret this occurrence”—referring to the clash with Evans over the captured ambulances—“I will release you and restore you to the command of your division.” Hood shook his head regretfully and replied that he “could not consistently do so.” Lee urged him again, but Hood again declined. “Well,” Lee said at last, “I will suspend your arrest till the impending battle is decided.” Beaming, Hood saluted and rode off. Presently, from up ahead, loud shouts and cheers told Lee that the Texans had their commander back again.
It was well that they did, for they had need of every man they could muster, whatever his rank. Hill had been fighting his Thermopylae since early morning, and events had shown that the gap was by no means as defensible as it had seemed at first glance. High ridges dominated the notch from both sides, and there were other passes north and south, so that he had had to spread his small force thin in order to meet attacks against them all. Coming up just as Hill was about to be overwhelmed—one brigade had broken badly when its commander Brigadier General Samuel Garland was killed, and others were reduced to fighting Indian-style, scattered among the rocks and trees—Longstreet counterattacked on the left and right and managed to stabilize the situation until darkness ended the battle. McClellan had had about 30,000 men engaged, Lee about half that many. Losses were approximately 1800 killed and wounded on each side, with an additional 800 Confederates taken captive. Among the dead was Jesse Reno, shot from his saddle just after sundown while making a horseback inspection of his corps. Lieutenant Colonel Rutherford B. Hayes of the 23d Ohio, fifteen years away from the Presidency, was wounded. Sergeant William McKinley, another future President from that regiment, was unhurt; the bullet that w
ould get him was almost forty years away.
For Lee it was a night of anxiety. He had saved his trains and perhaps delayed a showdown by holding McClellan east of the mountain, but he had done this at a cost of nearly 3000 of his hard-core veterans. What was more, he knew he could do it no longer: Hill and Longstreet both reported that the gap could not be held past daylight, and defeat here on the mountain would mean annihilation. The only thing to do, Lee saw, was to adopt the plan Old Pete had favored so argumentatively the night before. Gone were his hopes for an invasion of Pennsylvania, the destruction of the Susquehanna bridge, the descent on Philadelphia, Baltimore, or the Union capital. Gone too was his hope of relieving Maryland of what he called her foreign yoke. Outnumbered worse than four to one, this half of the army—which in fact was barely more than a third: fourteen brigades out of the total forty—would have to retreat across the Potomac, and the other half would have to abandon its delayed convergence on Harpers Ferry. For Jackson and Walker this would not be difficult, but McLaws was already in the gravest danger. Soon after nightfall Lee sent him a message admitting defeat: “The day has gone against us and this army will go by Sharpsburg and cross the river. It is necessary for you to abandon your position tonight.” McLaws of course would not be able to do this over the Ferry bridge, which was held by the Federal garrison; he would have to cross the Potomac farther upstream. Lee urged him, however, to do this somewhere short of Shepherdstown, which was just in rear of Sharpsburg. He wanted that ford clear for his own command, which would be retreating with McClellan’s victorious army hard on its heels.
The evacuation began with Hill, followed by Longstreet; the cavalry brought up the rear. Obliged to abandon his dead and many of his wounded there on the mountain where they had fallen, Lee did not announce that he intended to withdraw across the Potomac, nor did he tell the others that he had instructed McLaws to abandon Maryland Heights. But news that arrived while the retreat was just getting under way confirmed the wisdom, indeed the necessity, of his decision. Cramp-ton’s Gap, six miles south, had been lost by the troopers sent to defend it: which not only meant that the Federals were pouring through, directly in rear of McLaws, but also that they were closer to Sharpsburg than Hill and Longstreet were. Unable to count any longer on McClellan’s accustomed caution and hesitation, Lee saw that the march would have to be hard and fast, encumbered though he was with all his trains, if he was to get there first. Whereupon, with the situation thus at its worst and his army in graver danger of piecemeal annihilation than ever, Lee displayed for the first time a side to his nature that would become more evident down the years. He was not only no less audacious in retreat than in advance, but he was also considerably more pugnacious, like an old gray wolf wanting nothing more than half a chance to turn on whoever or whatever tried to crowd him as he fell back. And presently he got it.
