CHAPTER XLII
THE CAMPAIGNS OF CHICKAMAUGA AND CHATTANOOGA
While Lee was fighting his tremendous campaigns in Virginia, Maryland and Pennsylvania, and while Grant was battling for Vicksburg, two other armies confronted each other near the southern border line of Tennessee. Rosecrans had command of the Federal forces near Murfreesboro, and Braxton Bragg was in charge of the Confederates at Chattanooga. The position of each of these armies was a serious threat to the other side. If Bragg should be left unoccupied by his enemy it was easily within his power to make a dangerous dash towards Cincinnati or Louisville, while if he should withdraw from Rosecrans's front there was nothing to prevent that general from "marching through Georgia," to Mobile or Savannah or Charleston.
Grant, besieging Vicksburg, asked for reinforcements from Rosecrans by way of warding off that blow in the rear which he feared that Johnston might deliver and at the same time Johnston begged for reinforcements from Bragg in order that he might deliver such a blow. Each of the commanders at Murfreesboro and Chattanooga realized the necessity of remaining where he was so long at least as his adversary should remain. The result was that neither sent the reinforcements for which his brother in the field was so clamorously calling.
These two armies for a long time stood watching each other, each waiting for the other to make some movement that would give it opportunity. In the meanwhile the cavalry on either side was engaged in making some of the most picturesque raids that were at any time made during the struggle. On both sides the cavalry had by this time learned its business, and realized its possibilities of independent action in the enemy's country. The Federal cavalier, Grierson, swept through Mississippi carrying desolation wherever he went. The Confederates, Wheeler and Forrest, rushed hurricanelike through the country north, battling here and there with such forces as they met. Gordon Granger and Colonel Streight on the Federal side were swinging swords almost continually.
The operations of this kind were too many, and strategically of too little importance to call for detailed description in a general history of the war. But two of them were so dramatic in their conduct and ending that they must be mentioned here. One of these was the attempt of Colonel Streight with about 2,000 men to march around Bragg's army, and cut off his communications. This raid was made early in April, and Forrest followed it with all the vigor that usually characterized that general's operations. The two forces were in constant battle as the one swept onward and the other followed. Streight meanwhile was working havoc with Confederate depots of supplies, with railroad property, and other possessions of his enemy. Finally on the third of May, Forrest succeeded in placing himself in a position where he was justified in demanding the surrender of Streight's force. He made the demand boldly and threateningly and Streight surrendered only to learn after the capitulation was made that the men under his command really outnumbered those of Forrest. It was Forrest's boast afterward that in this case he had "won by a pure bluff."
The other raid which rises into historical importance was that of John Morgan north of the Ohio. Starting in July with a force of 3,000 Confederate cavalrymen and ten guns Morgan crossed the Ohio river into Indiana, capturing two steamers and using them as ferryboats. He then swept through Indiana towards Cincinnati, burning mills and bridges, tearing up railroads, and spreading terror in his pathway. But resolution accompanied the terror. Every man in all that region who could bear a gun turned out to fight the raiders and to destroy them before they should succeed in recrossing the river. This was accomplished at last with the aid of gunboats and steamboats. Morgan was compelled to surrender a small remnant of his force, and was sent for safe-keeping to the Ohio state prison, from which he later escaped by digging.
All these operations, of course, were subsidiary to the general purposes of the campaign.
Rosecrans was an exceedingly capable strategist and upon this occasion, more conspicuously than on any other during his career, his capacity in that way was demonstrated.
Bragg occupied Chattanooga, the strategic importance of which has been explained in an earlier chapter. The position was practically impregnable by any form of direct assault; for Rosecrans to have hurled his army against it would have been an act of well-nigh suicidal folly. In such an assault he must have lost ten men for every one of his enemy's men whom he could hope to put hors de combat. Yet it was necessary for Rosecrans to get Bragg out of Chattanooga. In order to do so he pushed a part of his army southward, threatening an invasion of Georgia. That state was defenseless except in so far as Bragg's army defended it. Rosecrans's movement, therefore, quickly compelled Bragg to withdraw from his strong and threatening position in order to head off what he supposed to be that southward movement that Sherman afterward made, and that is known in history as "the march to the sea." As soon as he quitted Chattanooga, Rosecrans occupied that place about the middle of September.
It was apparently good policy for Rosecrans instantly and aggressively to follow his foe, and he did so in spite of the fact that his three corps were dangerously separated at a time of heavy rains, when the roads were bad, streams out of their banks, marching difficult, and promptitude of movement impossible. In the meantime Bragg had been heavily reinforced by Longstreet's corps sent out by Lee to save this situation. Thus strengthened Bragg turned about with intent to assail his adversary, and perhaps to destroy him. On the nineteenth of September the two armies met on the banks of Chickamauga creek. There for two days raged one of the great battles of the war.
Rosecrans brought into the action about 55,000 men and Bragg had perhaps 10,000 more. It was Bragg who made the attack. As the lines lay, the Confederate right and the Federal left extended toward Chattanooga.
Bragg's plan of battle was to fall upon the Federal left, crush it, bend back the line, and place himself between the Federal army and its base. There could have been no better plan of battle formed, but it was not executed in the best fashion possible. Had Bragg fully realized the superiority of Longstreet to his other corps commanders, and still more the superiority of Longstreet's men who had fought at Fredericksburg, Chancellorsville, Antietam and Gettysburg, he would have placed Longstreet upon his right, in order that the blow might be delivered with all that was possible of crushing force. Instead of that he assigned the force of General Leonidas Polk to that position. Polk was a West Point graduate, but soon after graduation he had become a clergyman of the Episcopal church, and for many years past had been a bishop in that church. A fact that had more importance perhaps, was that Polk's men had not been trained by the experience of Lee's tremendous onslaughts to the best work of the soldier, and unfortunately for Bragg, but fortunately for Rosecrans, that left wing of the Federal army upon which the main assault was made, was under command of General George H. Thomas, one of the most determined fighters on either side during the war.
Under Polk the assault was made loosely, and without that perfect concert of action which Longstreet, had he been in command, would have brought to bear. Thomas met it with obstinate resistance, and when opportunity offered, with counter attacks that greatly interfered with Bragg's plans. Nevertheless, the fighting was obstinate and destructive to both sides. In the end Polk succeeded in forcing Thomas's line backwards for a time, but before nightfall the Federal general had recovered the greater part of his ground, and when the first day's fighting ended the position of the two armies was practically the same that had existed in the morning.
About eleven o'clock on the next morning the battle was resumed with fury. Polk again assailed Thomas, and Thomas urgently asked for reinforcements with which to repel the assault. On that part of the line the struggle continued for hours with varying and not unequal success, the advantage lying on the whole with the Confederates. But later in the day Longstreet, who commanded the right center of Bragg's line, made a tremendous assault of that kind which had been rendered familiar to the fighters in Virginia by repeated experience. He swept everything before him. He made a gap in Rosecrans's line crushing its center, separating its wings from each other and driving it into confused retreat. Thomas alone held his force together, and fought the matter out to a finish. In spite of the fact clearly apparent to him that Rosecrans was defeated, and three fifths of his army destroyed, Thomas continued the bloody contest with a fury that knew no flinching, and hesitated at nothing of human sacrifice in the achievement of its purposes. But for Thomas's obstinacy, skill and courage the Federal defeat at Chickamauga would have been a repetition of the disaster at Chancellorsville.
During the night Thomas succeeded in withdrawing his command, and the Federal army fell back to Chattanooga, taking refuge behind the fortifications there. Each army had lost in this struggle from 15,000 to 20,000 men. The exact figures are nowhere procurable.
Bragg had won a great victory, but he had not succeeded in regaining possession of Chattanooga. His enemy held that strong, strategic position. It was therefore his next task to besiege the foe there, and either by fighting or by maneuvering to drive him out of the place.
Two mountain heights, the one known as Lookout mountain and the other as Missionary Ridge, overlook the town, and command many of its approaches. When the battle was over Bragg promptly advanced and seized upon these heights. By doing so he succeeded in placing Chattanooga in a state of siege, stopping the navigation of the river, and cutting off all of Rosecrans's communications, with the exception of one highly inadequate mud road.
It is a maxim of military science that the army which can besiege a position can always capture it in the end unless the beleaguered place is relieved from the outside. Chattanooga was relieved from the outside in an exceedingly quiet, but exceedingly effective way. Ulysses S. Grant--at last a major general in the regular army and in full command of the western department--went thither to supersede Rosecrans in command. The coming of this one silent and unostentatious man meant more to the Federal forces in that quarter than the arrival of half a dozen army corps would have signified. Grant got to Chattanooga on the twenty-third of October, 1863, and set to work at once with his practical common sense to meet and solve the problems of the situation.
He found the army half starved for lack of routes of communication with its bases of supply. He instantly set his men at work to open a new road which the facetious soldiers named the "cracker line," and which connected Chattanooga with a point on the river to which steamboats could come with abundant supplies. This relieved the Federal army in Chattanooga of its condition as an army in a state of siege. It made of it instead an army in the field, well fed, properly supplied, and ready for march or battle, as its commander might direct.
Having thus relieved the distresses of the army he had been sent to command, Grant's next thought was to employ that army in some profitable way. The Confederates, strongly fortified, held Lookout mountain and Missionary Ridge, and stretched their line for twelve miles across the Chattanooga valley. Grant decided to dislodge them. He could not do so with the forces assembled at Chattanooga, but at last the authorities at Washington had recognized him as a man worthy to command, and had placed the entire department under his control, and all its armies were at his disposal. Grant believed in Sherman, and mightily trusted him. At every point in his career where Sherman could be called to his aid Grant summoned that commander, and employed his genius as the most effective instrument for the accomplishment of his own purposes. It is not too much to say that Sherman was to Grant quite all that Stonewall Jackson was to Lee--a lieutenant to whom he might assign the most difficult enterprises with full assurance that they would be executed with all the skill, determination, valor and sagacity that it was possible to bring to bear upon them as military operations.
So when Grant determined to dislodge the Confederates from Lookout mountain and Missionary Ridge his first step was to summon Sherman to join him with the corps then under Sherman's command.
Certain military necessities delayed Sherman's march, and he did not reach the position at Chattanooga until the fifteenth of November. His arrival swelled Grant's force to about 80,000 men, while Bragg's army was weakened by the detachment of Longstreet with 20,000 men to operate against Burnside, who was commanding at Knoxville, Tennessee. The Confederate force in possession of Lookout mountain and Missionary Ridge was thus considerably inferior to the army with which Grant prepared to assail it. But the Confederates were strongly posted and on a part of their line, at least, they were well entrenched.
Grant's plan of battle was simple, as his plans of battle usually were. He ordered Sherman to carry Missionary Ridge, which constituted the extreme right of the Confederate position, while Thomas and Hooker should so far engage the remainder of the line as to prevent the reinforcement of that point upon which his chief assault was to be made. If he could accomplish this Bragg must either retreat, abandoning his threat against Chattanooga, or he must seek some point at which to give battle again with a force so far weakened by detachment as to render battle a dangerous alternative for him.
Sherman advanced on the twenty-fourth of November. His assault was repulsed and for the time unsuccessful. Hooker, in the meanwhile, exceeded his orders, and did a good deal more fighting than Grant had intended him to do. It was his assigned duty merely to engage that part of the Confederate lines which lay in front of him, sufficiently to prevent the sending of any force from it to reinforce the Confederate right. But Hooker was by instinct a fighter at all times. And on this occasion he pushed his men boldly into a fight that his commanding officer had not intended. His force climbed to the extreme summit of the mountain, passing a zone of mist and fog as they went. Having reached the summit they routed the Confederates there and made themselves masters of the heights. The fact that they passed through this fog zone on their way up led to the poetic nicknaming of this action as the "Battle above the Clouds." It was not, properly speaking, a battle at all, and it was not above the clouds in the sense in which that phrase impresses the ordinary mind.
On the twenty-fifth Grant pushed Thomas again into the fight, and assailed the position on Missionary Ridge. A very gallant and very vigorous action followed. It resulted in the Federals carrying the Ridge, sweeping everything before them, and driving Bragg's army into full retreat. He retired with what remained of his force to Dalton, Georgia, and almost immediately afterward Gen. Joseph E. Johnston was ordered to take command in that quarter in his stead.
The campaign had been dramatic in many of its features, and peculiarly picturesque in some of them. It had cost the lives of from six to ten thousand men on either side. It left the Federals masters of Chattanooga, placing the Confederates in an uncertain defensive position against which future operations were comparatively easy.
