The Union center at which Longstreet pointed his attack was held by Brig. Gen. Thomas J. Wood’s Division which had replaced Negley’s Division in the line when the latter had reinforced Thomas early in the morning. To the immediate left of Wood were the troops of Brannan’s Division, and on Brannan’s left, Maj. Gen. Joseph J. Reynolds’ Division.

An hour before noon as the Confederate right wing poised to strike, an irreparable blunder occurred on the Union side. A staff officer riding from Thomas’ headquarters near Kelly Field reported to Rosecrans that he had noticed Brannan’s Division was out of line and believed “General Reynolds’ right was exposed.” Rosecrans, without further investigation, immediately ordered Wood to “close up on Reynolds as fast as possible and support him.” In order to do this, Wood had to pull his division out of line and march behind Brannan’s Division toward Reynolds. Wood’s division had left its place in the line, creating a true gap where none had actually existed before, and had started to march northward behind Brannan when Longstreet’s column of five divisions accidentally struck into the gap.

Longstreet’s attack hit Wood’s and Brannan’s Divisions on their exposed flank and drove them from the immediate field of battle. On the other side of the gap the Confederates struck Brig. Gen. Jefferson C. Davis’ Division, which was marching up to take Wood’s place in the line, and Maj. Gen. Philip H. Sheridan’s Division in flank. In avery short time the entire Union right flank was in disorder and driven from the field. Wilder’s brigade on the extreme right made a valiant stand for a while, employing to good effect the heavy fire power of the Spencer repeating carbine with which it was armed. Nothing, however, seemed to daunt the onrush of the Confederates, and Wilder withdrew for fear of being cut off from escape.

The routed divisions from the Union right withdrew northwestward through McFarland’s Gap to Rossville. Generals Rosecrans, Crittenden, and McCook were caught in the breakthrough and fled the field. General Thomas was now in command of the Union forces left there.

The altered conditions of the battlefield now dictated a change in Confederate strategy. The original plan of enveloping the Union left changed to a sweep from the Union right to the left. A pause in the fighting enabled Thomas to form a new line quickly to his rear on Snodgrass Hill, almost at a right angle with the Union left. From this vantage point he met the onslaught of Longstreet’s troops with such stubborn and determined resistance on that Sunday afternoon that he earned the name “Rock of Chickamauga.”

The Union line on Snodgrass Hill was composed of Brannan’s Division with fragments of Wood’s, Negley’s, and Van Cleve’s Divisions. Longstreet vigorously assaulted the line again and again and nearly succeeded in enveloping Brannan’s right. Confederate success seemed assured as Thomas’ troops were hard hit and were short of ammunition, but at this moment unexpected reinforcements reached General Thomas.

General Granger, without orders and following the sound of battle, had hastened to the aid of Thomas. He arrived at Snodgrass Hill at a very opportune moment and just in time to stop the Confederatesfrom enveloping Brannan’s right. A fierce engagement took place as Brig. Gen. James B. Steedman’s Division of Granger’s Corps forced the southern troops from the crest of the hill.

Midafternoon found Longstreet once again attempting to wrest the hill from Thomas’ troops, using McLaw’s, Hindman’s, and Bushrod Johnson’s Divisions, and again he was repulsed. Later in the afternoon, Longstreet asked Bragg for reinforcements but was told none were available and that the right wing “had been beaten back so badly that they could be of no service” to him. Longstreet determined to make one more effort. He formed a column of such troops as were available and again assaulted the hill. The fight was desperate and lasted until nightfall. The Union troops repulsed some of the Confederate charges with the bayonet as their ammunition was nearly exhausted. Finally, Longstreet pushed Steedman back to the next ridge and occupied the ground to the right of Brannan.

The left of the Union line around Kelly Field spent a relatively quiet afternoon compared to their comrades on Snodgrass Hill. However, about 4 p.m., the divisions of Hill’s corps and part of Walker’s again assaulted the Union positions there. By 6 p.m., Cheatham’s Division had joined the attack. This attack succeeded in enveloping the Union left, and the road to Rossville, through Rossville Gap, was cut off for the moment.

In the meantime, Thomas received orders from Rosecrans to “Assume command of all the forces, and with Crittenden and McCook take a strong position and assume a threatening attitude at Rossville.” Although Thomas received these orders with little delay, it was lateafternoon before he sent instructions to Reynolds to begin the withdrawal and move into position to cover the retirement of the other troops on the left. In executing this movement, Reynolds was forced to drive off the Confederate troops who had begun to envelop the Union left. The Union army withdrew in relatively good order. The troops holding Kelly Field moved out first, followed by those who had stubbornly resisted Longstreet’s attacks upon Snodgrass Hill.

While the retreat from the battlelines may have been in “good order,” General Beatty’s description of the march to Rossville amply describes the scene: “The march to Rossville was a melancholy one. All along the road, for miles, wounded men were lying. They had crawled or hobbled slowly away from the fury of the battle, become exhausted, and lain down by the roadside to die.” Beatty reached Rossville between “ten and eleven” and reported, “At this hour of the night (eleven to twelve o’clock) the army is simply a mob. There appears to be neither organization nor discipline. The various commands are mixed up in what seems to be inextricable confusion.”

Nevertheless, Thomas placed his forces at Rossville Gap and along Missionary Ridge in preparation against further attacks. The morning of the 21st found the Union Army of the Cumberland more or less reorganized. With the exception of some skirmishing, the Union forces were not molested.

The losses on both sides were appalling and the percentages surprisingly equal. The following tabulation of casualties at the Battle of Chickamauga is based on Thomas L. Livermore’sNumbers and Losses in the Civil War in America, 1861-65:

Thomas remained in position at Rossville throughout the 21st, but it was evident that the Confederates could turn his right flank and cut him off from Chattanooga. He suggested to Rosecrans that the Union Army concentrate at Chattanooga. In anticipation of receiving an order to withdraw to the town, Thomas instructed his officers to prepare their commands for the movement. Rosecrans adopted the suggestion and that evening Thomas withdrew the Union forces to Chattanooga. All wagons, ambulances, and surplus artillery had already departed for Chattanooga during the day. By morning of September 22, all Union troops were in position in the town.

The situation in which the men in blue found themselves in Chattanooga was not pleasant. The Tennessee River walled them in on the north, although a pontoon bridge and two ferries offered escape possibilities. Lookout Mountain blocked the way on the west, and Missionary Ridge to the east and south, now held by the Confederates, completed the circle.

Bragg issued orders for the pursuit of the Army of the Cumberland, then countermanded them. Instead, the Confederate troops began to take up siege positions around Chattanooga. In these positions the Confederates dominated the Union lines. Bragg’s men controlled all the railroads leading into the town; Confederate batteries and sharpshooters commanded the Tennessee River, and river traffic ceased; they controlled the roads on the south side of the river and kept under fire the one road north of the river leading to Bridgeport, the nearest Union supply base. Only the road over Walden’s Ridge and down through the Sequatchie Valley to Bridgeport was open to General Rosecrans.

As early as September 13, General in Chief Halleck ordered reinforcements sent to Rosecrans. His dispatches on September 13, 14, and 15 to Major Generals Hurlbut at Memphis and Grant and Sherman at Vicksburg directed the troop movements. These dispatches, however, were delayed for several days en route from Cairo to Memphis and, in the meantime, the Battle of Chickamauga was fought. Grant received the orders on the 22nd and immediately instructed four divisions under Sherman to march to Chattanooga.

One division of the Seventeenth Corps, already in transit from Vicksburg to Helena, Ark., was ordered to proceed on to Memphis. General Sherman quickly brought three divisions of his Fifteenth Army Corps from the vicinity of the Big Black River into Vicksburg, where they embarked as fast as water transportation could be provided. By October 3, all of the movement of 17,000 men was under way.

The route of travel was by boat to Memphis, then by railroad and overland marches to Chattanooga. From Memphis the troops followed closely the Memphis and Charleston Railroad, which Sherman was ordered to repair as he advanced. By November 15, the troops were at Bridgeport, Ala., having traveled a distance of 675 miles.

When the War Department in Washington received word that the Army of the Cumberland was besieged in Chattanooga, it considered the situation so critical that President Lincoln was called out of bed late at night to attend a council meeting. This meeting occurred on the night of September 23, and is described by Nicolay and Hay:

Immediately on receipt of Rosecrans’ dispatch, Mr. Stanton sent one of the President’s secretaries who was standing by to the Soldier’s Home, where the President was sleeping. A little startled by the unwonted summons,—for this was “the first time” he said, Stanton had ever sent for him,—the President mounted his horse and rode in through the moonlight to the War Department to preside over an improvised council to consider the subject of reinforcing Rosecrans.There were present General Halleck, Stanton, Seward and Chase of the Cabinet; P. H. Watson and James A. Hardie of the War Department, and General D. C. McCallum, Superintendent of Military Transportation. After a brief debate, it was resolved to detach the Eleventh and Twelfth Corps from the Army of the Potomac, General Hooker to be placed in command of both....

The movement of the Eleventh and Twelfth Army Corps from the Army of the Potomac to Tennessee eclipsed all other such troop movements by rail up to that time. It represented a high degree of cooperation between the railroads and the government and was a singular triumph of skill and planning. It also shows the great importance the War Department attached to the Chattanooga campaign.

The troops began to entrain at Manassas Junction and Bealton Station, Va., on September 25, and 5 days later on September 30 the first trains arrived at Bridgeport, Ala. The route traveled was by way of Washington, D. C.; Baltimore, Md.; Bellaire and Columbus, Ohio; Indianapolis, Ind.; Louisville, Ky.; Nashville, Tenn.; and Bridgeport, Ala. Several major railroad lines, including the Baltimore and Ohio, Central Ohio, Louisville and Nashville, and Nashville and Chattanooga were involved.

Not all of the troops, however, made such good time as the first trains, and for the majority of the infantry the trip consumed about 9 days. The movement of the artillery, horses, mules, baggage, and impedimenta was somewhat slower, but by the middle of October, all were in the vicinity of Bridgeport ready to help break the siege.

These two corps under Maj. Gen. Joseph Hooker, comprising 20,000 troops and more than 3,000 horses and mules, traveled 1,157 miles. Differences in the railroad gauges hampered the movement, but most of the changes in gauge occurred at river crossings which had no bridges and the troops had to detrain at these points anyway.

Confederate cavalry raids, bent on destroying the railroad bridges and otherwise interfering with the reinforcing effort, imposed a more serious difficulty, but, except for delaying the latter part of the movement a few days, the raids were ineffective.

At the beginning of the siege, the Union Army had large supply trains in good condition and transporting supplies seemed feasible. Butearly in October rain began to fall and the roads became almost impassable. To make the situation more critical Bragg sent Wheeler to harass and destroy the Union supply trains as they moved over Walden’s Ridge on their trips to and from Bridgeport. Wheeler destroyed hundreds of wagons and animals and it was not long before the Union soldier received less and less food. Wagon horses and mules and artillery horses were on a starvation diet and many died each day.

Command of the two hostile armies had undergone a considerable change during the siege period. Grant received orders to meet “an officer of the War Department” at Louisville, Ky. He proceeded by rail to Indianapolis, Ind., and just as his train left the depot there, en route to Louisville, it was stopped. A message informed Grant that Secretary of War Stanton was coming into the station and wished to see him. This was the “officer” from the War Department who gave Grant command of the newly organized Military Division of the Mississippi. Thomas replaced Rosecrans. McCook and Crittenden had previously been relieved of their commands and their corps consolidated into the Fourth Corps under command of Granger. Stanton accompanied Grant to Louisville and there the two spent a day reviewing the situation.

In Bragg’s camp, Polk was relieved of his command, and Lt. Gen. William J. Hardee rejoined the army. Bragg’s army was reorganized into three corps commanded by Longstreet, Hardee, and Breckinridge.

When Grant reached Chattanooga on October 23 he found a plan already drawn up to open a new supply line for the besieged army. This plan of necessity was conditioned upon the terrain and the configuration of the river between Bridgeport, the railhead and base of supplies for the Union Army, and Chattanooga. (After the Tennessee River passes the city it flows southward for some 2 miles until it strikes Lookout Mountain where, after a short westerly course, itcurves northward. This elongated loop of the river is called Moccasin Bend.)

The plan called for 1,500 men on pontoons to float down the river from Chattanooga during the night of October 26-27 while another force marched across Moccasin Point to support the landings of the river-borne troops. Grant ordered the plan executed. The pontoon-borne troops quickly disembarked upon striking the west bank at Brown’s Ferry, drove off the Confederate pickets, and threw up breastworks. The troops marching across the neck of land came up to the east side of the ferry, joined this group, and constructed a pontoon bridge.

Hooker’s advance from Bridgeport coincided with this action. He marched by the road along Raccoon Mountain into Lookout Valley. There he met the advance post of a Confederate brigade and drove it back. Maj. Gen. O. O. Howard’s Eleventh Corps moved to within 2 miles of Brown’s Ferry, while Brig. Gen. John W. Geary of the Twelfth Corps remained at Wauhatchie to guard the road to Kelley’s Ferry.

The Confederates made a night attack against Geary which the latter repulsed, but both sides lost heavily. After this action, the short line of communication with Bridgeport by way of Brown’s and Kelley’s Ferries was held by Hooker without further trouble.

With the successful seizure of Brown’s Ferry and construction of a pontoon bridge across the Tennessee River there, and Hooker’s equally successful advance from Bridgeport and seizure of the south side of the river at Raccoon Mountain and in Lookout Valley, the way was finally clear for the Union Army to reopen a short line of supply and communication between Chattanooga and Bridgeport, the rail end of its supply line. This “Cracker Line” ran by boat up the Tennessee River from Bridgeport to Kelley’s Ferry. Above Kelley’s Ferry, the swift current made the stream unnavigable at certain points to boats then available. Accordingly, at Kelley’s Ferry, the “Cracker Line” left the river and crossed Raccoon Mountain by road to Brown’s Ferry. There it crossed the river on the pontoon bridge, thence across Moccasin Point, and finally across the river once more into Chattanooga.

Early in November, Bragg ordered Longstreet to march against Burnside in East Tennessee with Maj. Gen. Lafayette McLaw’s and Maj. Gen. John B. Hood’s Divisions of infantry, Col. E. Porter Alexander’s and Maj. A. Leyden’s battalions of artillery, and five brigades of cavalry under Maj. Gen. Joseph Wheeler—about 15,000 men in all. This movement caused great anxiety in Washington and the authorities urged Grant to act promptly to assist Burnside. Grant felt that the quickest way to aid him was to attack Bragg and force the latter to recall Longstreet. On November 7, Thomas received Grant’s order to attack Bragg’s right. Thomas replied that he wasunable to move a single piece of artillery because of the poor condition of the horses and mules. They were not strong enough to pull artillery pieces. In these circumstances, Grant could only answer Washington dispatches, urge Sherman forward, and encourage Burnside to hold on.

(See map on pages36-37.)

With the Confederate Army in front of Chattanooga divided into two corps, Hardee on the right and Breckinridge on the left on Missionary Ridge, and General Stevenson with a small force occupying Lookout Mountain, Bragg waited.

Grant’s plan of battle was for Sherman with his four divisions to cross the Tennessee River at Brown’s Ferry and march behind Stringer’s Ridge, concealed from the eyes of the Confederates, and take a position near the North Chickamauga Creek. He was to recross the river by pontoon bridge at the mouth of the South Chickamauga Creek, strike the north end of Missionary Ridge and capture it as far as the railroad tunnel. Thomas was to move his Army of the Cumberland to the left, and connect with Sherman. This united force was to sweep the Confederates southward off Missionary Ridge and away from their base of supplies at Chickamauga Station. Howard’s Corps was to act as a general reserve for this force. Hooker, with the Twelfth Corps and Brig. Gen. Charles Cruft’s Division (Fourth Corps), was to hold Lookout Valley. Col. Eli Long’s Cavalry was to cover Sherman’s left and when no longer needed for this task was to strike Bragg’s communications. This original plan, however, was changed several times to fit the situation.

The rains that hampered movement of Union supplies also delayed Sherman’s movement across the Tennessee. High water broke the bridge at Brown’s Ferry and Osterhaus’ Division could not cross the river. Subsequently it received orders to join Hooker in Lookout Valley.

On November 22, Grant received word that Bragg was withdrawing his army; actually the movement reported was Buckner leaving to reinforce Longstreet. To “test the truth” of the report, Grant changed his plans and ordered Thomas to make a demonstration to his front on the 23rd. This began the battles of Chattanooga.

The Union Army of the Cumberland had made its positions very strong during the time it was besieged by Bragg’s army. One of its strong points was Fort Wood on an elevated point east of the town. Thomas, according to instructions, sent Maj. Gen. Philip H.Sheridan’s and Brig. Gen. T. J. Wood’s divisions to level ground at Fort Wood and there formed them in line—Wood on the left, Sheridan on the right, with Brig. Gen. Absalom Baird supporting Sheridan. Brig. Gen. R. W. Johnson’s troops held the trenches, and Maj. Gen. O. O. Howard’s Corps, which had crossed from the north bank of the river, acted as the reserve.

At 2 p. m. on November 23, the lines of blue moved forward, driving the Confederate outposts and their supports back to the base of Missionary Ridge, and captured Orchard Knob, a low hill a little more than a mile in front of the ridge. The Union forces occupied thecaptured entrenchments and erected a battery on Orchard Knob. Except for occasional artillery firing, the fighting ended for the day.

Gen. Braxton Bragg

During the night of November 23-24, Sherman began to carry out his role in the drama. He selected Brig. Gen. Giles A. Smith’s brigade to man the pontoon boats, concealed in North Chickamauga Creek, to cross the Tennessee River and secure a bridgehead near the mouth of the South Chickamauga Creek. During the hours of darkness the brigade landed at its designated place. A few soldiers stopped at the mouth of the creek, surprising and capturing the pickets there. The remaining troops landed and prepared to build bridges across the Tennessee River and South Chickamauga Creek. By early afternoon they had finished the bridge across the river, and Sherman’s forces were across and ready to attack. Brig. Gen. Jefferson C. Davis’ Division (Fourteenth Corps), which had guarded the pontoons, also crossed and became part of Sherman’s force.

Sherman attacked and seized the north end of Missionary Ridge at 4 p.m. against only Confederate outpost opposition. To his surprise, Sherman found a deep and wide ravine separating the north end of the ridge from Tunnel Hill immediately southward, his real objective. Cleburne’s Division of Confederate troops had hurried to Tunnel Hill only an hour or two before Sherman seized the north end of Missionary Ridge, and they were busily engaged entrenching there when Sherman arrived across the ravine from them. Sherman did not attack Tunnel Hill that afternoon, but entrenched where he was.

While operations were in progress, east of Chattanooga, Hooker moved into action west of the town. The failure of Osterhaus’ Division to join Sherman resulted in another change of orders. A new plan for Hooker to take Lookout Mountain and descend into Chattanooga Valley replaced the original one of having him merely hold Lookout Valley and the route to Bridgeport. Hooker had three divisions in his force commanded by Brigadier Generals Peter J. Osterhaus, John W. Geary, and Charles Cruft, each from a different army corps. Geary was on the right at Wauhatchie, Cruft in the center, and Osterhaus near Brown’s Ferry. It was a unique team. One who was present wrote, “We were all strangers, no one division ever having seen either of the others.”

THE BATTLE OF CHATTANOOGANOVEMBER 23, 24, 25, 1863

The terrain that confronted Hooker’s command was rugged, steep, heavily timbered, and topped by a rocky cliff. At the northern end, at the cliff base and halfway up the mountain, was a bench of nearly level land. On it stood the Cravens Farm. At 8 a. m. on November 24 Hooker sentGeary’s Division, supported by a brigade from Cruft’s Division, to effect a crossing of Lookout Creek. The troops accomplished this with little opposition and Geary climbed the mountain until the head of his column reached the cliff. The division then moved to the left and proceeded northward toward the point of the mountain.

While Geary climbed the mountain, Cruft, with his force, moved farther down the valley toward the Tennessee River and seized a bridge over the creek. Osterhaus’ Division then crossed the stream at that point in the face of sharp skirmishing with Confederate defenders before the latter retreated up the mountain. The three Union divisions soon joined on a common line and, supported by Union batteries on Moccasin Point, steadily drove Walthall’s Confederate brigade around the point of Lookout Mountain to the Cravens farmhouse. By noon, Hooker’s forces were in possession of the farm but the Confederates made a stand beyond the Cravens house within prepared defense works, and were joined there by two brigades from the top of the mountain. Fog which covered the mountainside most of the morning became so heavy that by 2 p. m. it was almost impossible to see. This factor, plus a shortage of ammunition, caused Hooker to halt and consolidate his position. Later in the afternoon, Carlin’s brigade arrived with a resupply of ammunition.

During the night, General Stevenson withdrew the Confederate forces from Lookout Mountain and marched them to Missionary Ridge where they joined their comrades holding that sector of the line.

“The Battle Above the Clouds” was fought on the bench of land surrounding the Cravens house. There was no fighting on top the mountain. The romantic name given in later years to this action on the Union right was the result of the fog and mist which shrouded the mountain that day from observers below. It was not until the next morning that the 8th Kentucky Volunteers planted the Stars and Stripes on top of the bluff.

The decisive blow of the battle was at hand. Grant’s orders for the morning of November 25 were as follows: “Sherman was directed to attack at daylight. Hooker was ordered to move at the same hour, and endeavor to intercept the enemy’s retreat, if he still remained; if he had gone, then to move directly to Rossville and operate against the left and rear of the force on Missionary Ridge. Thomas was not to move until Hooker had reached Missionary Ridge.”

Sherman began his attack, as directed, just after sunrise. His troops attacked Cleburne’s Division frontally, but without success. All night the Confederates had worked at strengthening their position on Tunnel Hill which now formed the Confederate right. These field works gave good protection to Cleburne’s men from enemy fire. The stubbornly fighting Confederates held their positions against repeated attacks by superior numbers. This fight continued until 3 p. m., and is a notable example of the value to a greatly outnumbered defending force of field works on a good position. Some Union troops did make a lodgment on the slopes of Tunnel Hill in the afternoon, but a Confederate charge drove them off. Cleburne’s soldiers held the hill.

In the meantime, Hooker was in trouble—not with the enemy, but with Chattanooga Creek. He started for Rossville bright and early to get into position to strike Bragg’s left. Stevenson’s men, who had evacuated Lookout Mountain during the night, had burned the bridge across Chattanooga Creek and had done all they could to obstruct the roads that Hooker needed to march to Rossville. Hooker lost 3 hours building a bridge across the creek and it was late afternoon before his men took their places on Missionary Ridge.

From his post on Orchard Knob, Grant realized that Sherman’s attacks had failed to gain their objective and that Hooker had been delayed in reaching his assigned position. To relieve some of the pressure on Sherman, Grant ordered Thomas to move out against the Confederate center on Missionary Ridge.

The ridge that lay before the Union troops was rough and steep. It rose from 200 to 400 feet higher than the level ground at its base. Its steep slopes were broken by ravines, strewn with boulders, and dotted with stumps, the latter reminders of recently felled timber. The first line of Confederate breastworks was at the foot of the ridge. Some unfinished works had been built half-way up the slope. Finally, a third line of works was built on the natural, instead of the military, crest of the hill. Thus, Confederate fire from the crest could not cover some of the ravine approaches.

Four Union divisions—Baird, Wood, Sheridan, and R. W. Johnson, from left to right—started toward the ridge. The hard charging Union soldiers soon overwhelmed the gray defenders in the rifle pits at the base of the ridge. Scarcely halting, and generally without orders to continue, the men in blue charged up the ridge. They followed the retreating Confederates so closely from the rifle pits that the Confederates on the crest in many places hesitated to fire for fear of hitting their own men. It was not long before units of the Army of the Cumberland pierced the Confederate line in several places and sent Bragg’s veterans reeling in retreat down the east slope of the ridge toward Chickamauga Creek. Sheridan pushed forward in pursuit of the retreating army, capturing men, artillery, and equipment. Even though the Confederate center had disintegrated, Hardee held his position on the Confederate right until darkness, and then began his withdrawal with Cleburne’s Division covering the retreat. Bragg’s army crossed Chickamauga Creek during the night, carrying out a surprisingly successful retreat.

During the evening of the 25th, Grant issued orders to Thomas and Sherman to pursue Bragg. The next morning, Sherman advanced by way of Chickamauga Station, and Thomas’ troops marched on the Rossville Road toward Graysville and Ringgold. In the vicinity ofRinggold, Cleburne’s Confederates held a strong position on Taylor’s Ridge covering Bragg’s retreat. Cleburne’s men repulsed a Union attack, inflicting heavy casualties, until Bragg’s army had successfully withdrawn southward, and then they followed. Union troops then occupied Taylor’s Ridge. There the pursuit stopped.

This decisive Union victory raised the siege of Chattanooga.

The following tabulation of strength and casualties at the Battle of Chattanooga is based on Livermore’s studies:

Meanwhile, in East Tennessee, Burnside attempted to hold Longstreet in check by abandoning territory and skirmishing when necessary, but avoiding any serious fight. This took Longstreet farther away from Chattanooga and lessened his opportunity to assist Bragg. Burnside gained precious time by using these tactics. Grant’s plan was to “whip” Bragg and then help Burnside.

After Missionary Ridge, with Bragg in full retreat, Thomas prepared to send Granger’s Corps and detachments from other commands, about 20,000 men altogether, toward Knoxville. In addition, Sherman was to march along the Hiwassee River to protect Granger’s flank. Grant reports that upon “Returning from the front on the 28th, I found that Granger had not yet got off.... I therefore determined ... to sendhim [Sherman] with his command, and orders ... were sent him at Calhoun to assume command of the troops with Granger, in addition to those with him, and proceed, with all possible dispatch, to the relief of Burnside.”

Skirmishing was more or less continuous around Knoxville. Burnside followed the original plan of buying time by giving up ground and fell back toward Knoxville, withdrawing into the city during the night of November 16-17. Longstreet drew up before the city the next day, and on the 29th made his initial attack against the Union position at Fort Sanders. The assault was repulsed and before it could be renewed Longstreet received word of Bragg’s defeat on Missionary Ridge. The Confederate commander deemed it necessary to maintain a threatening position before Knoxville until the approaching Union relief columns were but a day’s march distant. On December 4, Longstreet began his retreat toward Virginia. Sherman arrived on the 6th, and preparations for the pursuit of Longstreet were soon under way. Burnside’s command moved out in pursuit of Longstreet’s force; Granger’s Corps became the garrison of Knoxville; and Sherman’s command returned to Chattanooga.

The battles around Chattanooga must be considered as ending in one of the most complete victories of the war. Bragg’s army was defeated, men and material captured, and the Confederates driven south. The mountainous defense line which the Confederacy hoped to hold had been pierced and large sections of it were in Union control. Chattanooga, the railroad center, was now in Union hands and the interior line of communication from this section of the Confederacy to Richmond, by way of Knoxville, was destined to remain in Union control for the remainder of the war. Not only Chattanooga, but Knoxville and the rich, food-producing East Tennessee section was lost to the Confederacy. With this came relief for the Union sympathizers in East Tennessee. Virtually all of Tennessee was now under Northern control.

The fortunes of war brought changes to both commanders. Bragg asked to be relieved from his command and went to Richmond to become military advisor to Jefferson Davis. President Lincoln promoted Grant, in March 1864, to command of all Union armies in the field. Grant then left Chattanooga for the East, to lead the attack against General Lee in Virginia.

In the spring of 1864, the Union armies began to move into the heart of the Confederacy. Grant attached himself to the Army of the Potomac (General Meade) and began operations against Lee; Sherman moved against Gen. Joseph E. Johnston in Georgia.

The Army of the Potomac launched a campaign against Richmond. In the bitter battles of the Wilderness and Spotsylvania Court House, in May 1864, Grant reduced Lee’s offensive power. After being repulsed at Cold Harbor, Grant moved against Petersburg and a 10-month siege finally forced Lee to evacuate the city. Lee moved westward to Appomattox Court House where on April 9, 1865, Grant forced him to surrender.

While Lee and Grant fought it out in Virginia, Sherman, using Chattanooga for his base of supplies, conducted a strenuous campaign against the Army of Tennessee, first under Johnston and then Hood, finally entering Atlanta on September 2. In November, Sherman began his famous “march to the sea,” reaching Savannah in late December. From there he struck northward through the Carolinas and forced the surrender of Joseph E. Johnston’s army on April 26. By June all isolated Confederate forces had laid down their arms.
