10th Kentucky Infantry Regiment

The 10th Kentucky Infantry Regiment was a three-year volunteer infantry regiment that served in the U.S., or Union Army during the American Civil War.

Service
Early in 1861, John Marshall Harlan. moved from Danville to Louisville Kentucky. When the military companies were raised for defense of the city in the spring of that year, Harlan was captain of the Crittenden Union Zouaves. This company, under Harlan, proceeded to Muldraugh's Hill, September 17, when the volunteers were sent there under BGENs Sherman and Rousseau.

Ten days later, on Saturday, September 27, 1861, Harlan began raising a regiment. The ten companies were recruited quickly, and the regiment was at full-strength and in camp in Lebanon, Kentucky, by the end of October, 1861. On Friday, November 21, MAJ William Henry Sidell mustered it in for a three-year enlistment under Harlan's command.

The 10th were armed with 900 .69 and .71 caliber Prussian muskets. These muskets were able to fire the same ammunition as the M1842 Springfield smoothbore. The regiment trained and organized itself at Lebanon, Kentucky from the mustering date until the New Year. It was at once assigned to BGEN George H. Thomas's 1st Division in MGEN Don Carlos Buell's Department of the Ohio. The brigade to which it was assigned was COL M. D. Manson's 2nd Brigade.

1862
On the 31st of December the regiment left Lebanon and marched through Columbia to the field of active operations, moving east to stop the ongoing Confederate invasion of eastern Kentucky. Due to the terrain and the numerical superiority of the Confederate cavalry in the theater as well as secessionist sympathies of a large minority of the region, the commander of the U.S. forces in this theater would have to dedicate a large portion of his force to guarding the lines of communication and supply for the U.S. Army operations in small garrisons and small escorts. Due to this, the regiment would see most of its service the next year in this function operating in proximity but separated from the main Union forces.

Mill Springs
This movement by Thomas culminated in the Battle of Mill Springs, or Logan's Field as it was also called, January 19, 1862. The regiment was serving as supply train escorts while the rest of the 2nd Brigadehelped win at Mill Springs. Although ordered forward to rejoin the army on 17 January, the 10th's reunion with its brigade was slowed by impassably muddy roads. Arriving after the Rebel retreat had begun, the 10th was sent in pursuit. On Monday, January, 20, the 10th and the 14th Ohio were the first troops into the hastily evacuated Confederate fortifications where they captured a dozen pieces of artillery and large amounts of arms and equipment.

The victory at Mill Springs was followed soon after by the fall of Forts Henry and Donelson, and the Confederate retreat from Kentucky. From Mill Spring the 10th marched to Louisville. From Louisville it went by steamboat down the Ohio, and up the Cumberland to Nashville, and from Nashville it marched to Pittsburg Landing arriving after the Battle of Shiloh. It accompanied an expedition up the Tennessee river on transports to Chickasaw, where the troops landed and penetrated the country to destroy a railroad bridge east of Corinth and near Iuka, which was successfully done.

Buell's campaign
The 10th was with the troops in the advance upon Corinth, and took part in all movements of that campaign. In the organization of the army April 30, 1862, it was in BGEN S. S. Fry's brigade of Thomas’ division. . The 10th Kentucky spent May in the Siege of Corinth. After the capture of Corinth, the 10th moved into Alabama and spent June through August in Buell's Campaign in Northern Alabama and Middle Tennessee that eventually threatened the important Rebel transportation hub of Chattanooga.

In Buell's campaign, in July, the 10th garrisoned the town of Eastport, MS. It also crossed the river at Eastport, and marched with trains to Florence, AL. On Friday, July 25, two companies (A and H) were posted to guard Courtland bridge, and while there a large force of Confederate cavalry under Gen. Armstrong fell upon them and captured them. COL Harlan, in his report of this affair, written August 8 at Winchester, Tenn., states that he had received a brief note from Capt. Henry G. Davidson, who was in command of the two companies, in which Capt. Davidson shows that when the enemy appeared he had his men behind the railroad embankment, and fought until he was surrounded. He says his men behaved splendidly, fighting till the last moment. He compliments especially Capt. Pendleton and LTs Reynolds, Barry and Shively; several of his men were wounded, and eleven of the enemy were killed and more than twenty wounded. Col. Harlan says the enemy was greatly enraged that the small body had fought so stubbornly, and denounced Capt. Davidson because he did not surrender. They fought until overpowered by numbers.

The officers in the command were taken to Tupelo, MS while the enlisted men were taken to Moulton, MS where they were paroled. On parole, they were sent to Nashville and then Camp Chase in Ohio until September 6, 1862, when both officers and men rejoined the 10th.

Bragg's invasion
The Confederacy wanted to relieve the pressure on Vicksburg and Chattanooga, so Braxton Bragg decided to invade Kentucky hoping to reclaim it for the rebellion. The 10th Kentucky had garrisoned Winchester, Tennessee for the month of August when it joined Buell's army marching to Kentucky to oppose Bragg.

The first indication that something was happening came in late June when Col. Phil Sheridan, in the Army of the Tennessee, reconnoitered Tupelo and found that the Confederates had abandoned their camp and begun moving towards Chattanooga, while Sterling Price was gathering another Confederate army in Mississippi. Several captured letters from Confederate soldiers boasted that the Yankees would be given the slip (Maj. Gen William Rosecrans was impressed with Sheridan's foray and recommended him for promotion to brigadier general).

The Rebels' plan was to have Price and Bragg unite and push the Confederacy's northern border to the Ohio River. Once the two Confederate armies were combined, Bragg's would command. Assuming that Buell's army could be destroyed, Bragg and Smith would march north into Kentucky, a movement they assumed would be welcomed by the local populace. Any remaining Federal force would be defeated in a grand battle in Kentucky, establishing the Confederate frontier at the Ohio River. The campaign plan needed perfect coordination between multiple armies initially without unified command. Bragg almost immediately began to have doubts despite President Davis' pressure to take Kentucky. Smith quickly abandoned the agreement, opting for a solo adventure that he thought would bring him personal glory. Deceiving Bragg as to his intentions, he requested two more brigades for his move to Cumberland Gap, yet, on Saturday, August 9, told Bragg that he was breaking the agreement and bypassing Cumberland Gap. Unable to command Smith to honor their plan, Bragg focused on a movement to Lexington instead of Nashville, warning Smith that Buell could pursue and defeat his smaller army before Bragg's army could join up with them.

Smith marched north with 21,000 men from Knoxville on Wednesday, August 13; Bragg departed left Chattanooga two weeks later on Wednesday, August 27, just before Smith reached Lexington. The beginning of the campaign coincided with Lee's offensive in the northern Virginia campaign (second Manassas campaign) and with Price's and Van Dorn's operations against Grant. Although not centrally directed, it was the largest simultaneous Confederate offensive of the war.

In reaction, Buell was forced to abandon his slow advance toward Chattanooga and concentrate his army around Nashville, however, news that Smith and Bragg were both in Kentucky convinced him of the need to place his army between the Confederates and the Union cities of Louisville and Cincinnati. On Sunday, September 7, Buell left Nashville and began racing Bragg to Louisville.

The capture of a Union fort at Munfordville, distracted Bragg making him choose whether to continue toward Louisville or rejoin Smith, who controlled the center of the state by capturing Richmond and Lexington, and threatened to move on Cincinnati. Bragg chose to rejoin Smith.

Buell reached Louisville, where he gathered, reorganized, and reinforced his army with thousands of new recruits. He dispatched 20,000 men under Brig. Gen. Joshua W. Sill toward Frankfort, hoping to distract Smith and prevent the two Confederate armies from joining against him. Meanwhile, Bragg left his army and met Smith in Frankfort, where they attended the unelected inauguration of Confederate Governor Richard Hawes on October 4. The inauguration ceremony was disrupted by the sound of cannon fire from Sill's approaching division, and organizers canceled the inaugural ball scheduled for that evening.

The Rebel invasion culminated in the costly Union victory at Perryville. The 10th had made the long march to Louisville, and in the organization of the army at the time of the battle of Perryville the 10th was in the Gilbert's III Corps, Schoepf's division, Fry's brigade, being brigaded with the 4th Kentucky, 10th and 74th Indiana and 14th Ohio. On Wednesday, October 8, 1862. At the time of the battle, the 10th commanded by LTCOL Hays in Fry's 2nd Brigade did not become engaged in the battle, but when Bragg failed to follow up MGEN Polk's success, the brigade was part of the pursuit of the Rebels of the state and then marched to Gallatin, Tennessee, twenty miles northeast of Nashville on the north side of the Cumberland River.

Army of the Cumberland
Although Perryville was a strategic victory for the Union, Buell was subsequently relieved for failing to destroy the Bragg's invading army, and MGEN William S. Rosecrans was appointed to command the Army of Ohio and the Department of the Cumberland.

The Army of Ohio's main force was XIV Corps, further divided into three wings: Thomas' Center, Crittenden's Left, and McCook's Right. Thomas and McCook were West Pointers, but Crittenden was a political general from a highly influential Kentucky family. Rosecrans also brought MGEN David Sloane Stanley, another academy man, to take charge of his cavalry. He subsequently renamed his forces the Army of the Cumberland with the mission of restoring Middle and East Tennessee to U.S. control.

First, Rosecrans needed to retrain, reorganize, and resupply his army into fighting condition. Although the army was considered seasoned and veteran having been in three major engagements, none of its commands had been engaged in all of them, and some not at all. Armaments were a wide variety with many smoothbore muskets still in the use, morale was low, some units were unpaid for six months, it had many incompetent officers, some cavalry were still unhorsed and unarmed, and mail delivery was poor. The army, numbering 67,000 men on paper, only had 40,000 combat-ready men. The precarious supply situation was caused by the more numerous Confederate cavalry constantly attacking and severely damaging the Louisville & Nashville Railroad, which would not be restored until November; and the Cumberland River was so low that most vessels could not navigate it as far as Nashville. With many regiments of the army serving garrison duty, any advance would have to wait until sufficient supplies were available. To mount an offensive campaign, Rosecarns needed to solve all these issues.

The 10th Kentucky welcomed the change in leadership, as Buell had never been popular. When Rosecrans arrived, one newspaperman noted that "the army threw up its hat in delight." Colonel Benjamin Franklin Scribner thought Rosecrans impressed the troops "by his open and genial manner, contrasting agreeably with the taciturn exclusiveness of ... Buell." Rosecrsans worked hard at refitting his army. He was in frequent communications with Secretary of War Stanton, and General-in-Chief Henry Halleck for more arms, and in recognition of the size and terrain of his theater, more cavalry, but he received little from them save Stanton's dislike. As Rosecrans reorganized the army, resupplied it, and solved pay problems, morale in the 10th Kentucky and the new Army of the Cumberland rose.

Stones River campaign
Two months after assuming command, with the army ready for field service once again, the Army of the Cumberland's was ready. When he was ready, Rosecrans advanced from Nashville to Murfreesboro. This offensive, a multi-pronged advance against Bragg, would result in the Battle of Stones River, fought from December 31, 1862, and January 2, 1863.

In November as part of Rosecrans' reorganization, BGEN Fry replaced Gilbert as the commander of the 3rd Division. In turn, COL Harlan assumed command of the brigade as the senior regimental commander and LTC Hays took command of the regiment. Through November and into December 1862, Harlan was tasked with maintaining lines of supply and communication in central Tennessee. Operating out of Castalian Springs, TN, Harlan sent Hays and the 10th to garrison Hartsville, TN. Soon, the 39th Brigade of the 12th Division replaced the 10th who returned to Castalian Springs.

On Sunday, December 7, 1862, the brigade marched fifteen miles east to Hartsville, in reaction to Morgan's attack there where his 4,000 man force captured the 1,800 man garrison. They reached the battlefield in time to observe the last of Morgan's troops, but too late to rescue the captured garrison. They arrived in time to save much property, including several hundred guns and a large amount of cartridges. These arms were un-issued imported British Pattern 1853 rifles. Since the 10th had "arms which were, in many respects defective, and in some respects entirely useless", the men of the regiment turned in their smoothbore muskets to the supply officers and replaced them with the new .58 caliber Springfields which extended their firepower to several hundred yards.

While the Army of the Cumberland was on the Stones River Campaign, the 10th was sent north on Tuesday, December 21, into Kentucky to chase down Morgan who had raided deep into the state. Morgan was targeting the Louisville & Nashville (L&N) Railroad at Muldraugh Hill, KY. The regiment rode the railroad from Gallatin to near Munfordville, from where they force-marched through Elizabethtown in time to catch Morgan's force on the Rolling Fork River, Monday, December 29 near Lebanon Junction. This area was home to many of the men in the regiment. Despite being slightly outnumbered by Morgan's force, the brigade was concentrated and Harlan effectively used it to surprise Morgan's scattered cavalry and drive them off.

The 10th remained in Gallatin into January 1863.

1863
The men of the 10th spent the winter and spring of 1863 based in and around the Army of the Cumberland's base at Murfreesboro. The regiment continued to gain experience escorting logistics trains and fending off both regular and irregular Rebel cavalry raids. The regiment saw the departure of its commissioning commander, COL Harlan, who resigned due to his father's death and family commitments. As a member of the Army of the Cumberland, the 10th would spend 1863 in Eastern Tennessee and Georgia as part of the U.S. plan to liberate the region and control the important rail hub of Chattanooga to greatly complicate the Confederacy's logistical support to their war effort.

The Tullahoma campaign
In the Tullahoma campaign, the 10th was in the 2nd Brigade (BGEN Steedman)of the 3rd Division (BGEN Brannan) of MGEN Thomas' XIV Corps. The Tullahoma campaign was marked by rapid movement by the Army of the Cumberland facilitated by its increased cavalry and added mounted infantry such as Wilder's Lightning Brigade despite heavy rains that muddied the roads. XIV Corps advanced on 24 June to seize Hoover's Gap. Wilder outstripped the rest of XIV Corps (including the 10th that was bogged down in heavy rain and muddy roads at the rear of the corps' line of march). When Wilder surprised the Rebels and drove them through the length of the gap, he disobeyed his orders to hold his position at initial contact to wait for the rest of the corps. Instead, he took up defensive positions on the far southeastern entrance of the gap and with his overwhelming firepower due to his new Spencers, held off Confederate attempts to retake the gap until reinforced by oncoming elements of the corps. As such, the XIV Corp advance was so slowed by the rains that the 10th and its brigade arrived at the gap on 25 June in the afternoon and were ordered through to Garrison's Creek ten miles to the south to turn the Rebel left flank. The 10th saw some light skirmishing on the right flank as the Rebels were repulsed in their own attempt at flanking the 3rd Division's left flank. The 10th pushed forward the next day and by the 3rd of July, the Rebels had fled Tullahoma. In the action,the 10th Kentucky lost one man.

The Chickamauga campaign
Through the summer, the 10th pulled back to garrison various locations that had been abandoned by the Rebels in middle Tennessee until August 16, when it rejoined the army. On that date, Rosecrans launched his campaign of maneuvering to force Bragg out of Chattanooga without a pitched battle. It worked brilliantly. The 10th, now part of COL Croxton's 2nd Brigade of Brannan's 3rd Division of XIV Corps, moved across the Tennessee near the mouth of Battle Creek fifteen miles upstream from the rest of XIV Corps toward Chattanooga. Brannan's division crossed the river with 1st Brigade (COL Connell) on August 29, but they encountered no opposition as they swam the river, pushing their bundles of clothing and equipment on logs or other pieces of wood in front of them. After they had ensured that there were no Rebels around the crossing point, on 31 August, COL Van Derveer's 3rd Brigade, the three divisional artillery batteries, and the 10th, within Croxton's 2nd Brigade, swam and rafted across. Once across, it concentrated with the rest of XIV Corps near Trenton, Georgia in position to move through Stevens' Gap to pursue Bragg's army.

After Negley's 2nd Division of XIV Corps fought with Cleburne's Division of D. H. Hill's Corps at Davis's Cross Roads on September 11, 1863, the Army of the Cumberland hurried to consolidate their vulnerable separated corps. The 10th began moving northeast toward Chickamauga Creek.

By 18 September, XIV Corps had moved northeast and was anchoring the Arm of the Cumberland's left at Lee and Gordon's Mill. As a result of delaying actions at Reed's and Alexander's Bridges across Chickamauga Creek, Rosecrans realized his left flank was exposed and Bragg was trying to get between him and his base at Chattanooga. Due to this XIV Corps was moved further north to Kelly's Field. The 2nd Brigade positioned on the right of Brannan's 3rd Division at the extreme left of the XIV Corps flank. Rosecrans had placed his reserve Corps under MGEN Granger two miles to the north of Thomas' XIV left end at McAfee's Church. The surviving men in the 10th were luckier than their comrades on the line. A cold front had come through and after a very warm day, the temperature dropped. The 10th were lucky to have fires. Those soldiers on or closer to the front line were could not light fires due to the close proximity of the two armies in the night.

The First Day
On the morning of 19 September, Brannan received word that Rebel cavalry from Forrest's Cavalry Corps had been separated from the main enemy body in the woods between Reed's Bridge and Alexander's Bridge Roads. The regiment received the word to fall in while they were still making their coffee and were a little disgruntled at having to eat on the move. As the 2nd Brigade moved forward to contact, the 10th in the second line was shifted to the extreme left of the brigade where it drove off Davidson's Cavalry Brigade of Pegram's Division under Forrest. The brigade was soon attacked by infantry from Walker's Reserve Corps. On the right of the brigade, the 74th Indiana found its right being outflanked by Rebels. Croxton pulled the 10th from the other end of the brigade line at the double-quick to shore up his right. The 10th passed through and behind the 74th and face perpendicular to the original line catching the Rebels in the right flank and stopping them. The 74th regrouped and took the end of the right flank so that the brigade now formed an "L" shape in the woods with the 10th, 14th Ohio, and 74th in the stem and the 4th Kentucky and 10th Indian in the foot. In this position, the brigade fought fiercely resisting all Rebel attempts to shift it until they ran out of ammunition just before noon. BGEN John King's brigade of U.S. Army regulars relieved them.

The action had been quite heavy and Company B was in the thick of the fighting, losing more than twenty men in one hour of fighting the woods. The whole brigade withdrew a half mile out of the woods to La Fayette Road to replenish their ammunition. Once re-armed, they moved back to engage the enemy joining their division on its northern, left flank just to the right of Baird's 1st Division which was the new XIV left flank. Their new position was on the crest of a ridge a quarter-mile west of their original position in the woods.

Once again, the brigade repulsed attempts by Walker's Corps to break the Army of the Cumberland's line. By 14:00, they had again fired away all their ammunition, as had the rest of their division. This time, they were relieved in the line by Johnson's 2nd Division of McCook's XX Corps, and received direction from Brannan to withdraw west of La Fayette Road at the foot of Horseshoe Ridge to resupply.

While the division was resupplying, Baird's 1st Division was being steadily pressed back. By the time King's 3rd Brigade reached Brotherton Filed just east of La Fayette Road, it was flanked, overwhelmed and broke. Initially alerted, the 10th were kept below horseshoe ridge as Thomas chose the 92nd Illinois Mounted Infantry which had been detached from Wilder's Lightning Brigade in Reynolds'4th Division to act as a Corps quick reaction reserve. While the 10th looked on, the 92nd, three companies of whom were completely armed with Spencer rifles, successfully stopped the Confederates with their superior firepower.

It was by now 16:00, and the 10th were kept at the foot of the ridge as an ad hoc reserve. The regiment had just fought their first "real" battle and had acquitted themselves well. It moved further south back towards Lee & Gordon's Mill where it spent the cold night. The survivors in the 10th mates were luckier than their comrades on the line. A cold front had come through and after a very warm day, the temperature dropped. The 10th were lucky to have fires. Those soldiers on or closer to the front line were could not light fires due to the close proximity of the two armies in the night.

The Second Day
At 03:00, on the morning of 20 September, the 10th Kentucky moved northeast with his regiment back to the ridge crest they had occupied the prior afternoon. All along the line, Federal troops were building ad hoc breastworks. After occupying the position for three hours, at 07:00, they were moved further left (North) so that they were on the right of the brigade on the left of the division.

At 09:00, the Rebels attacked. Initially, the 10th's foes were Stewart's Division of Buckner's Corps, and the Kentuckians held them at bay. Unknown to them, Rosecrans' misread of the tactical situation around 11:00 led to a gap opening in the Federal line at the other end of their division's line. Also, during the night, Bragg had reorganized his army into two wings under LTGEN Polk (right) and LTGEN Longstreet (left, including finally all of his command from Virginia), and at 11:00, an attack column of Longstreet's veterans from the Army of Northern Virginia hit the gap and broke through the Federal line. The column under command of MGEN Hood poured through and caught Federal troops out of position on the march north from McCook's XX Corps to reinforce Thomas. As well as Stewart's troops to their front, the regiment soon had Law's Division flanking their right. As the other brigades in the division began to give way under the onslaught, Col Croxton ordered the brigade to fall back to Horseshoe Ridge. Executing a fighting withdrawal, the 10th was pushed back with the rest of the division to the crest of the ridge by the Snodgrass House.

On the ridge, the 10th, although having suffered heavy casualties, regrouped and replenished their ammunition which had almost run out during the withdrawal. The whole brigade was kept in reserve behind the developing Federal line on the ridge for the moment. While the Army of the Cumberland's right was collapsing and reeling back along the roads toward Chattanooga, Brannan kept a cool head and faced his division southeast at the foot of Horseshoe Ridge. After a brief respite, at 11:30, he called Croxton to bring his brigade back into line. The regiment was brought forward and place in line next to some artillery that formed below the ridge at the northern edge of Poe Field just inside the trees.

The brigade built breastworks again of whatever material they could find. The Army of Northern Virginia veterans kept coming in greater numbers. The 10th's brigade were soon hotly fighting BGEN Robertson's Arkansans and Texans as first, COL James L Sheffield's Alabamians, and then BGEN Benning's Georgians crossed the southern end of Poe Field below the brigade, presenting their right flank. The artillery opened fire to great effect. While Sheffield continued west pursuing the broken Federals, Benning turned to face Croxton's brigade, and attacked north across the field to add to the weight of Robertson. The action grew even hotter for the men of the 10th as it neared noon.

At this point of the battle, Croxton was wounded and the 10th's commander, COL Hays, had to assume command of the brigade. The 10th and the rest of the brigade broke under the weight of the two brigades attacking them and fell back in disarray up Horseshoe Ridge where the rest of XIV Corps and odd lots from XX and XXI Corps were forming a new line. On the crest Hays was busy restoring order to the 14th Ohio and 4th Kentucky who had broken and streamed west to the ridge. Meanwhile, the 10th's new commander, LTC Wharton managed to rally the surviving members of the regiment. Hays joined the 10th with the 10th and 74th Indiana and withdrew orderly north into Reynolds's division on Snodgrass Hill.

Brannan was organizing the units from his shattered division along the heavily wooded ridge. Brannan, with the assistance of COL Walker and future congressman BGEN John Beatty (who had assumed command of the division from MGEN Negley who suffering from dysentery and exhaustion was rendered completely ineffective) managed to construct a line along the ridge from the remnants of his and Negley's divisions. The 10th found themselves ordered to the middle, highest of three crests of Horseshoe Ridge. By 12:45, the regiment was in a new Union line that was holding their position.

Brannan and the regiment fought on against the Rebel onslaught against Thomas' position holding Snodgrass Hill which now included some brigades and divisions from XX and XXI Corps. The remainder of the Army of the Cumberland had dissolved to the point that the only cohesive, intact unit remaining south of the 10th and the rest of Thomas' command was Wilder's which had seriously mauled the left flank of Longstreet's attack column due to the firepower.

From mid-afternoon to dusk, the Kentuckians of the 10th were in the midst of Thomas' Snodgrass Hill/Horseshoe Ridge line as the Rebels continuously attacked. Starting about 16:30, Longstreet committed his last reserve, Preston's division to the battle, which made several attempts to assault Horseshoe Ridge As the Confederates saw the Union soldiers withdrawing, they renewed their attacks, threatening to surround Johnson's and Baird's divisions. Although Johnson's division managed to escape relatively unscathed, Baird lost a significant number of men as prisoners. Thomas left Horseshoe Ridge, placing Granger in charge, but Granger departed soon thereafter, leaving no one to coordinate the withdrawal. Maqttingly and the 10th managed to stealthily withdraw to the north with the rest of Brannan's division. Eventually all divisions managed to escape due to the sacrifice of three regiments—the 22nd Michigan, the 89th Ohio, and the 21st Ohio—who were left behind without sufficient ammunition, and ordered to use their bayonets. They held their position until surrounded by Preston's division, when they were forced to surrender.

Aftermath
Brannan's troops withdrew to positions around Rossville Gap during the night. Garfield met him Thomas in there and relayed to Rosecrans that "our men not only held their ground, but in many points drove the enemy splendidly. Longstreet's Virginians have got their bellies full." Although the troops were tired and hungry, and nearly out of ammunition, he continued, "I believe we can whip them tomorrow. I believe we can now crown the whole battle with victory." The two urged Rosecrans to rejoin the army and lead it, but a defeated Rosecrans remained in Chattanooga.

The Army of Tennessee camped on the battleground for the night, unaware that the Union army had slipped from their grasp. Bragg was not able to mount the kind of pursuit due to his army's exhaustion, the fact that Longstreet's divisions had arrived by rail without wagons to transport their supplies, and the high loss of the artillery horses injured or killed during the battle. Bragg also had no pontoon bridges to effect a crossing of the Tennessee. Bragg paused at Chickamauga to reorganize and gather equipment lost by the Union army. Although Rosecrans had been able to save most of his trains, large quantities of ammunition and arms had been left behind.

The 10th Kentucky withdrew from Rossville Gap with the rest of the Army of the Cumberland withdrew to the former Confederate fortifications around Chattanooga to build a strong defensive line. However, by doing so, Rosecrans yielded the surrounding heights to Bragg putting his supply lines into Chattanooga at risk. The Confederates soon occupied Lookout Mountain and Missionary Ridge and laid siege upon the U.S. forces.

The comrades of the 10th had survived their biggest battle yet.

The Chattanooga campaign
Bragg, with a larger army than Rosecrans, was strongly fortified to the east, south, and west of Chattanooga. His positions commanded the river below. Practically the Army of the Cumberland was besieged. The Rebels, with Joseph Wheeler's cavalry roaming north of the Tennessee River, was frequently interrupting the Army of the Cumberland's supplies. Longstreet's corps holding Lookout and Raccoon mountains west of Chattanooga, commanded the railroad, the river, and the shortest and best wagon roads both south and north of the Tennessee, between Chattanooga and the railhead at Bridgeport (even the road that ran along the north bank of the river), a distance of twenty-six miles by rail.

Due to this situation, all supplies for Chattanooga had to be hauled by the Anderson road, a circuitous route, north of the river, over mountainous country, increasing the distance to over sixty miles. The region along the road became so exhausted of food for the cattle that by the time they reached Chattanooga they were in as bad condition as the animals already there. Nothing could be transported but food, and the army were without sufficient shoes or clothing for the coming winter. There was a single supply line open that snaked nearly 60 miles over rough terrain from Bridgeport, Alabama to the north, across rough terrain to the east, and came down to the city from the north. Supplying an army during good weather on this road was an ordeal, even with the mule teams in good condition, but with the rainy season that soon set in, and the incessant hauling wearing out the mules, the army's daily rations were constantly dwindling. The unpaved road was significantly worsened by heavy autumn rains that began in late September.

Starting with a tropical storm from September 28 to October 1, the besieged garrison endured eighteen periods of significant rainfall until the end of October. Twelve to eighteen inches of standing water were reported in the trenches of Chattanooga's defenses. As the ordeal continued, the 10th Kentucky saw on average 20 percent of the army reported sick on any given day of the siege. The large number of army horses and mules in the city generated 570,000 pounds of manure daily. Forty-thousand gallons of urine per day soaked encampments and contaminating sources of water. Disease, filth, and contamination were everywhere. The siege induced acute malnutrition also increased vitamin-induced disease rates. Toward the end of October, the army's typical rations were "four cakes of hard bread and a quarter pound of pork" every three days. While the army's rations were limited, the cavalry and mounted infantry were able to get out to forage vigorously to supplement rations and replenish their horses as well as bringing back forage for the supply train.

Due to Rosecrans' preparations and stocking of supplies in Chattanooga prior to Chickamauga, the men of the 10th did not really feel the effect of short rations, but many of their horses and mules died due to lack of forage. On October 2, Wheeler made a devastating attack on a ten-mile long Union wagon train. This loss in wagons, with the roads becoming almost impassable by reason of the heavy rains and the growing weakness of the animals, lessened daily the amount of supplies brought into the town, so that suddenly, the long term survival of the horses and mules was in serious doubt. This was what Bragg was quietly waiting for. To supply an army some forty thousand strong, by wagon transportation over rough mountain roads a distance of sixty miles, Bragg thought was an impossibility, and that unless other lines were opened up, the city would be his at minimum cost.

As the siege set in, Rosecrans reorganized his army to counter the losses from Chickamauga moving the 10th Kentucky to the 3rd Brigade of the 2nd Division of XIV Corps.

The United States high command began immediate preparations to relieve the city. Only hours after the defeat at Chickamauga, Secretary of War Edwin M. Stanton ordered Maj. Gen. Joseph Hooker to Chattanooga. On September 24, Joseph Hooker had been detached from the Army of the Potomac with the 2nd and 3rd divisions (Steinwehr's and Schurz's) of XI Corps and XII Corps. Hooker and his troops traveled, within twelve days, from the Army of the Potomac on the Rappahannock via the U.S. railroads to the Tennessee River at Bridgeport, without an accident or detention. Upon arrival, members of Hooker's command were stunned to see how hungry these units that made it out of Chattanooga were.

Even before the Union defeat, Maj. Gen. Ulysses S. Grant had been ordered to send his available force to assist Rosecrans, and it departed under his chief subordinate, Maj. Gen. William T. Sherman, from Vicksburg, Mississippi. On September 29, Stanton ordered Grant to go to Chattanooga himself via Louisville where he met Stanton and received command of the newly created Military Division of the Mississippi, bringing territory from the Appalachian Mountains to the Mississippi River under a unified command. On October 18 en route, he replaced Rosecrans with Thomas to command of the Army of the Cumberland. Grant arrived in Chattanooga on October 23.

While no longer acting with his former purpose and energy, before his relief, Rosecrans had begun developing a plan to reopen his supply lines with his chief engineer, Brig. Gen. "Baldy" Smith and Thomas. Grant met with Rosecrans at Stevenson rail junction after dark on October 21, where Rosecrans offered suggestions to relieve the siege including a plan to open a supply line down along the river. Grant wondered why Rosecrans had not implemented his own suggestions. After his debrief with Rosecrans, Grant's train then rolled on to Bridgeport.

Assessing the situation, Grant developed four courses of action:
 * 1) Opening supply lines to lift the siege.
 * 2) Amassing forces.
 * 3) Clearing the high ground
 * 4) Attacking Bragg

Opening supply lines
Thomas and Smith had continued the planning they started under Rosecrans. Once he was apprised of Thomas' plan to reopen the supply lines, Grant gave the go ahead. The plan was to establish a crossing on the Tennessee River and link up with Hooker's troops coming to the city. The crux of the operation was a three pronged attack that converge on Brown's Ferry. One prong would march across Moccasin point (on the U.S.-held north side of the river) and seize the east landing of the ferry. Another force would float down the river and land on the west landing. The third would be Hooker's force advancing up the railroad in Lookout Valley from Bridgeport.

Brown's Ferry
Brown's Ferry was opposite Moccasin Point where the road cut the foothills turning south to Wauhatchie Station and then west to Kelley's Ferry. There, they could establish a logistics head for Federal supply boats. Seizing Brown's Ferry and linking up with Hooker would create a reliable, efficient supply line (soon called the "Cracker Line"). In addition, a force at Brown's Ferry would threaten the right flank of any Rebel attempt to cut the line in Lookout Valley.

Braxton Bragg was unaware of planned operation but had heard from scouts of Hooker's pending river crossing at Bridgeport. Concerned about his left flank, he ordered Longstreet to move additional units into Lookout Valley, but, unknown to Bragg, the order was ignored. Furthermore, Longstreet's lack of diligence allowed command mix ups to leave only two regiments near Brown's Ferry. The Rebels held Brown's Ferry with Oates' 4th Alabama of Law's undermanned Brigade of Hood's Division of Longstreet's Corps. This was deemed a weak link to be exploited.

While the 10th brigade remained in the fortifications, Smith took two infantry brigades (Hazen's and Turchin's) and the army's Engineer Brigade (COL Stanley). On October 26, Turchin moved across Moccasin Point to hold the east bank at Brown's Ferry. At 03:00 on October 27, Hazen ferried his brigade in pontoon boats manned by Stanley's engineers Hazen's force slipped around Moccasin Point past the Lookout Mountain pickets. Using the river's current for swift movement, an early morning fog helped cover their movements. The landing was made at ferry landing's west side at 05:00 in relative silence allowing U.S. troops to come ashore, drive off the Confederate pickets, and immediately begin entrenching. By dawn, company guarded the ferry itself, with five companies nearby in reserve.

Oates, a capable veteran of the Eastern Theater, upon learning of the U.S. presence, immediately counterattacked but was beaten back. When Oates was wounded, his men lost their nerve and started retreating. Simultaneously, Stanley's oarsmen began to ferry Turchin's men across the river. Hazen and Turchin's combined force now outflanked the Confederates, who retreated to the south toward Wauhatchie. The Army of the Cumberland's first real fighting since Chickamauga was finished within a half-hour with a victory that lifted its spirits.

Oates had reported the landing of U.S. troops Law. His brigade commander blocked the road over Lookout Mountain with the rest of his brigade and reported the Union success to Longstreet. Longstreet dismissed the Union move to be only a feint and did not report it to Bragg as he was focused on a possible U.S. attack further to the southwest. When Bragg learned of it, he ordered Longstreet to retake the ground immediately, but Longstreet once again did nothing and Smith's men spent the day consolidating their bridgehead without interference. The pontoon bridge was completed by 16:30. Heavy rain returned late that evening and continued through the next morning, October 28.

Wauhatchie
The third prong, Hooker's column, at the same time, was advancing from Bridgeport, to reinforce Hazen if necessary. Hooker had left Maj. Gen. Henry W. Slocum with one of his divisions of to guard the railroad from Murfreesboro to Bridgeport while he sent Slocum's remaining division, under Geary, and Howard's XI Corps' two divisions to Lookout Valley. However, weather conditions delayed the movement, so Grant decided to move ahead with the Brown's Ferry operation even before Hooker could arrive.

Hooker's three Union divisions from Bridgeport by following the railroad via Shellmound and the Running Water Creek gorge. On October 28, after the rain had stopped, Bragg and Longstreet were having a conference on Lookout Mountain and while examining the U.S. position at Brown's Ferry, were interrupted by one of Longstreet's signal officers reporting the enemy advancing from Bridgeport. Turning to their left, they were astonished to see Hooker's column of 7,000 troops entering Lookout Valley. Due to his focus on further to the southwest, Longstreet's scouts had failed to detect Hooker's advance.

Hooker, while his force passed through Lookout Valley on October 28, detached Geary's division at Wauhatchie Station, a stop on the Nashville and Chattanooga Railroad, to protect the line of communications to the southwest as well as the road west to Kelley's Ferry. Meanwhile, Hooker's column marched through Lookout Valley and linked up with Hazen and Turchin at Brown's Ferry at 15:45, October 28. Thomas's staff began the preparations to bring supplies over the Cracker Line and he telegraphed General in Chief Henry W. Halleck that he expected "in a few days to be pretty well supplied". Once the line was open, "Hooker's dispositions were deplorable," with Howard's under strength XI Corps "bivouacked haphazardly" at Brown's Ferry. Worse, Geary's division, only 1,500-strong after detaching railroad guards, was posted in isolation.

Loathe to attack the entrenched forces at Brown's Ferry, Longstreet spotted Geary's troops at Wauhatchie. Miffed at missing the chance to the ferry, Bragg ordered Longstreet to attack Geary instead. There, Hooker had neglected to arrange his force into effective defensive positions, instructing them merely to find good cover for the troops and bivouac. He detached Brig. Gen. John W. Geary's division at Wauhatchie Station, a stop on the Nashville and Chattanooga Railroad, to protect his links to the south and west.

Amazed to see Geary's bivouacking soldiers with their large wagon train parked directly in front of him, Longstreet ordered Jenkins to crush Geary with an attack that night. While Law took his own and Robertson's brigades to block Hooker from Geary, Bratton took Jenkins's South Carolina brigade to attack Geary. Originally planned for 22:00, October 28, confusion delayed the attack until midnight. Geary and his officers, despite expecting an attack were surprised by its suddenness and formed into a V-shaped battle line, facing north and east.

Hearing the sounds of battle, the XI Corps quickly fell into ranks near Brown's Ferry. Hooker ordered Schurz to Wauhatchie Station to reinforce Geary. In the confusion, von Steinwehr got his division on the road first. Smith's brigade of Steinwehr's division was fired on by Law's Confederates, positioned on a 200 ft high blocking position above the road from Brown's Ferry. Smith climbed the hill to attack Law. Meanwhile, Hooker mistakenly deployed units from both XI Corps divisions against Law and Benning, leaving no one to go to Geary's aid. Law's outnumbered men held a strong hilltop position. In the darkness, Law repelled several vigorous assaults by Smith. After Law received some erroneous reports, he withdrew to Lookout Mountain, but as his men left their entrenchments, Smith's men spilled over them, capturing some stragglers and scattering a regiment that had not gotten the retreat order. Realizing no troops had gone to Geary, Hooker let Howard ride to Wauhatchie with some cavalry.

Geary continued to hold fast, though running low on ammunition, and just as Bratton began to sense victory, he received a note to retreat since Howard's relief force was arriving in his rear. Bratton also withdrew to Lookout Mountain, successfully covered by Benning's brigade. In the Wauhatchie fight, Bratton lost 356 men, while Geary's casualties numbered 216.

The lines open
In the city, the men of the 10th heard of the arrival of supplies as its news spread quickly. The Army of the Cumberland had held out and was now receiving reinforcements and supplies. U.S. losses in the battle were 78 killed, 327 wounded, and 15 missing. The Rebels reported their losses as 34 killed, 305 wounded, and 69 missing. One account says Bratton lost 408 men while Law lost only 52. Geary reported burying 153 Confederates and capturing over one hundred prisoners, so the Confederate losses may have been over 900 men. The Union forces now had its link to the outside and could receive supplies, weapons, ammunition, and reinforcements via the Cracker Line. Grant could now amass forces to take back the initiative from Bragg. The Army of the Cumberland would soon be one of three U.S. field armies in the city.

Badly needed clothing and equipment supplies began to flow in to the Army of the Cumberland. From October 28–30, skies cleared and roads began to show improvement easing the flow. By this time in late October many troops had no rations to eat for several days and foraged the countryside. Relieving troops claimed to see "half-famished" soldiers of the trapped army, but the men of the 10th and the rest of the Army of the Cumberland An added bonus was that in addition to opening an overland supply line of from Bridgeport to Chattanooga, the successful battle break the siege also opened the Tennessee River to logistic support from Bridgeport to Kelly's Ferry. Federals now controlled their line of communication.

The effect of the secure, reliable logistics support were such that Grant wrote: "It is hard for any one not an eye-witness to realize the relief this brought. The men were soon reclothed and well fed ; an abundance of ammunition was brought up, and a cheerfulness prevailed not before enjoyed in many weeks. Neither officers nor men looked upon themselves any longer as doomed. The weak and languid appearance of the troops, so visible before, disappeared at once. I do not know what the effect was on the other side, but assume it must have been correspondingly depressing. Mr. Davis had visited Bragg but a short time before, and must have perceived our condition to be about as Bragg described it in his subsequent report. ' These dispositions,' he said, ' faithfully sustained, insured the enemy's speedy evacuation of Chattanooga, for want of food and forage. Possessed of the shortest route to his depot and the one by which reinforcements must reach him, we held him at our mercy, and his destruction was only a question of time.' But the dispositions were not ' faithfully sustained', and I doubt not that thousands of men engaged in trying to ' sustain ' them now rejoice that they were not."

Amassing the forces
Even before he had taken command of the theater, Grant had been tasked to send help to Rosecrans. He detached Sherman and four divisions to go to Chattanooga. On October 3, they went upriver from Vicksburg to Memphis and then moved along the Memphis & Charleston Railroad. Grant tasked him to repair the rail line as he moved eastward. Due to the amount of repairs needed, it took six weeks before they arrived at Bridgeport. Grant dedicated the line from Memphis to supplying Sherman and realized that he needed more repairs done on the rail lines to Nashville to be able supply Thomas, Hooker, and even Burnside in Knoxville who had no functioning railways available. He directed Sherman to send men from Bridgeport up the line to Nashville to make these repairs.

The defeat at Wauhatchie angered Bragg who placed the blame squarely on Longstreet and wanted to relieve him. When he asked permission from Davis to do so, Bragg suggested sending Longstreet and his corps of 15,000 troops and Wheeler's 5,000 cavalry to Knoxville to attack Burnside there and threaten Grant's left flank. Longstreet objected for two reasons, he felt his force was not sufficiently larger than Burnside's 12,000 infantry and 8,500 cavalry, and because it would weaken the forces against the city just as the U.S. forces were increasing. On November 4, Longstreet left the lines around Chattanooga to go against Burnside.

With the supply lines open, Grant was able to run supplies by wagons over the road to keep the starvation of the Army of the Cumberland at bay. By the second week of November, through a combination of the wagons and boats coming up river, he was able to bring in twice the logistics needed to sustain the U.S. troops. The Army of the Cumberland had reinforced, but they were still far from ready for offensive operations. Grant planned on Thomas making a demonstration against Bragg's right flank the first week of November, but the still-weakened Army of the Cumberland was incapable of the endeavor. Thomas balked and suggested an attack on Bragg's left instead.

Thomas, Baldy Smith, and Brannan, now commanding the Army of the Cumberland's artillery conducted a reconnaissance on November 7 from the heights on the northern side of the Tennessee. Surprisingly, this expedition showed that the maps being used for planning were incorrect. They showed that he would need to move his artillery to support the attack. The party reported back to Grant that they would not be able to make the attack.

Grant was surprised by the intelligence, but Thomas suggested using Hooker's troops to clear Lookout Mountain to remove any threat to their supply lines. Grant accepted the suggestion and began re-planning their attacks. Grant and his staff assessed the situation and let the War Department know that nothing could be done to help Burnside until Sherman arrived.

For his part, Burnside, confident in his ability to defend himself, suggested that he pull all his forces between Chattanooga and Knoxville back to his fortifications in the city to draw Longstreet further away from his railhead at Loudon to make it more difficult for him to return to Bragg when Grant attacked. Grant thought it a good move and okayed the plan. He then made plans to attack once Sherman and his force were in town and rested.

As Longstreet had stopped at Loudon until Friday, November 13 awaiting orders. As he left that location midday Friday, his force threatened Knoxville, but he could not return quickly to Chattanooga. On Saturday, Sherman reached Bridgeport in person checking in with Grant that evening. On Sunday, November 15, Sherman and his troops reached Chattanooga.

Grant's operational plan was already prepared, save the dates, before Sherman's arrival. With Sherman's arrival, Grant would have forces twice as large as Bragg's army trying to besiege them, and he could put together a timetable for the operation. The Army of the Cumberland would play a supporting role in the upcoming actions with Sherman's Vicksburg veterans delivering a hammer blow on Patrick Cleburne's division on Bragg's right at the northern end of Missionary Ridge.

The last of Sherman's troops would arrive in the city Friday, November 20, so Grant planned on attacking the next day. As his plans went out to be implemented, the weather, specifically the rains upset the timetable. While the 10th Kentucky was re-equipping and getting back to full strength, Sherman's troops were being delayed by muddy roads and the fragility of the pontoon bridge at Brown's Ferry. Grant was forced to slide the schedule again to Monday, November 23. Although Grant had hoped to attack on Saturday, by Friday nightfall, November 20 only one of Sherman's brigades had crossed over Brown's Ferry and the attack had to be postponed. Grant was coming under increasing pressure from Washington to react to Longstreet's advance against Burnside at Knoxville.

Bragg, without his cavalry, lacked means of gathering intelligence and assumed that Sherman's corps would be heading toward Knoxville, not Chattanooga. Ergo, he expected Grant to fall on his left flank, Lookout Mountain. On November 12, Bragg placed Carter Stevenson in overall command for the defense of the mountain, with Stevenson's division placed on the summit. The brigades of Brig. Gens. John K. Jackson, Edward C. Walthall, and John C. Moore were placed on the "bench" of the mountain (a narrow and relatively flat shelf that wrapped around the northern end of the mountain approximately halfway to the summit). Thomas L. Connelly, historian of the Army of Tennessee, wrote that despite the imposing appearance of Lookout Mountain, "the mountain's strength was a myth. ... It was impossible to hold [the bench, which] was commanded by Federal artillery at Moccasin Bend." Although Stevenson placed an artillery battery on the crest of the mountain, the guns could not be depressed enough to reach the bench, which was accessible from numerous trails on the west side of the mountain.

Bragg weakened his position further on November 22, ordering Cleburne to withdraw his and Buckner's divisions from the line and march to Chickamauga Station, for railroad transport to Knoxville, removing 11,000 more men from the defense of Chattanooga. Bragg apparently believed, as Grant had hoped, Sherman was moving on Knoxville, which meant Longstreet would needed the reinforcements for which he had been constantly asking since he was first given the assignment.

Orchard Knob
On Monday, November 23, the 10th Kentucky saw columns of Cleburne's and Buckner's men marching away from Missionary Ridge and also heard claims from Confederate deserters that the entire army was going to retreat. Grant was afraid that Bragg would escape his grasp and that a reinforced Longstreet would become a viable threat to Burnside and Unionist East Tennessee, so he decided to disrupt the movement. He ordered Thomas to distract Bragg. Thomas sent Wood's3rd Division of Granger's IV Corps to advance in a reconnaissance in force, instructing him to avoid an engagement with the enemy and return to his fortifications when the strength of the Confederate line was revealed. The rest of Palmer's XIV Corps saw Wood's men assemble outside of their entrenchments. Their objective, approximately 2,000 yards to the east, was a small knoll 100 feet high known as Orchard Knob (also known as Indian Hill). Sheridan's 2nd Division lined up similarly to protect Wood's right flank, and Howard's XI Corps extended the line to the left, presenting over 20,000 soldiers arrayed in almost parade-ground alignment.

At 13:30, 14,000 Union soldiers moved forward at the double quick, sweeping across the plain, stunning the 600 Confederate defenders, who were able to fire only a single volley before they were overrun. Casualties were relatively small on both sides. Grant and Thomas decided to order the men to hold their position and entrench, rather than following the original orders to withdraw. Orchard Knob became Grant's and Thomas's headquarters for the remainder of the battles. Men of the Army of the Cumberland were elated at the success of their men.

Bragg readjusting his strategy, quickly recalling all units that were within a day's march. Cleburne's division returned after dark from Chickamauga Station, interrupting the process of boarding the trains to Knoxville. Bragg reduced the strength on his left to strengthen his now vulnerable right. He assigned Hardee to command his now critical right flank, turning over the left flank to Carter Stevenson. In the center, Breckinridge ordered his men to fortify the crest of Missionary Ridge, a task that Bragg had somehow neglected for weeks. Unable to decide whether to defend the base or the crest of the Ridge, the divisions of Bate and Patton Anderson were ordered to move half of their divisions to the top, leaving the remainder in the rifle pits at the bottom. Historian James L. McDonough wrote of the upper entrenchments, "Placed along the physical crest rather than what is termed the military crest ... these works severely handicapped the defenders."

Grant also changed plans as a result. Sherman had three divisions ready to cross the Tennessee, but the pontoon bridge at Brown's Ferry had torn apart and Osterhaus's division was stranded in Lookout Valley. After receiving assurances from Sherman that he could proceed with three divisions, Grant decided to revive the previously rejected plan for an attack on Lookout Mountain and reassigned Osterhaus to Hooker's command.

Lookout Mountain
Grant's battle plan of November 18 merely assigned Hooker the task of holding Lookout Valley. Six days later, however, Hooker had about 10,000 men in three divisions at his disposal, because Osterhaus's division could not cross the Tennessee due to disruption of the pontoon bridges. With Geary's and Cruft's (less one brigade) divisions, Hooker had too large a force to waste on guard duty. Thomas okayed a demonstration against the mountain, with the possibility of a full-scale assault. Hooker was ordered to "take the point only if his demonstration should develop its practicability." "Fighting Joe" ignored this subtlety and ordered Geary "to cross Lookout Creek and to assault Lookout Mountain, marching down the valley and sweeping every rebel from it."

While the advance of Cruft and Osterhaus demonstrated at Lookout Creek, Geary crossed the stream unopposed further south and found that the defile between the mountain and the river had not been secured. The Union troops were opposed by Brig. Gen. Walthall's brigade of Cheatham's division (temporarily under the command of Jackson). Geary swept northeast along the base of Lookout Mountain and pushed Walthall's completely outflanked and badly outnumbered men back to the Cravens House, just below the northern end of the mountain.

Brown's Rebel brigade on the mountain top were powerless to intervene in the battle raging below the cliffs. Geary's success allowed the other two divisions to cross the creek and push aside the Confederate skirmishers in front of them. Moore brought his Alabama brigade up around 13:00 to become embroiled in a fight with Geary and Whitaker's brigade of Cruft's division. Moore was pushed back and soon joined by Brig. Gen. Pettus's Alabama brigade.

By about 15:00, thick fog enveloped the mountain. Brig. Gen. Montgomery C. Meigs, quartermaster general of the Union Army, observing from Orchard Knob, was the first writer to name the action on Lookout Mountain the "Battle Above the Clouds". The two sides blazed away blindly in the fog the rest of the afternoon but few men were hit. During the fight, Hooker sent a stream of "alternate whimpering and blustering" messages to Grant, but got it exactly right when he predicted, "In all probability the enemy will evacuate tonight." Realizing the battle was lost, Bragg ordered the position abandoned. At midnight the fog cleared and, under a lunar eclipse, the divisions of Stevenson and Cheatham retreated behind Chattanooga Creek, burning the bridges behind them.

That night Bragg asked his two corps commanders whether to retreat or to stand and fight. Hardee counseled retreat, but Breckinridge convinced Bragg to fight it out on the strong position of Missionary Ridge. Accordingly, the troops withdrawn from Lookout Mountain were ordered to the right flank.
