The bloodiest 2 days of the Civil War. Rosecrans' planning was flawed, but
Thomas saved the Union army.
Bragg planned well enough, but some of his subordinate generals
(Polk and Hindman) betrayed him.

After the Tullahoma Campaign (23 June
- 3 July 63), Rosecrans
prepared his movement toward and around Chattanooga very carefully, all
the while exchanging acrimonious telegrams with Halleck who demanded that
he get moving. His
simple explanation that he had to wait for the corn crop to ripen, so that
he wouldn't have to carry with him the fodder for his animals, found no hearing
with generals insulated in Washington. As soon as his preparations were complete he crossed the Cumberland mountains and
sent Minty's cavalry part way to Knoxville and had Wilder
demonstrate opposite Chattanooga (thus binding two of Bragg's divisions)
in order to give the impression that he intended to cross the Tennessee
upstream. The impression was reinforced by Burnside's occupation of Knoxville
on 6 Sept. 63. As Rosecrans would then have been able to link up with Burnside,
this was the crossing which Bragg expected and was preparing for. However,
on 29 Aug. 63 Rosecrans' main force crossed the Tennessee downstream
from Chattanooga at 4 points in the vicinity of Bridgeport, Ala. He then sent the AotC in 3 groups on a 50 mile wide front around
Chattanooga. McCook was to the south of Lookout Mountain, Thomas occupied
Cooper's and Stevens' Gaps in the middle of Lookout Mountain (with the
help of a local Union sympathizer), and Crittenden was to occupy Chattanooga. He moved into it without opposition on 9 Sept. 63
after Bragg
had left upon learning that the Union troops
were in control of Lookout mountain. However, all reports that Bragg was
fleeing in disorder toward Atlanta or Rome, Ga. were false and/or planted. Thomas warned
Rosecrans that Bragg was not far away and dangerous to Rosecrans' widely
dispersed forces, and that it was much safer to first concentrate and consolidate
the Union hold on Lookout Valley and Chattanooga before going further.
However, Rosecrans was under ceaseless pressure from Stanton and Halleck to pursue and "destroy" Bragg, and Rosecrans decided to go after him. He was also upset because he had received practically no recognition for his brilliantly concieved and executed Tullahoma campaign and Tennesse River crossing, and he wanted advancement as much as many another general.
Guided by his assumption that Bragg was in full retreat, Rosecrans had ordered
McCook at the southern end of Lookout Mountain to descend into Broomtown Valley
and move toward Summerville in order to attack Bragg's army in the flank.
When McCook got as far as Alpine and discovered that Bragg was not at all retreating,
but rather was concentrated just to his north, he stopped, sent his trains
back up the mountain, requested instructions, and waited. On the 13th he received
orders from Thomas to bring his command to McLemore's Cove and unite with the 14th Corps "as rapidly as possible."
However, even after having spent a week in the Alpine area, he was still poorly informed
of the roads. Instead of taking the most direct road via Dougherty Gap
into the cove,
or the parallel road along the ridge to Steven's Gap, he passed by both roads on his
right, descended into Lookout Valley, and recrossed Lookout Mountain further
north at Steven's Gap. This almost doubled his marching distance and, more importantly, added
a second mountain crossing.
True, it was the safest route, but it cost him 5 days to cover what he could
have done in 1 or 2 days. McCook's report throws little light on his reasons
for his choice of route, but if Rosecrans had heeded Thomas' warnings, McCook
wouldn't have been sent to Alpine in the first place. The map below shows
the route he took and the two shorter ones he could have taken:

McCook's travail
The red dots show the route McCook actually took, and the blue line passing through Dougherty Gap shows the shortest route he could have taken into McClemore's Cove. There was also the parallel road along the ridge to Steven's Gap (the blue dots), but it wasn't indicated on some of the period maps, and it appears that neither McCook nor Thomas knew about it. Driving Tour of McLemore's Cove To better understand the events in and around McLemore's Cove (which set up the battle of Chickamauga), I suggest the following 2 hour driving tour. Start at Point Park on Lookout Mountain and take highway 157 south along the ridge for 15 miles. Turn left on Dougherty Gap Road and descend through hairpin turns into McClemore's Cove. Notice how narrow the valley is at that point. Go left at the first fork and pass through Cedar Grove. While driving look up to see the ridge above you on the left. When you reach highway 193 you are where Bailey's Crosscroads was. Turn right and drive 2 miles east to Davis Crossroads which was Thomas' and Negley's forward position on 10-11 Sept. Then drive 2 more miles east to Dug Gap, a climb with switchbacks, Bragg's forward position. Turn around and return to Davis Crossroads, continue on highway 193 until you reach highway 138. Turn left, and drive up to Steven's Gap. At the top you will have rejoined highway 157 which, if you turn right, will take you back to Point Park. If you have time, drive back down to Davis Crossroads and turn left toward the Chickamauga visitors' center. As you drive, notice how this end of the valley opens out. This tour will give you a good idea of what the commanders of those times had to face. Remember, they had to carry most of their supplies with them in horse-drawn wagons. |
As a result of McCook's wrong turn, the rest of Rosecrans' army, instead
of retiring in an orderly manner into the fortifications of Chattanooga or at least Rossville, had to wait for McCook in a position of extreme vulnerability.
Fortunately for the Federals, Bragg had decided to wait for the arrival of
Longstreet before making any more attacks. The head of McCook's column reached
Thomas on the 17th, but the tail didn't reach Rosecran's right wing
until the morning of the 20th (Col. Jonathan R. Miles of the Twenty-seventh
Illinois Infantry who joined Wilder). In chapter 12 of his 1894 "History of the
Army of the Cumberland," Henry M. Cist sums up this situation as follows:
Bragg had prepared a trap. Hindman was to attack Negley from the wide
open valley opening to the north, and Daniel. H. Hill was to attack from
Dug Gap in the East upon the signal of the sound of Hindman's attack. Negley
might have been caught in a bottle if Hindman, fearing himself an attack
against his right flank, hadn't perceived discretion in his orders and delayed.
Bragg, waiting with Hill at Dug Gap and listening for gunfire from the north
side of the Cove, hesitated also. His "resolution weakened during the day
as he imagined Crittenden and McCook were closing in on his flanks" (Cozzens,
This Terrible Sound, p. 74-75). Moreover, his experience of the last
couple of months must have made him suspect some sort of ruse on Rosecrans'
part, not knowing that, this time, Rosecrans hadn't drawn the card to fill
his straight flush. While Bragg attempted to get Hindman to move, which would have
firmed up his own indecision, his intended prey pulled part-way back
west out of the Cove, Baird came down and reinforced Negley's flank, and
Bragg's moment passed.

McLemore's Cove
Highway 157 on the left follows the top of Lookout Mountain (see Driving Tour above). The original road (blue dots) between Steven's Gap and Bailey's Crossroads no longer goes through, and the connecting road to Cooper's Gap (green splotch) also no longer exists. The squiggle near Estelle at the right is Dug Gap where the Confederates' advanced position was located. The main part of Bragg's army was at La Fayette, about 5 miles to the east. On 9 Sept. Negley got as far as the red star at Davis Crossroads and stopped. His scouts told him there were a lot of enemy soldiers in front of him. They were right. |
Bragg then ordered Polk to attack the isolated corps of Crittenden
near Chattanooga, but Polk fumbled it. On 13 Sept., when his skimishers encountered
those of Crittenden, Polk overestimated the size of the force facing him,
perhaps thanks to Wilder's firepower, and had his men fortify. He called
for reinforcements, but only Bragg came to find out what had happened. The
shouted invective of the two generals was easily heard by the troops outside
the tent. By the way, until the 20th Wilder had practically an independent
command and was called to reinforce threatened points all along Rosecrans'
six-mile long line.
During the next week Bragg undertook nothing while he waited for Longstreet who's arrival would give him numerical superiority. This was perhaps the only major battle of the war in which the Confederate forces (about 70,000) outnumbered the Federal forces (about 58,000). To the Confederate total should be added several thousand men of the Georgia militia which had taken over guard duties in the rear "in order to give Bragg every available fighting man" (Coppée, General Thomas, 1893, pg. 131). Rosecrans had received a report that troops from the Army of Northern Virginia had been spotted traveling south, so he must have at least suspected where they were headed. In the weeks preceding the battle he made repeated requests to the War Department, which was hounding him to destroy Bragg, to send him more men. Burnside at Knoxville was repeatedly ordered to go to Rosecrans, but he also felt shorthanded, had ambiguous instructions from Halleck (connect with Rosecrans but do not, repeat, do not relinquish East Tennessee), and was under pressure from Governer Johnson in Nashville to not abandon East Tennessee. At first Burnside stayed put. Finally he did move but, when the battle began at Chickamauga, he had got no further than Kingston, 25 miles outside of Knoxville. He turned back when he learned the outcome of the battle. Grant at Vicksburg was not shorthanded and his troops were not seriously engaged or threatened anywhere. On 13 Sept. he also had been ordered to send Rosecrans reinforcements, but he was absent from his command (partying in New Orleans), his second in command Sherman undertook nothing, and the reinforcements weren't sent until 27 Sept., after the battle had been fought. Read or reread my summary of the battles of Iuka and Corinth to find out what may have motivated Grant to act like that.
According to Ambrose Bierce, topographical engineer under Hazen during the battle of Chickamauga, the battle was about "control of a road," namely La Fayette Road. There were actually three roads leading from the Union lines back toward Rossville, namely Dry Valley Rd. (the escape route of Rosecrans' right wing on the 20th, McFarland Road (Thomas' route of retreat the evening of the 20th), and La Fayette or State Rd. (the main road to Rossville Gap which Bragg wanted to cut).
The first large scale contact actually took place on the 18th between the respective cavalries as Bragg prepared to put his army across the Chickamauga. The terrain was utterly unsuited for a coordinated attack or defense as most of the area was virgin forest. Steele writes: "Neither army knew the exact positions of the other...It is probable that division commanders on either side hardly knew where their own commands were, in the thick woods, let alone the other troops of their own army, or the troops of the hostile army. The lines were at this time about six miles long." Add to this the arrival of Longstreet's corps on the same day and the arrival of Longstreet himself the next night, and it is easy to imagine the confusion in the dispositions on both sides.
All of Thomas' intelligence indicated that Bragg intended to aim his
heaviest blow at the Union left. During the night of the 18th Thomas therefore
moved his corps north from the Union center, around and behind Crittenden, and to the Union left, thus placing his
corps on the roads leading back to Rossville Gap and Chattanooga.
At dawn Baird had reached Kelly Field. It was this shift which thwarted
Bragg's plan of attack and made the saving of the Union army possible. At this point Bragg would have been very surprised to hear anyone describe Thomas as being slow. Thomas
made this risky move, albeit screened by forest and Chickamauga Creek, in the face of Confederate
units under Polk less than a mile away. Neither force was aware of the presence
of the other, but the Confederates camped while Thomas rode back and forth
along his columns moving north. "Why, it's old Pap hisself," a surprised
soldier would exclaim when Thomas in person appeared to clear a traffic jam.
In the morning Thomas' unrested troops prepared breastworks*, and Croxton attacked Forrest. This brought on the general engagement which turned into an all day melee in which
neither side could claim any advantage.
Neither Rosecrans nor Bragg could exercise meaningful command, and brigades
fought brigades independently, as both armies sidled north. That evening
after dark Cleburne attacked the Union left, but was beaten off.
For the next day Bragg made his usual complicated battle plan which dictated
a dawn attack in Polk against the Union left which would then ripple down the line, but there was no early attack.
Polk either did not pass the order on to Hill, or he did pass on the order,
but Hill received it too late to get an early start. The truth is buried
in the murk of accusation and counter-accusation, but in any case Polk adhered
to his pattern of not taking Bragg's battlefield directives seriously. Longstreet, having arrived
the previous evening and been given command of Bragg's left, was to attack
upon hearing the battle begin on the other end of the line, but when there
was no attack at either end, Bragg sent orders to move forward directly to the division
commanders. Thomas on the left began to feel heavy pressure from Confederates
trying to get around his left and called for reinforcements. This led Rosecrans to shift
some units in his direction, which resulted in a hole being created inadvertently
on the Union right when Rosecrans sent the following order to Wood:
<ar50_103>
HEADQUARTERS, September 20--10.45 a.m.
Brigadier-General WOOD, Commanding Division:
The general commanding directs that you close up on Reynolds as fast as possible and support him.
Respectfully, FRANK S. BOND, Major, and Aide-de-Camp.
Rosecrans' order presupposed a gap between Wood and Reynolds, but there was none, but rather the division of Brannan was there. There was a small space between Brannan and Reynolds which a courrier had noticed and reported to Rosecrans. Brannan had been ordered to Thomas, but he hesitated to leave while in the face of imminent attack. To obey the letter of at least part of the order and close up on Reynolds, Wood therefore had to pull out of line and move behind Brannan.
The oft repeated tale that Wood willfully, on his own, and out of spite
carried out an order he knew to be ill-advised is probably exagerated. Most commentators fault Wood because he certainly knew that to
move just then was risky,
as Longstreet's skirmishers were already advancing. However, he had already
been twice upbraided by Rosecrans for not rigidly following orders, most
recently earlier that same morning for failing to promptly carry out, you
guessed it, an ambiguous order. He had been ordered to fill Negley's place
in line who had been ordered to join Thomas. But Negley didn't move, and
Wood could not relieve him. Rosecrans, overwrought and unable to control
his emotions, blamed Wood for Negley's tardiness and said so in public using insulting and threatening language.
Now Wood was handed a poorly written order, and McCook, exhausted and confused,
his superior in rank although not his direct commander, told him to try
and carry it out, and that he would fill the gap with other troops. McCook
made this offer after having received information from his skirmishers that
a large Confederate force was heading in his direction. However, at that
point there wasn't much McCook could have done. He was stretched to the breaking
point by the troops taken from him and sent to Thomas, and Sheridan and Davis
were in motion when Longstreet's column of 20,000 men struck the gap left
by Wood. Glen Tucker summed up the other point of view when he wrote: "There
can be little doubt that Wood acted in good faith" ("Chickamauga," pg. 258).
Regardless of McCook's ability or lack of it in a crisis, Rosecrans was at
fault for again having put McCook in that spot. Rosecrans had not followed
Thomas' advice, proferred at the council of war in Widow Glen's house the
previous evening, to move the entire right wing up to the Dry Valley Road.
Perhaps Rosecrans was reluctant to impose yet another night march, even of
a couple of miles, on an overworked army. This is what can happen when an
abstract plan is rigidly carried through in spite of unforseen exigencies.
Rosecrans had let himself be seduced by the beauty
of his plan.
McCook, Negley and Crittenden were later brought before a court of inquiry, but not convicted for leaving
the field of battle. They were found to have committed no more than an "error of judgment" (ar50_1053), but
their active roles in the war ceased nevertheless. Judging from McCook's
performances at Perryville and Murfreesboro it should have ended earlier,
but the McCook family was influential. He was genial and personally courageous,
but incompetent as a corps commander. Wood was not tried, perhaps because
he was felt to be not at fault, or because later that day he played an essential
role in stabilizing Thomas' position on Snodgrass Hill. In a message dated
15 Oct. 63 Rosecrans praised Wood's performance and even recommended him for
promotion (ar53_387). However, he was censured by
the Negley court of inquiry for "severe reflections upon the conduct of Major
General Negley, applying to him coarse and offensive epithets" (ar50_1044).
Sheridan also plied Negley with offensive language, but was not censured.
The whole question of responsibility for opening the gap is moot because Rosecrans,
by initially misreading Bragg's intentions, by disregarding on repeated
occasions sound advice from Thomas, and by shrugging off intelligence that
Bragg was being reinforced, had already created a chaotic command situation
in which any error would have dire consequences, and there are always errors.
Under such circumstances, Longstreet's attack may have overwhelmed the Union
right anyway.
In any case a hole was made, and the massed column under Hood happened
to find it while making one of his all-or-nothing attacks, and the
Federal right, already in a state of confusion, collapsed. Rosecrans, McCook,
Crittenden, Davis, Negley (taking with him most of the Union artillery), and
Sheridan left the field. When Rosecrans arrived at Rossville he met his chief
of staff, Garfield, and debated what to do. According to Henry Cist, another
of Rosecrans' staff who may actually have been a witness, Garfield advised
Rosecrans to go back to Chattanooga while he, Garfield, would report to Thomas
(Cist, "History of the Army of the Cumberland," chapt. 12). This was bad advice
from a man who before the crossing of the Tennessee had been sending back
secret reports to Chase unfavorable to Rosecrans, so Garfield left the field
that evening, when Thomas withdrew, with something on his conscience.
After the collapse, the only unit remaining on the Union right was Wilder's brigade of mounted infantry armed with Spencer repeaters
which made so much noise that Longstreet hesitated to order his men forward,
thinking that Wilder represented a large force on his flank. This
at least bought some time for Thomas to get set on Snodgrass Hill. Wilder
sent an aid to ask Sheridan, who was retreating, for help, and Sheridan told
him, "to get out of there" (Samuel C. Williams, "General John T. Wilder," 1936, pg. 33, quoted also in Tucker, pg. 316). The day before at the other end of the line, and that morning on the Union far right, Wilder had stopped Confederate
attacks cold. Now, after the collapse of the Union right, he was about to attack Longstreet in the
flank and cut his way through to Thomas, because anyone with ears and a
clear mind knew that Thomas hadn't quit. Then
a panicked Charles Dana, Assistant Secretary of War and Stanton's very capable
but not battle-tested informant, was riding in the wrong direction
toward Confederate lines and, luckily for him, ran into Wilder. He told Wilder that the entire army was routed
and Rosecrans killed or captured. He positively ordered Col. Wilder to escort
him back to Chattanooga, and to fall back to Lookout Mountain in order to
"hold it at all hazards" (Tucker, pg. 317). Being only a colonel and
not knowing that Dana did not have the authority to give such orders, Wilder
stopped his preparations, sent Dana back to Chattanooga with some scouts,
and began to restore order in his sector. His brigade remained on the field
until the next morning and, along with Dan McCook's brigade on the other wing, was the last to retire.
All of the commanders on the division level and above who left the
field on the 20th were sidelined for the rest of the war, except Davis and
Sheridan. Davis saved himself later that afternoon by the gesture of promptly or fairly promptly reversing direction when so ordered,
but Sheridan decided that his battle was over and marched away, allegedly
with the intention of returning via Rossville to support Thomas's northern
flank. Col.
Thruston, chief of staff of McCook's XX Corps (to which Davis and Sheridan
belonged) had reported to Thomas that Sheridan, along with Negley and Davis
with about 7000 men were still close by. Thomas sent Thruston to direct the
three division commanders to come back to "aid his right," something which they should have done anyway, without orders. Forcing his way through
along a road clogged with retreating men and equipment, Thruston found them still at
McFarland's Gap and conveyed Thomas' order. Davis allowed his soldiers get
water, and then headed back toward Thomas' right, taking some of Negley's
troops with him, albeit without getting very far. But Sheridan and Negley kept on toward Rossville. As Thruston
wrote in his article The Crisis at Chickamauga in "Battles and Leaders" (Vol III, pg. 665):
"Sheridan was still without faith. He may have thought there was danger
at Rossville, or that his troops had not regained their fighting spirit.
He insisted on going to Rossville. Darkness would catch him before he reached
the field from that direction. Negley was vacilating; he finally went to
Rossville."
Piatt ("Life of Thomas," pg. 430-31) writes the following about this encounter:
"General Thruston, in making his statement, omitted from the writing precisely what General Sheridan did say, and this language the gallant young chief of staff omitted from a mistaken sense of propriety. The fact is, the insubordinate subordinate, in a sentence glaring with profanity, swore he would obey no such orders and take his men into a slaughter organized by fools....A braver man never trod the field of danger. His mind was clear and his nerves calm, and he knew that in that roar that rose behind him as he marched away brave men were being done to death, while heroic officers were looking eagerly to the right and left for aid in this hour of death-tainted anxiety."
Sheridan played no further role in the battle, but for some reason he
got a pass while Negley lost his command, as did Rosecrans, McCook, Crittenden,
and Van Cleve, regardless of the pressing reasons they put forth in defense
of their decisions. It is possible that the War Department had been waiting
for an opportunity to get rid of these commanders anyway. Rosecrans' abrasiveness
and perhaps his ambition had long grated on Halleck, and the government wanted to deflect criticism
that it hadn't properly supported Rosecrans, so he would do as a scapegoat.
McCook had struck out a third
time in a major battle, and nobody wanted to serve under him any more. Crittenden
had apparently lost heart, perhaps because the war was taking a direction
he hadn't predicted, perhaps the family plantation back in Kentucky was
not doing well as restive slaves slipped away. Dana could not have been far
off the mark when wrote the following about the two:
<ar50_202>
"The feeling in the case of McCook is deepened by the recollection of his
faults at Perryville and Murfreesborough, and of the great waste of life
which they caused; while toward Crittenden it is relieved somewhat by consideration
for his excellent heart, general good sense, and charming social qualities.
Against these, however, is balanced the fact, which I can testify to from
my own observation, that he is constantly wanting in attention to the duties
of his command, never rides his lines, or exercises any special care for
the well-being and safety of his troops, and, in fact, discharges no other
function than that of a medium for the transmission of orders."
Consider this exchange reported by Parkhurst who had been collecting stragglers and fugitives fleeing from the field:
<ar50_264>
"The troops from the front continued to rush on toward my line in great confusion,
and at this moment I discovered Major-General Crittenden, of the Twenty-first
Army Corps, with some of his staff. I immediately rode up to him and respectfully
asked him to stop and take command of the forces I was collecting and had
then collected, and place them in a position to resist an attack or take
them back to the battle-field, which I then supposed and now believe could
have been successfully accomplished. Major-General Crittenden declined
to take command, saying, "This," meaning the forces there collected, 'is
no command for me.' I remarked to the general that the force I then had collected
and should succeed in collecting was too much of a command for me. General
Crittenden replied, 'You have done marvelously well and you had better keep
command.'"
No high ranking officer who displayed such an attitude in such a situation could remain in his position.
Negley also had some explaining to do. Well before Longstreet's attack
Thomas had ordered him to place his artillery (about 50 guns) on the far
Union left in order to cover the main road. However, when Longstreet's attack
developed he was still a mile from his objective and got involved with the
rout of McCook's corps, taking with him those 50 guns which had not fired
a shot. Thomas put it kindly in his report when he wrote that Negley "must have misunderstood my order" (ar50_251). He had performed well at Murfreesboro, but he had a terrible
day at Chickamauga. True, he was suffering from dysentery, which was no laughing
matter as it could be fatal in those days before the role of bacteria in causing
disease had been discovered. Perhaps the fact that he hadn't attended West
Point, was, as he later maintained, a factor in the decision to sideline
him. More importantly, when he had the chance to redeem himself, he kept
on going to Rossville. True, he made himself quite useful there by gathering and organizing stragglers, but he didn't have Sheridan's robust p.r. instincts and
effrontery to fake a return to the field. Van
Cleve, 53 years old and already graying, lost his composure on the 2nd day
of Chickamauga, was entirely separated from his command, and let himself
be swept along to Chattanooga. In memorium to an unsung hero of the battle
of Murfreesboro, I quote here from Hazen's memoirs ("A Narrative of Military Service," 1885, pg. 127-28):
"As I hastened forward to learn the condition of affairs, I met
General Van Cleve, a division commander of Crittenden's corps, riding wildly
up the road, with tears running down his cheeks, who asked if I had any troops
as they were wanted badly 'just down there,' - pointing in the direction
I was going, - saying he had not a man he could control....His distress was
not feigned."
Sheridan had not had much of a day either. Even if we accept his report
as being partly true, he still disregarded Thomas' order to return to Snodgrass
Hill, and he contributed nothing to solve the dilemma in which the Union army
found itself that afternoon, without consequences for his subsequent career.
Did Sherman's friendship and Halleck's protection have anything to do with
it? The matter would be of little interest if this man hadn't risen later
to the position of Commander-in-Chief of the Army (1884-1888) and four star
general (1888). My essay Sherman's Ride at Chickamauga
contains a more detailed analysis of Sherman's movements the afternoon and
evening of 20 September.
By noon or thereabouts, Thomas was alone with about 25,000 men on the
field against about 60,000 Confederates. As his situation became clear to
him, Thomas concentrated troops around Snodgrass Hill, left those in Kelly Field where they were,
and resolved to stay and fight until nightfall, which he did. He was helped
by the relative passivity of Polk, whose troops were apparently fought out. The
keys, however, to Thomas' survival that afternoon were the lack of coordination
of the mainly frontal attacks which an overconfident Longstreet (who sat
down at 2 PM for lunch) carried out from the southern end of the Confederate
line, and the arrival
on Thomas' left of Granger and Steedman in the
afternoon with the reserve corps. They brought with them about 4000 men
(a bit more than 2 brigades), some artillery, and much needed ammunition.
Thomas is supposed to have said, "General Steedman, I have always been glad
to see you, but never so glad as now." Steedman brought his men behind the
Union position and personally led the charge which drove off a contingent
of Longstreet's troops who were threatening to envelope Thomas' right. At
one point Steedman even carried the colors in order to rally a unit of wavering
soldiers. Steedman's 2 brigades alone suffered about 1000 casualties that
afternoon.
Thomas constantly rode back and forth along his perimeter
stretching from Snodgrass Hill to the end of Horseshoe Ridge, placing his
units, encouraging his men: "Steady, there, steady. Shoot low and pick your
man."
Plugging gaps as they opened and readjusting the lines as new threats appeared,
"he issued orders to restore the line in the quiet conversational tone that
politeness prescribes for a ladies' drawing room. It was the discipline
of a lifetime concentrated in a moment" (Wilbur Thomas, pg. 392). At least
once he got as far as La Fayette Road, because, according to Reynold's report,
Thomas personally directed Turchin's final attack which stabilized the left
flank for the withdrawal to McFarland's Gap. I quote the entire passage here
because it perfectly illustrates Thomas' command presence and style when
he was in the thick of battle:
<ar50_442>
"Arriving at the Rossville road, the command was met by the corps commander
in person, and I was directed to form line perpendicular to the Rossville
road. This done General Thomas pointed in the direction of Rossville and
said, "There they are; clear them out." The division was faced about and
a charge ordered and executed in two lines at double-quick, through the rebel
lines, dispersing them and capturing more than 200 prisoners under a fire
of infantry in front and artillery in flank.
I understood that this movement was intended to open the way to Rossville
for the army, and did not then know of any other road to that point. I therefore
pressed right on in the charge, expecting the whole division to do the same
until the rebel lines and batteries were cleared and the road opened, and
found myself with only about 150 of the Third Brigade, under Colonel Lane,
Eleventh Ohio, near the field hospital [Cloud's] of the Fourteenth Corps.
The remainder of the division proceeded to the high ground on the left by
order of General Thomas. The Third Brigade was reformed by Brigadier-General
Turchin, who had his horse shot under him in the charge. The Second Brigade
was reformed by Col. M. S. Robinson, who succeeded to the command of that
brigade after the death of Col. E. A. King. The advanced party rejoined the
division on the ridge to the west of the road, and the whole division marched
to Rossville by the Valley road."
Although some commentators like to speculate that Rosecrans and Thomas could have counter-attacked a weakened Bragg on the 21st, most write of Thomas' precarious situation at the end of that day. However, it is apparently not widely understood just how precarious it was. Of modern authors only Tucker ("Chickamauga," pg. 353) deals with this problem. There was namely, as the following map shows, a gap between Kelly Field on the right, and Snodgrass Hill on the left.:
|
| Snodgrass Hill and, to the left, Horseshoe Ridge.
Thomas' HQ was at the star. Separated by a stretch of woods was the fortified
position of Kelly Field. Willich had a brigade with which to make a
lot of noise if the Confederates moved in force in his direction. |
The space was wooded, and Thomas had posted there only a brigade under Willich
(circled in red) in the hopes that the trees would mask the weakness. Moreover, Willich** was once drawn away to aid Baird (ar50_535), during which time the gap was empty.
Thomas was bluffing the entire afternoon of the 20th, or,
to put it more kindly, was forced to speculate on Confederate errors.
We get an idea
of one of these errors from Humphreys, the Confederate brigade commander
adjacent to Willich, who stated the following in his report:
<ar51_509>
"I immediately informed General Longstreet of the enemy's position and strength,
and received orders from him to hold my position without advancing, while
he sent a division to attack him on the right and left. The attack on my
left was first made with doubtful success; the attack on my right was successful,
driving the enemy from his position in great confusion. It was now dark and
no farther pursuit was made."
In fact, Longstreet carried out one frontal attack after another against
Snodgrass Hill until very late in the day. Longstreet himself counted 25
of them. Humphreys does not state what he related to Longstreet, nor does
Longstreet mention Humphreys' intelligence in his own report, but Humphreys
had five hours to reconnoitre his left flank. If he did discover Willich's
weakness and reported it, then Longstreet did not react quickly enough. Of
Polk's division commanders Stewart was the closest to the gap, but he was
receiving conflicting orders from Bragg, Longstreet, and Buckner (ar51_364).
His report doesn't mention any attempt to reconnoiter his left flank. In
any case, if one of the many Confederate divisions in that area had brushed
Willich aside at any time that afternoon, or if Preston had been informed
of the gap when he was brought in, Thomas would have been quickly driven
from the field in disorder, and that would have been that. Those 7000 men
under Davis, Negley and Sheridan would have done nicely to help Thomas fill
that gap and reinforce a flank, and from about 2 to 4 PM that afternoon,
they were only a couple of miles away. With that gap filled, Thomas would have had a
least a choice to withdraw or not to withdraw. Sheridan, occasionally
a man of energy, could have got them to Thomas. You be the judge.
When the day ended the attacks gradually ceased. Thomas was able to withdraw through McFarland
Gap to Rossville in stages and in a fairly orderly manner, and he thus saved the Union
army. However, the withdrawal from Kelly field was contested, as the following extract from Baird's report shows:
<ar50_279>
"As my men fell back the enemy pressed after them, and in crossing the open
field very many were struck down. They reached the woods, west of the road,
in as good order as could be expected, but then, uncertain which direction
to take, and having no landmark to guide them, many became separated from
their regiments, and in groups joined other commands, with which they fell
back to Rossville, where all were united during the night. A number, doubtless,
became confused at this time and marched into the lines of the rebels. We
had, during the day, been fired into from every point of the compass, and
when we fell back, no other portions of our troops being in sight, it was
impossible to tell where they could be found or when we would encounter the
enemy. My loss, up to the time of falling back, was small compared with the
punishment in-dieted on the rebels. In retiring, it was great."
This is confirmed by Palmer's report:
<ar50_715>
"At about 5 o'clock I received an order from Major-General Thomas, by a staff
officer, to retire. Under the impression that it was intended that I should,
after retiring toward the rear of the center, form to resist the attacks
which were coming on both flanks, I sent my orders to my brigade commanders,
and rode to the Rossville road to await the head of the column. I reached
the road and looked back across the field some 400 yards; my men were half
way across. The enemy had already discovered the movement, and were crossing
the barricades and firing. Batteries opened on us from the left and right,
sweeping the road and field from opposite directions. It seemed impossible
to bring men across the field in anything like good order. Grose was thrown
into confusion, but Cruft came off in good style, and both with little loss.
Cruft's brigade was retired slowly after leaving the field, frequently halting
to serve as a nucleus for the reformation of our scattered troops. These
brigades were conducted to the top of the ridge, formed and held until large
crowds of stragglers passed, and, as I received no orders from any quarter,
at late dusk I gave orders to the brigades to descend into the valley, throw
out strong guards in the rear and front to resist any possible attack, and
march to Rossville. The head of the column reached there at 8.40 p.m."
Longstreet was content with the day's work, as this sentence from his report shows:
<ar51_289>
"A simultaneous and
continuous shout from the two wings announced our success complete. The enemy
had fought every man that he had, and every one had been in turn beaten."
This is echoed in this passage from Ambrose Bierce:
"At last it grew too dark to fight. Then away to our left and rear
some of Bragg's people set up the 'Rebel yell.' It was taken up successively
and passed around to our front, along our right and in behind us again, until
it seemed almost to have got to the point where it started. It was the ugliest
sound that any mortal ever heard - even a mortal exhausted and unnerved by
two days of hard fighting, without sleep, without rest, without food and
without hope. There was, however, a space somewhere at the back of
us across which that horrible yell did not prolong itself; and through that
we finally retired in profound silence and dejection, unmolested."
However, it can be said that, in the military sense, Thomas advanced to Rossville and Chattanooga. For this exploits he
became known as the Rock of Chickamauga, perhaps in reference to Dana's
report of the afternoon of the 20th which stated that, "Our troops were as immovable as
the rocks they stood on" (ar50_194). It
is often asserted that a message of that afternoon from Garfield to Rosecrans
contained the phrase: "Thomas standing like a rock." However, such a message
is not contained in the Official Records. There is, however, a message of
15 Oct. 63 from Rosecrans to Adjutant General Lorenzo Thomas in which he
stated that Brannan with his division "stood like a rock" (ar53_387). Another of the Civil War's mysteries.
More than a year later, in recognition of his stunning victory at the battle of Nashville, Thomas was promoted to major general of the regular army. Upon learning of this Thomas, in a departure from his usual reticence, said, "I suppose it is better late than never, but it is too late to be appreciated; I earned this at Chickamauga." His reaction would perhaps have been stronger had he known then that Grant had caused the promotation to be delayed for a few weeks so that Meade's, Sherman's and Sheridan's promotion to the same rank would predate Thomas'.
The casualty statistics are eloquent. Out of 58,000 Union effectives there were around 16,000 casualties (27%), and out about 70,000 Confederate effectives there were more than 18,000 casualties (around 26 %). This battle has been called the bloodiest two days of the war. Bragg had won a victory of sorts, but his army was as bad off as Rosecrans'. Bragg was not willing, and his army was probably not able to pursue, so Rosecrans held onto Chattanooga. Bragg's victory was barren, while Rosecrans's loss was, in the long run, inconsequential.
Even today many commentators fault Bragg for not having vigorously pursued on the following day. They overlook the fact that every victorious Civil War army on either side, after having sustained such high losses, required days or even weeks to recover some degree of organization, repair damaged equipment and transport, and to replace horses, of which hundreds or even thousands died in every major battle. The victors generally recognized the advantages of a successful pursuit, but their armies were not capable of it. The commentators also leave the Thomas factor out of their calculations. On 20 Sept. 1863 Thomas had not been defeated, and on the following day his corps was still a powerful force to be reckoned with. Bragg and other Western Theater commanders on both sides knew what that meant after having either faced Thomas or fought beside him, or otherwise observed Thomas' career up to that point.
At Chickamauga Thomas' contribution was unique and decisive. The reluctance of many to accord him his rightful place in history has various reasons. Some of his fellow Union officers could not advance their careers unless they checked his and tarnished his reputation. Even today some Southern commentators regard him as a traitor to their cause, discounting the possibility that he acted also in the South's long-term interest (see my Essay Bring Thomas Home). Northern commentators, even today, perhaps would rather not admit that the Union victory was largely the work of a Virginian.
So what's your excuse?
* From "Chickamauga - The Great Battle of the West" in "Battles and Leaders", essay by D.H. Hill, editors' note: "General Thomas had wisely taken the precaution to make rude works
about breast-high along his whole front, using rails and logs for the purpose.
The logs and rails ran at right angles to each other, the logs keeping parallel
to the proposed line of battle and lying, upon the rails until the proper
height was reached. The spaces between these logs were filled with rails,
which served to add to their security and strength. The spade had not been
used."
** Willich, a refugee from the 1848 revolution in Germany, performed amazingly well that afternoon, according to Johnson's report:
<ar50_536>
"By having Willich in reserve he was enabled to engage the enemy in four
different directions, and by his prompt movements he saved the troops from
annihilation and capture....Brig. Gen. A. Willich, commanding First Brigade,
was always in the right place, and by his individual daring rendered the
country great service. This gallant old veteran deserves promotion, and I
hope he may receive it."
Willich did not receive his promotion until after the war, and then
only to brevet Maj. Gen. USV, a meaningless rank in peacetime. A possible
reason for this may have been his politics, as he was an avowed socialist.
Consider, for example, what "der rote Willich" wrote toward the end of his Chickamauga report:
<ar50_541>
"I do not feel competent to bestow praise on the officers and men of my command;
for their bravery and self-denial they are above praise. They have again
and again proven that they are true sons of the Republic, who value life
only so long as it is the life of freemen, and who are determined to make
the neck of every power, slaveratic [sic] or monarchical, bend before the
commonwealth of the freemen of the United States of America."
To some of his fellow and superior officers, such sentiments must have
seemed as frightening as those of the Confederate opponents.

CHAPTER VI
THE ARMY CROSSES THE TENNESSEE RIVER - GENERAL BRAGG EVACUATES
CHATTANOOGA - PURSUIT IS OPPOSED BY THOMAS, BUT NEVERTHELESS
ORDERED - THE THREE CORPS WIDELY SEPARATED - THOMAS' TROOPS
MEET THE ENEMY AT DUG GAP - BRAGG'S ARMY CONCENTRATED BUT
FAILS TO STRIKE EITHER OF THE ISOLATED CORPS - ARMY OF THE
CUMBERLAND CONCENTRATED ON THE l8TH - FIRST DAY OF BATTLE
AT CHICKAMAUGA.
Late in August, in compliance with peremptory orders from Washington,
the army again moved forward, crossed the Cumberland Mountains, the Tennessee
River, and the mountains immediately south of that river, and on the 8th
of September, was encamped in Lookout Valley, near the western base of
Lookout Mountain. Here General Rosecrans had his army in hand, except four
brigades that had advanced directly towards Chattanooga from the north.
The position of the army in Lookout Valley threatened General Bragg's communications
south from Chattanooga. The Twenty-first corps was near the northern base
of Lookout Mountain, on the direct road to Chattanooga, the Fourteenth
corps was before Stevens' Gap, with its advance on the summit of the mountain,
and the Twentieth corps was at Winston's with its foremost troops also
upon the summit. The mountain then separated the two armies. General Bragg
had been withdrawing his army for two days on the road leading to Lafayette,
Georgia, and late on the 8th his rear guard retired from Chattanooga.
Very early the next morning General Rosecrans was informed of the evacuation
of the town.
Page 103 - BRAGG EVACUATES CHATTANOOGA
General Bragg abandoned Chattanooga in expectation of soon regaining it. His supplies were not sufficient for a siege, and his army was not large enough to hold Chattanooga and cover his communications. He consequently moved south a few miles to save his communications and meet expected reenforcements, where his army might face the mountain passes and strike unsupported corps, as they should debouch from different mountain gaps into the eastern valley. At this time the Confederate authorities were making efforts to give Bragg such an army as, in their judgment, would enable him to vanquish the Army of the Cumberland, to carry the war again to the north, and in the farthest reach of hope to end the war with the independence of the Southern States. But to give strategic force to a retreat that was imperative. General Bragg used various stratagems to conceal his purposes. He sent men into the National army to induce the belief that his army was retreating far to the south, and moved his forces as far as practicable to manifest such a purpose.
The strategy which had compelled the evacuation of Chattanooga was consummate. The forces sent by General Rosecrans first to Pikeville and afterwards directly towards Chattanooga, had effectually covered the movement of the army towards General Bragg's communications with Georgia, and had, at the same time, so threatened his communications with Knoxville, and the forces holding East Tennessee, that Buckner's little army had been withdrawn, and the easy possession of that region by General Burnside had been thereby assured. The only effect of this strategy which had not been favorable to the ultimate success of Rosecrans, had been the reenforcement of Bragg's army before Rosecrans by Buckner's command.
To gain Chattanooga the strategy was perfect, but for immediate offensive
operations south from that important point it was radically defective.
When Rosecrans' army was in Lookout Valley, and his detached forces - four
brigades - on the north bank of the Tennessee, with open ways into Chattanooga
from
Page 104 - LIFE OF GENERAL GEORGE H. THOMAS
the north and the south, he had gained the objective of his campaign, and the concentration of his army in that town could have been effected without resistance by the enemy. But the pursuit of the enemy, not the occupation of Chattanooga in force, became his object as soon as he was informed that the town had been abandoned.
On the morning of the 9th, General Rosecrans sent the following message to General Thomas:
HEADQ'RS DEP'T OF THE CUMBERLAND, Trenton, September 9th, 3.30 A. M.
At the time of the abandonment of Chattanooga by the enemy, two corps
of the Army of the Cumberland were within a day's march of that place ;
one of these being very near, since Wood's division of the Twenty-first
corps occupied Chattanooga at noon of the 9th. The Twentieth
corps was about
Page 105 - URGES CONCENTRATION OF THE ARMY
forty miles distant, and could have marched to Chattanooga by noon on the 10th. By that time the main army could have been concentrated in the town with strong detachments on the road to Bridgeport. The mountain would have covered the movement of the Fourteenth and Twentieth corps down Lookout Valley, and Crittenden's corps could have held the town and covered the approaches from the south and east, aided by the brigades from the north bank of the Tennessee. The concentration could have been effected, if it had been the purpose of General Bragg to oppose; but that it was not his intention is expressly stated in his official report, and was evinced at the time by his retreat far towards Lafayette, Georgia. Bragg was not ready for battle in proximity to Chattanooga, and his army was not in a position to prevent the concentration of the Army of the Cumberland in the town, had that been General Rosecrans' object. But the situation gave room for an easy, unrestricted occupation by the whole army. All the roads on the west side of Lookout Mountain were held by the National army, and all converged upon the one which passes over the 'nose' of Lookout, where that mountain abuts the Tennessee River, three miles from Chattanooga, and there was no enemy near to prevent, or even contest, the use of that road. There was not, therefore, a single obstacle to the concentration, and this fact taken in connection with the actual movement of a division into the place from the south, the crossing of troops into it from the north bank of the river, and the march of two divisions in front of it from Lookout Mountain to Rossville on the 10th, proves beyond question that General Rosecrans had gained his objective before he ordered the pursuit of the enemy. He must have thought so himself, or he would not have established his headquarters at Chattanooga behind his army.
In view of the manifest practicability of the concentration of the army
at Chattanooga, Thomas urged Rosecrans to abandon his scheme of pursuit
and establish his army at that
Page 106 - LIFE OF GENERAL GEORGE H. THOMAS.
point and perfect communications with Bridgeport and Nashville. After this had been done, the offensive could have been taken from Chattanooga as a base. General Thomas did not know how far Bragg intended to retreat, but independently of the enemy's plans he was urgent that what had been gained should be made secure. He was opposed to a movement that might bring on a battle when the army having nearly exhausted its supplies, transported from Bridgeport, could not follow up a victory, in the event of winning one; and where, if defeat should be the issue, the problem of supplies would be difficult of solution.
But believing that Bragg was retreating on Rome, Rosecrans rejected Thomas' advice, and in doing so entered upon a series of mistakes which culminated, when, by his orders, movements were made on the second day of the battle of Chickamauga, which gave the enemy the opportunity to break and rout the right of his army.
The views of the commanding generals in regard to the situation before the battle of Chickamauga, and in reference to the supposed possibilities to each, are clearly given in their official reports.
These extracts from General Bragg's report reveal his views, purposes and movements.
"Immediately after crossing the mountains to the Tennessee,
the enemy threw a corps by way of Sequatchie Valley to strike the rear
of General Buckner's command, while Burnside occupied him in front. * *
* As soon as this change was made, the corps threatening his rear was withdrawn;
and the enemy commenced a movement in force against our left and rear.
On the last of August it became known that he had crossed his main force
over the Tennessee River at and near Caperton's Ferry, the most accessible
point from Stevenson. By a direct route he was now as near our main depot
of supplies as we were, and our whole line of communication was exposed,
whilst his was partially secured by mountains and the river. * * * The
nature of the country and
Page 107 - R0SECRANS (ORDERS PURSUIT)
the want of supplies in it, with the presence of Burnside's force on our right, rendered a movement on the enemy's rear with our inferior force impracticable. It was therefore, determined to meet him in front whenever he should emerge from the mountain gorges. To do this and hold Chattanooga was impossible, without such a division of our small force as to endanger both parts. Accordingly our troops were put in position on the 7th and 8th of September, and took position from Lee and Gordon's mill to Lafayette, on the road leading south from Chattanooga and fronting the slope of Lookout Mountain."
General Rosecrans thus referred to the situation and the pursuit in his report :
"The weight of evidence gathered from all sources was, that Bragg was moving on Rome and that his movement commenced on the sixth of September. General Crittenden was therefore directed to hold Chattanooga with one brigade, calling all the forces on the north side of the Tennessee across, and to follow the enemy's retreat vigorously, anticipating that the main body had retired by Ringgold and Dalton."
After his consultation with General Thomas, General Rosecrans issued the following order:
TRENTON, GA., September 9, 1863, 10 A. M.
Page 108 - LIFE OF GENERAL GEORGE H. THOMAS
Nothing but the certainty that the enemy was retreating with scattered forces to some remote point, could have warranted such a separation of the three corps of the Army of the Cumberland, as resulted from obedience to this order. The movements in compliance gave General Bragg the advantage for maneuver and battle. He had his army in hand behind the mountains, with short lines to each of the three corps of the National army in their complete isolation.
General Rosecrans had been bold to cross the Tennessee River without assured support on right, or left. But when he had gained his objective it was more than bold to send one corps to the rear of General Bragg's concentrated army, another towards its centre, and a third to its left, and each of the three in perilous isolation. And it was one of the most wonderful series of operations of the war, which brought these corps from isolation into union in front of the enemy, in time for battle.
Bragg had a large army when he left Chattanooga. The five divisions that fought the battle of Stone River were with him, two divisions had joined him from Mississippi, and Buckner's two divisions from East Tennessee joined immediately south of Chattanooga. He had then an army of nine divisions of infantry immediately after leaving that town.
General Thomas was nearest this large army, and his designated line
of advance was directly towards its centre. He was therefore the first
in peril. Besides no general would forget that the overthrow of the central
corps of an army would doubly expose the other two. It was well, therefore,
that the conduct of the perilous advance of this corps was committed to
as prudent a general as Thomas.
* Reynolds' division Fourteenth corps.
Page 109 - CROSSES LOOKOUT MOUNTAIN
On the 9th Negley's division moved over Lookout Mountain and debouched into McLemore's Cove, and threw forward skirmishers to Bailey's cross-roads. In the evening Baird's division crossed the mountain to the eastern base. Reports reached Thomas that the enemy's cavalry was drawn up in line in front of Negley, and that a heavy force consisting of infantry, cavalry and artillery, was concentrated at Dug Gap, beyond Negley's position.
Bragg was apprised of this advance, and promptly prepared to meet it. The following extract from his report gives his general plan of operations as well as his purpose in respect to Thomas' movement: "During the ninth it was ascertained that a column, estimated at from four to eight thousand, had crossed Lookout Mountain into the cove, by way of Stevens' and Cooper's Gap. Thrown off his guard by our rapid movement - apparently in retreat, when, in reality, we had concentrated opposite his centre and deceived by the information from deserters and others sent into his lines, the enemy pressed on his columns to intercept us, and thus exposed himself in detail." That night Bragg formed a combination of three divisions and a cavalry force to move against Negley the next day.
Early on the 10th it was ascertained that Dug Gap had been
obstructed and occupied by the enemy's pickets. If this was a device to
invite the advance of Thomas it failed of its object, since he was the
more cautious in consequence of an equivocal precaution on the part of
the enemy. General Bragg made effort during the day to move his forces
against Negley, but twice, his subordinates failed to carry out his orders.
He did not however abandon the project and at night gave orders for a far
heavier combination for the 11th. Negley's division was exposed
in three directions, through Dug Gap, farther to the left, through Catlett's
Gap, both in Pigeon Mountain, and on the low ground
Page 110 - LIFE OF GENERAL GEORGE H. THOMAS
to the north. That evening Baird's division moved towards Negley's position, and Reynolds and Brannan were ordered to move forward early in the morning. The caution evinced by General Thomas called forth the following despatch from General Rosecrans:
HEADQUARTERS DEPARTMENT OF THE CUMBERLAND, Chattanooga, September 10, 1863 - 9:45 P. M.
Page 111 - BRAGG ORDERS ATTACK
These instructions exhibited an utter misapprehension of the situation. Rosecrans still believed that Bragg was retreating and his plans had reference to pursuit. And Thomas' slow advance under the circumstances did not imperil either McCook or Crittenden, since the longer Bragg was induced to operate against Thomas, the longer would the other two corps be safe. Bragg had choice of corps, as each in isolation was exposed to attack, and it was not in the power of Thomas, McCook or Crittenden to give aid to each other except as each could hold the enemy to the offensive against himself. To be slow therefore under the semblance of offense was the best policy. But at the time that Rosecrans was framing his instructions to Thomas to hasten his movements on Lafayette, Bragg had just moved his headquarters to that place from Lee and Gordon's mill, and was planning to move seven or eight divisions of infantry and a force of cavalry against the foremost divisions of the Fourteenth corps in McLemore's Cove, as the following order and extract from his official report plainly show:
HEADQUARTERS ARMY TENNESSEE, Lafayette, Ga., 12 p. M., September io, 1863.
Page 112 - LIFE OF GENERAL GEORGE H. THOMAS
promptly done, and by daylight he was ready to move. The obstructions in Catlett's Gap were also ordered to be removed to clear the road in Hindman's rear. Breckinridge's division, Hill's corps, was kept in position south of Lafayette to check any movement the enemy might make from that direction. At daylight I proceeded to join Cleburne at Dug Gap and found him waiting the opening of Hindman's guns, to move on the enemy's flanks and rear."
General Hindman had been joined by Buckner's corps the day before, so that Buckner's, Folk's and Walker's corps and one division of Hill's corps, and a cavalry force, under General Bragg in person, were included in the combination against the two advanced division of the Fourteenth corps. And yet these divisions and the other two behind them, escaped overthrow because they had not advanced in compliance with the orders of General Rosecrans.
At 8 A. M., on the 11th, Baird's division was formed on the right of Negley's. By this time it was known that the enemy had removed the obstructions from Catlett's and Dug Gap. Later in the day the enemy advanced through them in heavy force, while another column approached from the north. By skilful maneuvers and gallant fighting Negley's and Baird's divisions, step by step, withdrew from the midst of the three converging columns, and falling back towards Lookout Mountain, were soon within supporting distance of the other divisions of the corps. The strength of the enemy's columns developed the fact that there was a large army before the Fourteenth corps. And yet General Rosecrans was so far from apprehending the actual situation that he sent the following despatch to General Thomas :
CHATTANOOGA, Sept. 12, 1863, 11.15 A. M.
Page 113 - THE ENEMY AT LEE AND GORDON'S MILL
withdrew more through prudence than compulsion. He trusts that our loss is not serious, and that there will be no difficulty in holding the gap. He despatched you last night to communicate with General McCook and call him up if you thought necessary. He trusts this has been done, if not, no time should be lost. * * * * It is very important, at this time, for you to communicate promptly, that the General commanding may know how to manage General Crittenden's corps, which will attack the enemy as soon as it can be gotten in position.
Page 114 - LIFE OF GENERAL GEORGE H. THOMAS.
advance north of the mill. General McCook had crossed Lookout Mountain to Alpine, and General R. B. Mitchell's cavalry - Crook's and McCook's divisions - had reconnoitred far toward Rome and Summerville without finding the enemy. This fact, and the capture of prisoners of Longstreet's corps from Virginia, indicated the presence of Bragg's army north of Alpine. McCook had thereupon thrown his trains back upon the mountain, and having sent a cavalry force towards Lafayette to develop the facts, was, on the 12th, holding his troops in readiness to recross the mountain upon receipt of orders to do so, or in the event of the return of the cavalry with positive knowledge of the concentration of Bragg's army at Lafayette. On the 12th Crittenden's corps took position on the line of the Chickamauga, with Van Cleve's division thrown across that stream on the direct road to Lafayette, in the immediate front of the enemy. And on the day that General Rosecrans proposed that "Crittenden's corps should attack the enemy as soon as it could be gotten into position," General Bragg turned from Thomas to direct Folk's corps and other forces against Crittenden, first to crush his corps, and then to turn again against the Fourteenth. Fortunately for the National army this plan also miscarried, through the default of subordinate commanders. Bragg's order for the movement against Crittenden is subjoined:
HEADQUARTERS ARMY OF THE TENNESSEE. Lafayette, Ga., 6 p. M., September 12.
Page 115 - ENEMY CONCENTRATED FOR BATTLE
Afterwards, Buckner's corps was moved in support. General Bragg thus refers to the movement and its failure: "Early on the thirteenth I proceeded to the front, ahead Buckner's command, to find that no advance had been made on the enemy, and that his forces had formed a Junction and recrossed the Chickamauga. Again disappointed, immediate measures were taken to place our trains and limited supplies in safe positions, when all our forces were concentrated along the Chickamauga, threatening the enemy in front."
Lafayette was five miles distant from Dug Gap, ten miles from Lee and Gordon's mill, eighteen from Alpine, and fifteen from Ringgold. Bragg's army was mainly between Lafayette and Dug Gap on his left, and Lee and Gordon's mill in his front, and hence he held interior lines of extreme shortness for operations against an army divided into three parts.
It is, therefore, demonstrable that had General Thomas moved rapidly on the direct road to Lafayette, through Dug Gap, as ordered, the defeat of his corps, or its capture would have been inevitable, and the fate of that corps would have been the fate of the army. It is accordingly not surprising, that when General Rosecrans had full knowledge of the facts, he frankly stated in his official report that "It was, therefore, a matter of life and death to effect the concentration of the army."
When it was evident that General Bragg's army was concentrated north
of Lafayette, McCook's corps was forty miles distant from Crittenden's
by the nearest road, and the distance from Lee and Gordon's mill, and from
McLemore's Cove to Bragg's army, was less than between the positions of
Thomas and Crittenden, while McCook's corps was much farther from Thomas'
position than from the enemy before Lafayette. But, notwithstanding the
wide separation of the corps, the intervening mountains, and the concentrated
forces of the enemy in' proximity to Crittenden, the Army of the
Page 116 - LIFE OF GENERAL GEORGES H. THOMAS
Cumberland was united in time for battle. In abandoning the offensive from the 13th to the 18th, Bragg lost his best opportunity to overwhelm a single corps. During this time Crittenden's corps stood before his army on the opposite bank of the Chickamauga. Had he moved his army forward, he would have forced this single unsupported corps back upon Chattanooga, or westward upon Lookout Mountain, and while doing this he could have covered his communications through Ringgold to Dalton.
At midnight on the 13th McCook received orders to move two
of his divisions to Thomas' support, and guard his trains with the third.
On the following day the corps moved up the mountain, and on the 17th
it was concentrated in McLemore's Cove. In the meantime the Fourteenth
corps had moved gradually towards Lee and Gordon's mill, to be in readiness
to connect in one direction with Crittenden and in the other with McCook.
The enemy's forces were lying along the line of march on the right, but
not in such strength, at any time, as to arrest the movement of Rosecrans'
forces to the left. In the evening of the 18th General Thomas'
head of column reached Crawfish Springs, and there he received orders to
move to the Chattanooga and Lafayette road, at Kelley's farm, and to connect
his right with Crittenden's left, at Lee and Gordon's mill. This night
march was rendered necessary by the movement of General Bragg's forces
to his right, down the right bank of the Chickamauga, on the l8th. He had
intended to cross that stream and attack General Crittenden on that day,
but he had been disappointed by the unexpected slowness of his forces in
moving to position across the stream, in part resulting from Wilder's resistance.
Bragg had been reenforced until he had ten divisions of infantry, comprised
in five corps of two divisions each. The divisions comprised from three
to five brigades each. He had four divisions of cavalry, two on his right
covering the movement of his forces by that flank, and two on his left,
Page 117 - ROSECRANS' ARMY CONCENTRATED
to hold the gaps in Pigeon Mountain, and if possible, to direct attention from the real movement on the other flank. General Bragg had failed in three distinct efforts to strike the Fourteenth and Twenty-first corps in their isolation, and it was his purpose in moving his army down the Chickamauga and across it, to envelop Crittenden's corps, as the left of the National army. Had Bragg made the attack on the 18th he could have done this, but losing a day he lost the opportunity altogether, although his plan of operations for the 18th was based upon the belief that it was still practicable to move his forces upon General Rosecrans' left flank, at Lee and Gordon's mill, and interposing between the National army and Chattanooga, to drive it back in rout upon the mountain passes.
When the three corps of the Army of the Cumberland were united on the
evening of the 18th it was then practicable to withdraw to Chattanooga,
had General Rosecrans been averse to fighting a battle on the left bank
of the Chickamauga. That stream divided the two armies, and General Bragg
had no thought of crossing where there were opposing forces. A part of
his army had already moved down the stream, and was across far below Lee
and Gordon's mill, and his plan of battle was such as to give Rosecrans
on the night of the l8th the best possible opportunity to withdraw his
army without harm. Rosecrans had command of three roads to Chattanooga,
the Lafayette road, the Dry Valley road, and the one leading along the
eastern base of Lockout Mountain. The two most easterly roads passed through
gaps in Missionary Ridge, and the third passed most of the way between
Lookout Mountain and high hills. These main roads and intersecting roads
would have afforded facilities for rapid movement and easy defense. By
a forced march, on three roads practicable for the movement of troops in
column, the army could have reached Chattanooga by the morning of the 19th,
since the most distant brigade was not more than fifteen
Page 118 - LIFE OF GENERAL GEORGE H. THOMAS
miles from that place. It was not unusual during the war for armies to retreat from the presence of other armies under circumstances less favorable for quick movement than in this case. Had, therefore, General Rosecrans elected to withdraw, he might have lost some of his wagons, but it is highly probable that he could have saved them all. It is certain that withdrawal was practicable, and he accepted battle on the field of Chickamauga from choice, and not from compulsion.
General Thomas reached Kelley's farm with Baird's division about daylight,
and having been informed by Colonel Wilder that the enemy had crossed the
Chickamauga in force the evening before at Reid's and Alexander's bridges,
faced his troops towards these bridges across the roads leading to them.
Wilder's brigade of Reynolds' division had taken position on the west of
the Lafayette road, about half way from Kelley's farm to General Crittenden's
position. General Thomas intended to place the other two brigades of that
division on the right of Baird to connect his right with Wilder's left.
When Brannan's division arrived at Kelley's farm, Thomas posted it on the
left of Baird. Soon after it was reported that there was a brigade of Bragg's
army in proximity, which had been cut off the night before by the burning
of Reid's bridge by Colonel Daniel McCook of the Reserve corps. In hope
of capturing this isolated brigade General Brannan was directed to move
forward on the road to the burnt bridge, to capture the brigade or drive
it back across the Chickamauga. This movement developed the enemy and opened
the battle, at a point far north of the one where General Bragg expected
to take the initiative against General Rosecrans' left flank. Brannan soon
encountered Forrest's cavalry, which was covering the right of Walker's
corps, as that corps, Hood's and Buckner's, and Cheatham's division of
Folk's were moving with a left wheel upon Crittenden. The cavalry having,
after a sharp conflict, given way before Brannan,
Page 119 - CHICKAMAUGA
Bragg moved Walker's corps to Forrest's support. This corps, after a
temporary success against Baird's division was driven back, when other
forces of the enemy were turned to the right. In the meantime the first
divisions engaged on the left of the National army were reenforced, and
from Brannan's initiative both armies extended their lines towards Lee
and Gordon's mill. Early in the day Crittenden had sent a brigade to his
left to develop the enemy, if coming against his position. Soon after,
the battle having opened far to his left, while no enemy was threatening
his position, he sent Palmer's division to General Thomas. This division
went into position to the right of Baird. In the meantime General Rosecrans
had placed General McCook in command of all the troops on the right of
Crittenden, and directed him to send his own divisions to the left as they
should come upon the field. Negley's division at the time was in position
on the Chickamauga and was included with the cavalry in McCook's command.
The first division sent from the right to Thomas was Johnson's division
of McCook's corps, and this division went into line on the left of Palmer.
Soon after, General Reynolds' division extended the line to the right.
Thus five divisions were thrown before the enemy as his line was extended
to his left. The lines of neither army were able to maintain continuity,
and each at times was broken. The battle-field for the most part was thickly
planted with forest trees, which were a barrier to regularity in the movement
of troops and the maintenance of connected lines, in the alternations of
aggression and defense. Gradually, however, with the oft repeated repulse
of the enemy, General Thomas' line of five divisions became continuous
and stable. Having failed to drive Thomas from position. General Bragg
advanced fresh troops - Buckner's corps - towards the unoccupied space
on the right of Reynolds. To meet this effort to divide his army, General
Rosecrans directed Jeff. C. Davis' division of McCook's corps, and
Page 120 - LIFE OF GENERAL GEORGE H. THOMAS
Van Cleve's division of Crittenden's corps, to the right of Thomas' line. These divisions were soon heavily engaged, and Sheridan's division from McCook's corps, and Wood's of Crittenden's were also sent to their support. Later in the day Negley's division of Thomas' corps was also sent to this part of the field. Early in the afternoon General Thomas sent Brannan's division from his extreme left to drive back the enemy who had penetrated the line of battle on Reynolds' right. The enemy's success at this point was the most threatening of the day, but Brannan's timely support restored the connection of Reynolds with the troops on his right.
In this action General Bragg's plan entirely miscarried. Expecting to
move seven divisions of infantry and two of cavalry upon the left flank
of Rosecrans' army at Lee and Gordon's mill, and then unite his entire
army on that flank, the battle was forced upon him so far to the north
that one of Crittenden's divisions had been posted opposite Bragg's centre
and the other two had moved at least a mile to confront the left of his
line of battle. And instead of using the remainder of his infantry against
the front of Crittenden's corps near Lee and Gordon's mill he was compelled
to send it down the Chickamauga to cross in the rear of his other forces.
To the defeat of this plan General Thomas contributed largely. He was sent
to the left by General Rosecrans but, except in compliance with this order,
he was virtually in independent command of more than half of the infantry
divisions of the army. Thomas disposed five divisions for battle, and the
troops under his command formed about five-sevenths of the connected line
of battle, and in transferring Brannan's division from his left to the
right of Reynolds he drove back the enemy after the line of battle had
been pierced. No general, in chief or subordinate command, was ever more
quick or judicious in his dispositions, or more forceful in fighting an
enemy.
Page 121 - NIGHT OF THE NINETEENTH
Late in the evening Thomas retired the left of his line a short distance to better ground, and directed the division commanders to construct barricades of logs in front of their troops. It was so evident that the battle had been indecisive in general issue, that both armies were conscious that the renewal of the conflict was inevitable.
During the night the corps commanders were called together for consultation at the headquarters of the commanding general. At this conference General Thomas was urgent that the right and right centre of the army should be withdrawn to Missionary Ridge and the transverse hills to the right and rear of the centre. The ridge and these hills commanded the Dry Valley road and much of the ground between that road and the one leading to Lafayette by Lee and Gordon's mill. Had this suggestion been adopted the defensive strength of the right would at least have been doubled. The strength of the transverse hills was proved on the following day, when Thomas with a part of the army saved the whole of it. But had the entire right of the army been where he would have placed it on the second day of the battle, neither that part nor any other would have been defeated.
The general trend of Missionary Ridge is north and south, but this ridge
is cut into separate hills and series of hills by deep depressions or gaps.
A long depression stretches from McFarland's house, first to the south
and then to the south-east, and cuts the ridge to its base. Through this
depression runs the Dry Valley road. At McFarland's another gap running
to the east is equally deep. These two gaps isolate a series of hills,
which trend south from McFarland's to Villetoe's house on the Dry Valley
road, and, making nearly a right angle at the latter house, stretch to
the east. On the south of the hills there is first low ground and then
other hills, lower than the main ridge, extending nearly to Widow Glen's
house. On the right side of this road, to one moving south, is Missionary
Page 122 - LIFE OF GENERAL GEORGE H. THOMAS
Ridge; and on the left are the hills which connect themselves almost to Widow Glen's. The right of the army, if it had been withdrawn as General Thomas advised, would have rested on the main ridge and upon the detached hills.
The ridge trending north from the Dry Valley road at Villetoe's, was the position taken by Steedman's, Brannan's and Wood's divisions in the afternoon of the 20th, whose strength was then fully tested. It should be mentioned in this connection that had the right of the army, cavalry included, been retired to these defensive positions, most of the field hospitals would have been entirely uncovered. These hospitals had been established on the 19th, near Crawfish Springs, far in the rear and far to the right of the line of battle on that day. They would have fallen into the hands of the enemy had the right of the army been withdrawn the night of the 19th, but had this been done, they would have been speedily regained as one of the fruits of victory.
In seeming deference to General Thomas' suggestion, General Rosecrans ordered Generals McCook and Crittenden, to withdraw their troops. The former was to establish a new line for the right, and the latter was to place his troops to the left of the new line in reserve. At 11.45 P. M., the following order was given to McCook:
HEADQUARTERS DEPARTMENT OF THE CUMBERLAND,
Page 123 - THE ORDERS FOR THE TWENTIETH
Crittenden was ordered to place his two divisions in reserve to support McCook or Thomas:
HEADQUARTERS DEPARTMENT OF THE CUMBERLAND,
Page 124
All the movements required by General Rosecrans' orders were made during the night. General McCook posted Sheridan's division on the slope of Missionary Ridge to the right and rear of Widow Glen's with Davis' division to the left of Sheridan, while General Crittenden placed Wood's and Van Cleve's divisions still further to the left on the eastern slope of the ridge. Wilder's brigade of mounted infantry of Reynolds' division, by direction of the commanding general, reported to McCook for orders, and this brigade was placed on the right of Sheridan. McCook, in compliance with orders, made his dispositions to command the Dry Valley road, and to hold the gap near Widow Glen's house. Defenses were constructed during the night and early morning which, with the natural strength of the position, gave great firmness to the right flank of the army. But, although four divisions had then been withdrawn nearly a mile, there had been no corresponding recession of Negley's and Brannan's divisions and the right flank of the former was in air and far from supporting forces.
Very early in the morning of the 20th - 6 A. M. - General
Thomas requested that Negley's division should be sent to him to take the
position on the left of Baird which Brannan's division had occupied at
the opening of the battle. Brannan's division was then in line on the right
of Reynolds, where it was needed, and Thomas desired to strengthen his
left flank with Negley's division, anticipating that the battle of the
20th would open at that point.
Page 125 - HE ASKS FOR NEGLEY
At 6 A. M., General Thomas sent the following message to General Rosecrans:
H'DQ'RS FOURTEENTH A. C. DEPT. OF THE CUMBERLAND, Near McDaniels’ House, Sept. 20, 1863 - 6 A. M.
HEADQUARTERS DEPARTMENT OF THE CUMBERLAND, September 20, 1863 - 6.35 A. M.
Page 126 - LIFE OF GENERAL GEORGE H. THOMAS
His two divisions were required by a previous order to extend the line of battle from General Thomas' right to Missionary Ridge, in rear of Widow Glen's, - General Rosecrans' headquarters. General Davis had only two brigades on the field, and had lost about forty per cent. of his men on the 19th. McCook's troops could not form a strong line from Negley's right to the point designated for the right flank, much less from Brannan's right to that point. This order then required that General McCook should move his forces to the left, or use the discretion so plainly given. If this order had been given to General Crittenden, who had Wood's and Van Cleve's divisions in reserve on the eastern slope of Missionary Ridge in readiness to support Thomas or McCook, Negley might have been relieved early in the day and been in position on the left of Baird when the battle opened.
The following extract from the report of General Thomas, in relation to the removal of Negley's division to the left, is subjoined:
"After my return from department headquarters, and about 2 A. M., on the 20th, I received a report from General Baird that the left of his division did not rest on the Reid's Bridge road as I had intended, and that he could not reach it without weakening his line too much. I immediately addressed a note to the commanding general, requesting that General Negley be sent to take position on General Baird's left and rear, and thus secure our left from assault. During the night the troops threw up temporary breastworks of logs, and prepared for the encounter which all anticipated would come off the next day. Although informed by note from General Rosecrans headquarters that Negley's division would be sent immediately to take post on my left, it had not arrived at 7 A. M. on the 20th, and I sent Captain Willard of my staff to General Negley to urge him forward as rapidly as possible, and to point out his position to him."
Lieutenant-General Polk, commanding the right wing of the Confederate
army, was ordered by General Bragg to assault General Rosecrans' extreme
left at dawn on the 20th and his divisions were directed to
attack in turn to
Page 127 - AWAITING ATTACK
the left. Lieutenant-General Longstreet, commanding the left wing, was to attack in the same order as soon as Folk's left division was in motion, "and the whole line was then to be pushed vigorously and persistently against the enemy throughout its extent." But the commander of the right wing was not prompt in compliance and, during his absence from his command, Bragg ordered a reconnoissance, which developed the fact that the road to Chattanooga to the left of Rosecrans' army was open, and this knowledge intensified the eagerness of the enemy to attack and turn Thomas' left flank. The reconnoissance reported by Bragg, and the advance of the enemy on his left mentioned by Thomas, were doubtless identical.
General Thomas had done all in his power to strengthen the point selected by Bragg for his initial attack. Thomas' plan was to place the artillery of Negley's division on the eastern base of Missionary Ridge to the left and rear of Baird's division, so as to sweep the space accessible for a flank movement, and to place Negley's three brigades on the left and in close connection with Baird. With an entire division supported by three batteries of artillery, he believed that the left flank of the army could be held against the attacks of the enemy. But Negley was not permitted by the commanding general to leave position until relieved by other troops. The division at one time was actuall
