Steep though the price was, the gain was great. Not only had they shored up and prolonged Brannan’s overlapped western flank; they also had brought with them from McAfee’s Church a hard-hitting battery of three-inch rifles, which added the weight of their metal to the blue resistance, and no less than 95,000 rounds of small-arms ammunition. This last was in particular demand, because the army’s main ordnance supply train had been involved in McCook’s collapse and flight, and Thomas’s soldiers were burning up what they had on hand at a fearful rate; an Ohio regiment of 535 men, for example, would expend nearly 45,000 rounds of rifle ammunition before the day was over. In the face of such fiery opposition—an average expenditure of better than 80 rounds per man, including casualties—it was no wonder that Longstreet pronounced Johnson’s “key of the battle,” by which the Tennessean meant the hilly spur along whose slopes the east-west Union line was drawn, “a rough one.”
Returning from his conference with the disgruntled Bragg, Old Peter arrived to find Kershaw checked on the right and Johnson and Hindman just going in on the left. Like them, he had thought it probable that a determined nudge would persuade the bluecoats to continue their retreat, but when the second attack was repulsed—disclosing, as he said later, that the defenders were “full of fight, even to the aggressive”—he knew he was in for trouble. Hindman, who had been struck in the neck by a fragment of shell but declined to quit the field, agreed with this revised assessment, subsequently reporting that while he “never saw Confederate soldiers fight better,” he had “never known Federal troops to fight so well.” However, Longstreet wasted no time on regret that Kershaw had jumped the gun, committing his two brigades before the six at the far end of the line were ready, or that Johnson, conversely, had not swept around the open flank before Granger arrived to brace it. Instead, he sent word for them to keep up the pressure on the two extremities while Preston was massing his three brigades, only one of which had seen any action so far in the battle, for an assault on the blue center. Then at last, with Law coming in on Kershaw’s left and Stewart on his right, the second of Old Peter’s clenched-fist blows would dispose of what had survived the devastation of the first.
Shortly before 4 o’clock, Preston—“genial, gallant, lovable William Preston,” Longstreet called the forty-six-year-old Kentuckian, whom he met for the first time this afternoon—got his troops in position, two brigades advanced in echelon and one held in reserve, and sent them forward against the center of Brannan’s line. By now the defenders had improvised breastworks from stones and fallen trees, anything at all that would stop a bullet, so that when the attackers emerged from the woods at the foot of the slope they were met by heavy, well-aimed fire directed confidently at them from the crest ahead. They did not stop or attempt to return this fire until they were within eighty yards of the flame-stabbed smoke that obscured the enemy position. There they halted, exposed as they were, and engaged in a deadly exchange of volleys with the sheltered bluecoats for nearly an hour. “Only new troops could accomplish such a wonderful feat,” a general who opposed them declared; which perhaps was true (Hood’s Texans, for example, prided themselves on knowing when to stand and when to run, and in point of fact had chosen the latter course twice already on this same field, today and yesterday) except that it left out of account the determined example of the officers who led them. The two brigades were commanded by a pair of Alabamians, Brigadier General Archibald Gracie and Colonel John H. Kelly, both of whom had had considerable experience under fire. New York born—he had distinguished kinsmen in the Union ranks—Gracie was thirty, a graduate of Heidelberg and West Point and a merchant in Mobile before secession returned him to the profession for which he had been trained, while Kelly was only twenty-three, having left West Point as a cadet to go with his native state when the war began. Both had risen fast and far, but strictly on ability, beginning respectively as an infantry captain and an artillery lieutenant; Kelly, who had soldiers under him better than twice his age, had commanded a battalion at Shiloh, a regiment at Perryville and Murfreesboro, and now a brigade at Chickamauga, which would earn him a wreath for his three stars and make him the youngest general in the army. So led, Preston’s two committed brigades stood their ground and took their punishment, losing 1054 of their 2879 effectives in the process, but fixing the Federals in position while the divisions on their left and right were heartened by their example and Breckinridge finally got the twelve-gun battery posted near the junction of the two wings. Even Polk, across the way, came alive at last in response to the sustained uproar of the volleys Gracie’s and Kelly’s men were exchanging with their opponents, and sent word for his division commanders to match the pressure, there on the east, that Longstreet was exerting from the south.
No one knew better than Thomas, wedged as it were between anvil and sledge, that once the Confederates achieved this concert of action, east and south, the issue could not long remain in doubt. Moreover, though the two armies had begun the day with equal numbers and though each would suffer casualties of about one third its total strength before the battle ended, another third of the blue army had fled the field by early afternoon, which left Thomas with only about one third of the original Union force, as compared to Bragg’s two thirds; in short, after succeeding by default to the command, the Virginian faced odds of roughly two to one, with the additional disadvantage of being pressed from two directions, in each of which the enemy strength was about equal to both Federal wings combined. He knew that under these circumstances he would have to withdraw eventually, but he hoped to prolong the struggle until he could do so under cover of darkness. As late as 4 o’clock, when Garfield arrived with his absent chief’s suggestion for “retiring to a position in the rear,” Thomas declined even to consider a retreat by daylight. “It will ruin the army to withdraw it now,” he said. “This position must be held until night.” Before another hour had passed, however, with Preston clawing at him from below and the other rebel divisions of both wings increasing the tempo of their action and inching closer to his lines, he saw that to attempt a much longer delay would be to risk a breakthrough which would be even more costly to him than a daylight disengagement, dangerous though such a maneuver was said to be in all the tactics manuals. Accordingly, about 5 o’clock, while the sun was still an hour high, he settled on a plan for withdrawal, first on the left, where the pressure was less severe, and then on the right. The divisions along the north-south line would pull out in reverse order, first Reynolds, then Palmer, then Johnson, each passing in rear of the unit on its left; Baird would be last and would serve as rear guard on the march to McFarland’s Gap and Rossville, where a new line of battle would be formed to discourage pursuit beyond that point. Similarly, Brannan and Steedman, together with the brigades that had been used to reinforce them, would fall back in sequence from the east-west line, following the same route to comparative safety. Or so at any rate Thomas hoped, knowing full well that the execution of the orders designed to bring this about would be difficult at best.
Reynolds began the movement at 5.30, and for the next two hours, from broad daylight into darkness, the battle raged with a new intensity, a new sense of urgency, as various units of both armies, obliged by the attendant confusion to operate more or less on their own, attempted on the one hand to achieve, and on the other to forestall, deliverance from slaughter. Thomas had improvised well, but in a situation so fluid that orders no longer applied by the time they were issued, let alone received, success or failure depended almost entirely on the naked valor of his infantry and the ability of his subordinate commanders to maintain control of troops who, after all, were running for their lives. In this regard, Reynolds was outstanding. Marching north on the LaFayette Road, in rear of the other three divisions, he reached the extreme left to find that Liddell had outflanked Baird and was about to strike the Union line end-on. Instead of turning west for McFarland’s Gap, as ordered, the Kentucky-born Hoosier launched a savage counterattack that drove the would-be flanke
rs back and kept open the path of retreat for the other three divisions, who were themselves under mounting pressure from Breckinridge and Cleburne. Though they lost heavily in the withdrawal, being obliged to abandon their wounded along with their dead, the four divisions managed to effect a disengagement by moving rapidly westward, outstripping their pursuers in the race for Missionary Ridge, behind which the sun had set by now. Brannan and Steedman had a harder time of it: particularly the former, who was required to hold his ground while the latter began his withdrawal in the wake of the left-wing divisions which had passed across his rear. When Steedman pulled back, Hindman’s and Johnson’s men boiled over the ridge in close pursuit, and Preston committed his third brigade, which plunged through the newly opened breach and then turned right to fall on Brannan’s unprotected flank. Three regiments were captured in one swoop, two from Michigan and one from Ohio, and the battle abruptly disintegrated, here on the right as it had on the left, into a race. That Brannan’s survivors won it was due in large part to a pair of Indiana regiments from Reynolds’ division. Coming upon a broken-down ammunition wagon, abandoned by a teamster who had fled with his mules in the earlier rout, the Hoosiers filled their empty cartridge boxes and countermarched, under direct orders from Thomas himself, to serve as rear guard and cover the final stage of the retreat. This they did, checking the butternut pursuers with volleys fired blind in the gathering darkness; after which they once more faced about and took up their westward march, the last blue troops to leave the field.
In some ways, though, the hardest part of the battle still lay before them; for they marched now, down the dark valley from McFarland’s Gap to Rossville, with the taste of defeat bitter in their mouths and a great weariness in their limbs. Perryville and Stones River had been bad enough, but the fact that they had remained in control of both those fields when the smoke lifted had given their generals and journalists the basis for a claim to victory. Not so here. This was absolute, unarguable defeat, and as such it was depressing beyond anything they had ever known. “Weary, worn, tired and hungry,” a captain in a veteran regiment later wrote, “we sullenly dragged ourselves along, feeling a shame and disgrace that had never been experienced by the Old Sixth before.” Those who fell out of the column because of wounds or exhaustion were left to their own inadequate devices by those who had the strength to keep going. Behind them, beyond the intervening ridge, they could hear the rebels celebrating their triumph with loud yells. Another officer in the retreating column, First Lieutenant Ambrose Bierce, a topographical engineer with Hazen, thought the sound “the ugliest any mortal ever heard.” Presently, however, there was a stretch of road well down the valley “across which that horrible yell did not prolong itself,” he added, “and through that we finally retired in profound silence and dejection, unmolested.”
Back on the field of Chickamauga, their spirits lifted by the release of tension, the Confederates kept yelling, despite an almost equal physical weariness, long after their adversaries were out of earshot. As Longstreet put it, “The Army of Tennessee knew how to enjoy its first grand victory,” beginning at the moment when the two wings came together, there on the reverse slopes of the hilly spur from which the Yankees had just been driven, and continuing into the night with “a tremendous swell of heroic harmony that seemed almost to lift from their roots the great trees of the forest.” Harvey Hill declared years later that the cheers “were such as I had never heard before, and shall not hear again.” In point of fact, along strictly practical lines, the victors had more to whoop about than anyone yet knew. Afterwards, when the field had been gleaned, Bragg would report the capture of more than 8000 prisoners, 51 guns, and 23,281 small arms, together with 2381 rounds of artillery ammunition and 135,000 rifle cartridges. The multipaged scavenger list, certified by the chief of ordnance, would include such items as 35 pounds of picket rope, 365 shoulder straps, and 3 damaged copper bugles, as well as “wagons, ambulances, and teams, medicines, hospital stores, &c., in large quantities.” It was, in brief, the largest haul ever made by either side on a single field of battle. For the present, however, all the exultant graybacks knew was that they had scored a triumph of considerable proportions, and they did not delay their celebration to wait for the particulars of its scope.
Nor did others who were not there to see for themselves. After the recent and apparently interminable sequence of knee-buckling reverses, soldiers and civilians throughout the nation were elated by the news from North Georgia, which seemed to them to bear out earlier predictions that the northern armies would find what true resistance meant when they approached the southern heartland. “The effects of this great victory will be electrical,” a Richmond clerk recorded in his diary. “The whole South will be filled again with patriotic fervor, and in the North there will be a corresponding depression.… Surely the Government of the United States must now see the impossibility of subjugating the Southern people, spread over such a vast expanse of territory, and the European governments ought now to interpose and put an end to this cruel waste of blood and treasure.”
In war, as in love—indeed, as in all such areas of so-called human endeavor—expectation tended to outrun execution, particularly when the latter was given a head start in the race, and nowhere did this apply more lamentably, at any rate from the Richmond point of view, than in the wake of Chickamauga, probably the greatest and certainly the bloodiest of all the battles won by the South in its fight for the independence it believed to be its birthright. Harvey Hill said later that he had “never seen the Federal dead lie so thickly on the ground, save in front of the sunken wall at Fredericksburg.” In point of fact, though Hill may not have seen them on his quarter of the field, the Confederate dead lay even thicker; but in any case, now that the Yankees were on the run, he and the other two lieutenant generals, commanding the two wings, were altogether in favor of a rapid and slashing pursuit of the beaten foe. Though Longstreet called a halt in the dusk that followed his second breakthrough, it was for the same purpose as the halt that had followed his first at midday; namely, to consolidate his forces for the delivery of another heavy blow. “As it was almost dark,” he afterwards reported, “I ordered my line to remain as it was, ammunition boxes to be filled, stragglers to be collected, and everything [placed] in readiness for the pursuit in the morning.” Polk, perhaps aware that he had done less to win the victory up to now, prepared to do more by sending out scouts to look into the possibility of continuing the slaughter of the vanished enemy. Later, when the scouts returned to report that the bluecoats had not slacked their headlong retreat, the bishop rode to headquarters and informed Bragg—whom he roused from bed, much as Old Peter had done at about the same hour the night before—“that the enemy was routed and flying precipitately from the field, and that then was the opportunity to finish the work by the capture or destruction of [Rosecrans’] army, by prompt pursuit, before he had time to reorganize or throw up defenses at Chattanooga.” So an aide who rode with him testified: adding, however, that “Bragg could not be induced to look at it in that light, and refused to believe that we had won a victory.”
It was true that the commanding general had received no formal notification of the outcome of the battle, but only because this had seemed to his subordinates a highly superfluous gesture. (“It did not occur to me on the night of the 20th to send Bragg word of our complete success,” Longstreet explained years later. “I thought that the loud huzzas that spread over the field just at dark were a sufficient assurance and notice to anyone within five miles of us.”) On the other hand, if what he wanted was an eyewitness who could testify to the behavior of the Federals after they reached the far side of Missionary Ridge—beyond which, conceivably, they might rally and lie in wait for him to commit some act of rashness—that too was available, soon after first light next morning, in the form of a Confederate private who had been captured the previous day, then escaped amid the confusion of the blue retreat, and made his way back to his outfit before dawn. When he to
ld his captain of what he had seen across the way—for instance, that the Unionists were abandoning their wounded as they slogged northward, intent on nothing but their flight from fury—he was taken at once to repeat his story, first to his regimental and brigade commanders, then to Bragg himself. The stern-faced general heard him out, but was doubtful, if not of the soldier’s capacity for accurate observation, then at any rate of his judgment on such a complicated matter. “Do you know what a retreat looks like?” he asked sharply, fixing the witness with a baleful glare. Irked by his commander’s mistrust, the man replied with words that endeared him to his comrades, then and thereafter, when they were repeated, as they often were, around campfires and at future veteran gatherings. “I ought to, General,” he said; “I’ve been with you during your whole campaign.”
