Keeping his main body well back from the river to screen his true intention, he demonstrated upstream with three brigades. Every night they lighted bonfires in rear of all possible crossings, from opposite Chattanooga itself clear up to Washington, a distance of forty miles, and while special details sawed the ends from planks and threw the scraps into creeks flowing into the Tennessee, others pounded round the clock on empty barrels in imitation of shipyard workers, thereby encouraging rebel scouts across the way to report that boats were being constructed for an amphibious assault somewhere along that stretch of the river. On August 21, by way of adding punch to the show, a battery went into action on Stringer’s Ridge, directly across from the city, throwing shells into its streets and scoring hits on two steamboats at its wharf, one of which was sunk and the other disabled. Bragg’s reaction was to withdraw the brigade from the north-bank bridgehead he had been holding all this time near Bridgeport, fifty miles downstream, and before the week was out a crossing by the mass of the blue army was underway in that vicinity: by Thomas at Bridgeport itself, where pontoons were thrown in replacement of the burned railroad bridge: by McCook, twelve miles below at Caperton’s Ferry: and by Crittenden, ten miles above at Shellmound, which was twenty air-line miles due west of Chattanooga and twice that far by river. None of the three met any substantial resistance, so well had the upstream deception served its purpose. Except for Granger’s one-division reserve corps, on guard at the Stevenson depot of supplies, and the three detached brigades, which kept making threatening gestures to fix Bragg’s attention northward, Rosecrans had his whole army across the Tennessee by September 4, including all his artillery and trains loaded with ammunition enough for two great battles and rations for better than three full weeks, in case he remained that long out of touch with his base on the north bank. The main thing, as he saw it, was to keep moving and move fast. And that he did.
It took some doing, for the terrain was rugged; but Old Rosy had planned for that as well, directing the formation of company-sized details equipped with long ropes for hauling guns and wagons up difficult grades when the mules faltered. Perpendicular to his line of march, the three lofty ridges—actually long, narrow mountains, with deep valleys intervening—were Raccoon Mountain, Lookout Mountain, and Missionary Ridge. Lookout, which extended all the way to the bend of the river just below Chattanooga, was penetrated by only two gaps: Stevens Gap, 18 miles southwest of the city, and Winston Gap, 24 miles farther down. Rosecrans planned to use them both for a fast march eastward, sending Crittenden directly along the railroad, around the sheer north face of the mountain and into the city, which Bragg would probably evacuate when he learned that the other two corps were moving through the passes in his rear—McCook by way of Winston Gap, then around the lower end of Missionary Ridge, toward Alpine and Summerville, and Thomas by way of Stevens Gap, which also pierced Missionary Ridge within a dozen miles of LaFayette—for a blow at his vital and vulnerable rail supply line from Atlanta. Here again there were drawbacks, theoretical ones at any rate. The two outer columns, Crittenden’s and McCook’s, would be more than forty miles apart, and neither would be within a day’s march of Thomas in the center; Bragg might concentrate and strike at any one of the isolated three. But this too had been foreseen and guarded against by sending all but one brigade of the cavalry with McCook—who seemed most susceptible in that regard, being on the remoter flank—while the remaining brigade preceded Crittenden, ready to give warning in case such a threat developed. The main thing was speed, and this assured just that. Rosecrans rode with the trooperless middle column, not only to keep in closer touch with all three of his chief lieutenants, but also to act as a goad to Thomas, who had many admirable qualities but was known to be somewhat lethargic on occasion.
Proud in the knowledge that they were the first Federals to penetrate this region since the beginning of the war, the men reacted with enthusiasm to the march, particularly when they saw spread out before them such vistas as the one unrolled from atop Raccoon Mountain. “Far beyond mortal vision extended one vast panorama of mountains, forests, and rivers,” an Illinois veteran later wrote. “The broad Tennessee below us seemed like a ribbon of silver; beyond rose the Cumberlands, which we had crossed. The valley on both sides was alive with the moving armies of the Union, while almost the entire transportation of the army filled the roads and fields along the Tennessee. No one could survey the grand scene on that bright autumn day unmoved, unimpressed with its grandeur and the meaning conveyed by the presence of that mighty host.” Presently word came from Crittenden that Bragg had apparently had a similar reaction to the presence of all those bluecoats in his rear; for when the Kentuckian drew near Chattanooga on September 8 he learned that the Confederates were in mid-evacuation, and next morning, as the tail of the gray column disappeared through Rossville Gap and behind the screen of Missionary Ridge, the city fell without the firing of a shot. Rosecrans passed the word to the troops of the central column, who did their best to rock Lookout with their cheers as they slogged through Stevens Gap.
Simultaneously, scores of butternut deserters began to filter into the Union lines with reports of Bragg’s demoralization. He was in full flight for Rome or perhaps Atlanta, they declared, quite unmanned by this latest turning movement and in no condition to resist an attack if one could be thrown at him before he got there. Convinced that he had acted wisely in accepting the risk of dispersion for the sake of speed, Old Rosy urged his cheering soldiers forward, intent on giving the panic-stricken rebels what the deserters said would amount to a coup de grâce.
Rosecrans was partly right about Bragg, but only up to a point a good way short of the whole truth. The Confederate commander had been outsmarted, and he had fallen back in haste, even in some disorder, to escape the closing jaws of the Federal trap; but that was as far as it went. He was not retreating now, nor was he avoiding a fight. Rather, he was in search of one, although on different terms, having by now devised a trap of his own. As for the butternut scarecrows who had come stumbling into the northern lines, peering nervously over their shoulders and babbling of demoralization in the fleeing press of comrades left behind, Old Rosy would have done well to bear in mind some words one of his young staffers wrote years later: “The Confederate deserter was an institution which has received too little consideration.… He was ubiquitous, willing, and altogether inscrutable. Whether he told the truth or a lie, he was always equally sure to deceive. He was sometimes a real deserter and sometimes a mock deserter. In either case he was sure to be loaded.” In the present instance, a considerable number of them were indeed “loaded,” being scouts sent forth by Bragg himself, who had chosen them for their ability to be convincing in misrepresentation of the true state of affairs in the army that lay in wait for the exuberant bluecoats, just beyond the last of the screening ridges.
Bragg’s present aggressiveness had come only after six weeks of uncertainty and confusion following his retreat across the Tennessee. Hearing from Adjutant General Cooper on August 1 that the government was anxious to reinforce him with most of Johnston’s army, on condition that he recross the river for an attack on Rosecrans, he replied next day that he was willing, provided “a fight can be had on equal terms.” But three days later he withdrew the offer. “After fully examining all resources,” he wired, “I deem them insufficient to justify a movement across the mountains.” He meant the Cumberland Plateau, which he had just traversed and which by then was serving Rosecrans as a screen to hide his preparations for pursuit. He did not like having it there at all; he wished it could be abolished. “It is said to be easy to defend a mountainous country,” he complained to one of his corps commanders, “but mountains hide your foe from you, while they are full of gaps through which he can pounce upon you at any time. A mountain is like the wall of a house full of rat holes. The rat lies hidden at his hole, ready to pop out when no one is watching. Who can tell what lies hidden behind that wall?” Respectfully, while in this frame of mind, he informe
d Richmond that he declined to plunge his army into “a country rugged and sterile, with a few mountain roads only by which to reach a river difficult of passage. Thus situated,” he explained, “the enemy need only avoid battle for a short time to starve us out.” But he added, by way of final encouragement: “Whenever he shall present himself on this side of the mountains the problem will be changed.”
On the strength of this last, though disappointed that Bragg was unwilling to take the offensive, the authorities decided to reinforce him anyhow. In point of fact, even aside from the evidence that Joe Johnston seemed determined to do nothing with the troops standing idle in Mississippi all this time, they had no choice; repulses or surrenders at Gettysburg and Vicksburg, Helena and Port Hudson, plus the loss of Middle Tennessee and Morgan’s raiders, all within a single month, had caused them to question whether the South could survive another large-scale defeat this soon, particularly one that would swing ajar the gateway to its heartland. Informed of Richmond’s decision, Bragg set about reorganizing his army so as to incorporate without delay the new brigades and divisions about to join or rejoin him from various directions. Indeed, reorganization had already begun on a limited scale. Hardee having been detached in mid-July to take over the mutinous remnant of Pemberton’s band of parolees awaiting exchange at Demopolis, the irascible and highly competent D. H. Hill, promoted to lieutenant general subject to congressional approval, had come from North Carolina to replace him. Likewise the dapper and experienced, if disgruntled, Tom Hindman arrived in mid-August from the Transmississippi, and a place was made for him by transferring the less distinguished Withers to an administrative post in his native Alabama. Soon afterwards Buckner was ordered to evacuate Knoxville, and having moved southwest to Loudon, where he burned the railroad bridge across the Tennessee, he continued his march to the Hiwassee, less than forty miles from Chattanooga. There he stopped, for the time being, under orders to contest an advance by Burnside, if one developed, and stand ready to join Bragg on short notice if one did not. By that time Breckinridge had arrived with the first of two divisions being sent from Mississippi. He rejoined his old corps, formerly Hardee’s, and Major General A. P. Stewart’s division was detached from Hill to be combined with Buckner’s and thus form a new third corps under the Kentuckian, who was summoned from the Hiwassee, Burnside having turned his attention elsewhere. When W. H. T. Walker joined Bragg with the second of the two divisions from Johnston, another division was organized by detaching and combining brigades from divisions already present, thus providing a fourth corps under his command. Practically overnight—that is, within a ten-day period extending from late August into early September—the Army of Tennessee had grown from two to four corps, each with two divisions, and a total strength of about 55,000 effectives, including cavalry.
Having in these eight infantry divisions 26 brigades with which to oppose 33 brigades in the eleven Federal divisions—considerably better odds, after all, than the ones he had prevailed against at Murfreesboro—Bragg developed, in the course of the reorganization of his expanded army, strong hopes of being able to defeat his adversary in pitched battle. He was not so sure, however, that this was what it would come to here, any more than it had at Tullahoma, where he had been outmaneuvered and given no real chance to defend a position he had been determined not to yield without a fight. In fact, there were signs that it would not. All this time Rosecrans had been demonstrating as if for a crossing well above Chattanooga, a repetition of the strategy that had won him Middle Tennessee, and Bragg had been reacting fretfully. Harvey Hill, for one, was quite unfavorably impressed. The junior lieutenant in Bragg’s battery a dozen years ago in Texas—George Thomas, now commanding a blue corps across the way, and John Reynolds, recently killed at Gettysburg, were the other two lieutenants—Hill had looked forward to the reunion at Chattanooga, but was received with none of the warmth he had expected from his chief. “He was silent and reserved and seemed gloomy and despondent,” Hill said later of his fellow North Carolinian. “He had grown prematurely old since I saw him last, and showed much nervousness.” Moreover, as the newcomer learned from those who had been with the army all along, this was not entirely due to worry about his opponent on the far side of the river. “His relations with his next in command (General Polk) and with some others of his subordinates were known to be not pleasant. His many retreats, too, had alienated the rank and file from him, or at least had taken away that enthusiasm which soldiers feel for the successful general, and which makes them obey his orders without question.” Fresh from the East, where he had been impressed by Lee’s great daring, always based on sound knowledge of the enemy’s dispositions, Hill was shocked by Bragg’s apparent ignorance of the enemy’s whereabouts and movements, which resulted in his maintaining a supine attitude while waiting for Rosecrans to show his hand. It was Hill to whom he described the Cumberlands as “the wall of a house full of rat holes,” and Hill afterwards recorded that he “was most painfully impressed with the feeling that it was to be a haphazard campaign on our part.”
However that might be, and it was as yet no more than an impression, it presently developed that Bragg had been quite right to suspect that Old Rosy was groping elbow-deep in his bag of tricks. No sooner was the Confederate reorganization completed than Bragg learned that the Federals were not only over the river, well downstream, but were also far in his rear, crossing Lookout and the other north-south Georgia ridges for a strike at the rail supply line whose loss would mean starvation for the defenders of Chattanooga. Determined not to be trapped as Pemberton had been at Vicksburg, he promptly evacuated the city and fell back southward through Rossville Gap to a position from which to block the continued advance of the three blue columns when they came around and over Missionary Ridge. His left was at LaFayette, two dozen miles from Chattanooga, and his right at Lee & Gordon’s Mill, twelve miles north, where the road from Rossville crossed Chickamauga Creek. Walker held the former, Polk the latter, and Hill and Buckner were posted in between, confronting the westward loom of Pigeon Mountain, a crescent-shaped spur of Lookout Mountain which inclosed the lower end of Missionary Ridge and its eastern valley, a cul-de-sac known locally as McLemore’s Cove. Bragg saw in this the trap he had been seeking, the trap he had encouraged Rosecrans to enter by sending out loaded deserters to dispel the Ohioan’s native caution and hasten his march with the promise of an easy triumph over a demoralized opponent. Wheeler and Forrest, who had been called in and now were operating respectively on the immediate left and right, toward Alpine and Rossville, were instructed to impede the advance of McCook and Crittenden from Winston Gap and Chattanooga. This would leave the balance of the army, some 40,000 infantry and artillery, free to concentrate against Thomas, who had a total of 23,000 effectives, and destroy him there in the fastness of McLemore’s Cove; after which the victors would turn on either or both of the remaining enemy columns, still well beyond supporting distance of each other, and administer the same annihilation treatment. Bragg so ordered on the evening of September 9, shortly after receiving from his scouts, civilian as well as military, reports that Thomas’s lead division had entered the cove that afternoon and made a sundown camp on upper Chickamauga Creek.
His plan combined the virtues of simplicity and power, and his orders were issued with the coolness of a gambler holding four aces against a splurger whose overconfidence had been nurtured by an inordinate run of luck. While Cleburne’s division of Hill’s corps attacked due west through Dug Gap, corking the Pigeon Mountain outlet and fixing the bluecoats in position, Hindman’s division of Polk’s corps would move southwest from Lee & Gordon’s Mill, up Chickamauga Creek, sealing the mouth of the cul-de-sac and striking the enemy flank and rear. Basically, the operation was intended to be like that of? meat-grinder, and if Thomas reinforced his lead division in the cove, so much the better; Breckinridge would be in support of Cleburne, Cheatham of Hindman, and the Federal reinforcements would only give them that much more meat to grind. Hindman set ou
t an hour after midnight, September 10, and halted at dawn, four miles short of contact, waiting to hear from Cleburne. He had a long, tense wait. Finally a message came from Hill, protesting that he had not received his orders till after daylight, that Cleburne himself was sick in bed, with four of his best regiments absent on other duties, and that the proposed attack was risky in the first place, since Thomas had probably sent his lead division forward “as a bait to draw us off from below.” In short, Cleburne would not be coming; not this morning at any rate. Later in the day, while still maintaining his indecisive position short of contact, Hindman received a message from Bragg, urging him to finish up his work in the cove as quickly as possible, because Crittenden’s corps was on the march from Chattanooga by way of Rossville Gap, directly in his rear. This added fright to confusion, and after remaining all night in a position which he judged perilous in the extreme, the veteran of Prairie Grove decided next morning to withdraw the way he had come. By now, though, Bragg had sent Buckner to his support, with orders to force the issue promptly, and Cleburne was through Dug Gap; so Hindman returned southward. But when the two gray forces came together that afternoon in McLemore’s Cove there was nothing blue between them. Thomas at last had spotted the danger, despite his lack of cavalry, and withdrawn to the far side of Missionary Ridge.
