Secrecy being an all-important element of guile, he played his cards close to his vest. He said nothing of the particulars of his plan to either his subordinates or his superiors when, on June 16, he confided to the latter—prematurely, as it turned out—that he would advance in “say five days.” Not even on June 24, in the telegram sent at 2.10 in the morning to announce that the army would be on the march within fifty minutes, did he say in what direction or strength the movement would be made. He was taking no chance on a Washington leak, even at that late hour, though of course his corps and division commanders had been informed of their share in the grand design and told to have their units deployed on schedule. Gordon Granger, with the one division remaining in his reserve corps after heavy detachments for garrison duty at Nashville and other points, began his march down the pike toward Shelbyville, preceded by a full division of cavalry, with instructions to kindle campfires on a broad front every night in order to encourage Polk, and therefore Bragg, to believe that this was the Federal main effort. Crittenden, one of whose three divisions remained on guard at Murfreesboro, began to execute the transparent feint eastward in the direction of McMinnville with the other two, preceded by a brigade of cavalry. George Thomas, whose four-division corps was much the largest in the army, took up the march for Hoover’s Gap and Manchester, followed by Alex McCook, who had been told to make a disconcerting attack on Liberty Gap with one of his three divisions, thereby fixing Hardee in position at Wartrace, just beyond the gap, while Thomas circled his flank to threaten his rear. As usual, with Old Rosy in charge, no detail had been neglected. The foot soldiers were massed in their respective assembly areas, all ten divisions of them under carefully briefed commanders, and staff officers checked busily to see that all was as it should be, not only among the combat elements, but also in the rear echelon, including the various supply trains loaded with rations for twelve days. Nothing that could be calculated had been overlooked. Half the beef had been salted, for example, and loaded in wagons for ready distribution, while the other half was on the hoof: self-propelled, so to speak, for speed and ease of transportation.
Whereupon, just as the troops stepped out in the predawn darkness, beginning to weave the network of marches designed to accomplish Bragg’s discomfiture, something uncalculated—indeed, incalculable—occurred. What Rosecrans later described as “one of the most extraordinary rains ever known in Tennessee at that period of the year” began to fall; “no Presbyterian rain, either,” an Illinois soldier called it, “but a genuine Baptist downpour.”
That was only the beginning. Crittenden afterwards maintained that, from this day forward, it “rained incessantly for fifteen days,” and reports by lesser commanders bore witness to the difficulties involved. “Rain poured in torrents the entire night”; “Train not up in consequence of difficult traveling”; “Wet weather all day”; “Troops and animals much jaded.” There was small comfort in knowing that the rain also fell on the rebels, but the men derived a kind of bitter satisfaction from the knowledge that they could learn to put up with almost anything. “It rained so much and so hard,” one declared, “that we ceased to regard it as a matter of any consequence and simply stood up and took it, without attempting to seek shelter or screen ourselves in the least. Why should we, when we were already wet to the skin?” Besides, they had been heartened at the outset, before the fields and secondary roads were churned shin-deep in mud, by reports of a solid achievement that opened the way for the column under Thomas, who had been given the leading role in the present act of the drama Rosecrans was directing. More specifically, the accomplishment had been scored by Colonel John T. Wilder’s brigade of Major General J. J. Reynolds’ division.
It had been Wilder, a former Indiana industrialist, who surrendered Munfordville to Bragg, together with more than 4000 soldiers and 10 guns, as an incident of the Confederate advance into the Bluegrass region of Kentucky the previous September. The memory of that still rankled, and Wilder and his command, two regiments of fellow Hoosiers and two from Illinois, exchanged soon after their captors released them on parole—though not in time to fight at Perryville—were determined to make the rebels pay for that indignity. Just now they were in an excellent position to do so, for they were the lead element of the column that would deliver the main effort intended to throw Bragg into confusion. Moreover, they were superbly equipped for the work at hand, both in mobility and firepower, partly as a result of efforts by Rosecrans and partly as a result of efforts of their own. Short of cavalry, the army commander had mounted two of his infantry brigades, and one of these was Wilder’s, who had also seen to it that his troops were armed with seven-shot Spencer carbines, the first unit in the West to be so accoutered. He had done this by signing a personal note upon which security bankers in his home town of Greensburg had a vanced funds for purchase of the Spencers, the men having agreed to periodic deductions from their pay in order to reimburse their commander, pending their own reimbursement by the army once the red tape had been cleared away. So armed and mounted, 2000 strong, they left their camps above Murfreesboro at exactly 3 a.m. and by midmorning were herding enemy pickets into the northern mouth of Hoover’s Gap, the prompt seizure of which was prerequisite to the success of the whole campaign. Wilder did not hesitate in fear of a trap or ambush, but plunged straight ahead through the three-mile-long pass with all the strength and speed he could muster, his mounted infantry driving the graybacks before them with the considerable help of their rapid-fire weapons. The works at the southern end of the gap were taken in a rush, together with the silk-embroidered colors of the 1st Kentucky Infantry, an elite Confederate outfit. Unlimbering their six guns, the Hoosiers and Prairie Staters broke up a savage counterattack and held the pass alone until the other two brigades of the division came plodding up to reinforce them, swinging their caps and cheering despite the rain. As a result of Wilder’s daring and resolution, and at a relatively minor cost of 14 killed and 47 wounded, the way now lay open for an advance by Thomas around Hardee’s flank and into his rear.
Bragg personally was not in good shape, either physically or mentally, for resisting the strain his opponent was about to apply as a test of his staunchness and perception. He had weathered the criticisms leveled at him by his chief subordinates, the steady depletion of his army by detachments ordered to Pemberton and Johnston, and the near-fatal illness of his wife, only to undergo a siege of boils which, by his own admission, had culminated in “a general breakdown” of his health by early summer. None of these troubles, particularly the last, had had the effect of sweetening his temper, lengthening his patience, or enabling him to abide the shortcomings of his associates, most of whom he considered unfit for their present duties. Unfortunately, too, these various woes and discomforts had served to increase, if anything, his accustomed savagery of looks and reflexes. “This officer in appearance is the least prepossessing of the Confederate generals,” the ubiquitous Colonel Fremantle had recorded in his diary when he visited Bragg that spring, en route from Texas to Richmond. “He is very thin; he stoops; and has a sickly, cadaverous, haggard appearance; rather plain features, bushy black eyebrows which unite in a tuft on the top of his nose, and a stubby, iron-gray beard; but his eyes are bright and piercing. He has the reputation of being a rigid disciplinarian, and of shooting freely for insubordination. I understand he is rather unpopular on this account, and also by reason of his occasional acerbity of manner.”
Not that the Tennessee commander lacked grounds for pride in what he and his men had accomplished during their sojourn in the lush Duck River Valley. After all—though admittedly it was with the determined co-operation of an adversary who resisted all urgings to advance—he had held his ground and managed to feed and refit his badly outnumbered army in the process. “Our transportation is in fine condition,” Polk was writing home, “horses and mules all fat, and battery horses and batteries in fine condition. The troops have plenty of clothes and are well shod. We have plenty of food also, and so far
as the fields before us are any indication, there never was such a wheat harvest.” Moreover, despite the permanent loss of some 6000 men at Murfreesboro and the detachment since of at least that many more, including Breckinridge’s whole division, Bragg’s mid-June strength of 46,250 effectives (for once in this war, at any rate, a Union commander had underestimated the force arrayed against him) was appreciably greater than it had been before New Year’s. Primarily he had accomplished this by rigid enforcement of the conscription laws in the region threatened by a Federal advance, for he knew only too well that this might be his last chance to get at this particular reservoir of manpower, Davis having given him permission beforehand to fall back across the Tennessee as soon as he judged the pressure against his front to be insupportable. Rosecrans, however, for all his underestimation of Bragg’s strength, had exerted almost no pressure at all in the past five months; so that Bragg had had ample opportunity to drill and condition his soldiers for the work that lay ahead. This was the sort of thing he did best, and the results had been gratifying. Even Fremantle, a product of the most rigid sort of training, admitted that the citizen soldiers “drilled tolerably well, and an advance in line was remarkably good.” That was high praise indeed from an officer of the Coldstream Guards, though he could not repress a shudder on observing that some of the men had removed their jackets because of the heat and marched past the reviewing stand in shirt sleeves. When he expressed a desire to see them “form squares,” he was told by his host that they had not been taught this maneuver, since “the country does not admit of cavalry charges, even if the Yankee cavalry had the stomach to attempt it.” Similarly, he noted that the absence of the bayonet as a standard piece of equipment was a matter of small concern to the troops, “as they assert that they have never met any Yankee who would wait for that weapon.” This last, of course, was far from true—as any stormer of the Hornets Nest or the Round Forest could have testified—but it was a measure of the men’s high spirits that they made the claim to the credulous Englishman, who closed the account of his visit by remarking that “the discipline in this army is the strictest in the Confederacy.”
In round numbers, 32,000 infantry and artillery were with Polk and Hardee on the Shelbyville-Wartrace line, while 14,000 cavalry were with Wheeler and Forrest, strung out for thirty miles east and west, respectively, with headquarters at McMinnville and Columbia. These 46,000 effectives, comprising the Army of Tennessee, did not include some 15,000 under Buckner, who was charged with the defense of Knoxville against Burnside. That general, what time he was not fulminating against the Copperheads in his rear, was known to be preparing for an advance by the Army of the Ohio, though he had been crippled even more sorely than Bragg by detachments sent to Mississippi. To help discourage the threat in that direction, and also to continue the harassment of his Middle Tennessee opponent’s lines of supply, Bragg had recently agreed to a proposal by John Morgan that he stage another of his famous “rides” into Kentucky with his 2500 Bluegrass troopers. Nettled by the defeats suffered in late March and early April at Milton and Liberty—he had in fact accomplished nothing significant since his spectacular Christmas Raid, hard on the heels of his marriage to Mattie Ready—Morgan had sought permission to extend his field of operations beyond the Ohio River, for the double purpose of carrying the scourge of war into the heartland of the North and restoring the glitter to his somewhat tarnished reputation; but Bragg (unlike Lee, who assented, though with misgivings, to a somewhat similar proposal by Jeb Stuart that same week in Virginia, preliminary to his crossing of the Potomac) had withheld approval of this extension of the raid, not wanting the Kentuckian and his men to be too far away in case Rosecrans lurched into motion in their absence. As it turned out, however, when he received word from his outposts on June 24 that the Federals were indeed in motion, not only on the left and right but also against his center, Morgan was already beyond reach, and Bragg did not discover until some weeks later, along with news of the disastrous consequences, that the freewheeling cavalryman had simply disobeyed the restrictive portion of the orders he had received.
Just now, though, Bragg had troubles enough on his hands, without looking afield for others. Correctly identifying the movements on Bradyville and Guy’s Gap as feints, he left Crittenden and Granger to the attention of Forrest and Wheeler, and concentrated instead on opposing with his infantry the more immediate danger to his front. On the 25th he counterattacked at Liberty Gap, which had fallen to McCook the previous evening. Hardee failed to drive the bluecoats from the pass but he did succeed in holding them there, and Bragg, encouraged by this, sent orders for Polk to advance next day through Guy’s Gap, then swing east for a descent on the rear of the troops opposing Hardee. Polk, as usual, protested, and Bragg as usual insisted. He reversed himself that night, however, on learning that the column under Thomas was approaching Manchester, still preceded by Wilder’s rapid-firing horseback infantry and followed by Crittenden, who had abandoned his feint toward McMinnville and turned south at Bradyville. There was nothing for it now, as Bragg assessed the situation, but to call off the proposed attack on Liberty Gap and fall back on Tullahoma to protect his base and his present flank and rear. This he did with all possible speed, though the going was heavy; Polk left Shelbyville early on the 27th and did not reach Tullahoma, eighteen muddy miles away, until late next afternoon, soon after Hardee completed his march down the railroad in the rain. At any rate Bragg’s army now was concentrated, protected by works prepared in advance, and he was determined to give the Yankees battle there.
Once more Rosecrans was unco-operative. Having reached Manchester the day before, June 27, he spent a day replenishing supplies brought forward on the hard-surfaced pike, and then resumed his march, not toward Tullahoma, as Bragg expected, but southeastward as before, toward Hillsboro and Pelham, still threatening the railroad on which his adversary depended for subsistence. At a council of war held on the night of the 28th, when Polk expressed some uneasiness that the Federals would continue their previously successful tactics by circling the right flank, Bragg taunted him by asking: “Then you propose that we shall retreat?” The bishop did indeed. “I do,” he said firmly, “and that is my counsel.” Hardee was less positive; he thought perhaps protection of the rear could be left to the cavalry while the infantry fought in its present intrenched position, outflanked or not; Rosecrans might gain the Confederate rear only to find the Confederates in his own. Bragg adjourned the council without making any definite decision. He would await developments, he said.
Developments were not long in coming. Granger and McCook had occupied Shelbyville and Wartrace that same day, moving in behind the departed graybacks, and though Rosecrans had no intention of attacking Tullahoma from the north, the presence of these two divisions at the crossings of the Duck was a menace Bragg could not ignore. Meanwhile Thomas, with McCook’s other two divisions in support and Crittenden close behind, continued his march from Manchester to Hillsboro, a dozen miles due east of Bragg’s right flank, and sent Wilder’s hard-riding foot soldiers—already dubbed “The Lightning Brigade” as a result of their rapid seizure of Hoover’s Gap on the opening day of the campaign—ahead to Pelham for an independent crossing of Elk River and a strike at the railroad near Decherd or Cowan, twenty miles in rear of the rebel works at Tullahoma. High trestles over gorges along this mountainous stretch of the line presented inviting targets, since the destruction of even one of them would be about as effective, so far as the flow of supplies was concerned, as the destruction of them all. Wilder’s men rode fast and hard, anticipating further revenge for the Munfordville indignity. Reaching Decherd on June 28, they attacked a small detachment of rebel guards and drove them from a stockade: only to discover that a railroad might be vulnerable in some ways, yet still be highly defensible in others. No less than six gray regiments of infantry, responding to a telegraphic summons from the guards, arrived suddenly aboard cars from up the line. The blue raiders had barely time to get away on their horses
, avoiding capture by the superior force and contenting themselves with the wrecking of an alternate trestle near Winchester, on the branch line to Fayetteville. Next morning, after a fireless bivouac in the brush, they tried the main line again, this time below Cowan, but with similar results; the ultramobile Confederate infantry once more drove them off before they could inflict any serious damage. Wilder fell back toward Pelham, pausing near Sewanee to wreck another trestle on the branch line to Tracy City, then continued his withdrawal, hastened by the interception of information that Forrest was on his trail. Aided by a driving rain, which obliterated his tracks, he eluded his pursuers and rode back into Manchester at noon of the 30th. Though he had failed to carry out his primary assignment, which had been to interrupt traffic on the Nashville & Chattanooga by destroying one of its main-line trestles, he had at any rate demolished one on each of the two branch lines, east and west, and he reported proudly that he had done so without the loss of a single man on the three-day expedition deep in the enemy rear. Thankful for what he had done, rather than critical for what he had not done, both Thomas and Rosecrans praised him highly for his resourcefulness and daring.
