Turned out of Middle Tennessee: The Tullahoma Prelude
âI HAVE ARRIVED HERE and assumed command. My forces are on picket from this place to Chattanooga.â With this communiquĂ© from Kingston Tennessee on July 30, 1863, Brig. Gen. Nathan Bedford Forrest informed Maj. Gen. Simon Bolivar Buckner that his cavalry division had completed its retreat from Middle Tennessee and had assumed responsibility for patrolling the south bank of the Tennessee River between Kingston and the mouth of the Hiwassee River. It also marked an official end to one campaign and, after a short pause, the beginning of another.
The campaign just ended was Tullahoma. Five weeks earlier, Gen. Braxton Braggâs Confederate Army of Tennessee was camped 100 miles closer to Nashville at the southern edge of the Highland Rim, the geographical divide surrounding the Tennessee capital. Major General William S. Rosecransâ Union Army of the Cumberland opposed Bragg from its camps around Murfreesboro. Both armies had gone into winter quarters there after the savage late December 1862 and early January 1863 fighting at Stones River just outside Murfreesboro. Both sides had spent the following six months training and drilling, and resupplying. Although his superiors wanted him to act, Rosecrans had reasons for patienceâforemost among them his need to stockpile supplies. Moving southeast from Nashville against Bragg meant crossing land known as âthe Barrens.â Forage there was scarce. Rosecrans also needed to enhance his cavalry strength. And so the months slipped past.
This lull ended at the end of June 1863, when Rosecrans launched a flanking movement designed to cut off Braggâs Confederates from their rail supply line leading back to Chattanooga. Rosecrans set out with a battle in mind because he believed that any large-scale combat would be waged on his terms. If his flanking operation was successful, Rosecrans would have the initiative and Bragg would be out of position. In addition, the Union army significantly outnumbered its Confederate opponent.
While the Tullahoma operation did not turn out to be the Army of Tennesseeâs final standâthough only by a narrow marginâRosecransâ effort to deceive Bragg worked brilliantly. He feinted with his own cavalry and two infantry divisions against the Confederate left near Triune in order to convince Bragg that the threat would come from this direction, while the bulk of the Federal infantry (nearly 40,000 men) moved against the Rebel right. The feint fooled Maj. Gen. Joseph Wheeler, the leader of Braggâs cavalry. Wheelerâs command was already in the process of transferring from the Rebel armyâs right flank, riding west from Manchester and McMinnville to Shelbyville in response to an order from Bragg to concentrate for the coming campaign. Bragg intended that Wheeler, together with Brig. Gen. Nathan Bedford Forrestâs cavalry division, already in place on Braggâs left, either oppose the expected Union advance (the feint) or launch a raid against Rosecransâ long line of communications that stretched back into Kentucky. Thus, when the Federal feint got underway, Wheeler was riding west to join Forrest at Spring Hill, where he would assume command of the united force and await Braggâs next set of instructions.
Knowing that Wheelerâs departure would leave his own right flank denuded of mounted troops, Bragg intended to move Brig. Gen. John Hunt Morganâs cavalry division from Sparta to McMinnville. Wheeler left behind a small cavalry force to screen Braggâs right until Morgan arrived. Morgan, however, had other plans.
An inveterate risk-taker, for some time Morgan had envisioned a daring raid across the Ohio River onto Union soil. In Virginia early that June, Gen. Robert E. Lee began moving his Confederate Army of Northern Virginia north with the intention of clearing Federal troops from the Shenandoah Valley in preparation for a thrust into Maryland and beyond. Swept up in his own enthusiasm, Morgan told his subordinatesâbut somehow failed to inform Braggâthat perhaps they could meet Lee or remain in Illinois or Indiana for an extended period of time. The idea was entirely unfeasible, but Morgan could not be dissuaded from undertaking the raid.
Knowing he could not gain approval for such an impractical and dangerous operation, Morgan deliberately deceived his superiors by scaling back his ambitions. He asked Wheeler instead for permission to take a smaller force north and attack Louisville. On June 14, Wheeler pitched the idea to Bragg. This less ambitious plan appealed to both men because both wanted to strike at Rosecransâ lengthy supply lines stretching between Louisville and Nashville. Bragg approved a raiding force of one brigade, or about 1,500 men. Morgan wheedled Wheeler into upping that number to 2,000 troopers, all the while knowing he had no intention of moving with anything less than his entire command. On June 20, his duplicitous approval in hand, Morgan crossed the Cumberland River with three brigades of cavalry, about 2,500 men. His move carried the gray troopers into Kentuckyâand out of the rest of the campaign.
Rosecransâ movement began in the midst of all this shuffling of Rebel mounted troops. Wheeler reported to Bragg that the Triune movement was the primary Union advance. At the same time, a lack of cavalry on the Rebel right flank meant the Confederates failed to notice Rosecransâ main effort at all. Wheelerâs men were rding hard to finish their redeployment to Shelbyville when the first Union troops appeared near Manchester and seized the gaps through the Highland Rim. When Union infantry in strength appeared seemingly out of nowhere at Liberty and Hooverâs gaps, the terrible truth of what was unfolding struck Bragg. Rosecrans was turning his right flank, and the unexpected move threatened to envelop and destroy his badly outnumbered army. Bragg had no choice but to order a rapid retreat.
Federal and Confederate cavalry collided at Shelbyville on June 27 in a fight that rang an ominous note for future Confederate cavalry operations. Shelbyville, an important depot for Braggâs army, was being evacuated and wagon trains were rolling south across the Duck River as fast as they could. To protect them, Wheelerâs troopers deployed behind breastworks north of town, where they hoped to delay the enemy advance. Forrestâs division was still riding toward town when the first Union cavalry arrived at Shelbyville. The fight that followed, spearheaded by Col. Robert H. G. Mintyâs Federal brigade, was not one the Rebels would celebrate around campfires or in song. Mintyâs troopers overran Wheelerâs breastworks and thundered into the village, where a desperate street fight ensued. Wheeler had no choice but to hold on for as long as possible to make sure Forrest was not cut off and trapped north of the rain-swollen river. At one point Wheeler was forced across the river to the south bank, but when he heard from one of Forrestâs staff officers that the column was approaching Shelbyville, Wheeler called for volunteers and charged his way back across the bridge in a desperate effort to keep the route open for Forrestâs men. The two columns, however, never linked up. Instead, Forrestâs troopers found a crossing several miles outside of town and made their way successfully to the far side of the river. Forrest, however, neglected to send a messenger to inform Wheeler of his change in plans. Wheelerâs men were overwhelmed, several hundred were taken prisoner, and many barely escaped with their lives when they were forced to swim across the Duck. Shelbyville was a stunning triumph for the well-handled Union horsemen. Wheelerâs Rebel cavalry were routed and large amounts of supplies captured. The battle was similar in one important respect to the larger and bloodier June 9 cavalry battle at Brandy Station, Virginia, where Jeb Stuart was surprised and nearly routed by Alfred Pleasontonâs command. Both signified that the Union mounted arm was emerging as a powerful combat force. âAltogether it was the greatest cavalry disaster of the war,â concluded a Rebel officer caught up in the whole mess, âand I can attribute it to nothing but bad management. Gen. Wheeler was not himself at all.â
By the beginning of July, the Southern army was concentrated at Tullahoma, where some months before Bragg had prepared entrenchments in anticipation of just this kind of fight. What Bragg could never have planned for was the need to send significant numbers of men to Mississippi, where Maj. Gen. Ulysses S. Grantâs army had trapped the Confederates inside the city of Vicksburg. Once those troops were siphoned away, he was too shorthanded to stand and wage a pitched battle against the Army of the Cumberland. After a dayâs deliberation, Bragg abandoned Tullahoma and fled to Chattanooga where, with the Tennessee River acting as a barrier, Bragg hoped to recover his equilibrium. Rosecrans pursued the withdrawing Army of Tennessee, but heavy rains and the need to use secondary roads to bypass and outrun the retreating Confederate columns prevented him from catching Bragg. Despite Braggâs ultimate escape, Rosecransâ Tullahoma Campaign was a very importantâand largely overlookedâsuccess. The well-planned and executed operation cleared a large swath of Tennessee from Confederate control at minimal cost. The unexpected abandonment of so much acreage demoralized both those soldiers who served inside the Army of Tennessee and the Southern civilian population living in the abandoned region. The fact that the news came quickly on the heels of the twin Confederate defeats at Gettysburg and Vicksburg only added to the growing despair.
Arguably, Braggâs failure to divine Rosecransâ intentions immediately was an ironic stroke of good fortune. Had Wheeler figured out early what the enemy intended, Bragg may have stood and fought his heavily outnumbered and off-balance Army of Tennessee with a pair of rain-swollen rivers (the Duck and Elk) behind him. The failure of Rebel cavalry to provide Bragg with the intelligence he needed made his retreat and strategic defeat all but certain. Some reasons for the deficiency in Braggâs mounted arm are obvious, but others are more obscure and worth exploring.
Cavalry was a Civil War-era armyâs primary source for the gathering of intelligence, especially day-by-day tactical movements. Its many tasks included the screening of friendly forces, the shadowing of the enemy, and the transmission of timely and accurate reports. An effective screen kept friendly movements hidden, while the penetration of an opposing screen revealed enemy movements and plans. In this game of cut and thrust, the army with the fewest effective mounted troops usually operated at a disadvantage.
Keenly aware of the importance of cavalry to his Tullahoma plans, Rosecrans made strenuous efforts to increase both its effectiveness and the raw numbers of his mounted arm. During the six long months between the fighting at Stoneâs River and his advance on Tullahoma, Rosecrans bombarded his superiors in Washington with requests for more horses, more cavalry regiments, and better weapons. Despite pressing needs on every front, the War Department sent him several thousand horses. When those animals did not prove sufficient for his needs, Rosecrans authorized several infantry regiments to press local animals into service, and then converted them into mounted infantry. Colonel John T. Wilderâs brigade of five regiments was the principal beneficiary of these round-ups. By June, 2,500 mounted infantry were added to Rosecransâ horse cavalry strength. The firepower of the Federal cavalry was also significantly increased when the War Department sent Rosecrans several thousand Colt revolving rifles and breech loading carbines. Despising bureaucratic red tape, Wilder and his men arranged privately for the purchase of nearly 2,000 seven-shot, breech loading Spencer repeating rifles, which gave the brigade enough firepower to take on an enemy division. These significant improvements gave Rosecrans a sense of at least mounted parity with the Southern horsemen.
Bragg was at a considerable disadvantage in overall numbers, but he possessed a much larger contingent of mounted men than did Rosecrans. In May 1863, Bragg fielded some 17,000 horsemen in five divisionsâhalf again as many as his opponent. By the end of June, transfers to Mississippi and Morganâs raid into Ohio had diminished Braggâs cavalry arm by 5,000 men. Still, the 12,000 troopers remaining left him on par with Federal mounted strength. The Rebels could not match the Federals weapon for weapon, of course. Most of Braggâs troopers still carried muzzle-loading long-arms, at best an infantry weapon, and perhaps one-quarter of those were antiquated smoothbore muskets. Scouting and screening, however, involved less stand-up combat than a pitched battle, minimizing this deficiency.
For the approaching campaign around Chattanooga, however, the Rebel cavalry was reinforced by another 5,000 men from East Tennessee. This new force largely offset both the earlier detachments and the losses suffered during Tullahoma, returning Braggâs mounted strength to about 16,000 men. His troopers were led by cavalry generals of large reputation, including Joseph Wheeler and Nathan Bedford Forrest. How these leaders would do with the material at hand was yet to be determined.

Army of Tennessee: The Cavalry
By the mid-summer of 1863, Braxton Braggâs cavalry strength was imposingâat least on paper. Despite the loss of two divisions to other missions, on June 10 the Army of Tennesseeâs mounted arm numbered 13,868 officers and men present for duty. Another 500 troopers were acting as escorts for the various corps and army headquarters. Unfortunately, Confederate cavalry commanders maintained less than accurate records. This fact irritated Braggâs chief of staff W. W. Mackall, who rarely missed an opportunity to remind his boss. Even allowing for sloppy record keeping, Bragg had at least 12,000 troopers present in the ranks.
Unlike the Federals, Braggâs large mounted arm was not organized as one unified cohesive command. Prior to the summer detachments, the Southern army functioned with a pair of cavalry corps under Maj. Gens. Joseph Wheeler and Earl Van Dorn. Each officer was tasked with watching one of the armyâs flanks.
The first of these officers, Joe Wheeler, had been serving as General Braggâs chief of cavalry since July 1862. The native Georgian was a bantam of a man. In fact, he barely met the West Point height requirement when he was appointed to the academy in 1854. At just 26, he was also young. Although Wheeler was born on September 10, 1836, outside Augusta, he spent most of his youth far to the north in Connecticut and New York and secured his academy appointment from the latter state. After he graduated near the bottom of his 1859 classânineteenth out of twenty-twoâWheeler was commissioned a brevet 2nd lieutenant in the 1st United States Dragoons and assumed his first duty post at Carlisle Barracks in Pennsylvania. In 1860, Wheeler transferred to the Regiment of Mounted Rifles and headed west to the New Mexico Territory and Fort Craig, where he was promoted to 1st lieutenant that September. âFighting Joeâ was forever affixed to the young soldier during a skirmish with Indians.
Despite his years spent above the Mason Dixon Line, Wheeler considered himself a Southerner. After his home state left the Union, the Georgian submitted his resignation and accepted a commission in March 1861 as a lieutenant with a Georgia artillery unit. Fort Sumter fell the next month, and a week later Wheeler was dispatched to Pensacola, Florida, where his initial service under Braxton Bragg began. Wheeler began his Confederate career as colonel of the 19th Alabama Infantry that September, moving north to Huntsville, Alabama, and then south again to Mobile, where his regiment was assigned to Brig. Gen. Jones Withersâ command. Events ...
