Thomas served in the Mexican-American War and later chose to remain with the United States Army for the Civil War, despite his heritage as a Virginian. He won one of the first Union victories in the war, at Mill Springs in Kentucky, and served in important subordinate commands at Perryville and Stones River. His stout defense at the Battle of Chickamauga in 1863 saved the Union Army from being completely routed, earning him his most famous nickname, the "Rock of Chickamauga." He followed soon after with a dramatic breakthrough on Missionary Ridge in the Battle of Chattanooga. In the Franklin-Nashville Campaign of 1864, he achieved one of the most decisive victories of the war, destroying the army of Confederate General John Bell Hood, at the Battle of Nashville.
Thomas had a successful record in the Civil War, but he failed to achieve the historical acclaim of some of his contemporaries, such as Ulysses S. Grant and William T. Sherman. He developed a reputation as a slow, deliberate general who shunned self-promotion and who turned down advancements in position when he did not think they were justified. After the war, he did not write memoirs to advance his legacy. He also had an uncomfortable personal relationship with Grant, which served him poorly as Grant advanced in rank and eventually to the presidency.

Early life and military career
Thomas was born at Newsom's Depot, five miles (8 km) from North Carolina, in Southampton County, Virginia. His father, John Thomas, of Welsh descent, and his mother, Elizabeth Rochelle Thomas, a descendant of French Huguenot immigrants, had nine children. George was a middle child and the youngest of the three boys. The family led an upper-class plantation lifestyle. By 1829, they owned 685 acres (2.77 km2) and 24 slaves. John died in a farm accident when George was 13, leaving the family in financial difficulties. George Thomas, his sisters, and his widowed mother were forced to flee from their home and hide in the nearby woods during Nat Turner's 1831 slave rebellion. Benson Bobrick has suggested that while some repressive acts were enforced following the crushing of the revolt, Thomas took the lesson another way, seeing that slavery was so vile an institution that it had forced the slaves to act in violence. This was a major event in the formation of his views on slavery; that the idea of the contented slave in the care of a benevolent overlord was a sentimental myth. Christopher Einholf, in contrast wrote "For George Thomas, the view that slavery was needed as a way of controlling blacks was supported by his personal experience of Nat Turner's Rebellion. ... Thomas left no written record of his opinion on slavery, but the fact that he owned slaves during much of his life indicates that he was not opposed to it." A traditional story is that Thomas taught as many as 15 of his family's slaves to read, violating a Virginia law that prohibited this, and despite the wishes of his father.
Thomas was appointed to the United States Military Academy at West Point, New York, in 1836 by Congressman John Y. Mason, who warned Thomas that no nominee from his district had ever graduated successfully. Entering at age 20, Thomas was known to his fellow cadets as "Old Tom" and he became instant friends with his roommates, William T. Sherman and Stewart Van Vliet. He made steady academic progress, was appointed a cadet officer in his second year, and graduated 12th in a class of 42 in 1840. He was appointed a second lieutenant in Company D, 3rd U.S. Artillery.
Thomas's first assignment with his artillery regiment began in late 1840 at the primitive outpost of Fort Lauderdale, Florida, in the Seminole Wars, where his troops performed infantry duty. He led them in successful patrols and was appointed a brevet first lieutenant on November 6, 1841. From 1842 until 1845, he served in posts at New Orleans, Fort Moultrie in Charleston Harbor, and Fort McHenry in Baltimore. With the Mexican-American War looming, his regiment was ordered to Texas in June 1845.
In Mexico, Thomas led a gun crew with distinction at the battles of Fort Brown, Resaca de la Palma, Monterrey, and Buena Vista, receiving three brevet promotions. At Buena Vista, Gen. Zachary Taylor reported that "the services of the light artillery, always conspicuous, were more than unusually distinguished" during the battle. Brig. Gen. John E. Wool wrote about Thomas and another officer that "without our artillery we would not have maintained our position a single hour." Thomas's battery commander wrote that Thomas's "coolness and firmness contributed not a little to the success of the day. Lieutenant Thomas more than sustained the reputation he has long enjoyed in his regiment as an accurate and scientific artillerist." During the war, Thomas served closely with an artillery officer who would be a principal antagonist in the Civil War—Captain Braxton Bragg.
Thomas was reassigned to Florida in 1849–50. In 1851, he returned to West Point as a cavalry and artillery instructor, where he established a close professional and personal relationship with another Virginia officer, Lt. Col. Robert E. Lee, the Academy superintendent. His appointment there was based in part on a recommendation from Braxton Bragg. Concerned about the poor condition of the Academy's elderly horses, Thomas moderated the tendency of cadets to overwork them during cavalry drills and became known as "Slow Trot Thomas". Two of Thomas's students who received his recommendation for assignment to the cavalry, J.E.B. Stuart and Fitzhugh Lee, became prominent Confederate cavalry generals. Another Civil War connection was a cadet expelled for disciplinary reasons on Thomas's recommendation, John Schofield, who would excoriate Thomas in postbellum writings about his service as a corps commander under Thomas in the Franklin-Nashville Campaign. On November 17, 1852, Thomas married Frances Lucretia Kellogg, age 31, from Troy, New York. The couple remained at West Point until 1854. Thomas was promoted to captain on December 24, 1853.
In the spring of 1854, Thomas's artillery regiment was transferred to California and he led two companies to San Francisco via the Isthmus of Panama, and then on a grueling overland march to Fort Yuma. On May 12, 1855, Thomas was appointed a major of the 2nd U.S. Cavalry (later redesignated the 5th U.S. Cavalry) by Jefferson Davis, then Secretary of War. Once again, Braxton Bragg had provided a recommendation for Thomas's advancement. There was a suspicion as the Civil War drew closer that Davis had been assembling and training a combat unit of elite U.S. Army officers who harbored Southern sympathies, and Thomas's appointment to this regiment implied that his colleagues assumed he would support his native state of Virginia in a future conflict. Thomas resumed his close ties with the second-in-command of the regiment, Robert E. Lee, and the two officers traveled extensively together on detached service for court-martial duty. In October 1857, Major Thomas assumed acting command of the cavalry regiment, an assignment he would retain for 2½ years. On August 26, 1860, during a clash with a Comanche warrior, Thomas was wounded by an arrow passing through the flesh near his chin area and sticking into his chest at Clear Fork, Brazos River, Texas. Thomas pulled the arrow out and, after a surgeon dressed the wound, continued to lead the expedition. This was the only combat wound that Thomas suffered throughout his long military career.
In November 1860, Thomas requested a one-year leave of absence. His antebellum career had been distinguished and productive, and he was one of the rare officers with field experience in all three combat arms—infantry, cavalry, and artillery. On his way home to southern Virginia, he suffered a mishap in Lynchburg, Virginia, falling from a train platform and severely injuring his back. This accident led him to contemplate leaving military service and caused him pain for the rest of his life. Continuing to New York to visit with his wife's family, Thomas stopped in Washington, D.C., and conferred with general-in-chief Winfield Scott, advising Scott that Maj. Gen. David E. Twiggs, the commander of the Department of Texas, harbored secessionist sympathies and could not be trusted in his post.
Remaining with the Union
At the outbreak of the Civil War, 19 of the 36 officers in the 2nd U.S. Cavalry resigned, including three of Thomas's superiors—Albert Sidney Johnston, Robert E. Lee, and William J. Hardee. Many Southern-born officers were torn between loyalty to their states and loyalty to their country. Thomas struggled with the decision but opted to remain with the United States. His Northern-born wife probably helped influence his decision. In response, his family turned his picture against the wall, destroyed his letters, and never spoke to him again. (During the economic hard times in the South after the war, Thomas sent some money to his sisters, who angrily refused to accept it, declaring they had no brother.)
Nevertheless, Thomas stayed in the Union Army with some degree of suspicion surrounding him. On January 18, 1861, a few months before Fort Sumter, he had applied for a job as the commandant of cadets at the Virginia Military Institute. Any real tendency to the secessionist cause, however, could be refuted when he turned down Virginia Governor John Letcher's offer to become chief of ordnance for the Virginia Provisional Army. On June 18, his former student and fellow Virginian, Confederate Col. J.E.B. Stuart, wrote to his wife, "Old George H. Thomas is in command of the cavalry of the enemy. I would like to hang, hang him as a traitor to his native state." Nevertheless, as the Civil War carried on, he won the affection of Union soldiers serving under him as a "soldier's soldier", affectionately referring to Thomas as "Pap Thomas".
Thomas was promoted in rapid succession to be lieutenant colonel (on April 25, 1861, replacing Robert E. Lee) and colonel (May 3, replacing Albert Sidney Johnston) in the regular army, and brigadier general of volunteers (August 17). In the First Bull Run Campaign, he commanded a brigade under Maj. Gen. Robert Patterson in the Shenandoah Valley, but all of his subsequent assignments were in the Western Theater. Reporting to Maj. Gen. Robert Anderson in Kentucky, Thomas was assigned to training recruits and to command an independent force in the eastern half of the state. On January 18, 1862, he defeated Confederate Brig. Gens. George B. Crittenden and Felix Zollicoffer at Mill Springs, gaining the first important Union victory in the war, breaking Confederate strength in eastern Kentucky, and lifting Union morale.
Shiloh and Corinth
On December 2, 1861, Brig. Gen. Thomas was assigned to command the 1st Division of Maj. Gen. Don Carlos Buell's Army of the Ohio. He was present at the second day of the Battle of Shiloh (April 7, 1862), but arrived after the fighting had ceased. The victor at Shiloh, Maj. Gen. Ulysses S. Grant, came under severe criticism for the bloody battle and his superior, Maj. Gen. Henry W. Halleck, reorganized his Department of the Mississippi to ease Grant out of direct field command. The three armies in the department were divided and recombined into three "wings". Thomas, promoted to major general effective April 25, 1862, was given command of the Right Wing, consisting of four divisions from Grant's former Army of the Tennessee and one from the Army of the Ohio. Thomas successfully led this putative army in the siege of Corinth. On June 10, Grant returned to command of the original Army of the Tennessee.
Perryville, Stones River, Chickamauga, and Chattanooga
Thomas resumed service under Don Carlos Buell. During Confederate General Braxton Bragg's invasion of Kentucky in the fall of 1862, the Union high command became nervous about Buell's cautious tendencies and offered command of the Army of the Ohio to Thomas, who refused. Thomas served as Buell's second-in-command at the Battle of Perryville; although tactically inconclusive, the battle halted Bragg's invasion of Kentucky as he voluntarily withdrew to Tennessee. Again frustrated with Buell's ineffective pursuit of Bragg, the Union replaced him with Maj. Gen. William Rosecrans.
Fighting under Rosecrans, commanding the "Center" wing of the newly renamed Army of the Cumberland, Thomas gave an impressive performance at the Battle of Stones River, holding the center of the retreating Union line and once again preventing a victory by Bragg. He was in charge of the most important part of the maneuvering from Decherd to Chattanooga during the Tullahoma Campaign (June 22 – July 3, 1863) and the crossing of the Tennessee River. At the Battle of Chickamauga on September 19, 1863, now commanding the XIV Corps, he once again held a desperate position against Bragg's onslaught while the Union line on his right collapsed. Thomas rallied broken and scattered units together on Horseshoe Ridge to prevent a significant Union defeat from becoming a hopeless rout. Future president James Garfield, a field officer for the Army of the Cumberland, visited Thomas during the battle, carrying orders from Rosecrans to retreat; when Thomas said he would have to stay behind to ensure the Army's safety, Garfield told Rosecrans that Thomas was "standing like a rock." After the battle he became widely known by the nickname "The Rock of Chickamauga", representing his determination to hold a vital position against strong odds.
Thomas succeeded Rosecrans in command of the Army of the Cumberland shortly before the Battles for Chattanooga (November 23–25, 1863), a stunning Union victory that was highlighted by Thomas's troops storming the Confederate line on Missionary Ridge. As the Army of the Cumberland advanced further than ordered, General Grant, on Orchard Knob asked Thomas, "Who ordered the advance?" Thomas replied, "I don't know. I did not."
Atlanta and Franklin/Nashville
During Maj. Gen. William Tecumseh Sherman's advance through Georgia in the spring of 1864, the Army of the Cumberland numbered over 60,000 men, and Thomas's staff did the logistics and engineering for Sherman's entire army group, including developing a novel series of Cumberland pontoons. At the Battle of Peachtree Creek (July 20, 1864), Thomas's defense severely damaged Lt. Gen. John B. Hood's army in its first attempt to break the siege of Atlanta.
When Hood broke away from Atlanta in the autumn of 1864, menaced Sherman's long line of communications, and endeavored to force Sherman to follow him, Sherman abandoned his communications and embarked on the March to the Sea. Thomas stayed behind to fight Hood in the Franklin-Nashville Campaign. Thomas, with a smaller force, raced with Hood to reach Nashville, where he was to receive reinforcements.
At the Battle of Franklin on November 30, 1864, a large part of Thomas's force, under command of Maj. Gen. John M. Schofield, dealt Hood a strong defeat and held him in check long enough to cover the concentration of Union forces in Nashville. At Nashville, Thomas had to organize his forces, which had been drawn from all parts of the West and which included many young troops and even quartermaster employees. He declined to attack until his army was ready and the ice covering the ground had melted enough for his men to move. The North, including General Grant himself (now general-in-chief of all Union armies), grew impatient at the delay. Maj. Gen. John A. Logan was sent with an order to replace Thomas, and soon afterwards Grant started a journey west from City Point, Virginia to take command in person.
Thomas attacked on December 15, 1864, in the Battle of Nashville and effectively destroyed Hood's command in two days of fighting. Thomas sent his wife, Frances Lucretia Kellogg Thomas, the following telegram, the only communication surviving of the Thomases' correspondence: "We have whipped the enemy, taken many prisoners and considerable artillery."
Thomas was appointed a major general in the regular army, with date of rank of his Nashville victory, and received the Thanks of Congress:
... to Major-General George H. Thomas and the officers and soldiers under his command for their skill and dauntless courage, by which the rebel army under General Hood was signally defeated and driven from the state of Tennessee.
Thomas also received another nickname from his victory: "The Sledge of Nashville".
After the end of the Civil War, Thomas commanded the Department of the Cumberland in Kentucky and Tennessee, and at times also West Virginia and parts of Georgia, Mississippi and Alabama, through 1869. During the Reconstruction period, Thomas acted to protect freedmen from white abuses. He set up military commissions to enforce labor contracts since the local courts had either ceased to operate or were biased against blacks. Thomas also used troops to protect places threatened by violence from the Ku Klux Klan.
President Andrew Johnson offered Thomas the rank of lieutenant general—with the intent to eventually replace Grant, a Republican and future president, with Thomas as general in chief—but the ever-loyal Thomas asked the Senate to withdraw his name for that nomination because he did not want to be party to politics. In 1869 he requested assignment to command the Military Division of the Pacific with headquarters at the Presidio of San Francisco. He died there of a stroke while writing an answer to an article criticizing his military career by his wartime rival John Schofield. None of his blood relatives attended his funeral as they had never forgiven him for his loyalty to the Union and not Virginia. He was buried in Oakwood Cemetery, in Troy, New York. His gravestone was sculpted by Robert E. Launitz and comprises a white marble sarcophagus topped by a bald eagle.
His cadets at West Point gave him the nickname of "Slow Trot Thomas", and this sobriquet was used to diminish his reputation. He moved slowly because of an injured back, but he was mentally anything but slow, only methodical. He was known for accurate judgment and thorough knowledge of his profession and once he grasped a problem and the time was right for action, he would strike a vigorous, rapid blow.
The veterans' organization for the Army of the Cumberland, throughout its existence, fought to see that he was honored for all he had done.
Thomas was in chief command of only two battles in the Civil War, the Battle of Mill Springs at the beginning and the Battle of Nashville near the end. Both were victories. However, his contributions at the battles of Stones River, Chickamauga, Chattanooga, and Peachtree Creek were decisive. His main legacies lay in his development of modern battlefield doctrine and in his mastery of logistics.
Thomas has generally been held in high esteem by Civil War historians; Bruce Catton and Carl Sandburg wrote glowingly of him, and many consider Thomas one of the top three Union generals of the war, after Grant and William Tecumseh Sherman. But Thomas never entered the popular consciousness like those men. The general destroyed his private papers, saying he did not want "his life hawked in print for the eyes of the curious." Beginning in the 1870s, many Civil War generals published memoirs, justifying their decisions or refighting old battles, but Thomas, who died in 1870, did not publish his own memoirs. In addition, most of his campaigns were in the Western theater of the war, which received less attention both in the press of the day and in contemporary historical accounts.
Grant and Thomas also had a cool relationship, for reasons that are not entirely clear, but are well-attested by contemporaries. When a rain-soaked Grant arrived at Thomas's headquarters before the Chattanooga Campaign, Thomas, caught up in other activity, did not acknowledge the general for several minutes until an aide intervened. Thomas's perceived slowness at Nashville—although necessitated by the weather—drove Grant into a fit of impatience, and Grant nearly replaced Thomas. In his Personal Memoirs, Grant tended to minimize Thomas's contributions, particularly during the Franklin-Nashville Campaign, saying his movements were "always so deliberate and so slow, though effective in defence."
Grant also took painstaking care to praise Thomas's abilities, however. He openly and fully acknowledged in the event of Nashville that Thomas's success obviated all criticism. Sherman, who had been close to Thomas throughout the war, also repeated the accusation after the war that Thomas was "slow", and this damning with faint praise tended to affect perceptions of the Rock of Chickamauga well into the 20th century. Both Sherman and Grant attended Thomas's funeral, and were reported by third parties to have been visibly moved by his passing. Thomas's legendary bay horse, Billy, bore his friend Sherman's name.
In 1877, Sherman published an article praising Grant and Thomas, and contrasting them to Robert E. Lee. After noting that Thomas, unlike his fellow Virginian Lee, stood by the Union, Sherman wrote:
During the whole war his services were transcendent, winning the first substantial victory at Mill Springs in Kentucky, January 20th, 1862, participating in all the campaigns of the West in 1862-3-4, and finally, December 16th, 1864 annihilating the army of Hood, which in mid winter had advanced to Nashville to besiege him.
Sherman concluded that Grant and Thomas were "heroes" deserving "monuments like those of Nelson and Wellington in London, well worthy to stand side by side with the one which now graces our capitol city of 'George Washington.'"
A fort south of Newport, Kentucky was named in his honor, and the city of Fort Thomas now stands there and carries his name as well. A memorial honoring General Thomas can be found in the eponymous Thomas Circle in downtown Washington, D.C.
A distinctive engraved portrait of Thomas appeared on U.S. paper money in 1890 and 1891. The bills are called "treasury notes" or "coin notes" and are widely collected today because of their fine, detailed engraving. The $5 Thomas "fancyback" note of 1890, with an estimated 450-600 in existence relative to the 7.2 million printed, ranks as number 90 in the "100 Greatest American Currency Notes" compiled by Bowers and Sundman (2006).
A bust of Thomas is located in Grant's Tomb in Manhattan, New York.
A fine 3/4 length portrait of him, executed by US general Samuel Woodson Price (1828-1918) in 1869 and gifted by the heirs of General Price, hangs in the stairwell to Special Collections at Transylvania University, Lexington KY.

- Einolf, p. 19. Einolf's statement about owning slaves "during much of his life" is apparently derived from his family's ownership, his use of a family slave as a personal valet during "at least part of his military service", and the woman named Ellen whom his wife Francis bought in 1858 (p. 74).
- Cleaves, pp. 6-7; O'Connor, p. 60; Furgurson, p. 57, suggests that while this was illegal, it was not uncommon for slaves to be taught to read; biography of Thomas, by Kennedy Hickman. Einolf, p. 13, offers a contrary view: "It is unlikely, however, that Thomas taught his families slaves how to read .... While Thomas did eventually come to support education and freedom for blacks, he did not do so until much later in life, when the events of the Civil War had changed his views on race." He attributes (p. 12) the story to an interview conducted in 1890 by Oliver Otis Howard, who "wanted to explain Thomas's Unionism in terms of an antipathy toward slavery and so looked for early indications of sympathy toward African-Americans in Thomas's childhood."
