In 1861 Kentucky governor
Beriah Magoffin appointed Buckner adjutant general, promoted him to
major general, and charged him with revising the state's militia laws. The state was torn between
Union and
Confederacy, with the legislature supporting the former and the governor the latter. This led the state to declare itself officially
neutral. Buckner assembled 61
companies to defend Kentucky's neutrality. On July 20, 1861, Buckner resigned from the state militia, declaring that he could no longer perform his duties due to the board's actions. After Confederate Maj. Gen.
Leonidas Polk occupied
Columbus, Kentucky, violating the state's neutrality, Buckner accepted a commission as a
brigadier general in the
Confederate States Army on September 14, 1861, and was followed by many of the men he formerly commanded in the state militia. When his Confederate commission was approved, Union officials in Louisville indicted him for treason and seized his property. (Concerned that a similar action might be taken against his wife's property in Chicago, he had previously deeded it to his brother-in-law.) He became a
division commander in the Army of Central Kentucky under Brig. Gen.
William J. Hardee and was stationed in
Bowling Green, Kentucky.
Fort Donelson After Union Brig. Gen. Ulysses S. Grant
captured Fort Henry on the
Tennessee River in February 1862, he turned his sights on nearby
Fort Donelson on the
Cumberland.
Western Theater commander
Gen. Albert Sidney Johnston sent Buckner to be one of four brigadier generals defending the fort. In overall command was the influential politician and military novice
John B. Floyd; Buckner's peers were
Gideon J. Pillow and
Bushrod Johnson. Buckner's division defended the right flank of the Confederate line of entrenchments that surrounded the fort and the small town of
Dover, Tennessee. On February 14, the Confederate generals decided they could not hold the fort and planned a breakout, hoping to join with Johnston's army, now in
Nashville. At dawn the following morning, Pillow launched a strong assault against the right flank of Grant's army, pushing it back . Buckner, not confident of his army's chances and not on good terms with Pillow, held back his supporting attack for over two hours, which gave Grant's men time to bring up reinforcements and reform their line. Buckner's delay did not prevent the Confederate attack from opening a corridor for an escape from the besieged fort. However, Floyd and Pillow combined to undo the day's work by ordering the troops back to their trench positions. Late that night the generals held a
council of war in which Floyd and Pillow expressed satisfaction with the events of the day, but Buckner convinced them that they had little realistic chance to hold the fort or escape from Grant's army, which was receiving steady reinforcements. General Floyd, concerned he would be tried for
treason if captured by the North, sought Buckner's assurance that he would be given time to escape with some of his
Virginia regiments before the army surrendered. Buckner agreed and Floyd offered to turn over command to his subordinate, Pillow. Pillow immediately declined and passed command to Buckner, who agreed to stay behind and surrender. Both Generals Floyd and Pillow left to leave General Buckner to surrender to the Union Forces. Pillow and Floyd were able to escape, as did cavalry commander Col.
Nathan Bedford Forrest. That morning, Buckner sent a messenger to the Union Army requesting an armistice and a meeting of commissioners to work out surrender terms. He may have been hoping Grant would offer generous terms, remembering the assistance he gave Grant when he was destitute, but Grant's reply was curt. Sending his aide
Colonel William Hillyer to deliver a dispatch in person, Grant's reply included his famous quotation, "No terms except unconditional and immediate surrender can be accepted. I propose to move immediately upon your works." To this, Buckner responded: The asperity of these notes was only superficial; Buckner greeted his old friend warmly when Grant arrived to accept the surrender. They joked about their time in Mexico and the incompetence of General Pillow. Grant offered to loan Buckner money to see him through his impending imprisonment, but Buckner declined. As mentioned above, Buckner had paid for then-Captain Grant's lodging in New York City after the Mexican War when Grant was destitute. As evidence of their mutual respect, Buckner later acted as a pall bearer and paid for Grant's funeral in 1885, as well as provided Grant's widow a financial monthly payment so she could live out her years. The surrender was a humiliation for Buckner personally, but also a strategic defeat for the Confederacy, which lost more than 12,000 men and much equipment, as well as control of the Cumberland River, which led to the evacuation of Nashville.
Invasion of Kentucky While Buckner was a Union
prisoner of war at
Fort Warren in
Boston, Kentucky
Senator Garrett Davis unsuccessfully sought to have him tried for treason. The following day he was promoted to
major general and ordered to
Chattanooga, Tennessee, to join Gen.
Braxton Bragg's
Army of Mississippi. Days after Buckner joined Bragg, both Bragg and Maj. Gen.
Edmund Kirby Smith began an invasion of Kentucky. As Bragg pushed north, his first encounter was in Buckner's home town of
Munfordville. The small town was important for Union forces to hold if they wanted to maintain communication with Louisville while pressing southward to Bowling Green and Nashville. A small force under the command of Col.
John T. Wilder guarded the town. Though vastly outnumbered, Wilder refused requests to surrender on September 12 and September 14. By September 17, however, Wilder recognized his difficult position and asked Bragg for proof of the superior numbers he claimed. In an unusual move, Wilder agreed to be blindfolded and brought to Buckner. When he arrived, he told Buckner that he (Wilder) was not a military man and had come to ask him what he should do. Flattered, Buckner showed Wilder the strength and position of the Confederate forces, which outnumbered Wilder's men almost 5-to-1. Seeing the hopeless situation he was in, Wilder informed Buckner that he wanted to surrender. Any other course, he later explained, would be "no less than willful murder". Bragg's men continued northward to
Bardstown where they rested and sought supplies and recruits. Meanwhile, Maj. Gen.
Don Carlos Buell's
Army of the Ohio, the main Union force in the state, was pressing toward Louisville. Bragg left his army and met Kirby Smith in Frankfort, where he was able to attend the
inauguration of Confederate Governor
Richard Hawes on October 4. Buckner, although protesting this distraction from the military mission, attended as well and gave stirring speeches to the local crowds about the Confederacy's commitment to the state of Kentucky. The inauguration ceremony was disrupted by the sound of cannon fire from an approaching Union division and the inaugural ball scheduled for that evening was canceled. : Actions in Buckner's sector (~ 3:45 p.m.) Based on intelligence acquired by a spy in Buell's army, Buckner advised Bragg that Buell was still ten miles from Louisville in the town of
Mackville. He urged Bragg to engage Buell there before he reached Louisville, but Bragg declined. Buckner then asked Leonidas Polk to request that Bragg concentrate his forces and attack the Union army at
Perryville, but again, Bragg refused. Finally, on October 8, 1862, Bragg's army—not yet concentrated with Kirby Smith's—engaged Maj. Gen.
Alexander McCook's corps of Buell's army and began the
Battle of Perryville. Buckner's division fought under General Hardee during this battle, achieving a significant breakthrough in the Confederate center, and reports from Hardee, Polk, and Bragg all praised Buckner's efforts. His gallantry was for naught, however, as Perryville ended in a tactical draw that was costly for both sides, causing Bragg to withdraw and abandon his invasion of Kentucky. Buckner joined many of his fellow generals in publicly denouncing Bragg's performance during the campaign.
Later Civil War service Following the Battle of Perryville, Buckner was reassigned to command the District of the Gulf, fortifying the defenses of
Mobile, Alabama. He arrived in
Knoxville on May 11, 1863, and assumed command the following day. Shortly thereafter, his department was converted into a district of the Department of Tennessee under Gen. Bragg and was designated the Third Corps of the Army of Tennessee. In late August, Union Maj. Gen.
Ambrose Burnside approached Buckner's position at Knoxville. Buckner called for reinforcements from Bragg at
Chattanooga, but Bragg was being threatened by forces under Maj. Gen.
William Rosecrans and could not spare any of his men. Bragg ordered Buckner to fall back to the
Hiwassee River. From there, Buckner's unit traveled to Bragg's supply base at
Ringgold, Georgia, then on to
Lafayette and
Chickamauga. Bragg was also forced from Chattanooga and joined Buckner at Chickamauga. On September 19 and 20, the Confederate forces attacked and emerged victorious at the
Battle of Chickamauga. Buckner's Corps fought on the Confederate left both days, the second under the "wing" command of Lt. Gen.
James Longstreet, participating in the great breakthrough of the Union line. After Chickamauga, Rosecrans and his
Army of the Cumberland retreated to fortified Chattanooga. Bragg held an ineffective siege against Chattanooga, but refused to take any further action as the Union forces there were reinforced by Ulysses S. Grant and reopened a
tenuous supply line. Many of Bragg's subordinates, including Buckner, advocated that Bragg be relieved of command. Thomas L. Connelly, historian of the Army of Tennessee, believes that Buckner was the author of the anti-Bragg letter sent by the generals to President
Jefferson Davis. Bragg retaliated by reducing Buckner to division command and abolishing the Department of East Tennessee. Buckner was given a medical leave of absence following Chickamauga, returning to Virginia, where he engaged in routine work while recovering his strength. His division was sent without him to support Longstreet in the
Knoxville Campaign, while the remainder of Bragg's army was defeated in the
Chattanooga campaign. Buckner served on the court martial of Maj. Gen.
Lafayette McLaws after that subordinate of Longstreet's was charged with poor performance at Knoxville. Buckner was briefly given command of Maj. Gen.
John Bell Hood's division in February 1864, and on March 8, he was given command of the reestablished Department of East Tennessee. The department was a shell of its former self—less than one-third its original size, badly equipped, and in no position to mount an offensive. Buckner was virtually useless to the Confederacy here, and on April 28, he was ordered to join Edmund Kirby Smith in the Trans-Mississippi Department of the Confederacy. Buckner had difficulty traveling to the West, and it was early summer before he arrived. He assumed command of the District of West Louisiana on August 4. Shortly after Buckner arrived at Smith's headquarters in
Shreveport,
Louisiana, Smith began requesting a promotion for him. The promotion to
lieutenant general came on September 20. Smith placed Buckner in charge of the critical but difficult task of selling the department's cotton through enemy lines. As news of Gen.
Robert E. Lee's surrender, on April 9, 1865, reached the department, soldiers deserted the Confederacy in droves. On April 19, Smith consolidated the District of Arkansas with the District of West Louisiana; the combined district was put under Buckner's command. On May 9, Smith made Buckner his chief of staff. Rumors began to swirl in both Union and Confederate camps that Smith and Buckner would not surrender, but would fall back to Mexico with soldiers who remained loyal to the Confederacy. Though Smith did cross the
Rio Grande, he learned on his arrival that Buckner had traveled to
New Orleans on May 26 and arranged terms of surrender. Smith had instead instructed Buckner to move all the troops to
Houston, Texas. At Fort Donelson, Tennessee, Buckner had become the first Confederate general of the war to surrender an army; at New Orleans, he became the last. The surrender became official when Smith endorsed it on June 2, (Only Brigadier General
Stand Watie held out longer; he surrendered the last Confederate land forces on June 23, 1865). ==Postbellum life==
