Simon Bolivar Buckner (/ˈsaɪmən ˈbɒlɪvər ˈbʌknər/ SY-mən BOL-i-vər BUK-nər; April 1, 1823 – January 8, 1914) was an American soldier, Confederate military officer, and politician. He fought in the United States Army in the Mexican–American War. He later fought in the Confederate States Army during the American Civil War. After the war, he served as the 30th governor of Kentucky.

After graduating from the United States Military Academy at West Point, Buckner became an instructor there. He took a hiatus from teaching to serve in the Mexican–American War, participating in many of its major battles. He resigned from the army in 1855 to manage his father-in-law's real estate in Chicago, Illinois. He returned to his native state of Kentucky in 1857 and was appointed adjutant general by Governor Beriah Magoffin in 1861. In this position, he tried to enforce Kentucky's neutrality policy in the early days of the Civil War. When the state's neutrality was breached, Buckner accepted a commission in the Confederate Army after declining a similar commission to the Union Army. In 1862, he accepted Ulysses S. Grant's demand for an "unconditional surrender" at the Battle of Fort Donelson. He was the first Confederate general to surrender an army in the war. He spent five months as a prisoner of war. After his release, Buckner participated in Braxton Bragg's failed invasion of Kentucky and near the end of the war became chief of staff to Edmund Kirby Smith in the Trans-Mississippi Department.

In the years following the war, Buckner became active in politics. He was elected governor of Kentucky in 1887, in his second campaign for that office. His term was plagued by violent feuds in the eastern part of the state, including the Hatfield–McCoy feud and the Rowan County War. His administration was rocked by scandal when state treasurer James "Honest Dick" Tate absconded with $250,000 from the state's treasury. As governor, Buckner became known for vetoing special interest legislation. In the 1888 legislative session alone, he issued more vetoes than the previous ten governors combined. In 1895, he made an unsuccessful bid for a seat in the U.S. Senate. The following year, he joined the National Democratic Party, or "Gold Democrats", who favored a gold standard policy over the Free Silver position of the mainline Democrats. He was the National Democratic Party's candidate for Vice President of the United States in the 1896 election, but polled just over one percent of the vote on a ticket with his running mate, ex-Union general John M. Palmer. He never again sought public office and died on January 8, 1914.

Simon B. Buckner (Sr.), was born at Glen Lily, his family's estate near Munfordville, Kentucky. He was the third child and second son of Aylett Hartswell and Elizabeth Ann (Morehead) Buckner. Named after the "Venezuelan soldier and statesman, Simón Bolívar who led the battles and independence from the Spanish Empire of Venezuela, Bolivia, Colombia, Ecuador, Peru, and Panama, then at the height of his power", Buckner did not begin school until age nine, when he enrolled at a private school in Munfordville. His closest friend in Munfordville was Thomas J. Wood, who would become a Union Army general opposing Buckner at the Battle of Perryville and the Battle of Chickamauga during the Civil War. Buckner's father was an iron worker, but found that Hart County did not have sufficient timber to fire his iron furnace. Consequently, in 1838, he moved the family to southern Muhlenberg County where he organized an iron-making corporation. Buckner attended school in Greenville, and later at Christian County Seminary in Hopkinsville.

On July 1, 1840, Buckner enrolled at the United States Military Academy. In 1844, he graduated eleventh in his class of 25 and was commissioned a brevet second lieutenant in the 2nd U.S. Infantry Regiment. He was assigned to garrison duty at Sackett's Harbor on Lake Ontario until August 28, 1845, when he returned to the Academy to serve as an assistant professor of geography, history, and ethics.

In May 1846, Buckner resigned his teaching position to fight in the Mexican–American War, enlisting with the 6th U.S. Infantry Regiment. His early duties included recruiting soldiers and bringing them to the Texas border. In November 1846, he was ordered to join his company in the field; he met them en route between Monclova and Parras. The company joined John E. Wool at Saltillo. In January 1847, Buckner was ordered to Vera Cruz with William J. Worth's division. While Maj. Gen. Winfield Scott besieged Vera Cruz, Buckner's unit engaged a few thousand Mexican cavalry at a nearby town called Amazoque.

On August 8, 1847, Buckner was appointed quartermaster of the 6th Infantry. Shortly thereafter, he participated in battles at San Antonio and Churubusco, being slightly wounded in the latter battle. He was appointed a brevet first lieutenant for gallantry at Churubusco and Contreras, but declined the honor in part because reports of his participation at Contreras were in error—he had been fighting in San Antonio at the time. Later, he was offered and accepted the same rank solely based on his conduct at Churubusco.

Buckner was again cited for gallant conduct at the Battle of Molino del Rey, and was appointed a brevet captain. He participated in the Battle of Chapultepec, the Battle of Belen Gate, and the storming of Mexico City. At the conclusion of the war, American soldiers served as an army of occupation, which left them time for leisure activities. In April 1848 Buckner was a part of the successful expedition of Popocatépetl, a volcano southeast of Mexico City. Buckner was accorded the honor of lowering the American flag over Mexico City for the last time during the occupation. Buckner joined the Aztec Club, a military society of officers who served during the Mexican War, in 1891.

After the war, Buckner accepted an invitation to return to West Point to teach infantry tactics. Just over a year later, he resigned the post in protest over the academy's compulsory chapel attendance policy. Following his resignation, he was assigned to a recruiting post at Fort Columbus.

Buckner married Mary Jane Kingsbury on May 2, 1850, at her aunt's home in Old Lyme, Connecticut. Just before the conclusion of the ceremony, a fire broke out at a nearby home and Buckner and others rushed away to help extinguish the blaze, in the process saving an aged colored servant in the home. Shortly after their wedding, he was assigned to Fort Snelling and later to Fort Atkinson on the Arkansas River in present-day Kansas. On December 31, 1851, he was promoted to first lieutenant, and on November 3, 1852, he was elevated to captain of the commissary department of the 6th U.S. Infantry in New York City. Previously, he had attained only a brevet to these ranks. Buckner gained such a reputation for fair dealings with the Indians, that the Oglala Lakota tribe called him Young Chief, and their leader, Yellow Bear, refused to treat with anyone but Buckner.

Before leaving the Army, Buckner helped an old friend from West Point and the Mexican–American War, Captain Ulysses S. Grant, by covering his expenses at a New York hotel until money arrived from Ohio to pay for his passage home. On March 26, 1855, Buckner resigned from the Army to work with his father-in-law, who had extensive real estate holdings in Chicago, Illinois. When his father-in-law died in 1856, Buckner inherited his property and moved to Chicago to manage it.

Still interested in military affairs, Buckner joined the Illinois State Militia of Cook County as a major. On April 3, 1857, he was appointed adjutant general of Illinois by Governor William Henry Bissell. He resigned the post in October of the same year. Following the Mountain Meadows massacre, a regiment of Illinois volunteers organized for potential service in a campaign against the Mormons. Buckner was offered command of the unit and a promotion to the rank of colonel. He accepted the position, but predicted that the unit would not see action. His prediction proved correct, as negotiations between the federal government and Mormon leaders eased tensions between the two.

In late 1857, Buckner and his family returned to his native state and settled in Louisville. Buckner's daughter, Lily, was born there on March 7, 1858. Later that year, a Louisville militia known as the Citizens' Guard was formed, and Buckner was made its captain. He served in this capacity until 1860, when the Guard was incorporated into the Kentucky State Guard's Second Regiment. He was appointed inspector general of Kentucky in 1860.

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.

The state board that controlled the militia considered it to be pro-secessionist and ordered it to store its arms. 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. That August he was twice offered a commission as a brigadier general in the Union Army—the first from general in chief Winfield Scott, and the second from Secretary of War Simon Cameron following the personal order of President Abraham Lincoln—but he declined. 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.

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 1 to 2 miles (2 to 3 km). 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:

SIR:—The distribution of the forces under my command, incident to an unexpected change of commanders, and the overwhelming force under your command, compel me, notwithstanding the brilliant success of the Confederate arms yesterday, to accept the ungenerous and unchivalrous terms which you propose.

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.

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. On August 15, 1862, after five months of writing poetry in solitary confinement, Buckner was exchanged for Union Brig. Gen. George A. McCall. 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.

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.

Following the Battle of Perryville, Buckner was reassigned to command the District of the Gulf, fortifying the defenses of Mobile, Alabama. He remained there until late April 1863, when he was ordered to take command of the Army of East Tennessee. 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).

Conditions set forth in Buckner's surrender were the following:

1. "All acts of hostility on the part of both armies are to cease from this date."
2. The officers and men are to be "paroled until duly exchanged."
3. All Confederate property was to be turned over to the Union.
4. All officers and men could return home.
5. "The surrender of property will not include the side arms or private horses or baggage of officers" and enlisted men.
6. "All 'self-disposed persons' who return to 'peaceful pursuits' are assured that may resume their usual avocations . . . "."

The terms of Buckner's parole in Shreveport, Louisiana, on June 9, 1865, prevented his return to Kentucky for three years. He remained in New Orleans, worked on the staff of the Daily Crescent newspaper, engaged in a business venture, and served on the board of directors of a fire insurance company, of which he became president in 1867. His wife and daughter joined him in the winter months of 1866 and 1867, but he sent them back to Kentucky in the summers because of the frequent outbreaks of cholera and yellow fever.

Buckner returned to Kentucky when he was eligible in 1868 and became editor of the Louisville Courier. Like most former Confederate officers, he petitioned the United States Congress for the restoration of his civil rights as stipulated by the 14th Amendment. He recovered most of his property through lawsuits and regained much of his wealth through shrewd business deals.

On January 5, 1874, after five years of suffering with tuberculosis, Buckner's wife died. Now a widower, Buckner continued to live in Louisville until 1877 when he and his daughter Lily returned to the family estate, Glen Lily, in Munfordville. His sister, a recent widow, also returned to the estate in 1877. For six years, these three inhabited and repaired the house and grounds which had been neglected during the war and its aftermath. On June 14, 1883, Lily Buckner married Morris B. Belknap of Louisville, and the couple made their residence in Louisville. On October 10 of the same year, Buckner's sister died, and he was left alone.

On June 10, 1885, Buckner married Delia Claiborne of Richmond, Virginia. Buckner was 62; Claiborne was 28. Their son, Simon Bolivar Buckner Jr., was born on July 18, 1886.

Buckner had a keen interest in politics and friends had been urging him to run for governor since 1867, even while terms of his surrender confined him to Louisiana. Unwilling to violate these terms, he instructed a friend to withdraw his name from consideration if it was presented. In 1868, he was a delegate to the Democratic National Convention that nominated Horatio Seymour for president. Though Buckner had favored George H. Pendleton, he loyally supported the party's nominee throughout the campaign.

In 1883, Buckner was a candidate for the Democratic gubernatorial nomination. Other prominent candidates included Congressman Thomas Laurens Jones, former congressman J. Proctor Knott, and Louisville mayor Charles Donald Jacob. Buckner consistently ran third in the first six ballots, but withdrew his name from consideration before the seventh ballot. The delegation from Owsley County switched their support to Knott, starting a wave of defections that resulted in Jones' withdrawal and Knott's unanimous nomination. Knott went on to win the general election and appointed Buckner to the board of trustees for the Kentucky Agricultural and Mechanical College (later the University of Kentucky) in 1884. At that year's state Democratic convention, he served on the committee on credentials.

Delegates to the 1887 state Democratic convention nominated Buckner unanimously for the office of governor. A week later, the Republicans chose William O. Bradley as their candidate. The Prohibition Party and the Union Labor Party also nominated candidates for governor. The official results of the election gave Buckner a plurality of 16,797 over Bradley.

Buckner proposed a number of progressive ideas, most of which were rejected by the legislature. Among his successful proposals were the creation of a state board of tax equalization, creation of a parole system for convicts, and codification of school laws. His failed proposals included creation of a department of justice, greater local support for education and better protection for forests.

Much of Buckner's time was spent trying to curb violence in the eastern part of the state. Shortly after his inauguration, the Rowan County War escalated to vigilantism, when residents of the county organized a posse and killed several of the leaders of the feud. Though this essentially ended the feud, the violence had been so bad that Buckner's adjutant general recommended that the Kentucky General Assembly dissolve Rowan County, though this suggestion was not acted upon. In 1888, a posse from Kentucky entered West Virginia and killed a leader of the Hatfield clan in the Hatfield-McCoy feud. This caused a political conflict between Buckner and Governor Emanuel Willis Wilson of West Virginia, who complained that the raid was illegal. The matter was adjudicated in federal court, and Buckner was cleared of any connection to the raid. Later in Buckner's term, feuds broke out in Harlan, Letcher, Perry, Knott, and Breathitt counties.

A major financial scandal erupted in 1888 when Buckner ordered a routine audit of the state's finances which had been neglected for years. The audit showed that the state's longtime treasurer, James "Honest Dick" Tate, had been mismanaging and embezzling the state's money since 1872. Faced with the prospect that his malfeasance would be discovered, Tate absconded with nearly $250,000 of state funds. He was never found. The General Assembly immediately began impeachment hearings against Tate, convicted him in absentia, and removed him from office. State auditor Fayette Hewitt was censured for neglecting the duty of his office, but was not implicated in Tate's theft or disappearance.

During the 1888 session, the General Assembly passed 1,571 bills, exceeding the total passed by any other session in the state's history. Only about 150 of these bills were of a general nature; the rest were special interest bills passed for the private gain of legislators and those in their constituencies. Buckner vetoed 60 of these special interest bills, more than had been vetoed by the previous ten governors combined. Only one of these vetoes was overridden by the legislature. Ignoring Buckner's clear intent to veto special interest bills, the 1890 legislature passed 300 more special interest bills than had its predecessor. Buckner vetoed 50 of these. His reputation for rejecting special interest bills led the Kelley Axe Factory, the largest axe factory in the country at the time, to present him with a ceremonial "Veto Hatchet".

When a tax cut passed over Buckner's veto in 1890 drained the state treasury, the governor loaned the state enough money to remain solvent until tax revenue came in. Later that year, he was chosen as a delegate to the state's constitutional convention. In this capacity, he unsuccessfully sought to extend the governor's appointment powers and levy taxes on churches, clubs, and schools that made a profit.

Buckner was a Compatriot of the Kentucky Society of the Sons of the American Revolution and was elected as a Vice President General in 1890.

After his term as governor, Buckner returned to Glen Lily. In 1895, he was one of four candidates nominated for a seat in the U.S. Senate — the others being the incumbent, J. C. S. Blackburn; outgoing governor John Y. Brown; and Representative James B. McCreary. The Democratic party split over the issue of bimetalism. Buckner advocated for a gold standard, but the majority of Kentuckians advocated "Free Silver". Seeing that he would not be able to win the seat in light of this opposition, he withdrew from the race in July 1895. In spite of his withdrawal, he still received 9 of the 134 votes cast in the General Assembly.

At the 1896 Democratic National Convention in Chicago, the Democrats nominated William Jennings Bryan for president and adopted a platform calling for the free coinage of silver. Gold standard Democrats opposed Bryan and the free silver platform. They formed a new party—the National Democratic Party, or Gold Democrats—which Buckner joined. At the new party's state convention in Louisville, Buckner's name was proposed as a candidate for vice president. He was given the nomination without opposition at the party's national convention in Indianapolis. Former Union general John Palmer was chosen as the party's nominee for president.

Palmer and Buckner both had developed reputations as independent executives while serving as governors of their respective states. Because they had served on opposite sides during the Civil War, their presence on the same ticket emphasized national unity. The ticket was endorsed by several major newspapers including the Chicago Chronicle, Louisville Courier-Journal, Detroit Free Press, Richmond Times, and New Orleans Picayune. Despite these advantages, the ticket was hurt by the candidates' ages, Palmer being 79 and Buckner 73. Further, some supporters feared that voting for the National Democrat ticket would be a wasted vote and might even throw the election to Bryan. Ultimately, Palmer and Buckner received just over one percent of the vote in the election.

Following this defeat, Buckner retired to Glen Lily but remained active in politics. Though he always claimed membership in the Democratic party, he opposed the machine politics of William Goebel, his party's gubernatorial nominee in 1899. In 1903, he supported his son-in-law, Morris Belknap, for governor against Goebel's lieutenant governor, J. C. W. Beckham. When the Democrats again nominated William Jennings Bryan in the 1908 presidential election, Buckner openly supported Bryan's opponent, Republican William Howard Taft.

At 80 years of age, Buckner memorized five of Shakespeare's plays because cataracts threatened to blind him, but an operation saved his sight. On a visit to the White House in 1904, Buckner asked President Theodore Roosevelt to appoint his only son as a cadet at West Point, and Roosevelt quickly agreed. His son Simon Bolivar Buckner Jr. would later serve in the U.S. Army and be killed at the Battle of Okinawa, making him the highest-ranking American to have been killed by enemy fire during World War II.

Following the deaths of Stephen D. Lee and Alexander P. Stewart in 1908, Buckner became the last surviving Confederate soldier with the rank of lieutenant general. The following year, he visited his son, who was stationed in Texas, and toured old Mexican–American War battlefields where he had served. In 1912, his health began to fail. He died on January 8, 1914, after a week-long bout with uremic poisoning. He was buried in Frankfort Cemetery in Frankfort, Kentucky.
