Hampton Sidney Thomas

He Took Their Guns and Flags—Then Lost His Leg

Hampton Sidney Thomas was born on November 3, 1837, in Quakertown, Bucks County, Pennsylvania. He grew up in the greater Philadelphia region and received his early education in local schools. As a young man he learned the carpenter’s trade, and by 1860 he was working as a carpenter’s apprentice in Oxford, Pennsylvania. His civilian future appeared to be taking shape when the outbreak of the American Civil War changed the course of his life.

Following the Confederate attack on Fort Sumter and President Abraham Lincoln’s call for volunteers, Thomas responded quickly. On April 21, 1861, at the age of twenty-three, he enrolled for Union military service at West Chester, Pennsylvania. The following day he mustered into Company E of the 9th Pennsylvania Infantry as a Third Corporal.

This first period of service lasted only several months, but it introduced Thomas to military discipline at the beginning of the national emergency. When the regiment completed its three-month obligation and mustered out in July 1861, Thomas did not remain a civilian for long.

Within days, he volunteered again.

On July 31, 1861, Thomas enrolled for a new three-year term, and on August 1 he was commissioned Second Lieutenant in Company G of the 1st Pennsylvania Cavalry. He had moved rapidly from an enlisted noncommissioned position into the commissioned officer corps. Less than two months later, on September 27, he advanced to First Lieutenant.

The 1st Pennsylvania Cavalry became part of the Army of the Potomac and would participate in some of the most demanding mounted operations of the Civil War. Cavalry service demanded more than skill on horseback. Mounted troops performed reconnaissance, screened army movements, guarded roads and communications, conducted raids, delivered messages, and frequently fought both mounted and dismounted.

Thomas received his first significant combat experience during operations around Dranesville, Virginia. The regiment skirmished with Confederate forces in November 1861 and then supported Union operations during the Battle of Dranesville in December. These early encounters began a combat record that would eventually stretch across nearly the entire war.

In 1862, Thomas’s responsibilities expanded. He was assigned staff duties connected with the cavalry brigade and served under officers who were helping transform the Union cavalry from a scattered supporting arm into an increasingly effective battlefield force.

The cavalry operated across northern Virginia, scouting roads, protecting the Orange and Alexandria Railroad, watching Confederate movements, and supporting larger Union formations. Thomas gained experience not only in company-level leadership but also in staff work, reconnaissance, and the coordination of mounted forces.

By 1863, the cavalry war in Virginia had intensified dramatically. Thomas served as an inspector-general on brigade staff and participated in Major General George Stoneman’s cavalry operations before taking part in one of the largest mounted battles ever fought on the North American continent.

On June 9, 1863, Union and Confederate cavalry collided at Brandy Station, Virginia. The engagement marked an important moment in the development of Union cavalry. Federal horse soldiers who had once been considered inferior to their Confederate opponents fought aggressively across a sprawling battlefield.

Thomas played an active role in the fighting around Fleetwood Hill. During the engagement, Union artillery fell into Confederate hands, and Thomas led cavalrymen in an effort that helped recover the guns. The experience demonstrated the aggressive mounted leadership that would become increasingly characteristic of his wartime career.

Only days later, Thomas fought at Aldie and then participated in further cavalry clashes around Middleburg and Upperville as the Army of the Potomac attempted to determine the direction of General Robert E. Lee’s movement toward Pennsylvania.

The cavalry fighting continued northward, and Thomas eventually reached his home state during the Gettysburg Campaign.

On July 3, 1863, while massive infantry formations fought around Cemetery Ridge, Union and Confederate cavalry engaged east of Gettysburg. Thomas took part in the violent mounted combat there, where cavalrymen charged, fired carbines and pistols, and fought at close quarters with sabers.

The Union cavalry helped prevent Confederate mounted forces from achieving a breakthrough against the rear of the Army of the Potomac. Thomas survived the fighting and then joined the pursuit as Lee’s army withdrew from Pennsylvania.

His Civil War career, however, was repeatedly marked by wounds.

During the Bristoe Campaign in October 1863, Thomas was severely injured and required an extended period of hospitalization and recovery. The wound could easily have ended his military career, but after convalescence he returned to duty.

By the spring of 1864, Thomas was again riding with Union cavalry as Lieutenant General Ulysses S. Grant began the Overland Campaign against Lee’s Army of Northern Virginia.

On May 7, during fighting around Todd’s Tavern, Thomas again demonstrated aggressive leadership. When brigade commander Henry E. Davies and other Union officers were endangered during the confused cavalry fighting, Thomas participated in an effort that helped recover the situation.

He continued through the exhausting cavalry operations accompanying Grant’s campaign.

Thomas fought during the Union cavalry movement that culminated at Yellow Tavern on May 11, 1864, where Confederate cavalry commander J. E. B. Stuart received his mortal wound. Thomas then continued with the mounted forces during operations connected with Sheridan’s movement toward Richmond.

The following weeks brought more combat at Haw’s Shop, Cold Harbor, Trevilian Station, and Saint Mary’s Church. The pace of cavalry operations was relentless. Men and horses were subjected to long marches, limited rest, combat, and constant strain.

Thomas’s service again nearly ended at Reams Station on August 25, 1864.

During that fighting his horse was shot and killed, and Thomas was seriously injured in the fall. He required another period of medical recovery. Yet once again, after receiving treatment and leave, he returned to active command.

By January 4, 1865, his experience and leadership had brought him promotion to Major.

The war was now entering its final months.

In March 1865, Grant and the Army of the Potomac prepared for the campaign that would finally break the Confederate defenses around Petersburg. Union cavalry under Major General Philip Sheridan played a central role in the coming operations.

Thomas participated in the fighting at Dinwiddie Court House on March 31 and then at Five Forks on April 1. The Union victory at Five Forks threatened the final Confederate supply routes and helped force Lee to abandon Petersburg and Richmond.

Once the Confederate capital and Petersburg were evacuated, the campaign transformed into a desperate pursuit westward.

Lee’s Army of Northern Virginia attempted to reach supplies and possibly escape toward another Confederate army. Sheridan’s cavalry moved aggressively to get ahead of the retreating columns, strike their flanks, capture wagons and artillery, and block roads.

Major Hampton S. Thomas and the 1st Pennsylvania Veteran Cavalry became part of this relentless pursuit.

On April 5, 1865, near Amelia Springs, Virginia, Thomas entered the action that would define his military legacy.

Union cavalry struck Confederate forces and their vulnerable wagon columns as Lee’s army struggled westward. The Confederate trains contained the equipment and supplies necessary to keep the retreating army alive. Destroying or capturing those wagons could directly reduce Lee’s ability to continue the campaign.

Thomas led his cavalrymen aggressively into the fighting.

During the engagement, he displayed what his eventual Medal of Honor citation described as “conspicuous gallantry.”

His command captured a Confederate field battery.

They captured a number of enemy battle flags.

They also participated in the destruction of the Confederate wagon train.

Each of these accomplishments carried substantial military importance.

Capturing a field battery meant overcoming armed artillery crews and removing weapons that could otherwise continue firing on Union troops.

Capturing enemy colors was one of the most prized achievements in Civil War combat. Battle flags served as rallying points and symbols of a regiment’s identity. They were normally defended by dedicated color guards, making their capture especially dangerous.

The destruction of the wagon train struck directly at the Confederate army’s logistics. An army already retreating under pressure could not easily replace food, ammunition, equipment, horses, or transportation once those supplies were lost.

Thomas’s success therefore represented far more than a dramatic cavalry raid. His actions contributed to the accelerating collapse of Lee’s ability to continue organized resistance.

The fighting did not end with the initial capture.

Later during the action, Confederate troops counterattacked. Thomas and his cavalrymen were drawn into intense close combat as they attempted to hold their gains and protect the captured materials and colors.

Thomas fought through the crisis, but his horse was shot beneath him.

He was struck by enemy fire and suffered a devastating wound to his leg.

The injury was so severe that surgeons could not save the limb. Part of Thomas’s leg had to be amputated below the knee.

The action that had produced one of his greatest military victories had also permanently altered his life.

Only four days later, on April 9, 1865, General Robert E. Lee surrendered the Army of Northern Virginia at Appomattox Court House.

Thomas had therefore sacrificed part of his leg in one of the final major cavalry actions of the war in Virginia.

His courage at Amelia Springs received immediate military recognition through brevet advancement. Thomas had already been recognized with a brevet rank of Lieutenant Colonel for meritorious service, and his April 5 performance contributed to his brevet promotion to Colonel.

Brevet Colonel became his highest verified military rank.

The distinction between his ranks is important. Hampton Sidney Thomas was a Major when he performed the action that ultimately earned the Medal of Honor. His highest verified rank was Brevet Colonel.

Even after losing part of his leg, his formal Army service did not end immediately. Following recovery, he remained connected to the postwar cavalry organization and was eventually honorably mustered out in August 1865.

Thomas returned to Pennsylvania carrying the permanent physical consequences of nearly four years of military service.

His civilian life became remarkably active.

He entered business and worked as a coal dealer in the Philadelphia region. He also became involved in state and local public service, reflecting a pattern common among respected Civil War veterans who carried their wartime reputations into politics and government.

Thomas served as Sergeant-at-Arms of the Pennsylvania Senate and later became Register of Wills in Chester County. He subsequently held responsibilities associated with the Philadelphia Almshouse and worked in other public administrative positions.

Eventually, Thomas became a police magistrate in Philadelphia.

His postwar career therefore demonstrated that the loss of part of his leg did not prevent him from maintaining decades of professional and public activity.

Thomas also remained deeply connected to the memory of the cavalry with which he had served.

In 1889, he published a personal account titled Some Personal Reminiscences of Service in the Cavalry of the Army of the Potomac. The work preserved his memories of cavalry campaigning and provided a firsthand veteran perspective on the mounted operations in which he had participated.

By that time, more than two decades had passed since Appomattox. Former soldiers were increasingly recording their experiences, attending reunions, participating in veterans’ organizations, and helping transform the Civil War from living national trauma into documented history.

For Thomas, one matter of formal recognition still remained unresolved.

Although he had been praised for his conduct at Amelia Springs in 1865, the Medal of Honor was not formally presented to him until decades later.

On January 15, 1894, Hampton Sidney Thomas received the Medal of Honor.

Almost twenty-nine years separated his battlefield action from the official presentation.

The Medal of Honor had been authorized for the United States Army during the Civil War in 1862. At the time, the American military did not possess the extensive system of valor decorations developed during later generations.

For Civil War soldiers, the Medal of Honor consequently served as the principal federal recognition of exceptional battlefield gallantry.

Thomas’s citation recorded the scale of his achievement with unusual specificity: conspicuous gallantry in capturing a field battery and a number of battle flags and in destroying the enemy wagon train. It also recorded the terrible personal cost of the action—he lost a leg.

For the historical database, his verified decoration is Medal of Honor 1862–1895 Army — 1894.

The action itself took place on April 5, 1865.

The Medal of Honor was formally presented on January 15, 1894.

These dates must remain separate. The year 1894 records the formal recognition of courage demonstrated nearly three decades earlier during the final pursuit of Lee’s army.

Thomas received one Medal of Honor.

No additional star, clasp, bar, oak leaf cluster, or other device has been verified with the decoration.

His final verified decoration therefore remains Medal of Honor 1862–1895 Army — 1894 — no device or clasp.

Receiving the Medal of Honor late in life formally connected Thomas’s long civilian career to the cavalry charge that had permanently changed his body and secured his place in military history.

By the 1890s, he had become one of the surviving senior veterans of the Army of the Potomac’s cavalry. The young Third Corporal who had volunteered in April 1861 had become a veteran officer, public servant, memoirist, and Medal of Honor recipient.

Thomas continued performing his duties as a Philadelphia magistrate during his final years.

On May 21, 1899, Hampton Sidney Thomas died in Philadelphia at the age of sixty-one.

He was buried at Lawnview Cemetery in Pennsylvania.

His life had followed an extraordinary path: carpenter’s apprentice, three-month volunteer, cavalry lieutenant, brigade staff officer, wounded veteran, Major, Brevet Colonel, amputee, public official, author, and Medal of Honor recipient.

Yet the defining moment remained April 5, 1865.

As the Confederacy collapsed and Lee’s army struggled westward, Major Hampton Sidney Thomas led Union cavalry into the fighting near Amelia Springs. His men captured artillery, seized enemy battle flags, and helped destroy the Confederate wagon train.

Then the battle took part of his leg.

Nearly twenty-nine years later, the United States formally recognized that sacrifice with his single verified decoration: Medal of Honor 1862–1895 Army — 1894 — no device or clasp.

Hampton Sidney Thomas’s story remains one of the most dramatic cavalry narratives from the closing days of the American Civil War—a commander who took the enemy’s guns, captured their flags, smashed their vital wagon train, and paid for the victory with part of his own body.
