Joseph B. Chambers

He Wrestled Away the Enemy’s Battle Flag

Joseph B. Chambers was born on May 4, 1833, in Beaver County, Pennsylvania. During the American Civil War, he served in the United States Army as a Private in Company F, 100th Pennsylvania Infantry, a regiment widely known as the Roundheads.

Chambers entered military service during the later years of the war, when Union and Confederate forces were locked in the prolonged fighting around Petersburg, Virginia. By March 1865, the Confederate position had become increasingly desperate as Union armies tightened their pressure on the defenses protecting Richmond and Petersburg.

His defining act of courage came on March 25, 1865, during the fighting associated with the Battle of Fort Stedman.

That morning, Confederate forces launched a major attack against the Union lines in an attempt to break the tightening siege. Fort Stedman was briefly captured, but Union troops quickly organized a counterattack and drove the Confederate forces back.

During the fighting, Chambers moved forward beyond the main Union position.

Near a sunken road, he encountered Confederate soldiers and saw the colors of the 1st Virginia Infantry. Regimental flags were among the most important symbols on a Civil War battlefield. They served as rallying points for troops, helped units maintain direction amid smoke and confusion, and carried enormous symbolic value.

Capturing an enemy flag therefore required a soldier to expose himself to exceptional danger.

Chambers advanced toward the Confederate color bearer and seized the flagstaff.

A direct struggle followed.

He succeeded in taking possession of the colors of the 1st Virginia Infantry and brought the captured flag back toward the Union lines. His official Medal of Honor citation later summarized the action simply as the capture of the regiment’s colors.

The wording was brief, but the deed was not.

To reach an enemy flag meant moving directly into one of the most heavily contested points of a battlefield. Color guards were expected to defend their flags, and soldiers surrounding them understood that losing the colors was both a tactical and symbolic blow.

Chambers nevertheless secured the Confederate standard.

The action took place during one of the final major Confederate offensives around Petersburg. The failure at Fort Stedman further weakened General Robert E. Lee’s position, and within days Union forces began the operations that finally broke the Petersburg defenses and forced the evacuation of Richmond.

For Chambers, March 25, 1865, became the moment that defined his military service.

Recognition came several years after the war.

On July 27, 1871, Joseph B. Chambers was presented with the Medal of Honor for capturing the colors of the 1st Virginia Infantry during the fighting at Petersburg.

No additional clasp, star, or device accompanied his Medal of Honor.

His broader Union Army service also falls within the period later commemorated by the Army Civil War Campaign Medal. That decoration was established after the war to recognize qualifying United States Army service during the conflict. Chambers was still alive when the campaign medal was created, although no recipient-specific record has been established showing that he personally received or wore one.

The Medal of Honor, however, was unmistakably his.

It recognized a specific battlefield act performed under direct enemy threat.

Chambers had not captured a weapon abandoned after the fighting.

He had taken the colors of an active Confederate infantry regiment during combat.

The distinction mattered deeply in Civil War military culture. Regimental colors represented the identity and honor of the unit that carried them. Soldiers often rallied around the flag when formations became confused, and color bearers were frequent targets because the position of the flag revealed the location of a regiment.

To capture such a flag required getting close enough to its defenders to physically seize it.

That was what Chambers accomplished at Petersburg.

After the Civil War, he returned to civilian life and lived for more than four decades beyond the conflict. The battlefields on which he had served gradually became part of national memory, while the captured flag action preserved his own place in the history of the war.

Joseph B. Chambers died on October 8, 1908, in East Brook, Pennsylvania.

He was buried at Oak Park Cemetery in New Castle, Pennsylvania.

His Medal of Honor story is one of direct, personal combat.

On March 25, 1865, as the Petersburg campaign approached its final days, Private Joseph B. Chambers advanced into danger, seized the colors of the 1st Virginia Infantry, and carried the Confederate flag back to Union lines.

For capturing those colors under fire, he received the Medal of Honor and earned a lasting place among the soldiers recognized for extraordinary courage during the American Civil War.
