James Dunlavy

He Captured a Confederate General While Wounded

James Dunlavy was born on February 4, 1844, in Decatur County, Indiana. The eldest of six sons, he grew up during a period of rapid national expansion and increasing political division. When the American Civil War entered its third year, Dunlavy joined the Union Army. In November 1863, at the age of nineteen, he became a Private in Company D of the 3rd Iowa Cavalry.

Dunlavy joined his regiment in Arkansas and spent much of his early military service in the western theater. The 3rd Iowa Cavalry operated across a wide region where mounted troops were essential for scouting, pursuit, raiding, and rapid battlefield movement. During his first year in uniform, Dunlavy experienced smaller engagements and operations, including encounters connected with Confederate cavalry forces, but nothing would compare with what awaited him in Kansas in October 1864.

That autumn, Confederate Major General Sterling Price led a major expedition through Missouri. His campaign initially aimed at important Union-held cities, but strong defenses and mounting Federal resistance forced him westward. After being defeated near Kansas City, Price’s army began retreating south with Union cavalry pursuing closely behind.

The retreat carried the Confederate column into Kansas. Price’s force was slowed by an enormous wagon train loaded with supplies gathered during the expedition. On October 25, 1864, Union cavalry caught a substantial portion of the retreating Confederate army near Mine Creek. What followed became one of the largest cavalry battles fought during the Civil War.

The 3rd Iowa Cavalry entered the engagement as part of the Union force pressing the Confederate retreat. Dunlavy rode with Company D as Federal cavalry prepared to charge across the battlefield. Confederate artillery was firing on the advancing Union troops, and the attack rapidly developed into a violent mounted clash.

During the charge, Dunlavy was struck and badly injured by a fragment of an exploding shell. His horse was also hit. Despite his wound, he continued forward.

In the confusion of the battle, Dunlavy approached a group of men wearing Federal uniforms and initially believed they were Union soldiers. Some Confederate troops had acquired Union clothing, however, and he soon realized that he had ridden toward the enemy.

Nearby, Dunlavy saw a Confederate officer attempting to rally his troops. He raised his carbine and fired at the officer but missed. The officer, apparently mistaking Dunlavy for one of his own men because of the confusion on the field, approached him. When the two came close enough for the situation to become clear, Dunlavy leveled his weapon and ordered the officer to surrender.

The Confederate officer complied.

Another Confederate soldier soon approached and, also misunderstanding the situation, asked to use the captured officer’s horse because his own mount had been shot. Dunlavy allowed him to take it and ordered his prisoner to proceed on foot. Only later did Dunlavy discover the true importance of the man he had captured.

His prisoner was Major General John S. Marmaduke, one of the senior Confederate commanders participating in Price’s expedition.

Still suffering from his wound, the nineteen-year-old Private brought Marmaduke into Union custody. The Confederate general was eventually turned over to Union officers, while Dunlavy was directed to receive medical attention.

The capture became one of the most remarkable incidents of the Battle of Mine Creek. Marmaduke was not the only senior Confederate officer taken during the engagement, but the circumstances of his surrender to a wounded Union Private gave Dunlavy’s action a distinctive place in the history of the battle.

Mine Creek ended as a decisive Union victory. Confederate forces suffered serious losses, large numbers of prisoners were captured, and Price’s already troubled expedition was further crippled. His army continued its retreat, and the campaign failed to achieve its strategic objectives.

Dunlavy received recognition for his extraordinary action. On April 4, 1865, he was awarded the Medal of Honor for his gallantry in capturing Major General John S. Marmaduke. The citation was remarkably concise, reflecting the clarity of the achievement itself: a Private in the Union cavalry had captured a Confederate major general during active combat.

The Medal of Honor had been created only a few years earlier during the Civil War, and Dunlavy became part of its earliest generation of recipients. His award recognized an action combining battlefield courage, quick judgment, and determination while already injured.

His Civil War service was also later recognized through the Army’s Civil War Campaign Medal, established in 1907 to commemorate qualifying military service during the conflict. By then, more than four decades had passed since Dunlavy had ridden into battle at Mine Creek.

Dunlavy formally mustered out of military service in August 1865. His life after the war followed a very different path from the cavalry campaigns of his youth. He pursued medical education and entered the medical profession, ultimately practicing medicine for approximately thirty-two years.

He married Letitia Catherine Von Achen, and the couple raised four children. His long career as a physician gave him decades of civilian service after the brief but extraordinary period that had made him a Medal of Honor recipient.

Dunlavy lived into the twentieth century, surviving many of the men who had fought alongside and against him during the Civil War. The young cavalryman who had captured a Confederate general eventually became an elderly veteran whose military service belonged to an increasingly distant era.

James Dunlavy died on March 6, 1923, in Enid, Oklahoma, at the age of seventy-nine. He was buried in the Odd Fellows Cemetery at Maramec, Oklahoma.

His legacy remains inseparable from the morning of October 25, 1864. Wounded during a cavalry charge, separated amid the confusion of battle, and confronted by enemy troops, Dunlavy did not withdraw. Instead, he turned an extraordinary encounter into the capture of one of the Confederacy’s senior generals.

The Medal of Honor preserved that moment in American military history. James Dunlavy entered the Battle of Mine Creek as a nineteen-year-old Private in the 3rd Iowa Cavalry and emerged from it as the soldier who had personally captured Major General John S. Marmaduke—an achievement that ensured his courage would be remembered long after the final cavalry charges of the Civil War had ended.
