Patrick Henry Pentzer

The Captain Who Accepted a General's Surrender

Patrick Henry Pentzer was an American Civil War officer whose courage during the Battle of Fort Blakely, Alabama, on April 9, 1865, earned him the United States Medal of Honor. Serving as a captain in Company C of the 97th Illinois Volunteer Infantry, he was among the first Union soldiers to enter the Confederate defensive works during the final assault. There, he received the surrender of a Confederate general officer and took possession of the officer's headquarters flag. His actions were formally recognized with the Medal of Honor in 1879, establishing his place among the decorated soldiers of the Union Army.

Pentzer was born in 1839 in Marion County, Missouri. Although details of his childhood, family background, and education remain limited, he spent much of his life in Illinois. By the outbreak of the American Civil War in 1861, he was associated with Gillespie, Macoupin County, Illinois, where he entered military service in response to the national conflict.

In April 1861, shortly after the beginning of the Civil War, Pentzer enlisted as a private in Company H of the 9th Illinois Volunteer Infantry. This regiment was organized for three months of service during the Union's initial mobilization. Following his first period of military duty, Pentzer returned to service as the war expanded and additional volunteer regiments were raised.

On July 15, 1862, he enlisted for a three-year term as sergeant major of the newly organized 97th Illinois Volunteer Infantry. The regiment was mustered into federal service at Camp Butler, Illinois, on September 16, 1862. His appointment as sergeant major placed him among the regiment's senior noncommissioned officers during its formation and early operations.

The 97th Illinois Infantry initially served in Kentucky before moving south to participate in operations along the Mississippi River. During the closing months of 1862, the regiment joined Union forces preparing to capture Vicksburg, Mississippi, a major Confederate stronghold controlling an important section of the river.

The regiment participated in the Chickasaw Bayou operations in December 1862 and the successful attack on Arkansas Post in January 1863. These engagements formed part of the wider Union effort to weaken Confederate defenses along the Mississippi River and its tributaries.

Pentzer's military career advanced significantly on February 14, 1863, when he was promoted to captain. He subsequently assumed command of Company C of the 97th Illinois Infantry, with his captaincy recorded in the company's official roster from February 19, 1863.

As a captain, Pentzer served with a regiment that participated in the Vicksburg Campaign of 1863. The 97th Illinois fought in operations at Port Gibson, Champion Hill, and the Big Black River before taking part in the Siege of Vicksburg. The Confederate surrender of Vicksburg on July 4, 1863, marked a major Union victory and helped secure federal control of the Mississippi River.

Following the Vicksburg Campaign, the 97th Illinois was transferred to the Department of the Gulf. Its subsequent duties included service in Louisiana and operations along the Gulf Coast. By early 1865, the regiment was preparing to participate in the Union campaign against Mobile, Alabama, one of the Confederacy's remaining important coastal strongholds.

In March 1865, Union forces under Major General Edward R. S. Canby advanced against the Confederate defenses protecting Mobile. One of their principal objectives was Fort Blakely, a fortified position east of Mobile Bay. Confederate troops defended the fort with artillery, earthworks, and an extensive system of entrenchments.

The 97th Illinois Infantry joined the forces advancing against Fort Blakely. During the opening days of April, Union troops established siege positions and constructed approaches toward the Confederate defenses. The regiment participated in these operations as preparations continued for a final assault.

On April 9, 1865, Union commanders launched a major attack against Fort Blakely. The 97th Illinois was selected to lead part of the assault and advanced toward the Confederate fortifications under enemy fire. The fighting was intense as Union soldiers crossed exposed ground and entered the defensive works.

It was during this engagement that Captain Patrick Henry Pentzer performed the extraordinary action for which he would receive the Medal of Honor.

Advancing with the attacking troops, Pentzer was among the first Union soldiers to penetrate the Confederate entrenchments. During the fighting, he encountered a Confederate general officer whose position had been overtaken by the Union advance. Pentzer received the officer's surrender and took possession of his headquarters flag.

The capture of a general officer and his headquarters flag was a significant achievement during the assault. Military headquarters flags identified command positions, and their capture represented the surrender of an important Confederate command element. Pentzer's conduct demonstrated initiative and courage during the decisive stages of the engagement.

A nineteenth-century account of the 97th Illinois described Pentzer commanding the right of the regiment's skirmish line during the assault. The narrative recorded his advance into the Confederate works and the subsequent surrender of the general officer, whose headquarters flag he received.

The Battle of Fort Blakely ended in a Union victory. Confederate defenses were overwhelmed, thousands of Confederate soldiers were captured, and the fall of the fort contributed directly to the collapse of organized Confederate resistance around Mobile. The victory occurred on the same day that General Robert E. Lee surrendered the Army of Northern Virginia at Appomattox Court House.

Following the capture of Fort Blakely, the 97th Illinois participated in the occupation of Mobile and additional military operations in Alabama. The regiment subsequently moved to Texas, where it remained until it was mustered out of federal service on July 29, 1865.

Pentzer completed his wartime service holding the rank of captain, having advanced from private during his initial enlistment in 1861 to company commander during the final campaign of the war.

His distinguished conduct at Fort Blakely was formally recognized in 1879, when he received the Medal of Honor. The decoration honored his actions on April 9, 1865, particularly his early entry into the Confederate entrenchments and his acceptance of the surrender of a Confederate general officer and the officer's headquarters flag.

The award preserved the record of Pentzer's personal bravery during one of the last major Union assaults of the American Civil War. His recognition also became part of the military history of the 97th Illinois Infantry, whose wartime service had extended from the Mississippi River campaigns to the final operations against Mobile.

After leaving military service, Pentzer returned to civilian life. Although the details of his postwar occupation and personal activities are not extensively documented in the available historical records, he eventually settled in Missouri.

Patrick Henry Pentzer died on October 16, 1901, in Nevada, Missouri. He was buried in Springfield National Cemetery in Springfield, Missouri, where his grave is located in Section 24, Site 1696.

Pentzer's military legacy is defined by his progression through the Union Army's ranks and his bravery at Fort Blakely. From his early service as a private to his leadership as a captain in the 97th Illinois Infantry, his career reflected several years of military duty during the Civil War. His Medal of Honor remains a lasting recognition of the courage he demonstrated on April 9, 1865, when he entered the Confederate defenses and received the surrender of a general officer during the Union victory at Fort Blakely.
