Henry A. Hammel

Henry A. Hammel was born on September 20, 1840, in Germany. The surviving authoritative military record preserves his name as Henry A. Hammel, but the full form of his middle initial has not been reliably established and should therefore not be expanded. He later came to the United States and entered military service from St. Louis, Missouri, during the American Civil War.

Hammel served in the United States Army with Battery A, 1st Missouri Light Artillery. Artillery units played a critical role during the Civil War, providing direct fire in support of infantry, defending important positions, and engaging enemy batteries. Their work required not only trained gun crews but also the constant movement and protection of cannon, ammunition, horses, equipment, and supply vehicles.

By April 1863, Hammel had risen to the rank of Sergeant. This was the rank he held during the action for which he later received the Medal of Honor. He subsequently advanced to First Sergeant, which remains the highest verified rank of his military career.

In early 1863, Union forces under Major General Ulysses S. Grant were engaged in the campaign against Vicksburg, Mississippi. The Confederate stronghold controlled an important section of the Mississippi River, and its capture was essential to the Union strategy of opening the river and dividing the Confederacy.

One of the major obstacles south of Vicksburg was Grand Gulf, Mississippi. Confederate forces had constructed powerful artillery positions overlooking the Mississippi River. These batteries threatened Union gunboats and transports and complicated Grant's effort to move his army across the river below Vicksburg.

During the operations of April 28 and 29, 1863, Battery A of the 1st Missouri Light Artillery was involved in the dangerous movement associated with the Union advance near Grand Gulf. The battery's guns and ammunition were being transported aboard the steamer Cheeseman.

Sergeant Henry A. Hammel, together with two comrades, Fitz W. Guerin and Joseph Pesch, voluntarily took position aboard the Cheeseman to remain responsible for the artillery pieces and ammunition belonging to the battery. Their decision placed them in an exceptionally dangerous situation.

During the operation, the steamer became unmanageable while exposed to heavy Confederate fire. A vessel unable to maneuver effectively beneath enemy batteries faced the danger of being repeatedly struck, disabled, burned, or destroyed. The presence of artillery ammunition aboard the vessel added another serious hazard.

Despite these conditions, Hammel and his comrades did not abandon the guns or ammunition. They remained aboard and continued guarding the battery's equipment while enemy fire was directed toward the vessel.

The importance of their decision went beyond personal bravery. Artillery pieces and ammunition represented essential combat resources for the advancing Union army. Losing them could reduce the firepower available to troops during the continuing Vicksburg Campaign. Hammel therefore accepted extraordinary personal danger while safeguarding equipment required for future military operations.

His action also demonstrated the particular responsibilities carried by an artillery noncommissioned officer. Hammel was not simply protecting his own safety or remaining at a fixed firing position. He assumed responsibility for the weapons and ammunition entrusted to the battery while the transport carrying them was in immediate danger.

The Grand Gulf operations formed part of one of the most important phases of Grant's Vicksburg Campaign. Union naval forces engaged the Confederate batteries while Grant sought a suitable location to move his army across the Mississippi. Although the defenses at Grand Gulf initially proved extremely difficult to overcome directly, Federal forces successfully crossed farther south and continued moving inland.

The campaign eventually resulted in the isolation and siege of Vicksburg. On July 4, 1863, the Confederate garrison surrendered to Grant, giving the Union effective control of the Mississippi River and producing one of the most strategically significant victories of the Civil War.

For Hammel, however, the events of April 28 and 29 remained the defining action of his military service. His courage aboard the Cheeseman was remembered long after the war, although formal national recognition did not come immediately.

More than thirty-two years after the Grand Gulf operation, Henry A. Hammel was awarded the Medal of Honor. The decoration was issued on March 10, 1896, recognizing his voluntary decision to remain aboard the endangered steamer with his comrades while responsible for the battery's guns and ammunition under heavy enemy fire.

His official Medal of Honor recognition specifically emphasized that Hammel and two fellow soldiers voluntarily took their position aboard the Cheeseman and remained responsible for the guns and ammunition for a considerable period while the vessel was unmanageable and subjected to severe enemy fire.

The Medal of Honor had originated during the Civil War. Congress authorized the Army Medal of Honor in 1862, creating a national decoration for extraordinary military conduct at a time when the United States did not yet possess the extensive hierarchy of valor awards that would develop in later generations.

Hammel's award presents an important historical ribbon-era detail. His Medal of Honor was issued on March 10, 1896. Although a new Army Medal of Honor ribbon was authorized later in 1896, Hammel's award predated that change. For the project database, his decoration therefore belongs to the Medal of Honor 1862–1895 Army historical representation, with 1896 retained as the actual year of issue.

This does not mean that his heroic action occurred in 1896. His Medal of Honor action always remains April 28–29, 1863, at Grand Gulf, Mississippi. The 1896 date represents the later formal presentation of the decoration, while the database version reflects the medal and ribbon system applicable at the time his award was issued.

No clasp, star, bar, oak leaf cluster, or other device has been verified for Hammel's Medal of Honor. His verified award therefore remains one plain Medal of Honor.

The Medal of Honor is also the only individual military decoration currently supported strongly enough for inclusion in Hammel's final verified medal record. His service during the American Civil War does not by itself establish recipient-specific entitlement to the later Army Civil War Campaign Medal.

In Hammel's case, the chronology provides an additional reason that the Army Civil War Campaign Medal should not be included. He died in 1902, several years before that later medal was established. Consequently, it does not belong in his verified ribbon rack.

Hammel's wartime record also shows advancement beyond the rank he held during his Medal of Honor action. He was a Sergeant at Grand Gulf and later reached First Sergeant. First Sergeant was the senior enlisted position within a company or battery organization and carried substantial responsibility for discipline, administration, personnel, and the effective functioning of the unit.

His advancement indicates that his military service was broader than the single famous incident aboard the Cheeseman. Although surviving Medal of Honor records provide the clearest documentation of the Grand Gulf action, his eventual promotion to First Sergeant reflects continued responsibility within Battery A.

After the Civil War, Hammel returned to civilian life. Surviving authoritative records preserve considerably more information about his military service than about the details of his postwar occupation and family life. Those uncertain aspects of his biography should therefore not be expanded without reliable documentary evidence.

What is firmly established is his continuing association with St. Louis, Missouri, the city from which he had entered military service. More than three decades after the war, it was during his lifetime that the United States finally recognized his Grand Gulf action with the Medal of Honor.

The presentation in 1896 transformed an act performed by a young artillery sergeant in 1863 into permanent national recognition. By then Hammel was in his mid-fifties and the Civil War had been over for more than thirty years.

Henry A. Hammel died on November 29, 1902, at the age of sixty-two. He was buried at Bellefontaine Cemetery in St. Louis, Missouri, where his grave preserves the memory of his service and Medal of Honor status.

His military legacy centers on a moment when remaining in place was far more dangerous than leaving. On April 28 and 29, 1863, while the steamer Cheeseman was unmanageable and exposed to heavy Confederate fire near Grand Gulf, Sergeant Henry A. Hammel voluntarily remained aboard with two comrades and accepted responsibility for the guns and ammunition of Battery A, 1st Missouri Light Artillery.

That act combined courage with professional responsibility. Hammel remained with equipment essential to his battery despite the danger posed by enemy artillery and the vulnerable condition of the vessel carrying it.

For that conduct, the United States presented Henry A. Hammel with the Medal of Honor on March 10, 1896. He later attained the rank of First Sergeant, the highest verified rank of his Army service. With no additional decoration supported by sufficient recipient-specific evidence, Medal of Honor 1862–1895 Army — 1896 remains his single verified medal and the defining official recognition of his service during the American Civil War.
