First Sergeant, U.S. Army
Support & adopt this hero ↓Decatur Dorsey was a United States Army soldier and African American Civil War veteran whose courage during the Battle of the Crater earned him the Medal of Honor. He served in Company B of the 39th United States Colored Infantry, one of the African American regiments that formed part of the United States Colored Troops during the final years of the war. At the time of his Medal of Honor action, Dorsey held the rank of Sergeant, and his highest verified rank was First Sergeant. The 39th United States Colored Infantry was organized during a period when the Union Army was expanding the use of African American troops in combat. By 1864, United States Colored Troops were taking part in major operations in Virginia and elsewhere, often under extremely difficult conditions and with the added burden of racial discrimination both inside and outside the military. Dorsey’s regiment became part of the Union forces operating against Petersburg, Virginia. Petersburg was strategically vital because it served as a major transportation and supply center for Richmond, the Confederate capital. By the summer of 1864, Union forces had begun a prolonged campaign to break the Confederate defensive lines around the city. One of the most dramatic episodes of the Petersburg Campaign occurred on July 30, 1864, during the Battle of the Crater. Union engineers had dug a long tunnel beneath a section of the Confederate defenses and packed it with explosives. When the mine was detonated before dawn, a massive explosion tore open the Confederate line and created a huge crater in the earthworks. The explosion was intended to open a path for Union troops to break through the Confederate defenses. Instead, the attack quickly became confused and disorganized. Union soldiers entered the crater and surrounding trenches, where they became trapped under heavy Confederate fire. The 39th United States Colored Infantry was among the troops committed to the assault. During this desperate fighting, Sergeant Decatur Dorsey distinguished himself through exceptional courage. His Medal of Honor action took place on July 30, 1864, at Petersburg, Virginia. Dorsey advanced into the Confederate works under intense fire and planted his regiment’s colors on the Confederate fortifications. The act of carrying and planting a regimental flag in such circumstances involved extreme danger. During the Civil War, colors served as visible rallying points for troops. Soldiers used them to identify their unit, maintain alignment and rally during confusion. Because regimental flags were highly visible, the men who carried or protected them were often among the most exposed soldiers on the battlefield. Dorsey’s action therefore had both symbolic and practical importance. By carrying the colors forward and placing them on the Confederate works, he demonstrated that Union troops had reached the enemy position and provided a visible point around which his comrades could rally. The Battle of the Crater quickly became one of the most chaotic and tragic engagements of the Petersburg Campaign. Union troops found themselves crowded into and around the crater while Confederate forces regrouped and counterattacked. Fighting became close and violent, and the African American troops committed to the attack faced especially severe danger. Despite the confusion and heavy fire, Dorsey continued forward with the colors. His conduct stood out as an example of individual courage during a battle in which command and control had largely broken down. The Medal of Honor later recognized this specific act of bravery. Dorsey’s decoration was not based on general service or participation in the campaign. It recognized his actions at the Battle of the Crater on July 30, 1864. The Medal of Honor had been authorized for the United States Army during the Civil War in 1862. It became the nation’s highest military decoration and was awarded for extraordinary acts of courage and distinguished conduct. Dorsey’s Medal of Honor belongs to this original Civil War period of the Army decoration. For the project database, his award is correctly classified as Medal of Honor 1862–1895 Army. He received the Medal of Honor on November 8, 1865, more than a year after the action for which he was recognized. The 1865 date represents the formal award or presentation date. His heroic action remained the Battle of the Crater on July 30, 1864. No star, clasp, bar, oak leaf cluster or other separate device has been verified for Dorsey’s Medal of Honor. His decoration therefore appears without any additional device or clasp. The Medal of Honor became the defining decoration of Decatur Dorsey’s military career. His service also represents the broader contribution of African American soldiers during the Civil War. United States Colored Troops fought in some of the war’s most difficult campaigns and helped demonstrate the combat effectiveness of Black soldiers in the Union Army. Dorsey’s action at Petersburg was especially significant because it occurred during one of the most dangerous assaults undertaken by United States Colored Troops in Virginia. The Battle of the Crater exposed these soldiers to intense fire, confusion and heavy casualties. In that environment, Dorsey’s decision to carry his regiment’s colors forward and plant them on the enemy works required exceptional courage. A separate Army Civil War Campaign Medal is not included in his verified medal record. Although Dorsey unquestionably served during the American Civil War, the Army Civil War Campaign Medal was established long after the war. Decatur Dorsey died on July 11, 1891, before that later campaign medal existed. More importantly, the project requires recipient-specific evidence of entitlement rather than assuming that every Civil War veteran automatically received a later campaign medal. No recipient-specific issuance or entitlement record has been verified for Dorsey. For that reason, the Army Civil War Campaign Medal is not added to his final medal rack. His verified medal history therefore remains limited to the Medal of Honor. Dorsey survived the Civil War and lived for more than two decades after the conflict. The surviving historical record preserves far more information about his military service and Medal of Honor action than about many aspects of his later civilian life. Because of that, his postwar biography should not be expanded with unsupported details. What remains firmly established is his service in the United States Army, his membership in Company B of the 39th United States Colored Infantry, his rank as Sergeant during the Battle of the Crater and his later advancement to First Sergeant. His military legacy rests on the events of July 30, 1864. During one of the most chaotic assaults of the Petersburg Campaign, Dorsey carried his regiment’s colors forward under fire and planted them on the Confederate works. That act demonstrated courage, determination and devotion to his unit at a moment when the attack around him was collapsing into confusion. The United States formally recognized that conduct with the Medal of Honor. Decatur Dorsey died on July 11, 1891. Although much of his civilian life remains less thoroughly documented than his military record, his place in American military history is secure. He is remembered as a United States Army soldier, a member of the 39th United States Colored Infantry, a veteran of the American Civil War, a participant in the Battle of the Crater and a Medal of Honor recipient whose bravery under fire became the defining act of his military career.
