1st Mississippi (African Descent) was an African American regiment raised in Mississippi during the American Civil War for service with the United States Colored Troops. Organized amid campaigns in the Vicksburg Campaign and the Department of the Tennessee, the regiment served in garrison, escort, and combat duties across the Western Theater under commanders associated with the Army of the Tennessee, 15th Corps, and other Union formations.

Formation and Recruitment

Recruitment began during the occupation of Vicksburg, Mississippi and along the Mississippi River following the Siege of Vicksburg, under policies influenced by the Emancipation Proclamation and the Militia Act of 1862. Enlistment drives drew freedmen and escaped enslaved persons from plantations near Jackson, Mississippi, Natchez, Mississippi, Meridian, Mississippi, and river ports used by the U.S. Navy's Mississippi Squadron. Recruitment was overseen by officers serving under directives from Edwin M. Stanton, Benjamin Butler, and local commanders reporting to Ulysses S. Grant and William T. Sherman. The regiment's formation paralleled other African American units such as the 54th Massachusetts Infantry Regiment, 1st Kansas Colored Infantry Regiment, and regiments of the United States Colored Troops system initiated by David Hunter and formalized by the Bureau of Colored Troops.

Organization and Composition

The unit was organized into companies labeled A through K in line with Union infantry structure dictated by the United States War Department. Composition included African American enlisted men with non-commissioned officers drawn from the ranks, while commissioned officers were typically white and appointed from officers who had served in units like the 3rd Illinois Cavalry Regiment, 6th Missouri Infantry Regiment, and other Department of the Gulf formations. The regiment's administrative framework connected it to the Adjutant General of the U.S. Army and payroll systems implemented after orders from Abraham Lincoln and the War Department (1861–1865). Soldiers originated from diverse backgrounds including formerly enslaved laborers affiliated with plantations owned by families such as the Pinckney family (South Carolina), affluent river merchants in Natchez Trace areas, and recruits displaced by the Confiscation Acts.

Service History and Engagements

The regiment performed garrison duty at Vicksburg, convoy and escort missions along the Mississippi Central Railroad, and operations supporting Sherman's strategic movements during the Meridian Campaign and later movements connected to the Atlanta Campaign. Elements took part in skirmishes near Raymond, Mississippi, Jackson, Mississippi, and actions along Yazoo City. The unit served in cooperation with the United States Colored Troops brigades and under brigade commanders who had previously led units at Shiloh, Chickasaw Bayou, and Perryville. The regiment's service overlapped with broader Union operations including expeditions coordinated with the Mississippi Marine Brigade, detachments from the XVII Corps, and patrols guarding supply lines tied to Sherman's March to the Sea logistics. Throughout 1864–1865, the regiment helped secure occupied territories during Reconstruction-era transitions enforced by the Freedmen's Bureau and the Reconstruction Acts' precursors.

Leadership and Notable Personnel

Command relationships connected the regiment to senior commanders such as Benjamin Grierson and theater commanders like Ulysses S. Grant and William T. Sherman. Company officers included lieutenants and captains commissioned from volunteer regiments including the 8th Illinois Cavalry Regiment and the 12th Iowa Infantry Regiment. Notable non-commissioned leaders emerged among sergeants and corporals who later interacted with Freedmen's Bureau agents and Reconstruction politicians associated with Hiram Revels and Blanche K. Bruce in Mississippi. Several veterans later testified before Congressional committees chaired by members of the Joint Committee on the Conduct of the War and engaged with organizations such as the Grand Army of the Republic.

Equipment, Uniforms, and Training

The regiment was equipped with standard issue Springfield and imported Enfield pattern muzzleloaders supplied through depots managed by the Quartermaster Department and shipped via the Mississippi River and rail networks tied to Illinois Central Railroad routes. Uniforms followed Union specifications with sack coats, forage caps, and haversacks procured through contracts overseen by the Assistant Secretary of War (1861–1865). Training drew on drill manuals used by volunteer units and instruction from officers experienced in engagements from Antietam to Pittsburg Landing (Shiloh). Discipline, marksmanship, and engineering tasks—such as fortification work modeled on earthworks at Vicksburg National Military Park—were emphasized, and medical care was provided by surgeons operating with the United States Sanitary Commission and personnel trained at medical facilities like Camp Letterman.

Disbandment and Legacy

Following the Confederacy's collapse after Appomattox Court House and the formal end of major hostilities, the regiment was mustered out and disbanded as part of postwar demobilization directed by the War Department (1865–1870). Veterans participated in Reconstruction-era civic life, interacted with the Freedmen's Bureau, and influenced politics in Mississippi during the Reconstruction legislatures. Their service contributed to the precedent for African American military service embodied later by units such as the 24th Infantry Regiment (United States) and informed debates leading to the Civil Rights Act of 1866 and the Fourteenth Amendment to the United States Constitution. Monuments and records at places such as Vicksburg National Military Park and repositories including the National Archives and Records Administration preserve their legacy.
