15th Alabama Infantry Regiment The 15th Alabama Infantry Regiment was a Confederate infantry unit raised in Alabama in 1861 that served in the Army of Northern Virginia and fought in major campaigns of the American Civil War. Organized from companies recruited in Montgomery, Mobile, Autauga, Coosa, Russell, and Perry counties, the regiment saw action in the Eastern Theater, including the Peninsula Campaign, Seven Days Battles, Antietam, Fredericksburg, Gettysburg, and the Overland Campaign under commanders who later figured in postwar politics and veterans' affairs.

Formation and Organization

The regiment was mustered in during May 1861 under state authority in Montgomery, Alabama and initially composed of ten companies drawn from counties such as Mobile County, Alabama, Autauga County, Alabama, Coosa County, Alabama, Russell County, Alabama, and Perry County, Alabama. Early organization placed the regiment in the brigade of Brigadier General Nicholas Longstreet's corps in the Army of Northern Virginia under generals including Pierre G.T. Beauregard and Joseph E. Johnston during the defense of Virginia. Officers commissioned included men who had served in the Alabama State Militia and who later interacted with figures from the Confederate Congress and state government.

Service History

After formation the 15th Alabama moved to the Virginia Peninsula for the Peninsula Campaign and participated in operations during the Siege of Yorktown (1862), afterward joining forces at the Seven Days Battles near Richmond, Virginia. The regiment subsequently fought at Second Battle of Bull Run as part of the Northern Virginia operations under commanders associated with the Army of Northern Virginia and then marched into Maryland for the Maryland Campaign culminating at Battle of Antietam. In 1862–1863 it served through the Battle of Fredericksburg and the Chancellorsville Campaign and was engaged at Gettysburg during the July 1863 Pennsylvania campaign. From 1864 the 15th Alabama endured the Overland Campaign and the Siege of Petersburg (1864–65) before participating in the final operations leading to the Appomattox Campaign.

Engagements and Battles

The regiment's combat record includes action at the Battle of Seven Pines, Gaines's Mill, Mechanicsville, Malvern Hill, and the Second Battle of Bull Run. It fought at South Mountain and Antietam on the Maryland Campaign, then at Fredericksburg and in the Gettysburg Campaign where it engaged on Pickett's Charge-associated operations and the fighting on the Second Day of Gettysburg. In 1864 the 15th Alabama took part in the Wilderness (1864) battles, Spotsylvania Court House, North Anna River, Cold Harbor, and the prolonged operations around Petersburg, Virginia. The unit's actions intersected with engagements near Five Forks, Hatcher's Run, and the Appomattox Court House climax of the Confederacy's Army of Northern Virginia.

Commanders and Notable Officers

Prominent commanders included Colonel William C. Oates, who later served as Governor of Alabama and represented the state in the United States House of Representatives; other field officers served under division commanders such as Major General Richard S. Ewell and Major General John B. Hood during various campaigns. Officers and non-commissioned leaders had wartime interactions with figures like Brigadier General Micah Jenkins, Lieutenant General James Longstreet, and Confederate staff officers who coordinated with the Department of Northern Virginia command structure.

Regimental Strength, Casualties, and Losses

At muster the regiment numbered roughly one thousand men but sustained steady attrition from combat, disease, and desertion over four years, mirroring unit trends across units in the Army of Northern Virginia. The 15th Alabama reported heavy casualties at key battles including Gaines's Mill, Antietam, Gettysburg, and the Wilderness, with many killed, wounded, captured, or missing. By the surrender at Appomattox Court House the regiment's effective strength was a small fraction of its original complement, consistent with consolidated remnants reported across Alabama regiments and Confederate infantry brigades.

Flags, Uniforms, and Equipment

Regimental colors included a battle flag patterned after motifs common to Alabama units and regimental standards carried during actions at Gettysburg and Antietam; surviving examples and contemporary descriptions appear in collections associated with the Confederate States Army militia artifact holdings. Uniforms typically reflected Confederate infantry issue with gray or butternut jackets, kepis, and forage caps, supplemented by locally procured clothing from textile centers such as Mobile, Alabama; accoutrements and small arms varied from imported Springfield Model 1861 muskets to captured Enfield (rifle) arms depending on supply conditions managed by Confederate ordnance officers.

Legacy and Commemoration

Postwar veterans of the 15th Alabama participated in reunions, veterans' organizations like the United Confederate Veterans, and memorialization efforts including monuments erected at battlefields such as Gettysburg National Military Park and markers in Alabama counties of origin. The regiment's history is cited in regimental histories, state military archives, and collections at institutions including the Alabama Department of Archives and History; its officers, notably William C. Oates, influenced postwar politics and commemoration debates connected to Civil War memory and battlefield preservation.
