African-Americans served in the in the Civil War on both the Union and Confederate side. In the Union army, over 179,000 African American men served in over 160 units, as well as more serving in the Navy and in support positions. This number comprised of both northern free African Americans and runaway slaves from the South who enlisted to fight. In the Confederacy, African-Americans were still slaves and they served mostly in labor positions. By 1865, the South allowed slaves to enlist but very few actually did.
