 Beginning with the fall of Little Rock to Union forces in 1863, Arkansans supporting the Union formed four infantry regiments, four cavalry regiments, and an artillery battery to serve in the United States Army.Additionally, six infantry regiments and one artillery battery of African Descent were attributed to the state.Later these units that were originally designated as the "1st-6th Arkansas Volunteers of African Descent" were re-designated as the 46th, 54th, 56th, 57th, 112th and 113th United States Colored Troops.
