African Americans in Confederate Ranks The 33rd Arkansas is one of the few regiments that included the names of African American servants and slaves on its muster rolls. While it was not uncommon for slaves and servants to accompany their masters to war, some even serving on the battlefield, it was uncommon for them to actually be carried on the unit's muster rolls. The following African Americans are included on the 33rd Arkansas Infantry Regiment's Muster rolls: Battles Prairie Grove Campaign The 33rd Arkansas was assigned to Colonel Robert G. Shaver's 2nd Brigade of Daniel M. Frost's 3rd Division of Major General Thomas C. Hindman's 1st Corps of the Army of the Trans-Mississippi for the Battle of Prairie Grove on December 7, 1862. The other regiments in the brigade were the 27th, 38th, and Adams' Arkansas Infantry Regiments. According to Colonel Robert G. Shaver's report on the Battle of Prairie Grove, the 38th was ordered to support Colonel Dandridge McRae's Brigade during the fight at Prairie Grove. After Prairie Grove the unit retreated to Van Buren, with the rest of Hindman's Army. On February 28, 1863, Brigadier General J. C.
