1st Cavalry Regiment , Arkansas State Troops The 1st Cavalry Regiment , Arkansas State Troops ( 1861 ) was an Arkansas State infantry regiment during the American Civil War . The regiment was organized at Camp Walker , near Harmony Springs , Benton County , Arkansas . The regiment was officially designated as the Third Regiment ( Cavalry ) , Arkansas State Troops by the State Military Board , but was designated as the 1st Arkansas Cavalry by Brigadier General Nicholas Bartlett Pearce , Commander , 1st Division , Provisional Army of Arkansas . The regiment is referred to as the " Carroll ' s Regiment " in contemporary accounts . Organization . At the beginning of the war , the Arkansas Succession Convention created the Provisional Army of Arkansas . The Provisional Army was to consist of two divisions , the 1st Division in the western part of the state was to be commanded by Brigadier General Pearce , and the 2nd Division in the eastern half of the state , commanded by Major General James Yell . The intent of the Secession Convention was to transfer these state troop regiments into Confederate service as quickly as possible , to avoid the cost of paying for a large state army . The troops of the eastern division were transferred to the command of Brigadier General Hardee in July 1861 , but the troops of the western division under Brigadier General Pearce were not transferred to Confederate service before they became engaged in the Battle of Wilson ' s Creek . The unit ' s designation as the 1st Cavalry Regiment , Arkansas State Troops has its origins in the confusion caused by Brigadier General Nicholas B . Pearce ' s failure to comply with the numbering system for regiments adopted by the State Military Board . The State Military Board authorized a 1st and 3rd Arkansas Regiment of State Troops . The 1st Regiment was commanded by Colonel Patrick R . Cleburne and was organized a Mound City , in the 2nd or Eastern Division of the Army of Arkansas . The State Military Board had authorized a 3rd Regiment of State Troops as a cavalry regiment under Colonel DeRosey Carroll , and ordered it to join the 1st Division " ( actually a brigade ) of the Army of Arkansas commanded by General Nicholas B . Pearce in northwest Arkansas . The free - spirited General Pearce ignored the unit designations authorized by the State Military Board , and assigned his own designations , based on when each regiment showed up in camp to muster . The first units to arrive at the designate assembly point were naturally the mounted units which became Carroll ' s regiment , so the 3rd Regiment Arkansas State Troops was re - designated the 1st Regiment . The officially - sanctioned 2nd Regiment Arkansas State Troops , under Colonel John R . Gratiot , arrived at the assembly point third , and was immediately renamed the 3rd Regiment . Thus , all accounts of the State Troops in northwest Arkansas , including the battle of Wilson ' s Creek , refer to Gratiot ' s regiment as the 3rd Arkansas . Carroll ' s Regiment was composed of the following companies : Battles . Under the command of Colonel DeRosey Carroll , the 1st Cavalry Regiment , Arkansas State Troops was present engaged at the Battle of Wilson ' s Creek , Missouri on August 10 , 1861 . Unit suffered a total of five killed and 20 wounded in the battle . A statement of ammunition on hand , omitted from above report , shows that the several companies averaged less than eight rounds per man . Captain Charles Arthur Carroll ' s company , the " Pope Walker Guards , " of Crawford County , was assigned as Company A of Col . DeRosey Carroll ' s regiment of cavalry , however , this assignment should be considered as purely administrative . Historians believe that at least four of the regiments ' s companies never actually served with the regiment , but instead operated independently under the direct command of the division commander , Brigadier General Nicholas Bartlett Pearce , as scouts and escorts . Captain Carroll made his own report of the engagement to Brigadier General Pearce : Captain Carroll ' s company had been part of a force that General Pearce had sent to oppose and attack on the army ' s rear by Union Colonel Siegel . Pearce described the regiment and Captain Carroll ' s company ' s actions in his official report of the battle : Disbanded . Following the Battle of Wilson ' s Creek , the regiment , with the rest of the Arkansas troops , was marched back to Arkansas and given the opportunity to vote on the issue of being transferred into Confederate service . The regiment , along with the rest of the 1st Division voted to disband rather than be transferred to Confederate service . Many veterans of the regiments joined other Confederate units later in the war . DeRosey Carroll held no further commands during the war . He was reportedly murdered by bushwhackers in the front yard of his home at Charleston , Arkansas , in 1863 .
