March 29th, 1862, while the 'Army of the Southwest' was lying at Cross Timbers, Missouri, M. La Rue Harrison, of the Thirty-sixth Illinois Volunteer Infantry, was given authority to recruit a company for the Sixth Missouri Cavalry, and proposed to enlist citizens of Arkansas, many of whom had escaped the Confederate conscription and fled into Missouri. The facility with which this was accomplished prompted the organization of the First Regiment Arkansas Cavalry Volunteers, which was effected August 7th, 1862.
Company G of this regiment was made up almost entirely of Carroll County men. Rowan E. M. Mack was captain; Joshua S. Dudley, first lieutenant. Hiram S. Shahan, of Carroll County, was quartermaster sergeant. Nearly all the men were enlisted in July and August, 1862.
Company K, Theodore Youngblood, captain, Dr. F. Youngblood, first lieutenant, was also largely made up of Carroll County men. The regiment constituted the advance guard of Gen. Schofield's command, the Army of the Frontier, during the campaign of 1862. It was stationed for a time at Elk Horn Tavern and Cassville, under Lieut. Col. A. W. Bishop. Col. Harrison assumed command December 5th, and under him the regiment participated in the battle of Prairie Grove.
January 8th, 1863, a detachment under Lieuts. Thompson and Vaughan participated in the defeat of Marmaduke at Springfield; and later in the same month another detachment was actively engaged in the vicinity of Van Buren. The regiment, with others, constituted the post of Fayetteville, and successfully withstood an attack from the Confederate Gen. Cabell April 18th, 1863. October 3rd, 1864, a similar attack from greatly superior numbers was also repelled.
Throughout the remainder of the war the regiment was engaged in suppressing the guerrilla bands that infested the northwestern part of the State. It was mustered out August 23rd, 1865.
The Second Arkansas Cavalry, in which were many Carroll County men, was originally organized as the First Arkansas Mounted Rangers, and was formed at Helena by Col. W. James Morgan, in 1862. In August, 1863, the regiment not having yet been filled, it was transferred to Col. John E. Phelps, who rendezvoused at Springfield and Cassville, "recruiting with such energy and success that, on the 18th of March, 1864, he was mustered in as colonel, twelve full companies having been formed." The regiment was afterward in active service in Mississippi and Tennessee. It was mustered out August 20th, 1865.
In various Missouri regiments and several regiments of Arkansas infantry Carroll County was also represented. It is not possible, however, to go into detail in this matter.
