[295] Gen. John C. Breckinridge. July 3, 1862, it was ordered with Clayton's Second Alabama under Gen. James R. Chalmers against the Federals at Booneville, Miss., who were completely routed. Together with the Second Missouri cavalry, it was ordered, under Gen. Frank C. Armstrong, to Tennessee, where it met at Middleburg, Tenn., the Federals under Colonel Leggett, and defeated the enemy, killing and wounding large numbers of them. About the last of July the Second Arkansas, under Colonel Slemons, the Second Missouri, under Cot Robert McCulloch, and the Fourth Mississippi, under Wirt Adams, engaged the escort of Federal cavalry and artillery guarding a train of supplies at Britton's lane, Tenn., and after a stubborn conflict of three hours captured the train and 300 prisoners and two pieces of artillery. The Second Arkansas lost 70 men killed and wounded in this engagement. In the campaigns of Price and Pemberton in Mississippi, it was in continuous active service. Under General Chalmers, in 1863, it participated in the battles of Iuka, Coldwater, Colliersville and Salem. Under Gen. N. B. Forest, 1864, it participated in the masterly movements of that greatest of cavalry commanders, encircling armies, taking cities, capturing trains and burning bridges. It was then transferred to the Trans-Mississippi department. There it served with Cabell's, Gano's and Dockery's brigades, in the battles of Poison Spring, Marks' Mills and Jenkins' Ferry. It was with Price's army on the raid to the Missouri river, in the autumn of 1864, and engaged in the battles of Pilot Knob, Independence, West Point, and Marais des Cygnes, Kan. In the latter fight, Colonel Slemons' horse was killed and he fell with him, the saddle catching his leg under him so that he could not disengage himself. A number of officers of the brigade, 100 of his men and two pieces of artillery were captured with him. They were sent as prisoners of war first to Johnson's island, then to Rock Island, where they were detained until the end of hostilities. Colonel Slemons
