[63] Arkansas, and a quartermaster of the same regiment, went to the assistance of the other Hunt and brought the piece back. The Thirteenth lost 12 men killed, 45 wounded and 25 missing.

Subsequently, the Thirteenth Arkansas regiment was engaged in the bloody battle of Shiloh, April 6 and 7, 1862, Colonel Tappan joining it after the battle had opened and Lieutenant-Colonel Grayson had been killed; participated in the invasion of Kentucky by Kirby Smith, fighting gallantly under Cleburne in the battle of Richmond, August 30, 1862, and took a conspicuous part in the battles of Murfreesboro, Chickamauga, Missionary Ridge and Ringgold Gap. With the Arkansas troops under the lead of Cleburne, it stood by that gallant leader unflinchingly to the close of his career. Colonel Tappan, after the battle of Shiloh, was promoted to brigadier-gen-eral and was transferred to the Trans-Mississippi department, where he commanded a brigade composed of Shaler's regiment, Shaver's Seventh regiment, Col. R. S. Dawson's Sixteenth regiment, and the regiment of Col. S. H. Grinsted, in the defense of the Arkansas river and Little Rock, September, 1863, and was under Major-General Churchill at the battles of Pleasant Hill and Jenkins' Ferry, in 1864. Maj. J. A. McNeely, by succession, became colonel of the Thirteenth, and R. A. Duncan, major, frequently commanding the regiment with distinguished gallantry. The Thirteenth was consolidated with the Fifth Arkansas, under Col. John E. Murray, at the battle of Ringgold Gap, where their service was so distinguished as to receive the thanks of the Confederate Congress.
