In July, 1862, the ranks of the Third Arkansas was augmented by the addition of nearly 140 soldiers from the 2nd Arkansas Infantry Battalion. The Second Arkansas Battalion had been organized in October, 1861, from three companies of volunteers from El Dorado, Hot Springs and Pine Bluff. In June, 1862, the 2nd Arkansas Battalion was decimated while leading an assault on the Federal position at Beaver Dam Creek, and its commander, Major William Naylor Bronaugh, mortally wounded. The War Department disbanded the battalion and transferred its survivors to the Third Arkansas.
