The companies of the 2nd Arkansas Infantry Battalion were originally intended as re-enforcements for the 1st Arkansas Infantry Regiment. After about three months' service in Virginia, the 1st Arkansas Regiment sent officers back to Arkansas on recruiting service. One of the men selected for this recruiting duty was William Naylor Bronaugh, a graduate of the University of Virginia had served as a professor at St. John's College at Little Rock. Bronaugh had entered service as a Lieutenant of Company D, "Clan McGregor", 1st Arkansas. Shortly thereafter, Lieutenant Bronaugh was appointed regimental adjutant. Lieutenant Bronaugh found three volunteer companies being organized at El Dorado, Hot Springs and Pine Bluff, and encouraged them to join the 1st Arkansas in Virginia. The three new companies headed for Virginia on September 3, 1861, where they were attached to the 1st Arkansas. The Confederate War Department refused to permit the 1st Arkansas to exceed its authorized regimental strength of ten companies. The Adjutant and Inspector-General's Office issued Special Orders, No. 194, dated October 29, 1861, which stated: "The following companies of Arkansas Volunteers are organized into a battalion to be designated the Second Infantry Battalion, Arkansas Volunteers, Major Bronaugh commanding." The companies were organized into the following lettered companies: A company of Maryland troops, called the "Maryland Zouaves," was attached to the 2nd Arkansas Battalion from February to June, 1862, but no muster rolls of the company for this period have been located. The Battalion Staff of the 2nd Arkansas Infantry Battalion were:
Battles
The newly organized 2nd Arkansas Battalion spent the first half of its existence assigned to picket duty in the Aquia District of Virginia—Major-General Theophilus Hunter Holmes, commanding—as part of Brigadier-General Samuel Gibbs French's mixed brigade, which included the 35th Georgia, 22nd North Carolina, 2nd Tennessee, 47th Virginia, Fredericksburg Artillery, Maryland Flying Artillery, Caroline Light Dragoons and Stafford Rangers. Spending the winter of 1861–62 on the shores of the Potomac took its toll on the battalion. The muster rolls for the period indicate that a large percentage of the troops were hospitalized, or were already dead. The following spring, however, would be worse. The 2nd Arkansas Battalion was transferred to Brigadier-General William Dorsey Pender's brigade, in Major-General Ambrose Powell Hill's "Light Division," in preparation for the campaign which would come to be known as the Seven Days' Battles. With the 2nd Arkansas Battalion in Pender's brigade were the 16th, 22nd and 34th North Carolina Regiments, and the 22nd Virginia Battalion. Heavily engaged throughout the campaign, the 2nd Arkansas Battalion failed to survive it. At Beaver Dam Creek, near the village of Mechanicsville, Virginia, on June 26, 1862, the little battalion led the assault on the Federal position, and was decimated. There is no official casualty list or after-action report from the 2nd Arkansas Battalion for the Battle of Mechanicsville—there were no commissioned or non-commissioned officers left standing to make out any reports. The battalion roster shows many names with the notation, "no further record." Since most of those so noted never returned to Arkansas, it is presumed that they were killed in the battle. An article published shortly after the battle of Mechanisville, The "Richmond Dispatch" newspaper provided an acknowledgment of the heroism and sacrifice of the 2nd Arkansas Battalion:
Flag
A flag belonging to the 2nd Arkansas Battalion was captured by Union sailors from the USS Anacostia on March 9, 1862. The flag was found by the sailors in trenches formerly occupied by the 2nd Arkansas Battalion and were identified by Oliver C. Cooper of the 1st Massachusetts Infantry as belonging to an Arkansas "company". The flag, which is a First National Flag Pattern, with eleven stars, measuring 35 and 1/2 inches by 61 and 1/2 inches is currently in the private collection of Paul Dolle of Rogers, Arkansas.
The remnant of the 2nd Arkansas Battalion was formally disbanded under Special Orders, No. 152, dated July 15, 1862. The 139 survivors were transferred to the 3rd Arkansas Infantry Regiment, but most of them were soon discharged for various wounds and illnesses. Many of those who were well enough to remain in service with the 3rd Arkansas would later fall at Gettysburg, Chickamauga and the Wilderness. A dozen or so would survive to be surrendered at Appomattox Court House.
