Organized in Charleston, S.C., ca. 1798; the Irish Volunteers included many prominent members of the Hibernian Society who served as officers. Originally part of the 28th Regiment of the S.C. Militia, the Irish Volunteers Company was first on active service in the War of 1812 where they served on patrol and constructed defenses. The Irish Volunteers supported Nullification in 1832 and served in the second Seminole War (1835-1842) and the Mexican War (1846-1848). During the U.S. Civil War the Irish Volunteers became Company K, First Regiment, South Carolina Volunteers of the Confederate States of America Army under command of Captain W.H. Ryan.
In 1916 the unit was called upon to patrol the Mexican border which faced attacks by Pancho Villa. During World War I the unit became the 105th Ammunition Train. Following the war, members maintained the Company as a veterans' social organization.
