The 1st Regiment Arkansas Volunteer Infantry (1863–1865) was an infantry regiment that served in the Union Army during the American Civil War. Although Arkansas joined the Confederate States of America in 1861, not all of its citizens supported secession. Arkansas formed some 48 infantry regiments to serve in the Confederate Army, but also formed another 11 regiments that served in the Union Army.^[1]
