The original Mississippi Valley regiment was formed in the summer of 1861 from Mississippi and Arkansas troops who were sent to Kentucky under the command of Colonel
John Donelson Martin, assigned to
John S. Bowen's brigade. The regiment reported a total strength of 787 men in November 1861. After spending the winter at
Camp Beauregard, the regiment fought at the
Battle of Shiloh in April, 1862, taking 100 casualties. Col. Martin was promoted to brigadier general following the battle, and the regiment was disbanded on May 8 as the men's initial one-year terms of service were expiring. Caruthers' Sharpshooters independently took part in the
Second Battle of Corinth and the
Battle of Baton Rouge as part of General
John S. Bowen's brigade. In the Civil War, sharpshooter units often served as dispersed
skirmishers, positioned ahead of the main lines and tasked with eliminating enemy scouts, officers, and artillery crews, performing some tasks associated with modern
snipers. Following the success of Union sharpshooter units, the
Confederate Congress passed a resolution on April 21, 1862, ordering that sharpshooter battalions be organized from existing units. Sharpshooter battalions consisted of 3-6 companies attached to their parent brigade, with men selected for their marksmanship skill. The latest precision weapons and telescopic sights were rare in the Confederacy, but the
Sharps rifle, the short model
Enfield, and the imported British
Whitworth rifle were popular with Confederate sharpshooters due to their long-distance accuracy. During the
Atlanta campaign, the 1st Battalion saw combat in numerous battles as part of General
Winfield S. Featherston's brigade, fighting at
Resaca,
New Hope Church, and
Peachtree Creek. In General
John Bell Hood's subsequent
Tennessee Campaign, the battalion fought at
Battle of Franklin and
Nashville. Following these severe Confederate defeats, after a retreat back to Mississippi in December only 63 men were left in the battalion. During the
Carolinas campaign, the diminished battalion took part in some of the final battles of the war before surrendering in April, 1865. ==Commanders==
