1861 In August 1861, the regiment was transferred from the Memphis area to
New Madrid, Missouri, where it was part of the force of
Brigadier General Gideon Pillow. While at New Madrid, the regiment became known for its skill at
drill. In September, the unit was again transferred, this time to
Columbus, Kentucky. The regiment was issued weapons on September 23. In late December, the regiment was sent to
Bowling Green, Kentucky.
1862 Shiloh After the
Battle of Fort Donelson in early 1862, the regiment participated in the destruction of Confederate property during the abandonment of
Nashville, Tennessee. The 1st Missouri then joined
General Albert Sidney Johnston's
Army of Mississippi. The regiment was stationed at
Corinth, Mississippi, for some time. Bowen was promoted to brigadier general on March 14, and was replaced as regimental commander by Lieutenant Colonel Rich, who was officially promoted to colonel on April 1. In early April 1862, the 1st Missouri was part of Brigadier General
John C. Breckinridge's Reserve Corps of Johnston's army, and would be in Bowen's brigade along with the
9th Arkansas Infantry,
10th Arkansas Infantry,
2nd Confederate Infantry,
Hudson's Mississippi Battery,
Watson's Louisiana Battery, and a company of Kentucky
cavalry. On April 6, the first day of the
Battle of Shiloh, the 1st Missouri and the rest of Bowen's brigade attacked a
Union defensive position known as the Peach Orchard. After heavy fighting, the Confederate charge drove the Union troops from the Peach Orchard, although Johnston was mortally wounded during the fighting. On April 7, the 1st Missouri participated in the Confederate defense against Union
counterattacks, and played a significant role in preventing the capture of a portion of the
Washington Artillery. Eventually, the Confederate army retreated from the battlefield, and the 1st Missouri was part of the army's
rear guard on the march back to Corinth. At Shiloh, the regiment lost 48 men killed, 130 wounded, and 29 missing, for a total of 207; the regiment had begun the battle with around 850 men. Colonel Rich had been wounded on April 6; he died on August 9. Lieutenant Colonel Amos Camden Riley replaced Rich at the head of the regiment; Riley was officially promoted to colonel on August 2.
Corinth After the Confederates abandoned Corinth in the summer of 1862, the 1st Missouri was transferred to the
Vicksburg, Mississippi, area. The regiment, as well as the rest of Bowen's brigade, was expected to be part of the Confederate assault at the
Battle of Baton Rouge, but arrived too late for the fighting. By early October, the 1st Missouri was part of
Major General Earl van Dorn's
Army of West Tennessee. The regiment was part of Bowen's brigade of Major General
Mansfield Lovell's division. Bowen's brigade also contained the
6th Mississippi Infantry,
15th Mississippi Infantry,
22nd Mississippi Infantry, Caruther's Mississippi Battalion, and Watson's Louisiana Battery. On October 3, at the
Second Battle of Corinth, the 1st Missouri was part of the Confederate assault on the Union's outer defensive works. The 1st Missouri, along with the
33rd Mississippi Infantry, broke the line of the
15th Michigan Infantry, contributing to the collapse of the initial Union line. During the fighting, the 1st Missouri became separated from the rest of Bowen's brigade, and fought with the brigade of Brigadier General
John C. Moore for the rest of the day. The 1st Missouri
outflanked a Union position commanded by Brigadier General
John McArthur, helping Moore's brigade break the line. Moore's brigade then ran against Union reinforcements commanded by Colonel
Marcellus Crocker. The 1st Missouri outflanked the
15th Iowa Infantry, which, accompanied by Moore's primary assault on Crocker's line, led to the collapse of the Union position. However, Moore's brigade was not reinforced, and the Confederate assault died down. The next day, Bowen's brigade was only briefly engaged during Confederate attacks on the stronger interior Union position, as Lovell's division was mostly inactive on October 4. The regiment reported a total loss of seven men at Corinth, although historian James McGhee believes this total is incomplete. The 1st Missouri was part of the Confederate rear guard after Corinth, and participated in
skirmishing. On November 7, the 1st Missouri and the
4th Missouri Infantry were combined, as both regiments had suffered heavy losses. The new regiment was known as the
1st and 4th Missouri Infantry (Consolidated). After the consolidation, the Missourians joined the
First Missouri Brigade. Colonel Riley commanded the new regiment. Companies A, D, F, G, and K of the 1st and 4th (Consolidated) were from the 1st Missouri, while Companies B, C, E, H, and I were from the 4th. ==Legacy==
