Western Theater of the American Civil War in the context of "Braxton Bragg"

Mississippi was the second southern state to declare its secession from the United States, doing so on January 9, 1861. It joined with six other southern states to form the Confederacy on February 4, 1861. Mississippi's location along the lengthy Mississippi River made it strategically important to both the Union and the Confederacy; dozens of battles were fought in the state as armies repeatedly clashed near key towns and transportation nodes.

Mississippian troops fought in every major theater of the American Civil War, although most were concentrated in the Western Theater. Confederate president Jefferson Davis was a Mississippi politician and operated a large cotton plantation there. Prominent Mississippian generals during the war included William Barksdale, Carnot Posey, Wirt Adams, Earl Van Dorn, Robert Lowry, and Benjamin G. Humphreys.

During the American Civil War, Arkansas was a Confederate state, though it had initially voted to remain in the Union. Following the capture of Fort Sumter in April 1861, Abraham Lincoln called for troops from every Union state to put down the rebellion, and Arkansas along with several other southern states seceded. For the rest of the civil war, Arkansas played a major role in controlling the Mississippi River, a major waterway.

Arkansas raised 48 infantry regiments, 20 artillery batteries, and over 20 cavalry regiments for the Confederacy, mostly serving in the Western Theater, though the Third Arkansas served with distinction in the Army of Northern Virginia. Major-General Patrick Cleburne was the state's most notable military leader. The state also supplied four infantry regiments, four cavalry regiments and one artillery battery of white troops for the Union and six infantry regiments and one artillery battery of "U.S. Colored Troops."

The Battle of Chickamauga, fought on September 18–20, 1863, between the United States Army and Confederate forces in the American Civil War, marked the end of a U.S. Army offensive, the Chickamauga Campaign, in southeastern Tennessee and northwestern Georgia. It was the first major battle of the war fought in Georgia and the most significant Union defeat in the Western Theater, and it involved the second-highest number of casualties after the Battle of Gettysburg.

The battle was fought between the U.S. Army's Army of the Cumberland under Maj. Gen. William Rosecrans and the Confederate Army of Tennessee under Gen. Braxton Bragg, and was named for Chickamauga Creek. The West Chickamauga Creek meanders near and forms the southeast boundary of the battle area and the park in northwest Georgia. (The South Chickamauga ultimately flows into the Tennessee River about 3.5 miles (5.6 km) northeast of downtown Chattanooga).

William Tecumseh Sherman (/tɪˈkʌmsə/ tih-KUM-sə; February 8, 1820 – February 14, 1891) was an American soldier, businessman, educator, and author. He served as a general in the Union Army during the American Civil War (1861–1865), earning recognition for his command of military strategy but criticism for the harshness of his scorched-earth policies, which he implemented in his military campaign against the Confederate States. British military theorist and historian B. H. Liddell Hart declared that Sherman was "the most original genius of the American Civil War" and "the first modern general".

Born in Lancaster, Ohio, into a politically prominent family, Sherman graduated in 1840 from the United States Military Academy at West Point. In 1853, he interrupted his military career to pursue private business ventures, without much success. In 1859, he became superintendent of the Louisiana State Seminary of Learning & Military Academy, now Louisiana State University, but resigned when Louisiana seceded from the Union. Sherman commanded a brigade of volunteers at the First Battle of Bull Run in 1861, and then was transferred to the Western Theater. He was stationed in Kentucky, where his pessimism about the outlook of the war led to a breakdown that required him to be briefly put on leave. He recovered and forged a close partnership with General Ulysses S. Grant. Sherman served under Grant in 1862 and 1863 in the Battle of Fort Henry and the Battle of Fort Donelson, the Battle of Shiloh, the campaigns that led to the fall of the Confederate stronghold of Vicksburg on the Mississippi River, and the Chattanooga campaign, which culminated with the routing of the Confederate armies in the state of Tennessee.

The city of St. Louis was a strategic location during the American Civil War, holding significant value for both Union and Confederate forces. As the largest city in the fiercely divided border state of Missouri and the most important economic hub on the upper Mississippi River, St. Louis was a major launching point and supply depot for campaigns in the Western and Trans-Mississippi Theaters.

Sterling Price (September 20, 1809 – September 29, 1867) was an American politician and military officer who was a senior officer of the Confederate States Army, fighting in both the Western and Trans-Mississippi theater of the American Civil War. He rose to prominence during the Mexican–American War and served as governor of Missouri from 1853 to 1857. He is remembered today for his service in Arkansas (1862–1865) and for his defeat at the Battle of Westport on October 23, 1864.

Robert Lowry (March 10, 1829 – January 19, 1910) was an American politician and lawyer who served as the 32nd governor of Mississippi from 1882 to 1890. Before entering politics, he was a senior officer of the Confederate States Army who commanded infantry in the Western Theater of the American Civil War.
