The Commanding Generals

Braxton Bragg, commanding General of the Confederate Army of Tennessee

Braxton Bragg commanded the Confederate Army of Tennessee at the Battle of Chickamauga and the Battles for Chattanooga. He was a graduate of West Point (Class of 1837), a Seminole War veteran, a distinguished veteran during the Mexican-American War, and a long-standing United States Army officer. Bragg resigned from the army in 1856 and was overseeing his Louisiana plantation when the war began.

In 1861, he was appointed and confirmed a brigadier general in the Provisional Army of the Confederate States and was placed in command of the defenses along the Gulf Coast (from Pensacola, Florida, to Mobile, Alabama). Bragg was promoted to major general in September 1861 and assisted General Albert S. Johnston at Shiloh in April 1862. Soon after the battle, he was elevated to the rank of general and, in June, replaced General P.G.T. Beauregard as commander of the Army of Mississippi, later renamed the Army of Tennessee. He led this army into Kentucky, where he met defeat at the Battle of Perryville in October 1862. His next major battle was fought against Major General William S. Rosecrans along the banks of Stones River, Tennessee (December 31, 1862, & January 2, 1863). After being pushed out of Middle Tennessee and Chattanooga, Bragg defeated Rosecrans at the Battle of Chickamauga, fought September 18, 19, & 20, 1863. He then besieged the Union army in Chattanooga until November, when forces under the command of General U.S. Grant forced him to retire into Georgia. He resigned his command and Joseph E. Johnston took his place as commander of the Army of Tennessee. President Jefferson Davis called Bragg to Richmond where he was placed under the direction of the president "with the conduct of the military operations in the armies of the Confederacy." At the end of the war, Bragg found his way back into the field, seeing further service in North Carolina.

William Rosecrans, Commanding General of the Union Army of the Cumberland

Prior to the American Civil War, William Rosecrans was a United States Army officer, inventor, and engineer. "Old Rosey," as he came to be known, graduated fifth in his class from West Point in 1842 (a class that boasted future generals James Longstreet, Daniel H. Hill, Richard H. Anderson, Abner Doubleday, Alexander P. Stewart, and Earl Van Dorn), and entered the United States Army. His first assignment was at Fortress Monroe, Virginia, as an engineer. Soon after, he requested an appointment to teach at West Point, which was granted. There, he taught engineering and served as post commissary and quartermaster. He suffered from poor health and resigned from the army in 1854. After which, he held several civilian positions. He took over a mining business in western Virginia, helped build one of the first oil refineries west of the Allegheny Mountains, and obtained several patents for inventions. In 1859, while serving as president of the Preston Coal Oil Company, Rosecrans was severely burned after an experimental "safety" oil lamp exploded that set the refinery on fire. It took him eighteen months to recover, and facial scaring left him with the appearance of having a perpetual smirk.

However, when war came, Rosecrans offered his services to the Union. He briefly commanded the 23rd Ohio Infantry but was soon promoted to brigadier general in the regular army. After successfully fighting his first engagement at Rich Mountain, Virginia, Rosecrans requested a transfer to the West. He was placed in command of the left wing of the Army of the Mississippi at Iuka and Corinth. Animosity between U.S. Grant and Rosecrans was heightened after Corinth in 1862 due to Grant blaming Rosecrans for not pursuing the Confederate Army and Rosecrans placing blame on Grant for not sending proper reinforcements during and following the battle. After Corinth, Rosecrans was promoted to major general of the XIV Corps, his promotion being back dated to March 1862, so he could outrank Major General George Thomas. He secured a major victory at the Battle of Stones River (Murfreesboro, Tennessee) and reorganized the XIV Corps into the newly named Army of the Cumberland. In the summer of 1863, Rosecrans moved against the Confederates under General Bragg, taking Middle Tennessee and the City of Chattanooga with less than 600 casualties. Rosecrans' fatal mistake came during the Battle of Chickamauga, when he ordered troops to fill a gap in the Union line. Unknown to Rosecrans, his order created an actual gap in the line, through which Confederates under the command of Lieutenant General James Longstreet poured. The Army of the Cumberland was shattered, retreated to Chattanooga, and was besieged. Rosecrans was relieved of command and placed in charge of the Department of Missouri until the war's end.
