Rosecrans, William S.
Promoted to major general, Rosecrans assumed command of the Army of the Cumberland in late October 1862. Charged with regaining middle and eastern Tennessee for the Union, he advanced from Nashville in December and precipitated the Battle of Stones River. After two days of intense fighting, he successfully held the field, thereby winning the Union's only military triumph at the end of 1862.
Six months later, Rosecrans resumed his advance toward Chattanooga, Tennessee. Clearing middle Tennessee in the masterful Tullahoma campaign, he next lunged across the Tennessee River into Georgia, driving Confederate forces from Chattanooga. Incautiously continuing his advance until confronted by a reinforced Army of Tennessee, he was attacked on Chickamauga Creek—the Battle of Chickamauga—in late September. Nearing exhaustion, he issued a faulty order that collapsed his line and forced him from the field while much of his army still resisted. Relieved of command in October, he was given the Department of Missouri in 1864 but did not distinguish himself during a Confederate raid.
Postwar, Rosecrans served variously as minister to Mexico, register of the Treasury, congressman, and California rancher. Brilliant but erratic, touted before Chickamauga as a potential general in chief or presidential candidate, Rosecrans saw his military career essentially ended by a single error in judgment on 20 September 1863.

Rosecrans, William Starke
William Starke Rosecrans (rōz´krănz), 1819–98, Union general in the American Civil War, b. Kingston, Ohio. He served in the army from 1842 to 1854 and in Apr., 1861, rejoined as a volunteer. He became aide-de-camp to Gen. George B. McClellan and helped to organize the Ohio Home Guards. Made a brigadier general (May, 1861), he operated successfully against the Confederates in W Virginia (July, 1861–Apr., 1862). As commander of the Army of the Mississippi, he was victorious at Iuka and Corinth (Sept.–Oct., 1862). In Nov., 1862, Rosecrans succeeded to command of the Army of the Cumberland (formerly called the Army of the Ohio) and one month later opposed Braxton Bragg in the battle of Murfreesboro, which ended in a Confederate retreat. In the Chattanooga campaign, he ably outmaneuvered Bragg for a time, but the Confederates thoroughly defeated him at Chickamauga (Sept., 1863). Relieved of his command, Rosecrans for a time directed operations in Missouri. After resigning from the army in 1867, he became minister to Mexico (1868–69), Congressman from California (1881–85), and register of the Treasury (1885–93).
