William Rosecrans

Who was William Rosecrans?

William Starke Rosecrans was an American inventor, coal-oil company executive, diplomat, politician, and U.S. Army officer. He gained fame for his role as a Union general during the American Civil War. He was the victor at prominent Western Theater battles, but his military career was effectively ended following his disastrous defeat at the Battle of Chickamauga in 1863.

Rosecrans was a graduate of West Point who served as a professor at the academy and in engineering assignments before leaving the Army to pursue a career in civil engineering. At the start of the Civil War, leading troops from Ohio, he achieved early combat success in western Virginia. In 1862 in the Western Theater, he won the battles of Iuka and Corinth while under the command of Maj. Gen. Ulysses S. Grant. His brusque, outspoken manner and willingness to quarrel openly with superiors caused a professional rivalry with Grant that would adversely affect Rosecrans' career.

Given command of the Army of the Cumberland, he fought against Confederate Gen. Braxton Bragg at Stones River, and later outmaneuvered him in the brilliant Tullahoma Campaign, driving the Confederates from Middle Tennessee.
