Oliver Otis Howard (1830-1909) was a Union general during the American Civil War. He commanded the XI Corps of the Army of the Potomac at the battles of Chancellorsville and Gettysburg (The corps was routed at both battles, causing the Union lines of which it was part to collapse. This led many observers to underestimate Howard's competence.) and continued to command the corps when it was detached from the Army and sent west in the fall of 1863, to serve with William Sherman's forces. He was with Sherman on the "March to the Sea".
After the Civil War, Howard fought the Nez Perce, and founded Howard University.
