August. Promoted to brigadier general of volunteers the following month, Wright was assigned as Chief Engineer to Maj. Gen. Thomas W. Sherman's November 1861 expedition against Port Royal, South Carolina. His successes while commanding Union troops in operations against Jacksonville, St. Augustine, and other military targets on the Florida coast from February to June 1862 led to his appointment as major general of volunteers and commander of the Department of the Ohio in August 1862, and commander of the newly created Army of the Ohio in March 1863.

Jubal Early's raid on July 11 and July 12, 1864, commanding the Washington Emergency Defense Force, consisting of the VI, VIII, and XIX Corps. During the defense of Fort Stevens, he gained notoriety by inviting President Abraham Lincoln to join him on a parapet exposed to enemy fire. (A young staff officer, Oliver Wendell Holmes, is often said to be responsible for yelling at the president to get under cover. In George Thomas Stevens's post-war (1870) history of the VI Corps, Wright related to Thomas that he himself was the
