The rest of the War
He was promoted from Captain to Major on 5 February 1863, and put in command of the First Brigade of the artillery reserve of the Army of the Potomac. On 23 June 1863 he was made Lieutenant Colonel, and full Colonel 1 September 1863. He led his command in the Battles of Chancellorsville, Gettysburg, and Mine Run. His performance on the 2nd Day of Gettysburg is considered his finest hour.
By 1864 he was Chief of Artillery, X Corps. He was wounded at Deep Bottom, Va., 16 August 1864, and died about two weeks later from effects of chloroform during amputation of a finger. Ft McGilvery, part of the Federal works at Petersburg built that month, was named for him.
