McConnell was flying in the area of St.-Quentin when two German planes shot him down on March 19, 1917. He was the last American pilot of the squadron to die under French colors before America entered the war in April 1917. Both the plane and his body were found by the French, and he was buried at the site of his death at the edge of the village of Jussy, and was later reinterred at the Lafayette Escadrille memorial near Paris upon his father's wishes. McConnell was commemorated with a plaque by the French Government and a statue by Gutzon Borglum at the University of Virginia, as well as an obelisk on the court square of his home town of Carthage, North Carolina.
