The Marquis de Turenne was a pre-war cavalryman who transferred to aviation after the war began. In June 1916, he was assigned to Escadrille 48 as a Nieuport pilot. He scored his first victory on 17 November 1916; by 30 September 1917, he had half a dozen to his credit. Five of them were shared, with fellow aces Jean Matton, Gilbert de Guingand, and Rene Montrion. De Turenne then transferred to Escadrille 12 as its commander. In his nine victories with this squadron, he continued teamwork in combat and branched out to become a balloon buster by downing two observation balloons. He not only shared victories with fellow aces Marcel Marc Dhome and Emile Regnier, but with several other pilots. An interesting sidelight on de Turenne's victory list is that he had only two solo victories, and there were no fewer than fifteen other pilots sharing one or more of the other thirteen triumphs.
