On 1 April 1915, an MoS-3 piloted by Sergeant Jean Navarre took to the skies - where it encountered a German Albatros B.II. Some sharpshooting by the observer, Lieutenant Jean Robert, brought down the biplane - leading to the capture of the craft and its occupants, and the first victory for the MS 12 Escadrille, and medals for Navarre and Robert.
