19 November 1917: “Camouflaged French 75’s being used by the American 6th Field Artillery, 1st Division. Gypse Hill, near Einville, Meurthe et Moselle, France.”
Note the detail which shows these redlegs, including two NCOs, in a mixture of emotion towards themselves and the camera, belaying the fact that it is a candid shot rather than posed. Further note their M1911s on cavalry-style M1912 holsters.
Constituted in 1798 and later became the first horse artillery in the Army, the 6th Field Artillery was assigned 8 June 1917 to the 1st Expeditionary Division (later the Big Red One) and would go on to earn honors for actions at Montdidier-Noyon, Aisne-Marne, St. Mihiel, Meuse-Argonne, Lorraine, and Picardy.
