60-pounder firing a barrage, near Moeuvres, dawn of 27 September 1918. After 1916, one of the main uses of 60-pounders was adding depth to the creeping barrage. With greater range than the 18-pounders, the 60-pounders could hit specific targets ahead of the main barrage, to suppress them, restrict the movement of German reserves, or destroy particular targets. On the right horizon a field battery is moving forward, likely to become a direct-support battery or take up an advanced position to fire a later stage of the creeping barrage, something that was possible in 1918 but would have been suicidal in 1917.
