  • Destroyed German concrete dugout, near Hill 60, 27 August 1917. This is what heavy artillery could do: a 9.2″ shell destroyed a German dugout with two feet of concrete reinforcement that had been ten feet underground. However, it took a long time to destroy any substantial percentage of these defenses, and the Germans built many pillboxes. Source: IWM photo E665.
