J Battery RHA, 1914. These guns are deployed in open positions, typical of the early days of the war, and still useful from time to time later. The problem of being in full view of the enemy is obvious. Open positions were useful again in mobile warfare in 1918. When the British were retreating, the German communications were too weak to pass along news of where British guns were, so the German infantry had to fight the guns alone. When the Germans were retreating, much of their artillery had been destroyed or captured and the communications network was even weaker.
