A Pill Box, as described in Soldier and Sailor Words and Phrases, was “the name, from the shape for the German ferro-concrete small battlefield-redoubts or forts, employed from the autumn of 1917 onwards to defend sections of the line in Flanders. Some of the larger were quadrangular in shape. They were garrisoned by small detachments of infantry with machine guns and were proof against anything except a direct hit by a "big gun" such as the infamous Big Bertha, large, heavy siege howitzer. Their capture was often effected by infantry with hand grenades flung into the entrance at the rear, or through the loopholes, while other infantry kept down the German rifle fire by shooting at the loopholes.”
