When established in a fixed defensive position and sited specifically to cover potential enemy attack routes it was a fearsome weapon. Infantry assaults upon such positions invariably resulted in high casualties.

By 1899 the photographs were mounted on thick card that was given a slight curvature to increase the illusion of depth. Associated with World War One, Western Front (1914-1918).
