'One of the Monster British Guns', (1919). Scene from the First World War, 1914-1919: heavy artillery mounted on a train. 'The tremendous engines of destruction used on our Battleships were also brought into the field, and to all intents and purposes the weapon mounted on its carriage constituted a land battleship hurling death and destruction on vulnerable points far into the German lines.' From "The History of the Great European War: its causes and effects", Vol. V, by W. Stanley Macbean Knight. [Caxton Pulishing Company, Limited, London, 1919]
