'A Mine Crater in High Wood', (1919). Scene from First World War, aftermath of the Battle of Guillemont in northern France, 3 September 1916: 'Something of the terrific power of modern high explosives is here visualised. The introduction of the figures in the picture gives scale to the enormous cavity formed by the explosion and some idea of the mass of debris hurled into the air.' 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]
