'Dragging the Guns to New Advance Positions', (1919). Scene from the First World War, 1914-1919: '"Our greatest enemy," said many an officer home on leave from the front, "was the mud", which is here wonderfully exemplified. In the wet, slimy, sticky mess, churned and pounded to porridge, horses, men, and wheels sink and wallow. Man power and "catterpillar" wheels materially lessened the difficulties, which were great indeed.' 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]
