Photograph, World War One, Western Front (1914-1918), 1917 circa. Moving supplies up to the front line trenches on the Western Front was a dangerous business and men carrying food and drink rations were often targeted by enemy snipers. In some sections of the line, supply convoys would vary the times and routes of their journeys in order to maximise their chances of getting through unscathed.
