"Photography during the First World War" Troops supposedly "going over the top" at the start of the Battle of the Somme in 1916, photographed by Canadian official photographer Ivor Castle. This photograph was widely and misleadingly published as a portrayal of an actual British attack. However it was actually taken during a training exercise behind the lines. The breech cover which is clearly visible on the rifle of the soldier in the foreground was edited out in contemporary publications of the photograph.
