'An enemy blockhouse seized at Poelecappelle is quickly converted into a machine-gun nest', 1917

Stereoscopic photograph, World War One, Western Front (1914-1918), 1917.

The machine-gun was one of the dominant weapons on the First World War battlefield. When established in a fixed defensive position and sited specifically to cover potential enemy attack routes it was a fearsome weapon. Infantry assaults upon such positions invariably resulted in high casualties.
