The sight of front-line barbed wire remains a powerful image of the Great War. In the early stage of the war the use of so-called ‘Chevaux de Frise‘ (or knife-rests as they were known by the British) enabled soldiers to prepare barbed wire defences behind the lines and bring them up, putting them in place at night. Being portable they could also be moved.

Few survive intact but this section is part of a reconstructed French trench system in the Champagne which saw heavy fighting in 1915.
