text: World War I The British Army did not widely employ the term when the Regular Army arrived in France in August 1914, soon after the outbreak of World War I. The terms used most frequently at the start of the war to describe the area between the trench lines included 'between the trenches' or 'between the lines'. The term 'no man's land' was first used in a military context by soldier and historian Ernest Swinton in his short story "The Point of View". Swinton used the term in war correspondence on the Western Front, with specific mention of the terms concerning to the Race to the Sea in late 1914. The Anglo-German Christmas truce of 1914 brought the term into common use, and thereafter it appeared frequently in official communiqués, newspaper reports, and personnel correspondences of the members of the British Expeditionary Force (BEF).
  In World War I, no man's land often ranged from several hundred yards to less than , in some cases.  Heavily defended by machine guns, mortars, artillery, and riflemen on both sides, it was often extensively cratered by exploded shells, riddled with barbed wire, and littered with rudimentary land mines; as well as the corpses and wounded soldiers who were unable to make it through the hailstorm of projectiles, explosions, and flames. The area was sometimes contaminated by chemical weapons. It was open to fire from the opposing trenches and hard going generally slowed any attempted advance.
