Trench warfare
Trench warfare occurred when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire, mines, camouflaged trapping pits, and other obstacles. The area between opposing trench lines (known as "no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties.

The First World War, which took place between 1914 and 1918, saw the extensive use of artillery, particularly on the Western Front. Technical advances, combined with the relatively static nature of trench warfare, made these guns a key element of the conflict: over half the casualties in the war were caused by artillery. Artillery guns and their crews were themselves targets, however, and 49,076 members of the Royal Artillery died during the conflict. In the years after the war, many former servicemen, including gunners, found the scale of the losses difficult to deal with, or felt that the events challenged their trust in the political leadership that had led them into the war. Visual reminders of the conflict were often avoided: mutilated servicemen, for example, were banned in the 1920s from joining in veterans' marches, and those with facial injuries often hid them in public.
