Grabenkrieg
Trench warfare has become a powerful symbol of the futility of war. Its image is of young men going "over the top" (over the parapet of the trench, to attack the enemy trench line) into a maelstrom of fire leading to near-certain death, typified by the first day of the Battle of the Somme (on which the British Army suffered nearly 60,000 casualties) or the grinding slaughter in the mud of Passchendaele. To the French, the equivalent is the attrition of the Battle of Verdun in which the French Army suffered 380,000 casualties.
