Trench warfare during World War I involved both sides digging trenches for protection from mines, barbed wire, and enemy fire. Soldiers lived in miserable conditions in the flooded, rat-infested trenches and faced horrors like disfigured corpses and the constant threat of gas attacks. One brief moment of peace occurred during the Christmas truce of 1914, when British and German troops spontaneously emerged from their trenches to exchange gifts and songs on Christmas Day, though the warfare resumed the next day.
