English: Trench during World War I. An extremely wet and muddy trench. In the background there is a soldier sheltering from the rain, outside what could be the entrance to a dugout. Sandbags are piled up around the walls of the trench, to prevent collapse. Spades and other implements are strewn across the foreground, and there is a roll of barbed wire behind the burnt and blasted remains of a tree.

Trench warfare was very harsh. A deadlock on the Western Front forced the respective armies to produce massively protected trench systems, and new weapons and tactics had to be devised. At first weaponry was desperately improvised, but then heavy artillery, such as Howitzer guns were brought in to obliterate the enemy's trench system and kill any soldiers on the open ground.
