"Existence" image: two British infantrymen sit and smoke in a dugout in a Western Front trench. A dead rat lies on the ground in the trench outside. The dugout is constructed from sandbags, earth and corrugated iron, with a tarpaulin also making up part of the roof. The two men huddle together, partly due to the cramped space and partly for warmth. The face of the man to the right is obscured by the dugout roof, the man to the left is shown wearing a balaclava.
