All day the sky is hung with observation balloons. There is a rumour that the enemy are going to put tanks over and use low-flying planes for the attack. But that interests us less than what we hear of the new flamethrowers.

We wake up in the middle of the night. The earth booms. Heavy fire is falling on us. We crouch into corners. We distinguish shells of every calibre.

Each man lays hold of his things and looks again every minute to reassure himself that they are still there. The dugout heaves, the night roars and flashes. We look at each other in the momentary flashes of light, and with pale faces and pressed lips shake our heads.

Every man is aware of the heavy shells tearing down the parapet, rooting up the embankment and demolishing the upper layers of concrete. When a shell lands in the trench we note how the hollow, furious blast is like a blow from the paw of a raging beast of prey. Already by morning a few of the recruits are green and vomiting. They are too inexperienced.
