Those lovely valleys and mountains were filled throughout the day and night with the roar of heavy shooting. Sometimes there were uncanny silent spells of an hour or more. Then it would start up again across the country with violent fury. On my first night at the front I slept only fitfully – never very wide awake, never deeply asleep. All night long the valley beside us and the mountains and the valleys over the hill were dotted and punctured with the great blasts of the guns.
