Very heavy showers – mud simply astonishing! Each man brings several pounds of it into the bivvy on his boots. You use the word “battle” often. The actions are better described by the slang “stunt” and simply indicate that one section has awakened from a dormant to a bellicose state. You hear “the cooks took part in one battle” – everyone within 5 or more miles of the front line does – the enemy may shell and bomb any where within 20 miles of the front and at times back areas are more dangerous than the trenches. Everything is on far too big a scale to be a battle.
