What was the trench routine like during the First World War?
Other than when a major action was underway, trench life was usually very tedious and hard physical work. Officers had to ensure that there was if possible a balance between the need for work against the enemy, on building and repairing trench defences and for rest and sleep. This could only be done by a good system with a definite system of rotas and a work timetable. Obviously, in times of battle or extended alerts, such routine would be broken, but these times were a small proportion of the time in the trenches.
The main enemies were the weather and boredom, and the loss of concentration - leaving oneself exposed to sniper fire, for example - could prove deadly. At dawn and dusk, the whole British line was ordered to 'Stand To!' - which meant a period of manning the trench in preparation for an enemy attack. Once the incoming unit had relieved the outgoing one, various precautionary actions would be taken. At least one man in four (at night; perhaps one in ten by day) were posted as sentries on look-out duty, often in saps dug a little way ahead of the main fire trench. They would listen for sounds that might indicate enemy activity, and try to observe such activity across no man's land. The other men would be posted into the fire trench or support trench, in sections. Unless they were a specialist such as a signaller or machine-gunner, men would inevitably be assigned to carrying, repair or digging parties, or sent under cover of dark to put out or repair barbed wire defences.
