The conditions in which soldiers lived and slept varied greatly depending on the theater of war. In the trenches, soldiers lived in dugouts, which were holes dug into the ground and covered with a waterproof sheet or tarpaulin. These dugouts were often cramped and uncomfortable, and soldiers had to sleep in shifts due to the limited space. In some cases, soldiers were forced to sleep in the open air, exposed to the elements.
In other locations, such as behind the lines or in temporary camps, soldiers might have access to more comfortable sleeping arrangements. They might sleep in tents, barracks, or other shelters provided by the military. In some cases, soldiers were able to requisition housing from local civilians.
Regardless of the specific conditions, sleep was often a scarce commodity for soldiers during World War 1. The constant threat of attack, combined with the physical and emotional strain of combat, made it difficult for many soldiers to get a good night's rest.
