German bunker in World War 1 on the Western Front. Unlike the allies, the germans lived in relative comfort, creating massive bunker cities underneath the lines, complete with armoures, kitchens, and even running water and electricity if they were near enough to villages. Soldiers were allowed to bring furniture from home, or from destroyed towns, and even wallpapered the wood and earthen walls. Excess rain and waste water was pumped out, and, as the german positions were almost always higher then the allied, was allowed to flow down into the allied trenches. It all stemmed from the differing tactical choices, the allied generals believing, to the end of the war, that trenches were temporary, and duly should not be made to live in, as the men are supposed to be charging forward, while the germans saw trenches are a permanent feature of the war, and duly should be made comfortable for the soldiers to live in.
