Life in trenches was horrible. There weren't clean places to sleep in or decent shelters and food. If they didn't have food they usually burned rats to eat them, soldiers were subjects to several diseases due to the water (in which they secreted feces and urine) floating around and the filthy smell of it. Their dead comrades were lying nearby without proper burial.
For the soldiers life in the trenches was really tough. The soldiers shared there beds with mice and rats. Also it was not only summer whilst in the trenches it was also winter meaning frequent rain. This made the soldiers lives umbearable and gave them trench foot. Type that into the internet and you will see how horrific life for the soldiers realy was.
boring, stressful, dirty
Trenches in the Pacific Theater of the war were absolutely vital to save lives. They dug them on every island they fought upon. Trenches in Africa, Italy and during the Normandy Invasion, Battle of the Bulge were critical too. The poor guys in the Battle of the Bulge and in the Ardenne Forest had to literally make snow trenches and even sleep in them. Some of the soldiers even used fallen vehicles for trenches and safe protection. Without trenches hundreds of thousands of men would have died, even if some did die in the trenches, especially when they stood up.
