How did the trenches help soldiers for survival?
The structure of trenches was a crucial step for survival in WW1. The design and structure of the trenches were never dug in straight lines. The purpose of this design is to enable soldiers to lose one part f the trench, and allow the soldiers to fall back and defend the rest of the trench. This design allows soldiers to take cover from firing with plenty of protection. The support trenches were a extensive factor in soldiers being well fed and supplied with ammunitions. The majority of trenches that were dug by soldiers in WW1 were extremely deep and heavily and structurally reinforced to protect themselves from bombing and the artilleries. The front part of the trench was called a parapet. The leading edges of the parapet (front) and paraods (back) would be reinforced with sandbags. This was designed to provide extra protection from bullets and bombs which could severly injure or kill a soldier. The bottom of the trench was covered with wood and timber. This design was created to prevent the trench foot disease. A few meters in front of the front trench was barbed wire. This was a key feature of the trench structure and design because it helped to slow down the on coming charge of the enemies soldiers and give time for the troops to pick off the enemy.
