The trenches were a crucial part of the defensive strategy in World War I as a response to the new and deadly weapons of war such as machine guns, long-range artillery, and poison gases.
The German troops dug deeper and more elaborate trenches, indicating a long-term defensive strategy. Conversely, the early Allied trenches were rudimentary but evolved over time.
