How long did trenches take to dig?

The time it took to dig trenches during World War I varied depending on factors such as the type of terrain and the availability of tools and manpower. Typically, soldiers could dig about 2 to 3 feet of trench per day under combat conditions, but with more time and resources, deeper and more complex trenches could be constructed in a matter of weeks. Overall, complete trench systems could take several weeks to months to establish fully.
