Explanation:
The trenches were an invention during the time of the first world war when the soldiers began to dig into the fields and fight from them instead of open pitched battle which was common in the time.

This was to be worked around by using more war fronts to surround and bypass the trenches as well as ways to mount the other trenches and overtake them.
