trenches... trench warfare.... what exactly do you need?
The soldiers themselves dug out the trenches.
Because there is something called a Stalemate. Both sides cannot advance so they dug trenches and stayed there.
both sides were locked in a stalement
I assume the question is about the trenches used in World War I? Both sides of the conflict reached a stalemate and dug protective trenches. The number of soldiers killed and maimed (on both sides) was tremendous and proved the futility and waste of warfare, as frontal attacks moved the front back and forth.
Yes, because the two sides were very evenly matched for much of World War 1.
I assume you mean the western front in Europe. It didn't move much because both sides were dug into trench systems and everything became bogged down.
Both sides of the conflict.
