WORLD HISTORY

Detailed explanation-1: -trench warfare, warfare in which opposing armed forces attack, counterattack, and defend from relatively permanent systems of trenches dug into the ground. The opposing systems of trenches are usually close to one another.

Detailed explanation-2: -Strategy. The fundamental strategy of trench warfare was to defend your own position strongly while trying to achieve a breakthrough into the enemy’s rear. The effect was to end up in attrition; the process of progressively grinding down the opposition’s resources until, ultimately, they are no longer able to wage war.

Detailed explanation-3: -The area between opposing trench lines (known as “no man’s land") was fully exposed to artillery fire from both sides.

Detailed explanation-4: -During World War I, trench warfare was a defensive military tactic used extensively by both sides, allowing soldiers some protection from enemy fire but also hindering troops from readily advancing and thus prolonging the war.
