WORLD HISTORY

Detailed explanation-1: -Machine guns and rapid-firing artillery, when used in combination with trenches and barbed-wire emplacements, gave a decided advantage to the defense, since these weapons’ rapid and sustained firepower could decimate a frontal assault by either infantry or cavalry.

Detailed explanation-2: -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. Trench warfare was the major combat tactic in France and Belgium.

Detailed explanation-3: -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.
