Trench warfare
Trench warfare has become archetypically associated with the First World War of 1914–1918, when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914. By the end of October 1914 the whole front in Belgium and France had solidified into lines of trenches, which lasted until the last weeks of the war. Mass infantry assaults were futile in the face of artillery fire as well as rapid rifle and machine-gun fire. Both sides concentrated on breaking up enemy attacks and on protecting their own troops by digging deep into the ground. Trench warfare also took place on other fronts, including in Italy and at Gallipoli.
Artillery of World War I
The artillery of World War I was used primarily to counter the trench warfare that set in shortly after the conflict commenced, and was an important factor in the war, influencing its tactics, and operations, and being incorporated into strategies that were used by the belligerents to break the stalemate at the front. World War I raised artillery to a new level of importance on the battlefield.
