Trench warfare dominated World War I, particularly on the Western Front between Germany and Allied forces. Soldiers lived in long, narrow trenches dug into the ground, facing horrific conditions—mud, rats, and constant shelling. The "no man's land" between trenches was extremely dangerous. Offensives gained little ground but caused massive casualties.
Battles like the Somme and Verdun highlighted the futility and brutality of this strategy. Trench warfare led to a war of attrition, stalling frontlines for years and making WWI a grim, stagnant conflict.
