The first trenches of World War I were dug by soldiers using shovels and pickaxes, often under dire conditions and the threat of enemy fire. Initial trenches were relatively shallow and rudimentary, primarily constructed to provide some protection from artillery and small arms fire. As the war progressed, they evolved into complex networks with deeper, more fortified positions, complete with amenities like communication lines, supply routes, and medical stations. The design and construction of trenches were influenced by the need for defensive strategies and the harsh realities of trench warfare.
