Trench Warfare No Man’s Land Area between Trenches Military leaders sent “men over the top” in an attempt to take the other sides trenches Men had to cross no man’s land while being shelled and shot at by machine guns

Trench Warfare Each trench had a listening post at the end, where men would sit at night and listen for any sounds.
Trench Warfare Flooding was a constant problem and this led to numerous cases of rat infestation
Trench Warfare Stalemate Neither side was able to make any major advances on the enemy trenches lead to fighting a war of attrition Cause large numbers of causalities so the enemy gets tired of fighting
