The Somme Theatre was the last, longest and most bloody of the continenatl theatres of the Great War. The Theatre was, for over three-fourths of its life, a long-lasting front, with large trenches causing large levels of casualties for the population. In the Somme, the French threw every man they could spare to fight against the invasion forces, leading to a casualty rate of almost 50% amongst the population (in comparison to a 33% casualty rate amongst the Allied forces). With large-scale levels of combat and extremely destructive fighting for both sides, the Somme Theatre immortalised the Great War as one of the most devastating moments of human history. The Somme Theatre eventually completely sapped the morale of French soldiers, leading to the French side of the Autumn Revolutions and the surrender of the French State to Allied forces.
