Many people have the idea that the 'Great War' on the Western Front was simple, if ghastly, to fight - with few tactics, and unbroken, monotonous, trench lines as the main feature of the battlefield. In such a scenario soldiers with rifles and bayonets charging each other in blind obedience to stupid repetitious orders are imagined as archetypal of battle. Though undeniably bloody the war was in fact a ferment of new ideas and new weapons. Gas, flame throwers, super-heavy artillery, concrete bunkers, tanks, aircraft and other innovations were all introduced, whilst older notions such as barbed wire, machine guns and armour took on a new lease of life.
