World War I, also known in its time as the “Great War” or the “War to End all Wars”, was an unprecedented holocaust in terms of its sheer scale. Fought by men who hailed from all corners of the globe, it saw millions of soldiers do battle in brutal assaults of attrition which dragged on for months with little to no respite. Tens of millions of artillery shells and untold hundreds of millions of rifle and machine gun bullets were fired in a conflict that demonstrated man’s capacity to kill each other on a heretofore unprecedented scale.

Since the industrial revolution, arms and materiel output had increased by orders of magnitude, as had the quality and uniformity of the products. Several developments had already taken place in the years building up to the conflict, stepping stones towards the vast escalation in military innovation which took place immediately prior to and during World War I. Innovations included the adoption into service of the first belt-fed machine guns, predecessors of those which would wreak such slaughter in the trenches, and the development of cannon which did not roll backwards after each shot as 19th century pieces did, but remained fixed in place.

The arms race before the war and the attempt to break the deadlock of the Western and Eastern Fronts by any means possible changed the face of battle in ways that would have previously been deemed unthinkable. Before 1914, flying machines were objects of public curiosity; the first flights of any account on rotor aircraft had been made less than 5 years before and were considered to be the province of daredevils and lunatics. By 1918, all the great powers were fielding squadrons of fighting aircraft armed with machine-guns and bombs, to say nothing of light reconnaissance planes. Tanks, a common feature on the battlefield by 1918, had not previously existed outside of the realm of science fiction stories written by authors like H.G. Wells.
