One reason for the large scale of destruction of the First World War was a sudden advance in weapon technology, especially that of the machine gun, which led to trench warfare. Many frontiers of the war were behind others technologically even to the point of entering the war, wearing old fashioned uniforms and using old fashioned weaponry. The effect this had was one of an all out massacre, as soldiers in bright coloured costumes, sometimes on horseback, sometimes brandishing a sword, were no matched for an entrenched line of machine gun wielding, well uniformed soldiers. With this change of style of warfare came a change in values and the war became increasingly ugly as it became more about winning at whatever the cost and less about honourable conduct. This had a lasting effect, as armies became slower to engage in such all out massacres, but sadly the price of life became cheaper and the scale of massacre became ever greater with the Second World War.
