Supposed to be the war that ended all wars, WW1 (World War 1) as it became known, though
referred to as the Great War at the time, saw 17 million killed (of which 7 million were
civilians) and a further 20 million injured. WW1 lasted from 28th July 1914 until the Germans surrendered on 11th November 1918. During that time a staggering 70 million
personnel were mobilised by the British, French and Russians on one side
(later to be joined by the Americans) and Germany and Austria Hungary
on the other.
