The accidents of military geography also began to work to the Germans’ disadvantage. The nearer they approached Amiens, the more deeply did they beco… - John Keegan

Within fifteen years of the war’s end, totalitarianism, a new word for a system that rejected the liberalism and constitutionalism which had inspired European politics since the eclipse of monarchy in 1789, was almost everywhere on the rise. Totalitarianism was the political continuation of war by other means.

All European armies in 1904 had long-laid military plans, notable in most cases for their inflexibility. None was integrated with what today would be called a ‘national security policy’, made in conclave between politicians, diplomats, intelligence directors and service chiefs, and designed to serve a country’s vital interests, for such a concept of national leadership did not then exist. Military plans were held to be military secrets in the strictest sense, secret to the planners alone, scarcely communicable in peacetime to civilian heads of government, often not from one service to another.

It is one of the many graveyards which are the Great War’s chief heritage. The chronicle of its battles provides the dreariest literature in military history; no brave trumpets sound in memory for the drab millions who plodded to death on the featureless planes of Picardy and Poland; no litanies are sung for the leaders who coaxed them to slaughter. The legacy of the war’s political outcome scarcely bears contemplation: Europe ruined as a centre of world civilisation, Christian kingdoms transformed through defeat into godless tyrannies, Bolshevik or Nazi, the superficial difference between their ideologies counting not at all in their cruelty to common and decent folk. All that was worst in the century which the First World War had opened, the deliberate starvation of peasant enemies of the people by provinces, the extermination of racial outcasts, the persecution of ideology’s intellectual and cultural hate-objects, the massacre of ethnic minorities, the extinction of small national sovereignties, the destruction of parliaments and the elevation of commissars, gauleiters and warlords to power over voiceless millions, had its origins in the chaos it left behind. Of that, at the end of the century, little thankfully is left. Europe is once again, as it was in 1900, prosperous, peaceful and a power for good in the world.
