At 11.15 on the morning of 3 September 1939, Prime Minister Neville Chamberlain broadcast to the nation from 10 Downing Street. His voice was flat with exhaustion and something approaching despair. Britain had delivered an ultimatum to Germany demanding the withdrawal of troops from Poland. No such undertaking had been received. Consequently, he said, this country is at war with Germany. Within hours, the air raid sirens sounded over London. It was a false alarm, but it set the psychological tone for what was to come.
The first eight months of the war — the Phoney War — were a period of uneasy stasis on the Western Front, broken in April 1940 when Germany invaded Denmark and Norway. The disastrous British and French intervention in Norway led directly to the parliamentary crisis that brought down Chamberlain and elevated Winston Churchill to the premiership on 10 May 1940 — the same day that Germany launched its devastating assault through the Ardennes, bypassing the Maginot Line and driving to the Channel coast with a speed that paralysed Allied command.
The evacuation of Dunkirk in late May and early June 1940 rescued 338,000 British and Allied troops from the beaches of northern France using a fleet of naval vessels and the famous armada of small civilian boats. Churchill, in the House of Commons, refused to present it as a triumph — wars are not won by evacuations — but he transformed it into a statement of defiance. We shall fight on the beaches, he said, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender. The speech made a virtue of catastrophe and gave a shattered army the narrative of heroism it needed to continue.
The Battle of Britain, fought in the skies over southern England from July to October 1940, was the decisive engagement that determined whether Germany could invade. The Luftwaffe sought to destroy the Royal Air Force as a precondition for a Channel crossing. The RAF's Fighter Command, with its Spitfires and Hurricanes guided by a sophisticated radar and ground control network, inflicted losses the Luftwaffe could not sustain. By October Hitler had postponed the invasion indefinitely. Churchill's tribute to the fighter pilots — Never in the field of human conflict was so much owed by so many to so few — entered the language permanently.
The Blitz that followed — the German night bombing campaign against British cities from September 1940 to May 1941 — killed over 43,000 civilians and destroyed or damaged over a million homes. London was bombed for 57 consecutive nights. Coventry was devastated in a single night. Liverpool, Birmingham, Plymouth, Bristol and other cities suffered repeated attacks. The civilian population's endurance of the bombing — the Blitz spirit, as it was called — became a cornerstone of British wartime mythology, though the reality included genuine panic, looting and psychological breakdown alongside the genuine courage and community solidarity that the myth emphasised.
Victory in Europe on 8 May 1945 was achieved after six years of war that had cost Britain approximately 450,000 dead, the liquidation of its overseas investments, the beginning of the end of empire and a physical exhaustion that would shape British politics and economics for a decade. The National Health Service, the welfare state and the post-war settlement were as much a product of the collective experience of total war — the sense that a society that had sacrificed together deserved to be cared for together — as of any ideological programme.
