After defeating France in June 1940, Hitler assumed Britain would sue for peace but ordered his armed forces to prepare for invasion. Hermann Goering assured him that a sustained air assault would destroy the RAF, winning the air superiority needed.
July 1940 saw German planes target shipping in the Channel, drawing the RAF into combat, before radar stations, communications centres and airfields faced round-the-clock bombing in August. The battle reached a climax with attacks on London in September.

A group of pilots of No. 303 (Polish) Squadron RAF return from a sortie. The first Polish squadrons were formed in the summer of 1940. Pilots came from several other countries, including Australia, Canada, Czechoslovakia, New Zealand and the USA.
RAF Duxford was a Sector Station in 12 Group, responsible for defending the Midlands and East Anglia. As the fighting intensified, Duxford's squadrons were called on to support 11 Group's defence of London and the south-east.
Despite incessant attacks, the RAF's defences held. The Luftwaffe could not continue, and in the autumn switched to 'nuisance' raids and night operations. The failure to defeat the RAF convinced Hitler to postpone his invasion plans indefinitely.

'From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the continent.’ Churchill’s words in a 1946 speech recognised that the relationship between the Allies and the USSR had irrevocably changed. The ambition of the Soviet Union to retain former German territory was regarded as provocative. The first major flashpoint was the Berlin Blockade in 1948, where the Allied Airlift prevented the Soviet takeover of the city.
The democratic United States and the Communist Soviet Union were ideologically opposed 'superpowers', and each had their own alliances. The most important of these were the North Atlantic Treaty Organisation (NATO) and the Warsaw Pact. Both sides had nuclear weapons and there was a real fear that they would be used.
Though fighting did not occur in Europe, the superpowers sought to exert their influence around the world. Soviet and US client states fought each other, supplied, advised and sometimes directly helped by the superpowers. The most important of these conflicts were the Korean and Vietnam wars.
The fall of the Berlin Wall in 1989 and the dissolution of the Soviet Union in 1991 brought the Cold War to an end, leaving a legacy of instability all over the world.
