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.
Joan 'Elizabeth' Mortimer, Elspeth Henderson and Helen Turner of the WAAF. All three received the Military Medal for courageous conduct during attacks on Biggin Hill airfield. Biggin Hill suffered a total of ten major attacks between 30 Aug and 5 Sept.
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.
This photograph taken early in 1990 shows the West German flag flying over the Brandenburg Gate, with a graffiti covered section of the Berlin Wall in the foreground. Marks on the wall left by hundreds of Berliners chipping away at the concrete are clearly visible. By the end of the year, much of the Wall had been demolished.

For almost 30 years, the Berlin Wall stood as a physical symbol of the ideological divisions within Europe during the Cold War.
At the end of the Second World War in 1945, Germany had been divided into American, British, French and Soviet zones. Berlin was similarly split and was isolated in the Soviet zone of the country. Despite Soviet intimidation, notably a blockade that led to the Berlin Airlift in 1948-1949, the Western powers were unwilling to surrender their agreed sectors of the city.
On Sunday 13 August 1961, Berliners woke to find that their city had been physically divided by the closure of established crossing points and a makeshift barrier of barbed wire. Over the following months and years this barrier developed into a heavily guarded concrete wall fortified with watchtowers and bordered by the 'death strip' – a mined area of gravel under constant surveillance. The main reason for the construction of the wall was to prevent East Germans fleeing to the freer and more affluent West via West Berlin.
The wall divided districts and separated families. Over 5,000 escape attempts were made. Some were successful, but over 100 people are known to have died trying to cross the wall.
During 1989, political changes in other Eastern bloc countries and weeks of civil unrest weakened the East German regime. On the evening of 9 November 1989, the Wall opened and East Berliners flocked to the West. German reunification followed on 3 October 1990.


Section of the Berlin Wall on display at IWM London. This section of the Berlin Wall sits outside Imperial War Museum London, and is a great favourite for visitors. The colourful artwork with the positive Change Your Life message was created by the graffiti artist 'Indiano', and is said to have been inspired by a Rainer Maria Rilke poem. The colourful front of the Wall was on the West side, whereas the reverse side – facing East – is dull and grey and forbidding.
