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.

Recruiting Officers were paid for each man so some turned a blind eye to underage volunteers. The British government had originally said that no one under 19 years of age would be sent overseas to fight. In April 1918 they lowered the age to 18 after suffering a near-defeat on the Western Front. This photograph was taken in July 1918, when the army were trying to find and remove underage soldiers.

As the war went on the British Government had to persuade more and more men to go to war. The Derby scheme was introduced in Britain in October 1915 and asked men to register their commitment to serve Under the scheme single men would be called up before married volunteers.

In Britain and the Dominions the issue of conscription (forced military service) caused much controversy. Conscription was finally introduced in Britain and New Zealand in 1916, and in Canada in 1917, although it was not introduced in Australia.

Conscription was a hugely controversial step. Conscientious objector’s refused to fight on religious or moral grounds, although the proportion of conscientious objectors to men in uniform was very small. This membership card for the No-Conscription Fellowship belonged to William Harrison, who went to prison because he refused to have anything to do with the war. He was a pacifist whose deep religious beliefs told him that killing was wrong.

Women took on jobs that had previously been done by husbands, brothers and fathers, who were now absent, as well as keeping households and families together. This painting by Randolph Schwabe shows two women of the Women's Land Army and two German prisoners-of-war doing important agricultural work.

A number of the leading Suffragettes played an important role in setting up women-only organisations to support the war effort. Their success influenced the decision to create branches of the armed services for women. The first of these was the Women’s Army Auxiliary Corps (WAACs), which was formed in January 1917.
