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.

When war broke out in 1914 there were many women in the workforce but many jobs and professions were closed to them. Before the war most women’s work tended to fall into traditional female categories such as social work, nursing, teaching, dressmaking, secretarial work and domestic service. It was deemed unacceptable for married women to work.
The outbreak of war in 1914 saw a huge demand for production of military materiel, a need which escalated as the scale and the duration of the war increased. With so many men called to the fighting fronts, women were recognised as a valuable resource to maintain vital war industries, and they demanded to be allowed to play their part. Soon women were employed in an array of different jobs.
Women’s vital contribution to the war effort was recognised across society, with David Lloyd George, later the Prime Minister, saying in July 1915, 'Without women, victory will tarry'. By the armistice in 1918, over 80,000 women had volunteered for war service. More than 100,000 others had served as nurses, 113,000 worked on the land, 900,000 in munitions factories and 117,000 in transport services.


Women police inspectors were responsible for searching female munitions workers for dangerous items such as matches and for maintaining discipline in and around factories and hostels.

Shells were required in vast numbers at the front, a need met by the workers at home. This dump of empty shell cases at Fricourt in September 1916 shows the enormous quantities required.
