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.
New factories sprung up across Britain and Europe as each combatant sought to out-produce each other to feed their armies with the weapons, equipment and supplies. Producing equipment for allies was also a burden combatants like Britain had to shoulder.

As the scale and the duration of the First World War escalated, the priority for every combatant nation was to ensure that their armed forces had sufficient weaponry, supplies and equipment.
In Britain, the newly-created Ministry of Munitions assumed authority over all elements of war production, from appropriating raw materials to building new factories. Among the Central Powers, the military generally took control of industry. With so many men in the armed forces, women were increasingly called upon to 'serve' in the factories. But despite the widespread support for the war and improvement in wages experienced by many workers, discontent over pay and conditions caused industrial unrest.
The effectiveness of the escalation in war production was immense is illustrated by the quantities of material manufactured: Britain alone produced nearly four million rifles, a quarter of a million machine guns, 52,000 aeroplanes, 25,000 artillery pieces and over 170 million rounds of artillery shells by the end of the war.
Every combatant army on the fighting fronts was dependent on its civilian army in the factories on the home front to sustain it in the pursuit of victory.


Female workers at the National Filling Factory at Chilwell, Nottinghamshire, in July 1917. This factory was one of hundreds of Ministry of Munitions-controlled factories established during the war years. Hundreds of thousands of shells were filled with TNT here. The dangers of this kind of war work were starkly revealed when a massive explosion killed over 130 people at the Chilwell factory.

A Shell Forge at a National Projectile Factory, Hackney Marshes, London, 1918, by Anna Airy. The artist Anna Airy was one of the first women to be officially commissioned to paint war pictures. She later recalled that when working on this painting she had '...never felt such heat! The floor got "black hot". I burnt a pair of shoes right off my feet! You have to paint these red-hot shells so very fast because of the colour changing…’.

Poster appealing for war workers and showing the different ways in which people could contribute to the war effort. Working in war industry was considered every bit as vital as waging war on the fighting fronts. Those on the front line were totally reliant on the mass-produced munitions, equipment and supplies made back home. Some industries, like coal, were considered so important that their workers were not allowed to leave to join the forces.

'On War Service' lapel badge marked 'War Munition Volunteer'. These badges were issued by the British government and private firms. By wearing one, workers were easily identified as being engaged in essential war work. Those who were not 'doing their bit' on the home front were treated with hostility, given the mass support for the war.
