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.

The open nature of warfare in North Africa accentuated the importance of armoured fighting vehicles and artillery.
British tank design was governed by tactical principles which assigned slow but well-protected 'I' tanks to support the infantry, while speedy but lightly armoured 'Cruiser' tanks fought the enemy armour. These tactics persistently failed against the Germans, who preferred to engage tanks with anti-tank guns.
The British tanks were relatively impotent against these, as their 2-pounder guns were unable to fire an effective high-explosive shell. Until May 1942, when the American Grant began to arrive, the British had no tank which was truly effectual in anything but tank-to-tank combat.
Most British tanks were plagued by unreliability. However, the 8th Army was well-served with reconnaissance vehicles – particularly after the appearance of Humber and Daimler armoured cars from late 1941 onwards.
Anti-tank guns were upgraded during the campaign. The original 2-pounder was supplemented by the 6-pounder from 1942 onwards. By 1943 examples of the powerful 17-pounder had been rushed into service, to counter the threat of the German Tiger tank.
With regard to field artillery, the most important piece of British equipment was the efficient 25-pounder gun. Longer range support was provided by medium artillery. Initially this consisted of 60-pounder guns and 6-inch Howitzers of First World War design. By the end of the campaign, these had been superseded by modern 4.5-inch and 5.5-inch guns. From late 1942 self-propelled artillery also became available, in the form of the British Bishop and the American Priest.


A Crusader II tank of 22nd Armoured Brigade photographed returning from action in the Western Desert in July 1942. Much was expected of this fast 'Cruiser' tank, but its performance was blighted by unreliability.

The Grant Tank's 75mm gun provided the much needed capability to fire effective high-explosive shells, although its position in the hull circumscribed the tactical employment of the tank.

This photograph shows a 2-pounder anti-tank gun manned by New Zealanders, December 1941. This is a 'Portee' gun, mounted on a truck. This method of increasing the mobility of anti-tank guns was a feature of the campaign in the desert.

British 4.5-inch and 5.5-inch guns used the same carriage. The former had the longer range, but the latter fired a more destructive shell. This 4.5-inch field gun in shown action south of El Alamein, July 1942.
