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.
Convoy PQ17 assembles at Hvalfjord, Iceland, June 1942. PQ17 was ordered to scatter as the Admiralty feared an attack by the German battleship Tirpitz. The merchant ships were attacked by U-boats and aircraft, and only 11 out of 34 reached Russia. In all, 153 merchant seamen died. In the background is the Soviet tanker Azerbaijan, whose mainly female crew saved their ship after she was bombed and set on fire.

After Germany invaded the Soviet Union (Russia) on 22 June 1941, the Soviet leader, Stalin, demanded help, and the western Allies provided supplies. The most direct route was by sea, around northern Norway to the Soviet ports of Murmansk and Archangel.
The first convoy sailed in September 1941. The route passed through a narrow funnel between the Arctic ice pack and German bases in Norway, and was very dangerous, especially in winter when the ice came further south. Many of the convoys were attacked by German submarines, aircraft and warships. Convoy PQ17 was almost destroyed.
Conditions were among the worst faced by any Allied sailors. As well as the Germans, they faced extreme cold, gales, and pack ice. The loss rate for ships was higher than any other allied convoy route.
Over four million tons of supplies were delivered to the Russians. As well as tanks and aircraft, these included less sensational but still vital items like trucks, tractors, telephone wire, railway engines and boots.
Although the supplies were valuable, the most important contribution made by the Arctic convoys was political. They proved that the Allies were committed to helping the Soviet Union, whilst deflecting Stalin’s demands for a 'Second Front' (Allied invasion of western Europe) until they were ready. The convoys also tied up a large part of Germany’s dwindling naval and air forces.


Cap tally for HMS Edinburgh owned by Radar Operator Arthur Bailey. In April 1942 HMS Edinburgh was detached from her usual Arctic convoy route to collect a cargo of gold bullion from the Russian port of Murmansk. Edinburgh arrived safely but after setting out to join convoy QP 11 for the return journey, she was hit by torpedoes fired by U-456 and attacked by surface ships. Edinburgh eventually had to be abandoned. There were 42 dead on Edinburgh and among the wounded was Arthur Bailey. He was taken to a military hospital at Murmansk in Russia and spent several months there recuperating. He returned to the UK in December 1943.

Seamen clearing ice from the forecastle of HMS Belfast in November 1943. Ice formed from frozen spray would build up on every exposed part of a ship. It had to be cleared regularly or the extra weight could make the ship capsize.

A 50-foot (15m) high wave towers above the bridge of the cruiser HMS Sheffield. During this Arctic gale the wind reached speeds of 65 knots (120kph). Visibility was less than 180m. The heavy seas stripped the armoured roof off one of the ship’s turrets.

Blindfolded survivors from the German battlecruiser Scharnhorst come ashore at Scapa Flow, in Orkney, 2 January 1944.Scharnhorstwas sunk attacking an Arctic convoy on 26 December 1943. Survivors only lasted a few minutes in the icy water, so just 36 of her crew of nearly 2,000 lived. The Battle of North Cape marked the end of the German threat to the Arctic convoys.
