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.

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.

Montevideo at that time had about one million people, and more than half of those were watching the scene…the sun was setting, a beautiful day, clear skies, a perfect stage for the end of a drama.

Victory in the Battle of the River Plate, the first major naval engagement of the war, was a great boost to British morale during the ‘Phoney War’.
When war broke out, the German pocket battleship Graf Spee, commanded by Captain Hans Langsdorff, was patrolling in the Atlantic. She represented a grave threat to Allied shipping, sinking six merchant ships between September and December.
Seven Allied ‘hunting groups', totalling 23 major warships, were sent to look for her. After sinking three more ships, Langsdorff made for the busy shipping lanes off the River Plate. Commodore Henry Harwood of Hunting Group G correctly guessed Langsdorff’s intentions, and on 13 December he closed in with the heavy cruiser HMS Exeter and light cruisers HMS Ajax and HMS Achilles.
Langsdorff concentrated his fire on the heavier Exeter, setting her alight, destroying most of her guns and forcing her to leave for the Falkland Islands. Shifting fire to Ajax, Langsdorff disabled two of her four turrets before breaking away for the port of Montevideo, in neutral Uruguay. Harwood kept watch outside while other Allied ships rushed to the area.
According to international law, a warship could only remain in a neutral port for 24 hours, and British diplomats tried to have Graf Spee interned or forced to leave. Langsdorff extended his stay by 72 hours but finally had to leave on 17 December. Only the cruiser HMS Cumberland had arrived to reinforce Harwood, but Langsdorff, convinced that strong forces were waiting, sank Graf Spee himself rather than risk another battle.
