In the summer of 1940, as the Nazi war machine marched its way across Europe and set its sights on Britain, the RAF braced for the worst. 

Young men, in their late teens or early twenties, were trained to fly Spitfires and Hurricanes for the coming Battle for Britain, with others flying Blenheims, Beaufighters and Defiants, becoming the ‘aces’ who would secure the country’s freedom from Hitler’s grasp. 

But Britain’s defiance came at a cost. From an estimated crew of 3,000 pilots, roughly half survived the four-month battle, with 544 Fighter Command pilots and crew among the dead, more than 700 from Bomber Command and almost 300 from Coastal Command falling to secure Britain’s skies. 

The losses were heavy, but the Germans, who thought they could eradicate the RAF in a matter of weeks, lost more. 

2,500 Luftwaffe aircrew were killed in the battle, forcing German Air Command to reconsider how easily Britain would fall to an invading Nazi occupation force. 

The pilots who gave everything in the aerial fight for British freedom were named ‘The Few’, after a speech from Sir Winston Churchill, who said: ‘The gratitude of every home in our island, in our Empire, and indeed throughout the world, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the world war by their prowess and by their devotion.

After the fall of France to the Axis in May 1940, German High Command considered how best to push the fight across the English Channel to take Britain out of the fight.

Up until mid-July the German campaign consisted of relatively small-scale day and night air raids, targeting towns, aerodromes, ports and the aircraft industry.

But the Luftwaffe was at full readiness, ready to ramp up attacks on ships and ports and eliminate the RAF in the air and on the ground.

After the Allies were defeated in western mainland Europe, the German Air Force set up bases near the Channel to more readily take on Britain, hurriedly establishing the infrastructure needed to co-ordinate an aerial conflict with the UK.

As the Battle of Britain begun, the Royal Air Force consistently downed more Axis aircraft than they lost, but British fighters were often overwhelmed by the greater number of enemy aircraft.

Fighting in France and Norway had left British squadrons weakened as the time now came to defend the homeland from Nazi occupation, but as the year went on, the RAF’s fighting force increased in strength, with more pilots, aircraft and operational squadrons being made available.

The Luftwaffe started a mounting campaign of daylight bombing raids, targeting strategic targets such as shipping convoys, ports, and airfields – and probing inland to force RAF squadrons to engage in an attempt to exhaust them.

German air units also stepped up night raids across the West, Midlands and East Coast, targeting the aircraft industry with the objective of weakening Britain’s Home Defence system, especially that of Fighter Command, in order to prepare for a full-scale aerial assault in August.

Heavy losses were sustained on both sides.

The main Luftwaffe assault against the RAF, named ‘Adler Tag’ (Eagle Day), was postponed from August 10 to three days later due to poor weather.

The Germans’ plan was to make RAF Fighter Command abandon south east  England within four days and defeat British aerial forces completely in four weeks.

The Luftwaffe battled ruthlessly in an attempt to exhaust Fighter Command through ceaseless attacks on ground installations, which were moved further inland, with airfields in southern England facing intensive daylight raids while night attacks targeted ports, shipping targets and the aircraft industry.

But despite sustaining heavy damage across the south, Fighter Command continued to push back against the Germans in a series of air battles, which inflicted critical losses upon the enemy, who thought the RAF would have been exhausted by this point.

Both sides feared becoming exhausted through the constant engagements.

Focus of the German attacks then shifted to London, where the RAF would lose 248 and the Luftwaffe would lose 322 between August 26 and September 6.

By September London had become the primary target of Luftwaffe aggression, with large-scale round-the-clock attacks carried out by large bomber formations with fighter escorts.

German Air Command had still not exhausted the RAF as it had hoped to, and British forces continued to face off against their German counterparts, with Fighter Command pushing back Hitler’s forces, forcing German invasion plans to be postponed.

By October, it had become apparent to the Germans that the RAF was still very much intact, and the Luftwaffe struck against Britain with single-engined modified fighter-bombers, which were hard to catch upon entry and still dangerous on their way out.

By the middle of the month German strategy had pivoted from exhausting the RAF to a ruthless bombing campaign targeting the Government, civilian population and the war economy – with London still the primary target.

But as of November, London became less of a target, with the Battle of Britain morphing into a new conflict – the Blitz.
