A famous quote by Sir Winston Churchill on The Battle of Britain.

In July 1940, Great Britain stood alone against Hitler's Nazi Germany. Their long standing allies, namely France, the Netherlands, Belgium, Luxembourg, Denmark, and Norway had been overrun in a short period of months by the German blitzkrieg.

With a standing nonaggression pact between Germany and the Soviet Union (signed in 1939) and a still neutral United States, Great Britain prepared for war against the Nazi warmachine without a single ally.

One advantage Britain had was its separation from the European landmass. The English Channel, a body of water that's roughly 21 miles at its widest, presented a natural defense against the blitzkrieg.

It was clear that if Hitler was to conquer Great Britain, then he had to first win air superiority over the English Channel and England itself so that his troops may cross safely.

Churchill knew this so he and the British government had to prepare for an air war. One that was to become one of the most celebrated in world history.

From July 10 to October 31, 1940, known throughout history as The Battle of Britain, the Royal Air Force (RAF) defended against the overwhelming number of fighters and bombers of the Luftwaffe, the German air force. The RAF pilots flew the Supermarine Spitfires and the Hawker Hurricanes. The Luftwaffe had the Messerschmitt Bf 109. All three fighter aircrafts were considered the most modern fighter airplanes of their times.

In his book, The Second World War (1954), Winston Churchill wrote that "[t]he Germans' [planes] were faster, with a better rate of climb; ours more maneuverable, better armed." Additionally, he assessed the pilots from both sides indicating that the German pilots were more numerous and more experienced from their recent victories. But, the RAF pilots "had supreme confidence in themselves as individuals and that determination which the British race displays in fullest measure when in supreme adversity."

The famous Spitfires typically engaged the German Messerschmitt Bf 109 fighters while the Hurricanes took out the bombers.

The Hurricanes were the great workhorse of the Battle of Britain. Although the Spitfires received notoriety for engaging the Bf 109 fighters, that wasn't always the case. The Hurricanes also had their licks and shouldered most of the fighting.

One of the first true modern fighter planes of its times, the Messerschmitt Bf 109 took to the skies against the Royal Air Force. Fuel injected engines gave the Bf 109 climbing and diving advantages over it's British counterparts.

The Battle of Britain was fought in three successive and, sometimes, overlapping phases:

Phase I: July 10 to August 18, 1940.  The air war took place primarily along coastal England and the English Channel. In this initial period, according to Churchill, the Royal Air Force was going to be "tested, drawn into battle and depleted, and damange done to those seaside towns marked as objectives for the forthcoming invasion."

Phase II: August 24 to September 27, 1940.  The Luftwaffe was to completely destroy the Royal Air Force by bombing key facilities such as air fields and aircraft manufacturing buildings. The defeat of the RAF was crucial to Phase III, which was the bombing of London itself.

Phase III: October 1940 when it was evident that the Luftwaffe was not able to defeat the RAF and gain superiority of the English skies, Hermann Wilhelm Goering, commander of the Luftwaffe, "resigned himself to the indiscriminate bombing of London and the centers of industrial production."

However, Churchill himself noted in his book that the Phase II attacks heavily damaged the air fields and facilities South and Southeast of England which provided the air defense over London. 

It seemed that Goering made a premature switch to Phase III to the thankful praises of the Brits.  Churchill went on to write in his book that "[i]f the enemy had persisted in heavy attacks against the adjacent sectors and damaged their operations rooms or telephone communications, the whole intricate organization of the Fighter Command might have been broken down. It was therefore with a sense of relief that Fighter Command felt the German attack turn onto London on September 7..."

Legendary American journalist and radio reporter Edward R. Murrow was assigned in London at the time when German bombers were conducting night raids to dishearten the British civilians.

In a broadcast on October 10, 1940, he described the day after a bombing:

"All the fires were quickly brought under control. That's a common phrase in the morning communiqués. I've seen how it's done, spent a night with the London fire brigade. For three hours after the night attack got going, I shivered in a sandbag crow's nest atop a tall building near the Thames. It was one of the many fire-observation posts. There was an old gun barrel mounted above a round table marked off like a compass. A stick of incendiaries bounced off rooftops about three miles away. The observer took a sight on a point where the first one fell, swung his gunsight along the line of bombs and took another reading at the end of the line of fire. Then he picked up his telephone and shouted above the half gale that was blowing up there: 'Stick of incendiaries -- between one-ninety and two-twenty -- about three miles away.'

Five minutes later, a German bomber came boring down the river. We could see his exhaust trail like a pale ribbon stretched straight across the sky. Half a mile downstream there were two eruptions and then a third, all close together. The first two looked as though some giant had thrown a huge basket of flaming oranges high in the air. The third was just a balloon of fire enclosed in black smoke above the housetops...", p135, Illustrated Story of World War II, Reader's Digest, Fourth Printing 1978.

The Battle of Britain marked one of the turning point in World War II. Prior to Britain's resistance, Hitler's war machine had gone unchallenged and seemed nigh unstoppable. But the victory was not without it's cost. In his book, Winston Churchill gave the following tally of losses for both sides from July 10 to October 31, 1940:

• Aircraft lost by the Royal Air Force (complete write-off or missing) -- 915
• Enemy aircraft claimed by the RAF -- 2,698
• Enemy aircraft destroyed according to German records -- 1,733
