Battle of Britain
The Battle of Britain was an air battle which took place between the fall of France in May 1940 and the cancellation of Operation Sea Lion (the planned invasion of Britain) in October 1940.
 
The British won the battle through a combination of superior tactics, the advantage of fighting on home-ground, greater aircraft production and of course, the bravery and skill of the RAF servicemen and women themselves. If the Battle of Britain had been won by the Germans, it is commonly perceived that they would have successfully invaded and occupied Britain, and causing Churchill to say after the battle that 'Never in the field of Human Conflict had so much been owed by so many to so few'.
