Battle of Britain
The Battle of Britain was an intense air battle between the Germans and British over Great Britain's airspace from July 1940 to May 1941.
Germany expected to conquer their last western enemy easily with domination over airspace and then later sending ground troops across the English Channel. They started in July of 1940. They first targeted airfields, but switched to bombing strategic targets, wanting to crush British morale. However, the morale stayed and high and the reprieve given to british airfields gave the British Air Force (or RAF) the break they needed. Even though Germany continued to bomb Great Britain for months, it was clear by October the British had won, forcing the Germans to wait on their invasion. It was the Germans first defeat in WW2.
