The Battle Britain:

More than 100 Canadians participated in the Battle of Britain, and 23 lost their lives. A Royal Canadian Air Force squadron fought during the Battle; No. 1 (Canadian) Squadron, whose pilots were from both a regular force unit and an auxiliary unit, became operational on August 17, 1940. 

The Battle of Britain is the name given to the Second World War air campaign waged by the German Air Force (Luftwaffe) against the United Kingdom during the summer and autumn of 1940. The Battle of Britain was the first major campaign to be fought entirely by air forces, and was also the largest and most sustained aerial bombing campaign to that date.

The German objective was to gain air superiority over the Royal Air Force (RAF), especially Fighter Command. From July 1940, coastal shipping convoys and shipping centres, such as Portsmouth, were the main targets; one month later, the Luftwaffe shifted its attacks to RAF airfields and infrastructure. As the battle progressed, the Luftwaffe also targeted aircraft factories and ground infrastructure. Eventually the Luftwaffe resorted to attacking areas of political significance and using terror bombing strategy.

By preventing Germany from gaining air superiority, the British forced Hitler to postpone (and eventually cancel) Operation Sea Lion, a planned amphibious and airborne invasion of Britain. However, Germany continued bombing operations on Britain, known as The Blitz. The failure of Germany to achieve its objectives of destroying Britain's air defenses, or forcing Britain to negotiate an armistice or even an outright surrender, is considered its first major defeat and a crucial turning point in the Second World War.
