In the summer and fall of 1940, German and British air forces clashed in the skies over the United Kingdom, locked in the largest sustained bombing campaign to that date. A significant turning point of World War II, the Battle of Britain ended when Germany’s Luftwaffe failed to gain air superiority over the Royal Air Force despite months of targeting Britain’s air bases, military posts and, ultimately, its civilian population. Britain’s decisive victory saved the country from a ground invasion and possible occupation by German forces while proving that air power alone could be used to win a major battle.
On June 17, 1940, the defeated French signed an armistice and quit World War II. Britain now stood alone against the power of Germany’s military forces, which had conquered most of Western Europe in less than two months. But Prime Minister Winston Churchill rallied his stubborn people and outmaneuvered those politicians who wanted to negotiate with Adolf Hitler. But Britain’s success in continuing the war would very much depend on the RAF Fighter Command’s ability to thwart the Luftwaffe’s efforts to gain air superiority. This then would be the first all-air battle in history.
