Hitler launched the Blitzkrieg, a rapid, massive assault that quickly subdued the nations he invaded. After the fall of Poland, Hitler continued to apply this successful strategy, seizing control of more of Europe’s northern and western nations, including France. When seeking to add Britain to his growing empire, Hitler first launched the Blitz, a series of surprise nighttime bombing raids. The point of the strategy was to destroy the nation’s air force, but it was the British pilots who were responsible for ending the Blitz and preventing the invasion of Britain.
