efore the Battle of Britain, no country had succeeded in stopping the Nazi army. The Germans sped through France in two weeks and looked across the English Channel expecting an easy victory. The Germans did not anticipate the superiority of British air power and its successful new radar technology, nor the interception of the German code device Enigma. These advantages and the British resolve held the Germans back despite the constant bombings on London, civilian targets, and military sites. By October, Hitler called off Operation “Sea Lion,” and the planned invasion of England was thwarted. The British won a small victory by holding out and staying strong.
