The failure of "Adlertag" did not deter the "Luftwaffe" from continuing its campaign. The assault against RAF airfields continued throughout August and into September 1940. The battles involved large numbers of aircraft and heavy losses on both sides. The "Luftwaffe" failed to develop any focused strategy for defeating RAF Fighter Command. At first, it attempted to destroy RAF bases, then switched to strategic bombing by day and night. It tried to achieve the destruction of several British industries at the same time, switching from bombing aircraft factories, to attacking supporting industries, import or distribution networks such as coastal ports. An attempt was even made against unrelated targets, such as destroying the morale of the British population.
