Cause

Following Britain's rejection of peace overtures, Hitler issued Directive No. 16 on 16 July 1940 ordering preparations for the invasion of Britain (Operation Sea Lion). Air superiority over the RAF was deemed essential before any landing could proceed, prompting Directive No. 17 on 1 August ordering the Luftwaffe to destroy RAF Fighter Command.

Event

On 13 August 1940, the Luftwaffe launched Adlertag, the opening day of Operation Eagle Attack. Despite inflicting ground casualties and material damage, the operation was hampered by poor intelligence and communication failures, and the German air attacks did not significantly degrade Fighter Command's capacity to defend British airspace.

Consequence

Göring's promise that Adlerangriff would neutralize the RAF within days or weeks went unfulfilled. The Luftwaffe failed to destroy RAF Fighter Command or achieve the local air superiority required for an amphibious invasion, forcing the indefinite postponement of Operation Sea Lion and marking a strategic setback for Nazi Germany.
