Final answer:
Hitler abandoned plans to invade the UK after the RAF successfully defended against the Luftwaffe during the Battle of Britain in 1940. His attention shifted eastward, and he launched Operation Barbarossa against the Soviet Union in June 1941, signaling the end of his invasion ambitions toward the UK.
Step-by-step explanation:
When Hitler Abandoned Plans to Invade the UK
After the defeat of France, Adolf Hitler planned to invade the UK to consolidate his control over Europe. This period was marked by the infamous Battle of Britain, which lasted from July through September of 1940. Yet, despite intense aerial combat, the British Royal Air Force (RAF) valiantly defended the skies. Owing to the RAF's resilience and the strategic use of radar, Hitler's goal of achieving air superiority was thwarted. It was the bombing of London and civilian targets that inadvertently allowed Britain to rebuild its defenses. As a result of these setbacks and the failure to destroy the RAF, Hitler gave up his plans for a naval invasion of the British Isles.
Hitler's attention was diverted to Eastern Europe as the RAF began to succeed in aerial battles. The final turning point occurred when Hitler initiated Operation Barbarossa, the invasion of the Soviet Union, in June of 1941. The massive military operation marked the end of Hitler's ambitions to invade Britain; from then on, his focus shifted to the Eastern Front.
