Answer:
Operation Sea Lion
Step-by-step explanation:
Hitler created a plan called Operation Sea Lion to invade the United Kingdom. See, Germany planned to do its amphibious invasion under the cover of darkness. The Royal Air Force's best bombers relied on sights that only worked with plenty of light. At night, Britain's best bombers would be next to useless.
So in 1940, despite Britain's pseudo-alliance with the U.S. and its massive industrial base, Germany had the machinery and troops for an invasion, and Britain lacked the equipment to properly defend itself. And Germany had big plans.
First, the invasion flotilla would launch from bases on the French coast, most likely in September 1940. A diversionary attack would sail north and attack around Newcastle in England or Aberdeen in Scotland, drawing defenders north. Within a few days, the real invasion would come across the Strait of Dover.
Germany's 600,000 troops take the beaches and push through the under-supplied defenders south of London. They only needed to cross 47 miles of England to begin encircling the capital.So Germany had the forces, the plan, and the follow-up, all staged and ready to go right as Britain was at its weakest. So why didn't it happen? Why didn't America have to join the war in Europe with no convenient staging place off of France? With Britain's colonies split between opposition to Germany and loyalty to Edward VIII?
Well, the reasons are many. One was that Hitler was already eyeing an invasion of the Soviet Union and wanted to set aside resources for it. He and Stalin had a non-aggression pact, but Hitler didn't trust him to keep the oil flowing. Another problem was that the German military leaders were fighting among themselves over strategy and roles in the invasion.
But, stupidly enough, part of it was some comments Hitler had made during the initial planning for Operation Sealion.
