Hitler released the "Sea Lion Project" and the British air combat began.

The brothers on the second floor are not kidding. 1 Lou is basically right. After France surrendered, the British worried that the truly powerful French fleet would be used by Germany to make the French fleet surrender to the British fleet. The French didn't listen. The French fleet must be defeated.

In the Battle of Britain, it is true that if the Germans continue to attack the British fighter units for two weeks, the British will lose the air superiority in the Strait and the British Isles. The air supremacy is gone, and the powerful British fleet will not last long under the bombing of the German Air Force. But the night attack of British bombers on Berlin disrupted Germany's plans. They had to bomb London in order to appease the morale of the people and the army. The British fighter forces got a break.

The 1 layer has various errors. The British air battle is at 1940. 1943 In March, the first British jet fighter "Thunderbolt" (later renamed Meteor) successfully made a test flight.
