An invasion of Britain would then be only possible if the Germans defeated Britain’s air power through bombing.

But the victory of the RAF (The Royal Air Force of Britain) ended this possibility for Hitler and paved the way for his eventual defeat.

Leningrad’s entire population was able-bodied and got mobilized to build fortifications around the city. Leningrad’s defenses stabilized soon, but from November it was almost encircled with its supplies cut off.

This blockade created by the Germans led to the death of 650,000 Leningraders, mostly from starvation and shooting from German artillery. Spare food and medical supplies came in with great difficulty. However, by 1943, the Soviet army ruptured the German blockade and allowed supplies to reach Leningrad. In January 1944, the Soviets drove the Germans out from their city, ending the siege.
