How the Soviet's react to the blockade
The Berlin Airlift. Please note that Britain and France also had their sectors in Berlin and played an important part in the Airlift.
After Germany surrendered it was decided that Berlin, located entirely in East Germany, would be occupied by four Allied powers. The USSR administered the eastern part of the city, and the US, Great Britain, and France administered the western part. This arrangement quickly broke down and the USSR tried to force the Western Allies out by closing the land routes to Berlin. The city was then supplied entirely by air (The Berlin Airlift) for a time until the Soviets agreed to reopen the roads. To prevent East Germans from fleeing to the West, the Berlin Wall was built in 1961, and it divided the city until 1989.
