1948 the Russians decided they had had enough of the small island of capitalist imperialism that was West Berlin. It seethed with the spies of enemy countries. It was a toehold for the Allies on socialist soil. In a modern siege, Stalin’s forces cut off the land supply routes through East Germany to West Berlin. On the night of 24 June 1948, they switched off the eastern power plant that supplied the city. The West Berliners were to be starved out in the dark.
