In summer 1948, the Russians occupied all of Eastern Europe. Behind Russian lines, the Allied-controlled part of the great city of Berlin stood as the lone Western outpost in a sea of Communist occupation. Then the Soviets closed all Allied traffic through their zone, sealing off the food and supply routes on which the city relied. A vast air armada streamed from Western airfields to supply the hard-pressed Berliners with food and necessities. For over a year the Americans led a gigantic,and successful,effort to keep an entire city alive in the face of Soviet hostility. This is a story of individual heroism and high brinkmanship politics, of daily life under appalling circumstances and great achievements against all odds.
