On June 26, 1948, Allied pilots began delivering supplies to West Berlin after the city was cut off by a Soviet Union blockade. Stalin was trying to forces the Allies to evacuate their section of Berlin. Many thought President Truman should strike militarily, but Truman feared another war. He opted for an airlift of food, clothing, water, medicine and fuel. Soon 2500 tons of supplies were going in to Berlin daily. The Soviets finally lifted the blackade in May of 1949.
