By 1948, it became apparent that the Western Powers (Great Britain, France, and US) plan to rebuild Germany differed from the Soviet Union's plan. Currency, German Unification, Soviet War reparations, and mere ideology were among the many differences the two sides had. There would be no compromise. As a result, Stalin wanted them out of Berlin. In early 1948, tensions between the once former Allies climaxed. On April 9, 1948, Stalin ordered all American Military personnel maintaining communications equipment out of the Eastern Zone (Soviet controlled Berlin). Trains were halted on June 1 and June 10. On June 21, the Soviets halted a US Military Supply Train and refused it passage to Berlin. On the 22nd, they placed armed guards aboard, attached a Soviet engine and hauled it back to Western Germany. In a final move to spurn the Americans, British, and French out, on June 24, 1948, all land and water access to West Berlin was cut off by the Soviets. There were to be no more supplies from the West. What was going to happen? Where were the necessary supplies going to come from for the Occupation Forces? For that matter, where were the supplies for the 2,008,943 Berliners going to come from? It was a grave situation.
When the blockade began, the Soviets rejoiced, because they believed the Western powers had only one option, to leave Berlin. But they underestimated the West airlift supplies. Gen. Clay called upon General Curtis E. LeMay, commander of USAFE and asked him if he could haul supplies to Berlin. LeMay responded, "We can haul anything". Two days later Gen. LeMay called upon Brig. Gen. Joseph Smith, Commander of the Wiesbaden Military Post, and appointed him Task Force Commander of an airlift operation estimated to last a few weeks. The only US aircraft initially available were 102 C-47's and 2 C-54 Skymasters. On June 26, the first C-47's landed at Tempelhof Airfield, foreshadowing the great operation that was to come. Smith dubbed the mission "Operation Vittles", because he said "We're haulin' grub." The British called their part "Operation Plane Fare".
