How did Truman eventually managed to break the Berlin Blockade?

President Harry S. Truman managed to break the Berlin Blockade through the implementation of the Berlin Airlift, which began in June 1948. When the Soviet Union blocked all ground access to West Berlin, Truman authorized a massive airlift operation to supply the city with essential goods, including food and fuel. Over the course of nearly a year, Allied forces flew in over 2.3 million tons of supplies, demonstrating commitment to West Berlin and effectively circumventing the blockade. Ultimately, the Soviet Union lifted the blockade in May 1949, realizing that their strategy had failed.
