Bonn in The Hot War
Bonn served as the de facto capital of West Germany. With the outbreak of the ground war phase of World War III in February, 1951, German Chancellor Konrad Adenauer remained in Bonn, but relocated to a bunker. From here, he cabled U.S President Harry Truman, and begged Truman not to use atomic bombs in the western zone. Truman agreed to Adenauer's request.
