Quote: By late 1944, it was obvious to von Braun that Germany would be defeated and occupied, and he began planning for the postwar era. Before the Allied capture of the V–2 rocket complex, von Braun was sent south, eventually to Bavaria. He surrendered to the Americans in the Austrian Alps, along with other key team leaders. For 15 years after World War II, Von Braun worked with the U.S. Army in the development of guided missiles. As part of a military operation called Project Paperclip, he and an initial group of about 125 were sent to America where they were installed at Fort Bliss, Texas. There they worked on rockets for the U.S. Army and assisted in V-2 launches at White Sands Proving Ground, New Mexico.
