Identification
Operation Overcast — Major Staver's original intent was only to interview the scientists, but what he learned changed the operation's purpose. On 22 May 1945, he transmitted to US Pentagon headquarters Colonel Joel Holmes's telegram urging the evacuation of German scientists, and their families, as most "important for Pacific war" effort. Most of the Osenberg List engineers worked at the Baltic coast German Army Research Center Peenemünde, developing the V-2 rocket; after capturing them, the Allies initially housed them and their families in Landshut, Bavaria, in southern Germany.
Beginning on 19 July 1945, the US Joint Chiefs of Staff (JCS) managed the captured ARC rocketeers under a program called Operation Overcast. However, when the "Camp Overcast" name of the scientists' quarters became locally-known, the program was renamed Operation Paperclip in March 1946. Despite these attempts at secrecy, later that year the press interviewed several of the scientists.
Regarding Operation Alsos, Allied Intelligence described nuclear physicist Werner Heisenberg, the German nuclear energy project principal, as " . . . worth more to us than ten divisions of Germans." In addition to rocketeers and nuclear physicists, the Allies also sought chemists, physicians, and naval weaponeers.
Meanwhile, the Technical Director of the German Army Rocket Center, Wernher von Braun, was jailed at P.O. Box 1142, a secret military-intelligence prison in Fort Hunt, Virginia in the United States. Since the prison was unknown to the international community, its operation by the US was in violation of the Geneva Convention of 1929, which the U.S. had ratified. Although Von Braun's interrogators pressured him, he was not tortured; however in 1944 another PoW, U-boat Captain Werner Henke was shot and killed while climbing the fence at Fort Hunt.
