The U.S. Allied Commission for Austria (USACA) Section was responsible for civil affairs and military government administration in the American section (U.S. Zone) of occupied Austria, including the U.S. sector of Vienna. USACA Section constituted the U.S. Element of the Allied Commission for Austria. The four-power occupation administration was established by a U.S., British, French, and Soviet agreement signed July 4, 1945. It was organized concurrently with the establishment of Headquarters, United States Forces Austria (HQ USFA) on July 5, 1945, as a component of the U.S. Forces, European Theater (USFET). The single position of USFA Commanding General and U.S. High Commissioner for Austria was held by Gen. Mark Clark from July 5, 1945, to May 16, 1947, and by Lt. Gen. Geoffrey Keyes from May 17, 1947, to September 19, 1950. USACA Section was abolished following transfer of the U.S. occupation government from military to civilian authority. This was marked by President Harry Truman’s appointment of Walter J. Donnelly as Envoy (later Ambassador) to Austria and U.S. High Commissioner for Austria on September 20, 1950. Ambassador Llewelyn E. Thompson, Jr., succeeded Donnelly on July 17, 1952. The U.S. occupation government in Austria officially terminated on July 27, 1955, as a result of the State Treaty for the Reestablishment of an Independent and Democratic Austria, signed May 15, 1955.
The Reparations, Deliveries, and Restitutions (RD&R) Division of USACA Section was organized into branches. Initially, the Property Control Branch and the Monuments and Fine Arts Branch shared the division’s work. However, by February 1946, the work of the Monuments and Fine Arts Branch was substantially completed, and it was disbanded. A new branch called the Reparations and Restitutions Branch was activated at that time to handle general restitution matters as well as any subsequent work related to monuments and fine arts. One additional branch called the German External Assets Branch was organized on October 12, 1946.
The organizational structure and policies used by the division were based largely on similar work performed by the Office of the Military Government, United States Zone (Germany)(OMGUS). The general posture of USACA policy in Austria, however, was intended to achieve a balance between the complete control exhibited by OMGUS and the cooperative atmosphere in the formerly occupied countries of northwest Europe.
The German External Assets Branch investigated and analyzed German business enterprises in the U.S. Zone of Austria in order to determine their appropriateness for reparations, internal restitution, or other disposition. The branch also coordinated efforts with the rest of USACA, making recommendations for the sale or reorganization of German assets.
