OSS

OSS — Office of Strategic Services — was the United States intelligence organisation operational from June 1942 through the post-war dissolution ordered by President Truman in September 1945 and effective 1 October 1945. The OSS was substantially the institutional ancestor of the Central Intelligence Agency and the broader US post-1947 intelligence-community architecture. The director throughout its operational existence was William J. Donovan ("Wild Bill" Donovan), the New York lawyer and World War I Medal of Honor recipient whose institutional advocacy for an integrated US foreign-intelligence capability had begun with the July 1941 establishment of the Office of the Coordinator of Information (COI), the OSS's immediate predecessor.

The OSS's operational responsibilities were broader than those of any single subsequent US intelligence agency. The organisation conducted HUMINT collection in occupied Europe, North Africa, the Middle East, and Asia; paramilitary operations through its Special Operations and Operational Groups branches in support of partisan resistance movements; counterintelligence work through its X-2 branch (the OSS component through which the organisation obtained access to Ultra signals-intelligence product from the British, under the compartmentation arrangement the British required as a condition of OSS access); analytical work through its Research and Analysis (R&A) branch — the institutional centre, under William Langer and subsequently Sherman Kent, of what became the post-war strategic-intelligence analytical tradition; psychological and political-warfare operations through its Morale Operations branch; and a substantial operational training and infrastructure mission. The organisational scale at its 1944–45 peak was approximately 13,000 personnel.

The OSS's principal documented operational achievements in the war include the substantial HUMINT collection from neutral capitals (the Bern station under Allen Dulles being the most documented, producing the Operation Sunrise negotiations with German SS officers in northern Italy in early 1945 and substantial reporting on the German internal political situation through the Fritz Kolbe agent); the Operational Groups' work with French, Italian, Yugoslav, and Greek partisan movements; the R&A branch's substantial economic and political-analytical product on the German and Japanese war economies (the institutional template for the post-war national intelligence estimates); and the organisation's operational integration with British SOE and SIS, which was the principal vehicle through which the post-war US-UK intelligence cooperation framework was institutionally established.

The OSS's institutional liquidation effective 1 October 1945 and the subsequent twenty-three-month interregnum before the establishment of the Central Intelligence Agency in September 1947 has been the subject of substantial subsequent institutional analysis. The post-war debate about whether the United States should retain a peacetime foreign-intelligence capability — and if so, whether that capability should reside in the State Department, the War Department, the Navy Department, or in a new independent agency — was conducted through 1945–46 in a sequence of executive-branch studies (the October 1945 Eberstadt Report on unification of the armed services, the November 1945 Lovett Report on postwar intelligence organisation, and Admiral Souers's June 1946 final report as outgoing director of the Central Intelligence Group) that produced the National Security Act of 1947 and the institutional architecture under which the CIA, the DCI position, the National Security Council, and the Department of Defense were established. The CIA inherited substantial portions of the OSS R&A branch's analytical personnel, the OSS X-2 counterintelligence branch's institutional culture, and (through the parallel post-war Strategic Services Unit established under the War Department to hold the OSS operational personnel during the interregnum) the OSS HUMINT and counterintelligence operational tradition; the paramilitary tradition was reconstituted separately inside the post-1947 CIA.

The OSS's institutional myth has been substantial. The organisational record has been the subject of sustained popular and academic literature — the published memoirs of OSS veterans, the substantial subsequent academic histories (Anthony Cave Brown, Bradley Smith, Joseph Persico, Thomas Powers, Douglas Waller, R. Harris Smith), and the museum and exhibition record — that has produced an institutional ancestor-myth around which the modern CIA's institutional identity has been substantially constructed. The myth has been an institutional resource and an institutional liability in roughly equal measure: the operational tradition the OSS established was substantially less successful than the popular institutional memory suggests, and the post-1947 CIA's institutional record has at points been distorted by an overly close identification with the OSS operational culture.
