<P> On September 20, 1945, as part of Truman's dismantling of the World War II war machine, the OSS, at one time numbering almost 13,000, was eliminated over the span of ten days . A reprieve, though, was granted six days later by the Assistant Secretary of War, reducing it to a skeleton crew of roughly 15% of its peak force level, forcing it to close many of its foreign offices; at the same time the name of the service was changed from the OSS to the Strategic Services Unit . </P> <P> During World War II, President Roosevelt was concerned about American covert intelligence capabilities, particularly in the light of the success of Churchill's Commandos . On the suggestion of a senior British intelligence officer, he asked Colonel William "Wild Bill" Donovan to devise a combined intelligence service modeled on the British Secret Intelligence Service (MI6), and Special Operations Executive, centralizing, for instance, the separate cryptanalysis programs of the Army, and Navy . This resulted in the creation of the Office of Strategic Services . On September 20, 1945, shortly after the end of World War II, President Harry S. Truman signed an executive order, to dissolve the OSS by October 1, 1945 . The rapid reorganizations that followed reflected not only routine bureaucratic competition for resources but also exploration of the proper relationships between clandestine intelligence collection and covert action (i.e., paramilitary and psychological operations). In October 1945, the functions of the OSS were split between the Departments of State and War: </P> <Table> <Tr> <Th> New unit </Th> <Th> Oversight </Th> <Th> OSS functions absorbed </Th> </Tr> <Tr> <Td> Strategic Services Unit (SSU) </Td> <Td> War Department </Td> <Td> Secret Intelligence (SI) (i.e., clandestine intelligence collection) and counter-espionage (X-2) </Td> </Tr> <Tr> <Td> Interim Research and Intelligence Service (IRIS) </Td> <Td> State Department </Td> <Td> Research and Analysis Branch (i.e., intelligence analysis) </Td> </Tr> <Tr> <Td> Psychological Warfare Division (PWD) (not uniquely for former OSS) </Td> <Td> War Department, Army General Staff </Td> <Td> Staff officers from Operational Groups, Operation Jedburgh, Morale Operations (black propaganda) </Td> </Tr> </Table> <Tr> <Th> New unit </Th> <Th> Oversight </Th> <Th> OSS functions absorbed </Th> </Tr>
