Philippe de Vosjoli and James Angleton: CIA-SDECE Liaison and French Embassy Operation

SUMMARY

Philippe de Vosjoli was a French SDECE (Service de documentation extérieure et de contre-espionnage) agent who served as the SDECE station chief in Washington D.C. from 1951 to 1963. During this period, a relationship developed between de Vosjoli and James Angleton, the head of CIA counterintelligence. A declassified CIA document indicates that this relationship, alongside information from Anatole Golitsen, led Angleton and Dick Helms to approve a counterespionage operation against the French Embassy in Washington, which involved breaking and entering and the removal of classified documents. Claims also suggest de Vosjoli facilitated a liaison between French intelligence and the CIA's counterintelligence branch and hosted figures associated with the OAS (Organisation armée secrète) during the Algerian War period.

STRONGEST CASE FOR

The declassified CIA document (Source [5]) directly indicates a 'developing relationship' between de Vosjoli and Angleton, leading to a sanctioned counterespionage operation against the French Embassy. This primary source corroborates claims of a significant liaison and collaboration, potentially involving sensitive intelligence exchanges and operations. De Vosjoli's high-level position as SDECE station chief in Washington (Source [6]) would have naturally positioned him for such interactions with senior CIA officials like Angleton, especially concerning counterintelligence matters during the Cold War.

STRONGEST CASE AGAINST

While a relationship between de Vosjoli and Angleton is explicitly mentioned in a CIA document, the full nature and extent of 'collaboration' or 'liaison activities' beyond the specific counterespionage operation against the French Embassy are not detailed in the provided sources. The mention of de Vosjoli hosting Jacques Soustelle (Source [3]), an OAS supporter, raises questions about the alignment of de Vosjoli's activities with official French government policy, particularly if the OAS aimed to overthrow de Gaulle. The CIA document focuses on an operation *against* the French Embassy, suggesting a complex, potentially adversarial, dynamic rather than straightforward 'collaboration' in all instances. Further details are needed to understand the broader context of their interactions.
