Special Operations Executive

See also: Clandestine human-source intelligence and covert action

Subordinate to the wartime Ministry of Economic Warfare, the British Special Operations Executive (SOE) was a cadre for guerilla warfare and direct action (military) in occupied Europe. It was commanded by Colonel Colin Gubbins. Winston Churchill had ordered Hugh Dalton, the Minister of Economic Warfare, to "set Europe ablaze."

The core of SOE came from Section D of the Secret Intelligence Service. . It has been the conventional wisdom that this is the basic British doctrine, but, as with so many things in the clandestine and covert worlds, it is not that straightforward. .

WWII wartime & permanent UK

SOE conducted competent training in parachuting, sabotage, irregular warfare, etc. It could check language and marksmanship skills, as well as examining clothing and personal effects for anything that could reveal British manufacture, SOE trained agents in the distinguishing uniforms, insignia, and decorations of the Germans, "But it could not teach them the organization, modus operandi, and psychology of the German intelligence and security services; and it did not call upon the MI-5 and MI-6 experts who did know the subject..." those services also were reluctant to provide SOE with access to their own sensitive sources. While isolating SOE from the clandestine services provided some mutual passive security, it also failed to provide proactive counterintelligence.

Operations

"The consequences of this shortcoming are evident in the German counterintelligence coups in France, Belgium, and Holland...While the Security Service maintained an extensive name index, the Registry (partially destroyed by German bombing, but otherwise irreplaceable), SOE apparently did not maintain a counterintelligence index against which prospective field recruits could be checked. SOE received help from the British police, but not the security experts.

In particular, a large SOE guerilla network, PROSPER, under Major Francis Suttill, was exposed and destroyed by the Germans, due to poor operational security. There have been speculation that PROSPER, however, may have been sacrificed to cover more secret British operations, such as the penetration of the Sicherdienst by Alain Dericourt.

Disposition

"At the end of the war the Foreign Office and the Chiefs of Staff agreed to return the responsibility for covert operations to the jurisdiction of the Secret Intelligence Service. There were three reasons for the change: to ensure that secret intelligence and special operations were the responsibility of a single organization under a single authority; to prevent duplication, wasted effort, crossing of operational wires, friction, and consequent insecurity; and to tailor the size of the covert action staff to the greatly reduced scale of peacetime needs. The peacetime condition also added a new factor which greatly increased the importance of consolidation.
