SOE Personnel Files: Medical Reports, Training Reports, and Appraisals

Overview of the Personnel Files (PF Series)

The Special Operations Executive (SOE) maintained a rigorous system of record-keeping for its personnel to ensure that agents were physically, mentally, and professionally equipped for the extreme dangers of clandestine warfare. These records are primarily preserved in the Personnel Files (PF Series), catalogued under the reference HS 9 at The National Archives in the United Kingdom [1, 3].

The PF Series serves as a comprehensive administrative trail for SOE agents and staff active between 1939 and 1946 [3, 4]. Because the nature of clandestine work varied wildly—from wireless operation to sabotage and political liaison—the contents of individual files vary considerably [1]. While some files are exhaustive, others may contain only a brief note indicating that an individual was considered for service but not ultimately recruited [3].

Medical Reports and Physical Suitability

Given the high physical demands of parachuting, long-distance trekking, and the potential for capture and torture, medical screening was a prerequisite for SOE service. The personnel files often contain detailed medical reports [1]. These documents were used to assess an agent’s resilience and ensure they could withstand the rigors of field operations without becoming a liability to their network or mission.

Training Reports and Performance Appraisals

Training was the cornerstone of SOE’s operational security. Before deployment, agents underwent intensive courses in tradecraft, sabotage, and linguistics. The PF Series captures the results of this process through:

• Appraisals of Performance: Evaluators recorded how well a recruit mastered specific skills, such as the use of clandestine radios or the placement of explosives [1].
• Suitability Assessments: Beyond technical skill, SOE psychologists and instructors assessed an individual’s temperament and suitability for particular roles [1]. This included evaluating their ability to maintain a cover identity under pressure and their capacity for independent decision-making in hostile environments.
• Activity Reports: For those who successfully deployed, files may include reports of their activities in the field, providing a retrospective look at how their training translated into operational success or failure [1].

Administrative Contents and Identification

Beyond medical and training data, the personnel files functioned as the primary administrative record for the individual. Many files include passport-style photographs of the subject, which provided a visual record of the agent’s appearance before they adopted their wartime aliases [1]. These files are often organized by name, with specific references (such as HS 9/1/1 for Harald Konrad Aaberg) allowing researchers to track individual service histories [4].

Archival Research and Interpretation

For historians and family researchers, the PF Series is an invaluable resource, but it requires careful interpretation. Because the files were created for internal administrative and security purposes, they often contain candid, sometimes harsh, assessments of an agent’s personality or failings. Researchers must distinguish between a recruit’s potential as seen by an instructor and their actual performance in the field.

The records are held within the broader Records of Special Operations Executive (HS) collection [3]. When searching these archives, it is important to note that not every person associated with the SOE will have a full file; some may only appear in the records of the specific country section or network they served within.
