How to Search HS 9 by Agent Name

Clarification on ‘HS 9’ and SOE Records

In the context of researching the Special Operations Executive (SOE), there is no documented archival series, filing system, or operational protocol designated as “HS 9” used for searching agents by name. Researchers seeking information on SOE agents typically engage with the National Archives (TNA) in the United Kingdom, specifically within the HS series of records.

The HS Series at The National Archives

The HS series at The National Archives is the primary repository for SOE records. These files contain a vast array of documents, including personnel files, operational reports, and administrative correspondence. However, the series is organized by function and subject rather than a simple “HS 9” search tool for agent names. To find an agent, researchers generally use the TNA’s online catalogue (Discovery) to search for specific names, codenames, or circuit designations across the various HS sub-series.

Distinction from Modern HS Codes

It is important to distinguish historical SOE archival references from modern terminology. Current digital search results for “HS codes” refer to the Harmonized System, a standardized numerical method of classifying traded products used by customs authorities worldwide [1, 4]. These codes are used to determine tariffs, duties, and taxes for international shipping and have no connection to the wartime activities of the Special Operations Executive [1, 2].

Guidance for Searching SOE Agents

For those attempting to locate an agent’s record within the actual SOE archives, the following steps are recommended:

• Search by Name: Use the National Archives’ catalogue to search for the agent’s legal name.
• Search by Codename: Many agents are only listed under their wartime aliases or codenames.
• Circuit Research: If the agent’s name is unknown, searching for the specific resistance network or circuit (e.g., the Prosper network) often leads to the personnel files of the agents involved.
• Cross-Referencing: Because SOE records were often purged or remained classified for decades, cross-referencing with the Imperial War Museums or local resistance archives in the country of operation is often necessary.
