It has long been known that the British army employed members of the Women's Auxiliary Army Corps as codebreakers in France during the First World War - but beyond the fact that they were known as HushWAACs, a reference to the secrecy of their work, details of their service have been sketchy.
Dr Jim Beach of the University of Northampton has pieced together the handful of sources that are available. This gives us a better understanding of the work of these pioneering women and allows us to publish a full list of their names in acknowledgement of their service.

The BEF signals intelligence organisation was also authorised to employ seven WAACs without officer status, presumably in clerical or other support roles. Sadly, it has not been possible to trace these women.
