In early September 1944, Aimée Corge, a 22-year-old French woman, was driven to RAF Harrington, an airfield near Kettering, Northamptonshire. At 2115 pm an American B-24 Liberator took off and in the early hours of the next morning she parachuted with a wireless set onto a plateau in the Vosges Mountains of Northeast France. Who was Aimée Corge? What was her background? What was she doing in Britain? Why was she parachuted into France? What did she need a wireless set for? What happened to her? Intelligence historian Bernard O'Connor has investigated her story using recently declassified documents from the National Archives in Kew. Most of the above questions he has been able to answer but, given the TOP SECRET nature of her mission, not all.
