After completing her training and being accepted as an agent by the French Section of the Special Operations Executive (SOE) on the night of 5/6 April 1944 Lilian Rolfe was dropped by parachute onto remote farmland near Orléans in north-central France to be the wireless operator for the Historian network supporting the Maquis (French Resistance). Apart from reporting German troop movements, arranging and organising arms and supplies to be dropped by parachute she also worked alongside the Maquis and is known to have been involved in a firefight in the town of Olivet south of Orleans.

Shortly after D-day her circuit leader, George Wilkinson, was captured by German troops and Rolfe continued sending messages to London to support the Maquis but was later captured by the Gestapo whilst transmitting from a safe house in Nargis. Although she was repeatedly tortured for information her wireless was not ‘played back’ to London by a German operator which means she refused to reveal her codes and in August 1944 Rolfe was deported to Ravensbrück Concentration camp in northern Germany. During an investigation after the war it was discovered Rolfe was so ill she was unable to walk (later reports state this was due to leg injuries sustained during torture) and on 5 February 1945, 30-year-old Lilian Rolfe was executed and her body disposed of in the camp crematorium.
