Francis Charles Albert Cammaerts, DSO, code named Roger, was an agent of the United Kingdom's clandestine Special Operations Executive (SOE) during World War II. The purpose of SOE was to conduct espionage, sabotage and reconnaissance in occupied Europe and Asia against the Axis powers, especially Nazi Germany. In France, SOE agents allied themselves with French Resistance groups and supplied them with weapons and equipment parachuted in from England. Cammaerts was the creator and the organiser (leader) of the Jockey network in southeastern France in 1943 and 1944.

Maria Krystyna Janina Skarbek,, also known as Christine Granville, was a Polish agent of the British Special Operations Executive (SOE) during the Second World War. She became celebrated for her daring exploits in intelligence and irregular-warfare missions in Nazi-occupied Poland and France. Journalist Alistair Horne, who described himself in 2012 as one of the few people still alive who had known Skarbek, called her the "bravest of the brave." Spymaster Vera Atkins of the SOE described Skarbek as "very brave, very attractive, but a loner and a law unto herself."
