Madeleine Zoe Damerment (11 November 1917 – 13 September 1944) was a French agent of the United Kingdom's clandestine Special Operations Executive (SOE) organization during World War II.

The purpose of SOE was to conduct espionage, sabotage, and reconnaissance in countries occupied by the Axis powers, especially Nazi Germany.

Damerment was to be a courier for SOE's Bricklayer circuit but was captured by the Gestapo on 29 February 1944 upon arrival in France.

Damerment became engaged to Roland Lepers, a young man who guided escaping Allied airmen and French soldiers from Lille to Marseille, where the Pat Line was headquartered.

Avoiding arrest, Damerment crossed the border illegally into Spain, reaching Barcelona along with Lepers on 10 March 1942.

Spain was attempting to quell the influx of people fleeing the German occupation of most of Europe and Damerment was arrested on 24 April and incarcerated until 30 May, when the British Embassy secured her release.

Sent to Scotland for paramilitary training, Captain Dixon-Robertson, her signals instructor at Inverie (STS 24), determined that, only being considered fair for sending and receiving messages, she was unsuitable for work as a wireless operator.

However, Captain Smith reported that, for physical training, Damerment was a "keen and hard worker with good stamina."

[6] For weapons training, Damerment was reported to have improved and was "now a fair shot with pistol and carbine, but is lacking in aggressiveness.

Since June 1943, SOE headquarters in London had indications that the Prosper and other networks had been penetrated by the Germans, their radios compromised, and many of their operatives captured.

Damerment was assigned as courier with the Bricklayer network, and she and agents France Antelme, an experienced leader and organiser, and Lionel Lee (wireless operator) parachuted from a RAF special duties 161 Squadron Halifax into a field near the city of Chartres on the night of 29 February 1944.

[10][11] Agents of the Sicherheitsdienst (SD), the intelligence agency of the SS in Paris headed by Major Josef Kieffer were waiting on the ground for them.

[12][15][16] A Gestapo man named Max Wassmer was in charge of prisoner transports at Karlsruhe and accompanied the women to Dachau.

[17] Another Gestapo man named Christian Ott gave a statement to American investigators after the war as to the fate of Damerment and her three companions.

[18] Ott was stationed at Karlsruhe and volunteered to accompany the four women to Dachau as he wanted to visit his family in Stuttgart on the return journey.

The four prisoners now had to kneel with their heads towards a small mound of earth and were killed by the two SS, one after another by a shot through the back of the neck.

"[20] Damerment's colleagues France Antelme and Lionel Lee were also executed while captives of the Germans Following the war, Damerment's contribution was recognised by her government with the posthumous awarding of the Legion of Honor, Croix de Guerre, the Médaille de la Résistance, and by the British King's Commendation for Brave Conduct.

[21] There is also a plaque on the south wall of the crematorium at the former Dachau concentration camp, where the four SOE agents are remembered.
