For decades, they were dismissed as mere vandalism—modern graffiti clinging to the ancient stone of one of southern France’s most iconic landmarks. However, a recent investigation has revealed that several inscriptions on the Aqueduc des Arceaux in Montpellier are not random tags, but clandestine messages left by the French Resistance during the height of the Second World War.
The discovery of these 1942 tags in Montpellier marks a rare locate in the study of clandestine communication. Formally attributed to the “Combat” network, one of the most influential Resistance movements of the era, the markings serve as a physical ghost of the “Zone Libre,” the unoccupied region of France where the fight against Nazi collaboration and German occupation was waged in the shadows.
The identification process began when two lawyers from the Montpellier bar, Isabelle Durand and Cédric Amourette, were alerted by a colleague. The colleague had shared a family memory linked to the markings, prompting the legal duo to move beyond the assumption that the paint was contemporary. What followed was a meticulous forensic and archival search that transformed a piece of urban blight into a protected historical artifact.
Decoding “Combat châtie les traîtres”
The centerpiece of the discovery is a slogan painted high upon one of the aqueduct’s pillars: “Combat châtie les traîtres” (Combat punishes the traitors). This phrase was not merely a spontaneous act of defiance but part of a coordinated psychological warfare campaign. By placing the message in a high-visibility area, the Resistance aimed to intimidate collaborators and signal to the oppressed population that an organized force was watching.
To authenticate the tag, Durand and Amourette collaborated with local institutions, including the Musée de la Résistance and the departmental archives of Hérault. The verification relied on three critical pillars of evidence:
- Photographic Analysis: High-resolution imaging confirmed the age and placement of the paint, which had remained visible due to the technical difficulty of removing it from the high stone surfaces.
- Archival Cross-Referencing: Researchers located period leaflets and pamphlets that utilized the same rhetoric and slogans.
- Historical Testimony: The writings of Henri Frenay, the founder of the Combat network, explicitly mention a systematic campaign of graffiti conducted across several cities in the unoccupied zone, including Montpellier.
Beyond the primary slogan, investigators have identified two additional inscriptions in the vicinity. While one remains only partially legible, the cluster suggests that the Arceaux served as a strategic point for the network’s propaganda efforts in 1942.
The Strategic Role of the Combat Network
The Combat network was not just a paramilitary organization; it was a sophisticated intelligence and propaganda machine. Founded by Henri Frenay, it sought to unify various resistance cells and provide a political voice to the struggle. In cities like Montpellier, the employ of “tags” was a calculated risk. In an era of strict censorship and the constant threat of the Milice (the Vichy French paramilitary force), painting a wall was an act of extreme courage.
The choice of the Aqueduc des Arceaux as a canvas was likely intentional. As a prominent architectural feature of the city, it ensured that the message reached a wide cross-section of the public, from local residents to German patrols. The height of the inscriptions further suggests a level of planning, requiring the agents to scale the structure under the cover of darkness to avoid detection.
| Stage | Action | Key Contributors |

| Initial Trigger | Family memory of inscriptions shared by a lawyer | Montpellier Bar members |
| Investigation | Field analysis and photographic documentation | Isabelle Durand & Cédric Amourette |
| Verification | Consultation of Henri Frenay’s writings and leaflets | Hérault Departmental Archives |
| Authentication | Formal attribution to the Combat network (1942) | Musée de la Résistance |
Preserving a “Forgotten” Heritage
The transition of these markings from “tags” to “heritage” highlights a recurring challenge in urban archaeology: the invisibility of history. For decades, the inscriptions were seen as a nuisance to be cleaned or ignored. Now, they are viewed as a rare tangible link to the internal resistance of 1942.
The discoverers are now calling for the formal protection of these markings. The goal is to integrate the graffiti into the local “parcours mémoriel” (memorial trail), ensuring that future generations understand the context of the struggle. Because the paint has survived the elements and various cleaning attempts over eighty years, there is a pressing need for conservation efforts to prevent further degradation.
This discovery underscores the importance of local archives and the role of citizen-led research in uncovering hidden histories. By linking a personal family memory to official state archives, the investigation has successfully mapped a specific moment of defiance in Montpellier’s wartime history.
The next phase of the project involves a formal request to local heritage authorities to designate the site as a protected historical marker. This would prevent any future restoration work from inadvertently erasing the 1942 messages. Further research is expected to continue in the Hérault archives to determine if other similar “Combat” tags exist in the region.
