The Escape from Saint-Martin
The escape plan nobody ever carried out
📱 1 to 10 phones · 1 team per phone · Independent codes
Saint-Martin-de-Ré was the last stop before the penal colonies. Thousands of convicts awaited their transfer to French Guiana or New Caledonia. A legendary escape plan was devised — but never carried out. Vauban's fortifications still guard the secret.
Last stop before hell — and an escape plan never attempted
Between 1873 and 1938, over 70,000 convicts passed through the citadel of Saint-Martin-de-Ré before being shipped to the penal colonies of Cayenne or New Caledonia. Chained in pairs, they walked through the town under the gaze of the inhabitants before boarding the "chicken cages" that took them to the end of the world. Legend has it that a group of convicts devised a perfect escape plan using the flaws in Vauban's fortifications — but were transferred before they could execute it.

« "You don't escape from Saint-Martin. You escape in your mind — and leave the plan for the next one." »— — Legend of the convicts of Île de Ré
Saint-Martin-de-Ré — the gateway to hell
Saint-Martin-de-Ré is a town fortified by Vauban in the late 17th century. Its citadel, a UNESCO World Heritage Site, is a masterpiece of military architecture with its star-shaped bastions, half-moons, and floodable moats. But from 1873, it took on a sinister function: it became the central holding depot for convicts sentenced to hard labor.
The "convict convoy" was a regular spectacle in Saint-Martin. Convicts, chained in pairs, walked through the town streets from the citadel to the port, under the insults or compassion of the inhabitants. They then boarded penitentiary ships — the "chicken cages" — for a journey of several weeks to Cayenne or Nouméa. Many never returned.
Vauban's fortifications, designed to prevent maritime invasions, were turned against their own occupants. But Vauban, a genius of construction, had also left weak points — blind spots, water conduits, service passages. Legend has it that a former military engineer, convicted of forgery, identified these flaws and devised a perfect escape plan. He was transferred to Cayenne before he could execute it, but the plan survived — carved into the stone of his cell.
