Left alone for years at the beginning of the 19th Century, French soldiers taken captive during the Napoleonic Wars found an unusually hobby — fashioning ornate replicas of British ships, out of beef and human bone.
French prisoners of war obtained bones from the food rations issued to them by their English captors. After gathering bones for use in model building, prisoners boiled the bones and bleached them in the sun, to make the bones easier to shape and carve. Pigs around the POW camp also helped to supplement the prisoners’ bone supply [as they] often uncovered human skeletons that were buried in shallow graves.
Many of these artists built mechanisms into their models [which] allowed for the sails of the models to be raised with ease and retract the cannons into the ship.
In addition to human, cattle, and mutton bones, prisoners made use of their own hair to fashion sail rigging, and tissue paper to create sails. On several occasions, visitors to the camp from nearby villagers and British officers would smuggle in pieces of turtle shell, silk, tools, and metal foil for the Frenchmen to use.
British Naval Officers clamored for the opportunity to buy the largest and finest models.
The prisoners’ ship-carving habits did not bother British officials [who] felt the hobby kept the prisoners happy and busy [and] boosted morale. British officers commonly organized civilian markets within the camps — bizarre craft fairs set in the middle of an actual POW camp where the captured soldiers sold their items.
