François Bureau, known as "Franchik", was born on April 23, 1921. He regularly stayed in the family fiefdom at the Château de la Meilleraie, in Riaillé. After studying in Nantes, he was admitted to the Saint-Cyr officers' school in 1943. During this period, he was, like so many other men, affected by the STO (Compulsory Work Service), but he decided to leave the country rather than work in Germany, in order to join "the fighting France". Handed over to the Germans with comrades by the smuggler, he was arrested on July 18, 1943, in Perpignan. Then began the transfers from camp to concentration camp: Büchenwald, Laura, Ellrich, Nordhausen. He was part of a medical convoy of more than 1,600 patients. Many died during and after the transfer. He was one of the few survivors. It is at Nordhausen, his last camp, that we can follow his trail. The camp was liberated on April 12, 1945 by the Americans. Death papers mention his death on April 21, 1945, before his repatriation, nine days after the liberation of the camp. François Bureau was therefore free on the day of his death, after more than eighteen months of deportation in Germany. https://www.ouest-france.fr/pays-de-la-loire/ancenis-saint-gereon-44150/francois-bureau-etait-un-homme-de-conviction-4390446

July 25, 1944, shortly after 3 p.m., a Mosquito type plane, a light and fast twin-engine, appeared in the sky of Riaillé, followed a few seconds later by two German fighter planes. Arriving above the hamlet of l'Enclose, one of the fighters gained altitude and dove on the Canadian plane, riddling it with bullets. After starting a curve, the burning Mosquito crashed very close to the Provostière pond. The debris littered the ground for about fifty meters, the fire and the explosion of the ammunition made it impossible to approach. When the fire died down, the inhabitants rushed to the scene and found the charred bodies of the pilot and the navigator. They were identified as Lieutenants Burgess and McPherson. The Germans, who came to the scene, told the mayor that he could bury the bodies but without an official ceremony. However, the occupier's orders were not respected. The bodies were wrapped in sheets and transported to a nearby farm, the village carpentry made the coffins. The next day, a religious ceremony was held in the parish church in the presence of many Riaillé residents and wreaths of flowers covered the coffins. The procession then headed to the cemetery under the supervision of German soldiers who did not intervene. For 80 years, these two Canadian officers have been resting in the Riaillé cemetery. Their tomb is regularly maintained and decorated with flowers by the UNC-Riaillé Mémoire association but also by anonymous people who thus perpetuate the memory of their sacrifice. https://www.echoancenis.fr/actualite-4422-riaille-le-25-juillet-1944-deux-aviateurs-canadiens-etaient-abattus-dans-le-ciel-de-riaille

The wash house is located on the banks of the Erdre, at the exit of the town of Riaillé towards Ancenis. This beautiful building was abandoned for a long time before being restored in 1990-1991. This stone building would have been built around 1850, it measures 20 meters long and 6 meters wide. Today, the site of the wash house is a pleasant place, equipped for picnics as well as a footbridge spanning the Erdre to lead to the Riante Vallée room. https://www.riaille.fr/decouvre/sites-remarquables-et-sentiers-de-randonnee/sites-remarquables-de-la-commune
