FLEURY Jean, Désiré Born June 18, 1910, in Paris (12th arrondissement) DE STOPPELEIRE Louis, Ernest Born December 28, 1922 in Paris (XIVth arrondissement), hanged by SS on August 25, 1944 in Bois-Guilbert (Seine-Inférieure, Maritime); maquisards of the group "Les Diables Noirs"; Maquis de Ry (Seine-Inférieure, Maritime). On August 25, 1944, while Jean Fleury was arriving through the woods in the village of Bois-Guilbert (Seine-Inférieure, Maritime) armed with a rifle, accompanied by Louis De Stoppeleire, also armed, they encountered SS who were stationed in the village . They asked for their papers and hung them on a separate tree in the forest. Starting from the center of Bois-Guilbert in the direction of Héronchelles is on the edge of the forest (a) monument built in memory of two young armed men who were surprised and captured there by an SS battalion ... They were, at the statements by municipal witnesses of the time, forced to dig their graves before being hung with fence wire and then shot dead. Before the maquis, Jean Fleury lived with his wife in Seine-Inférieure, in Mont-Saint-Aignan, at 71 Chemin de Clère. This explains the presence of his name as shot on the war memorial of this city near Rouen, next to Jean Bourgeois and Robert Lehman. The Black Devils network to which the victims belonged had been created by the brothers Henri and Raoul Boulanger within the sawmill they owned in Saint-Denis-le-Thiboult. A clever underground hiding place sheltered resistance fighters. Arrested by the Gestapo on March 14, 1944, the two brothers who revealed nothing decisive under torture, allowed the Black Devils to continue their action, despite new arrests and deportations, until the total liberation of the Seine-Inférieure around August 30, 1944.

this porch is one of the most finely and richly decorated in the region, even in France. It is a true work of art whose ornaments bear witness to the social, military and religious history of the Renaissance.

The Saint-Sulpice church in Ry underwent several developments from the 12th to the 19th century. These successive embellishments testify to the importance of the village, which had no less than 600 inhabitants in the 13th century. The most remarkable arrangement is undoubtedly the 16th century carved oak porch, listed MH and inspired by the Italian Renaissance. It forms an ensemble richly decorated with biblical figures, plant elements and imaginary or warlike animal representations. An overturned boat hull vault, characteristic of Norman architecture, covers it. Remarkably well preserved, this porch is one of the most finely and richly decorated in the region, if not in France. Beyond its primary function of shelter, this porch is a true work of art, the ornaments of which bear witness to the social, military and religious history of the Renaissance.
