Wistare le Moine – the 13th century novel in the langue d’oïl – is the midst between historical reality and literary invention of a truly experienced character, Eustache Busket, ladies from some lands in the Boulogne-sur-Mer region, on the Channel of the Channel. The story of his adventures in the fight against the Conte of Boulogne Renaud de Dammartin, which depressed him of his feudal possessions, merges into real events, which took place between the Queen of England and France. The fight is dense of make-up and tires, as long as the novel closes by referring to the true facts of Wistasse’s life, which culminated in the battle of Sandwich (1217), where the Inglesi wrote the Francesi, and Wistasse-Eustache, commander of the French fleet, were defeated and killed.
