After the Piennes' wedding, the Constable claimed his "right of the lord," also known as "right of the first night," which was believed to be a feudal lord's legal privilege in me-dieval Europe, to have sexual relationships with vassal wom-en, especially on their wedding night. After losing a battle for his king, the man became drunk and angry. He brutally raped her with severe trauma. Lady Joan of Piennes nee Bouvier was a twenty-one-year-old beau-ty. She was repeatedly subjected to sexual assault shortly af-ter losing her virginity, brutally beaten until dawn, and thrown outside the castle like garbage. The Lord of Piennes, Antoine d'Halluin, created in 1520, stood outside the opulent mansion waiting for her. He took her to the wet nurse's residence after getting over his initial shock, but he never stopped grieving. The wet nurse looked after her pregnancy until the day her daughter was delivered when she passed away. The people of the town and everybody else were unaware that she was the Constable's daughter, the two sons' half-sister.
