Marguerite de Thibouville’s alleged rape on January 18, 1386, became the defining accusation in the case against Jacques Le Gris and ultimately helped bring about the judicial duel between Le Gris and Jean de Carrouges. The event was not preserved through a surviving transcript of Marguerite’s spoken testimony: its details are known principally through a court summary, later legal notes, and competing accounts whose uncertainties endured long after the proceedings ended.

Circumstances and Stakes

The alleged assault took place at Château de Capomesnil while Jean de Carrouges was away on business in Paris. In the account Marguerite later gave under oath, she identified Jacques Le Gris and Adam Louvel as the two men involved. She said she saw them in daylight, that Louvel named Le Gris before Le Gris appeared a few minutes later, and that she spoke with both before the attack. The case records preserve this as her accusation, not as an independently witnessed account of what happened inside the castle.

The accusation carried exceptional personal risk in a society that prized a noble wife’s chastity as a guarantee of legitimate inheritance. Jean was substantially older than Marguerite, and the marriage was expected to produce legitimate heirs; the prevailing double standard demanded strict sexual fidelity from wives even as noblemen took liberties elsewhere. Her family history heightened the danger of public disgrace: her father, Robert de Thibouville, had twice betrayed the kings of France, leaving the family under suspicion. The accusation therefore exposed Marguerite not only to scrutiny of her conduct but also to the old stigma attached to her name.

Jacques Le Gris warned Marguerite that disclosure could bring further shame and that her husband might kill her rather than believe her. The threat drew force from the risks the account describes: Jean was jealous and suspicious, and husbands could sometimes escape punishment for killing wives they accused of adultery. Le Gris knew Jean from their long acquaintance at the court of Argentan and may have been exploiting both the husband’s temperament and Marguerite’s vulnerability. The narrative presents that calculation as a possibility, not an established motive.

Disclosure and Testimony

Marguerite did not tell her mother-in-law, who had returned from a brief journey to Saint-Pierre-sur-Dives on the day of the attack. She remained silent until Jean returned from Paris, probably on January 21 or 22. In the meantime, she committed the day and time of Le Gris’s visit to memory, preparing for the questions she expected from her family and for the public ordeal that might follow. Her silence thus lasted only a few days; it did not become the permanent submission Le Gris’s warning appears to have sought.

When the Parlement of Paris opened its inquiry, Marguerite was its chief witness. Although women could not bring criminal charges on their own, the official record states that information was received through her deposition or oath, and that court officers questioned and examined her closely and repeatedly. A remark in Le Gris’s testimony indicates that she appeared before the king and the assembled Parlement near the beginning of the inquiry before being questioned privately. By mid-July she was already six months pregnant, making that public appearance more difficult; as the case continued into late summer, she was at least eight months pregnant and faced the strain of waiting in unfamiliar surroundings.

The knight, the squire, and Marguerite gave their testimony in Norman French, but no transcript of their spoken evidence survives. A professional scribe rendered the case into Latin in a detailed summary of nearly ten folio-sized pages, setting out Jean’s charges, based on his wife’s sworn account, alongside Le Gris’s lengthy defense. That surviving document records the proceedings through the language of the court rather than preserving Marguerite’s own words verbatim.

From Inquiry to Judicial Duel

The accusation entered a system in which proof was difficult and the parties did not meet on equal ground. Le Gris was a favorite of Count Pierre of Alençon and was well regarded at the royal court in Paris. As a cleric in minor orders, he could also claim benefit of clergy and seek transfer to a church court. Marguerite, by contrast, was the wife of one of Count Pierre’s troublesome vassals and the daughter of a man already marked by treason. These conditions made the prospect of a straightforward hearing uncertain even before the evidence was weighed.

Jean’s appeal turned the accusation into a prolonged public legal contest. After the inquiry, the Parlement authorized a judicial duel between Jean de Carrouges and Jacques Le Gris at Saint-Martin’s dueling ground. The combat was meant to resolve the charge through a result that the legal culture treated as judgment, although the procedure could not recover direct proof of the alleged assault. Its formal equality was carefully staged: because Jean was a knight and Le Gris only a squire, Le Gris was knighted before the fight. Their actual circumstances remained unequal in other respects, including experience, strength, wealth, equipment, and health.

The duel’s rules reveal how far the dispute had moved from testimony to bodily contest. It was no tournament: once combat began, the fighters could use any means to defeat one another, without the restraints associated with chivalric sport. The outcome was supposed to settle guilt, but it could not make the underlying event directly observable. The accusation thus passed from Marguerite’s sworn account, through a written inquiry, into a public trial by combat whose verdict depended on what happened between two armed men.

Uncertainty and Afterlife

Marguerite’s testimony remained firm during the proceedings. In his diary, Jean Le Coq, Le Gris’s lawyer, counted against his client the fact that Carrouges’s wife never relented in affirming that the deed had occurred. Le Coq also recorded arguments for Le Gris, including knights’ claims that they had seen him with Count Pierre throughout the day. He noted the suggestion that Le Gris might have refused to confess because of the scandal confession would cause among his sons and friends, particularly after Count Pierre had declared him innocent. Yet the lawyer’s final assessment acknowledged the limits of what even a close observer could know: no one really knew the truth of the matter.

The uncertainty continued into later historical memory. Jean Froissart, writing within a few years of the duel, said that the king, court, and crowd rejoiced at its outcome; Le Coq recorded divided reactions, with some seeing Jean vindicated and others believing Le Gris unjustly killed. The Saint-Denis Chronicle later claimed that Marguerite had accused Le Gris mistakenly but in good faith and that another felon eventually confessed. A version of that story persisted in later chronicles and became a legend of false accusation, wrongful death, and delayed revelation.

The book challenges that legend without claiming that the record can settle every question. Marguerite’s identification of two alleged attackers, including her account that Louvel named Le Gris before he appeared, makes mistaken identity less plausible in the author’s assessment; naming Louvel also complicated the theory that she deliberately fabricated the accusation, since adding another alleged participant increased the burden of proof. Nevertheless, later writers repeatedly recast the affair as a miscarriage of justice. In the eighteenth century, Enlightenment commentators used the story to condemn judicial combat, and the accusation’s long afterlife became inseparable from the unresolved question it had first put before the court.
