The following year (1351) Edward III charged her with having crossed the English Channel in contravention of his prohibition. The inquisition, regarding this incident, shows that Margaret unlawfully crossed the Channel and met with a servant of her future husband, Sir Walter de Mauny, who broke his lantern with his foot so she could pass unnoticed and acted as her guardian during her sojourn in France. This incident and the involvement of her future husband's retainer may indicate the real motivation for Margaret seeking a divorce.
