After their arrest in Paris, Philippe Égalité and his son, the comte de Beaujolais, were imprisoned in the Abbey prison ("prison de l'Abbaye") in Paris. Later, the two were transferred to the prison of Fort Saint-Jean in Marseille, where they were soon joined by the duc de Montpensier who had been arrested while serving as an officer in the Army of the Alps. The day before his father and brothers were arrested in France, the duc de Chartres rushed to Tournai, near the French border, where his sister Adélaïde and Mme de Genlis had been living since Philippe Égalité had made them emigrate in November 1792.
