When the Decree of Exile of the Nobles was published in 1794 she took refuge at her parents' estate at Moulineaux near Paris. She took in the son of her sister, the Countess of Hinnisdal, who had been guillotined. She took charge and developed the estate. The Reign of Terror ended with the death of Maximilien Robespierre on 28 July 1794. Sister Camille applied for permission to return to Paris, which was granted on 15 October 1794. She rented a house on Rue des Postes near the seminary church. The following year, she rented a larger house on the Rue Saint-Jacques where she set up a small improvised convent that became home to many nuns coming out of prison, and also accommodated several ecclesiastics who were passing or in distress. A decree published in 1796 authorized nobles who had not fled France during the revolution and the Terror to recover their property. Camille de Soyécourt was the heiress of her family, but hesitated to take steps that seemed contrary to her vow of poverty. Pope Pius VI urged her to demand the return of family property and even made it a duty to preserve it. The pope authorized her to do so by a brief of July 1797. The situation was surprising enough at the time for some to speak jokingly of the "Carmelite millions". On 8 August 1797 Mother Camille de l'Enfant-Jésus redeemed some of the buildings of the Carmes convent in the Rue Vaugirard. This saved the building from destruction. She launched major works to restore the buildings, which had been badly damaged and had no doors or windows, with rubble everywhere. Later her hagiographers would say that the bloodstains of the victims of the Carmes Prison were still visible on the walls. The church and some residential buildings were the first targets of the works. On 24 August 1797 the first mass was celebrated in the chapel of St. Joseph. On 29 August 1797 the convent's church could be used again and was officially blessed by the Bishop of Saint-Papoul in a rich ceremony. She also had a "chapel of martyrs" built and restored in memory of the massacre of 2 September 1792 that took place in the former prison. The nuns even collected some vestiges that they kept as relics. A dozen Carmelites settled in the improvised convent. Mother Camille chose for her cell the room which had served as a prison for her father a few years earlier.
