The first great sorrow was the death of Mme. de la Fayette on Christmas Eve, 1808, at the age of forty-eight. Her health had been completely undermined by the terrible experiences of her imprisonments; and an illness caused by blood-poisoning during her captivity with her husband in Austria, where she was not allowed proper medical attendance, was the climax from which she never really recovered. She died as she had lived, like a saint, at La Grange, surrounded by her broken-hearted husband and family, and by her own request was buried at Picpus, where, chiefly by the exertions of the three sisters, a church had been built close to the now consecrated ground where lay buried their mother, sister, grandmother, with many other victims of the Terror.

The wanderings and perils of Pauline were now at an end. From henceforth her home was with her husband and four children in the old château of Fontenay, which they repaired and put in order. It was a fortress built in the reign of Charles VI., and afterwards inhabited and decorated by the Duc d’Epernon. The great tower of the castle still bore his name, and the blue and gold ceiling of his bedroom still remained. It had an immense park and lakes, and a great avenue of chestnut-trees led up to the château. The Abbé Cartier, curé of Fontenay, was a man after her own heart. He had known her mother, for he came very young to the parish, which he loved with all his heart, and which he had only once left, on the approach of a revolutionary mob. Leaving the presbytère with all his own things at their mercy, he hid the cross and all the properties of the church, and as to the statues of the saints which he could not remove, he painted them all over, turning them into National Guards with swords by their sides. He was only persuaded by his people to escape when already the drums of the approaching ruffians were heard in the village, in which they quickly appeared, and rushed into the church. But they found it empty, except for the statues, with which, in their republican garb, they dared not meddle, so they turned their fury upon the presbytère, and when the good Abbé returned he found the church uninjured, but all the contents of his house stolen or destroyed. As far as possible, M. and Mme. de Montagu led the simple patriarchal life they preferred at Fontenay, where they were adored by the people, to whom they devoted their time, money, and attention. Under the trees before the castle stone benches were placed for the peasants who came on Sunday evenings to sit about and dance, and the young people with whom the old château was always filled joined eagerly in their festivities.

The harmony and affection that had characterised the daughters of the Duchess d’Ayen were equally conspicuous among her grandchildren, and the numerous relations—sons, daughters, nephews, nieces, and cousins—formed one united family. If there existed differences of opinion, they did not interfere with the affection between those who held them.

The daughter of the Vicomtesse de Noailles was married to the Marquis de Vérac. Of the sons, Alexis, between whom and Pauline there was an especially deep affection, and whose principles entirely agreed, refused to accept any employment under the government of Buonaparte. In consequence of the part he took in favour of the Pope he was imprisoned, and only released by the influence of his brother Alfred, an ardent soldier in the Imperial army, who, after distinguishing himself and winning the favour of the Emperor, was killed in the Russian campaign.

Though her winters were generally spent in Paris, Pauline only went out quietly amongst her own friends, not entering at all into the society of the imperial court, which was altogether objectionable to her.

The Restoration was received with rapture by her and most of her family, not even La Fayette himself holding aloof from the welcome to the King.

Alexis de Noailles, who had left France during the reign of Napoleon, entered Paris with the Comte d’Artois; the King and the Duchesse d’Angoulême received with distinguished favour those who had suffered so much in their cause; the Duc de Noailles came from Switzerland and took possession of the hôtel de Noailles, just vacated by the Arch-treasurer of the Empire.

But as the size and grandeur of such a residence was no longer suitable to the altered fortunes of its master, he sold it, and only occupied the part called the petit hôtel de Noailles, where Mme. de Montagu also had an apartment.

The rest of her life was spent in peace amongst her family, by whom she was adored, in the practices of charity and devotion, which had always made her happiness.

Mme. de Tessé died in 1813, only a week after the death of her husband, without whom she said that she did not think she could live.
