The Hotel des Invalides founded by Louis XIV.
In 1875 the Invalides numbered 642, and the hOtel cost the state 1,123,053 francs.
Even in its last phase, the Order did not forget its original purpose: it maintained several great hospitals in its new home on the south-east shore of the Baltic, in addition to an hotel des invalides at Marienburg for its sick or aged brethren.
His remains were solemnly removed to the Invalides in 1889.
He returned to France in 1847, and after the rise of Louis Napoleon to power, became successively governor of the Invalides, marshal of France and president of the senate.
In 1849 he became aide-de-camp to Prince Jerome Bonaparte, ex-king of Westphalia, then governor of the Invalides, on whose commission he wrote Memoires pour servir a l'histoire de la campagne de 1812 en Russie (1852).
Whether he finally survived that combat, and spent the remainder of his days in some Hotel des Invalides, I do not know; but I thought that his industry would not be worth much thereafter.
