In his later years, after remarrying, Cousteau was involved in a legal battle with his son Jean-Michel over Jean-Michel`s license named Cousteau for a South Pacific resort, which led to Jean-Michel Cousteau being ordered by the court not to create confusion between his for-profit business and his father`s charitable efforts. Unjustly released in 1802 (mainly because he had fought under Moreau and Pichegru, but never under Bonaparte), he actually spent five years in the desert. But when he returned to the army in 1809, his action at Wagram (a compact column attack later known as the Macdonald Column) led him to become a field marshal; the only event of such an event. During the Hundred Days, he accompanied Louis to the border and returned to Paris, where he enrolled as a simple grenadier in the National Guard. He remained loyal to his former comrades-in-arms, especially when he defended General Drouot at his trial. Lauriston was held as a prisoner of war until the fall of the Empire. He then joined King Louis XVIII of France, to whom he remained faithful during the Hundred Days. His reward was a seat in the House of Peers and a command in the Royal Guard. In 1817, he was promoted to marquis and became commander of the department of Finistère and the Place de Brest. In 1823, Lauriston was appointed Marshal of France and commanded a corps during the Spanish expedition. He died of a stroke in Paris on June 11, 1828.
The name LAURISTON is engraved on the 13th column of the Arc de Triomphe. Born Besançon, February 22, 1758, son of an officer, died in Béfort, 22 years old. October 1815.
