of 1809 he was sent to Vienna to arrange the marriage of the Emperor with Archduchess Marie Louise. In 1810 he was subsequently appointed Minister Plenipotentiary in Bavaria at Munich, next to King Maximilian I, whom he knew very well before the Revolution, and in 1811 aide-de-camp to Napoleon. He was created an Officer of the Legion of Honour and Grand Cross of the Order of Saint Hubert. In 1812 he went on diplomatic mission to Prussia; this mission had the purpose of ascertaining King Frederick William III towards his attitude in case France went to war with Russia. In returning to Paris, de Narbonne-Lara advised Napoleon not to invade Russia, but his advice was not followed; and so he reassumed his place in the Imperial Army on the Russian border. When he arrived there, he was sent by Napoleon to the city of Wilna, where the Tsar was; the comte de Narbonne-Lara was the bearer of an ultimatum, to which Alexander I categorically refused. The tragic outcome of the Russian Campaign did not minimize the action of the Officers of the Imperial Army. Among them, he was outstanding for his military uprightness and exemplary behaviour; in the whirl of the retreat, he appeared dauntless and serene, his presence imposed confidence and respect to the demoralized troops. Mounted on his horse beside the carriage of the defeated Napoleon, he was the personification of the dignity and honour of the Ancien Régime. In 1813 he was appointed and sent as French Ambassador at Vienna, where he was engaged in an unequal diplomatic duel with Metternich during the fateful months that witnessed the defection of Austria from the cause of Napoleon to that of the Allies, to confirm the alliance between France and Austria, objective he was not able to fulfill; the Empire had its days cut short. In that same year he was appointed Governor of the stronghold of Torgau (Saxony), one of the main strategic points for the defense of the Empire. On 17 November 1813, after reviewing the troops on horse, he died of typhus. His aide-de-camp, Captain comte de Rohan-Chabot, brought his heart back to France, and afterwards the name of the comte de Narbonne-Lara was inscribed on the east side of the Arc de Triomphe.
