charged with protecting the army's lines of communications during the Ulm campaign. He fought in the battles of Konstanz and Bregenz, before tracking down and destroying General Franz Jellacic's Austrian division at Dornbirn in Vorarlberg on 13 November 1805. This was followed by the occupation of Frankfurt am Main. His wife Gabrielle died while he was away. During the War of the Fourth Coalition, Augereau was again commander of the VII Corps. He distinguished himself at the Battle of Jena on 14 October 1806 where his corps made up the left flank. Early in 1807, he fell ill with fever, and at the Battle of Eylau on 7 February 1807, he had to be supported on his horse. Nevertheless, he directed the movements of his corps with his usual bravery. Augereau's corps was almost annihilated and the marshal himself received a wound in the arm from grapeshot. Augereau became Duke of Castiglione on 19 March 1808, a hereditary victory title (i.e. not in chief of an actual fief, but a hollow title), in honour of the 1796 victory. In 1809, he married the 19-year-old Adélaïde Josephine Bourlon de Chavange (1789 – 1869) whom he had become infatuated with. Adélaïde, the daughter of Gilles Bernard Bourlon de Chavange and wife Jeanne Françoise Launuy, had no children with Augereau and the ducal title became extinct upon his death. His wife later remarried Camille de Sainte-Aldegonde (1787 – 1853), by whom she had a daughter Valentine de Sainte-Aldegonde (1820 – 1891), who married the 3rd Duke of Dino. While serving in Catalonia during the Peninsular War from February to May 1810, Augereau gained some successes but tarnished his name with cruelty. During the Russian campaign in 1812, he did not leave Berlin. It was Augereau's brother Jean-Pierre, serving under Louis Baraguey d'Hilliers, who was taken prisoner by the Russian vanguard near Smolensk. He sat out the German campaign in spring 1813 due to illness. Before the Battle of Leipzig in October, Napoleon reproached him with not being the Augereau of Castiglione; to which he replied, "Give me back the old soldiers of Italy, and I will show you that I am." Yet, he led the IX Corps at Leipzig with skill and brought off his command in good order. In 1814, Augereau was given command of the army of Lyon, and his slackness exposed him to the charge of having come to an
