ÉDOUARD-ADOLPHE-CASIMIR-JOSEPH, Duke of Treviso and Marshal of France, was born at Château-Cambresis in 1768. At the age of twenty-three he entered the army of the Revolution as captain in a battalion of volunteers. He fought with distinction at the battles of Jemeppe and Neerwinden, and was gradually promoted. In 1799 the rank of general of brigade had been conferred upon him. Serving soon afterwards as a general of division in the army of Switzerland, he led the right wing of Massena's forces in the battle of Zurich. His next important service was the occupation of the electorate of Hanover in 1803. On his return in the following year, his valour was publicly acknowledged by Bonaparte; and a marshal's baton and the rank of general of the consular guard were conferred upon him. He supported his reputation at the battle of Friedland in 1807. The title of Duke of Treviso was bestowed upon him in 1808. At the head of the 5th corps in the army of Spain he defeated the Spaniards at Ocaña in 1809, and at Jebora in 1811. He served under Napoleon in the Russian expedition, and at all the important battles of 1813 and 1814. In this latter year the defence of Paris against the victorious allies was entrusted to him and Marshal Marmont. He was one of those who sent in their allegiance to Louis XVIII. at the commencement of the Hundred Days, recalled it when Napoleon landed from Elba, and renewed it after the battle of Waterloo. Yet his attachment to the Bourbons did not prevent him, after the Revolution of 1830, from rising into favour with Louis Philippe. He was riding by the side of that monarch at a review of the National Guard of Paris, on the 28th July 1835, when the infernal machine of Fieschi, intended for the destruction of royalty, exploded. Marshal Mortier was among the number of those who were struck dead on the spot.
