Eugène began his military career in the War in the Vendée, serving under General Lazare Hoche, and fought at Quiberon. However, within a year his mother Joséphine had arranged his return to Paris. In the Italian campaigns of 1796–1797, Eugène served as aide-de-camp to his stepfather, whom he also accompanied to Egypt. In Egypt, Eugène was wounded during the Siege of Acre (1799) and returned to France with Napoleon in the autumn of 1799, helping to bring about the reconciliation of the General and his mother, who had become estranged due to the extramarital affairs of both. During the Coup of Brumaire, Eugène accompanied Napoleon to Saint-Cloud, where the legislative assemblies were brought into submission.
