Working as an apprentice clerk at the clothing shop, Jourdan endured for about a year in Lyon before enlisting in the Royal army in 1778,[7] joining the regiment of Auxerrois stationed in the Île de Ré, which was destined for service in the American War of Independence.A few months later the Auxerrois regiment was put under the command of the Comte d'Estaing,[3] and in this assignment Jourdan soon participated in the ill-fated assault at the Siege of Savannah, in October 1779.[9] In June 1784, Jourdan was demobilized from the Royal army in Verdun,[9] and, after a period of unemployment, returned to his native Limoges and found work at a cloth merchant's shop, where he proved to be an excellent employee.Jourdan's first assignment was to relieve General Jacques Ferrand's 20,000-man garrison of Maubeuge which was besieged by an Austrian-Dutch army commanded by Prince Josias of Saxe-Coburg-Saalfeld.Carnot presented Jourdan's arrest warrant, which was signed by Maximilien de Robespierre, Bertrand Barère, and Jean-Marie Collot d'Herbois.Jourdan was saved from certain execution when an eyewitness, representative on mission Ernest Joseph Duquesnoy rose and contradicted Carnot's version of events at Wattignies.[15] Military strategist B. H. Liddell Hart cited Jourdan's maneuver as an example of the indirect approach, even though it was probably inadvertent on the French general's part.[17] During the battle, the Allied attacks pushed back both French flanks, but Jourdan stubbornly fought it out and was saved when General François Joseph Lefebvre's division held its ground in the center.The whole of the French forces were ordered to advance on Vienna, Jourdan on the extreme left, General Jean Victor Marie Moreau in the centre by the Danube valley, and Napoleon on the right in Italy.When war was renewed in 1799, Jourdan was at the head of the army on the Rhine, but again suffered defeat at the hands of Archduke Charles at the battles of Ostrach and Stockach in late March.He remained in the newly created Kingdom of Italy until 1806, when Joseph Bonaparte, whom his brother made King of Naples that year, selected Jourdan as his military adviser.[22] After the disastrous French defeat at the Battle of Salamanca in July 1812, Joseph and Jourdan were forced to abandon Madrid and retreat to Valencia.Repeatedly outmaneuvering the French, the Anglo-Allied army forced Joseph and Jourdan to fight at the Battle of Vitoria on 21 June 1813, during which his marshal's baton was captured by the British.
