Barthélemy Catherine Joubert (14 April 1769 – 15 August 1799) was a French general. He joined the royal French army in 1784 and rose rapidly in rank during the French Revolutionary Wars. Napoleon Bonaparte recognized his talents and gave him increased responsibilities. Joubert was killed while commanding the French army at the Battle of Novi in 1799.
The son of an advocate, Joubert was born at Pont-de-Vaux (Ain), and ran away from school in 1784 to enlist in the artillery. He was brought back and sent to study law at Lyon and Dijon. In 1791, during the French Revolutionary Wars, he joined the French Revolutionary Army regiment of the Ain, and was elected by his comrades successively corporal and sergeant. In January 1792 he became sous-lieutenant, and in November lieutenant, having in the meantime experienced his first campaign with the army of Italy.
In 1793, Joubert distinguished himself by the defence of a redoubt at the Col de Tende in north-west Italy, with only thirty men against a battalion of the enemy. Wounded and made prisoner in the battle, he was released on parole by Austrian Commander-in-Chief De Vins, soon afterwards. In 1794 he was again actively engaged, and in 1795 promoted to brigadier general.
In the campaign of 1796, Joubert became part of Napoleon Bonaparte's overall command. He led a brigade under Pierre Augereau in the Battle of Millesimo and under André Masséna at the Battle of Lodi. He also fought at the Battle of Castiglione in August. He soon attracted the special attention of Napoleon Bonaparte, who made him a general of division in December 1796, and repeatedly selected him for the command of important detachments. Thus, he led the holding force in the Adige River valley at the Battle of Rivoli. In the spring campaign of 1797 (invasion of Austria) he commanded the detached left wing of Bonaparte's army in the Tyrol with great distinction, fighting his way through the mountains to rejoin his chief in Styria. General Joubert intervened against Tyrolean companies of sharpshooters, with an angry message on February 15, 1797, to crush their resistance: " I declare that I consider as enemies of the French, all the fathers, whose children are enrolled in the Tyrolean companies of sharpshooters, will be imprisoned and their property confiscated for the benefit of the Republic .
