Jean Louis Ebénézer Reynier (14 January 1771 – 27 February 1814) rose in rank to become a French army general officer during the French Revolutionary Wars. He led a division under Napoleon Bonaparte in the French Campaign in Egypt and Syria. During the Napoleonic Wars he continued to hold important combat commands, eventually leading an army corps during the Peninsular War in 1810-1811 and during the War of the Sixth Coalition in 1812-1813.
Reynier joined the French army as a gunner in 1792 and fought at the Battle of Jemappes that year. He received promotion to general of brigade in January 1795. He was General Jean Moreau's chief-of-staff in 1796 and soon became a general of division. He went on Napoleon's Egyptian expedition in 1798 and commanded a division at the Battle of the Pyramids, the Siege of El Arish and the siege of Acre. Later, under the command of General Jacques-Francois Menou he defended against the British counter-invasion of Egypt in 1801. His division was present but not engaged in the Battle of Alexandria. After returning to France, Reynier killed a fellow general in a duel and was under a cloud for a time.
Reynier fought with the army of Marshal André Masséna in the 1805 Italian theater. On 24 November, his 2nd Division helped capture Prince Louis Victor Rohan-Guéméné's 4,400 Austrians at the Battle of Castelfranco Veneto. Reynier's 6,000 Frenchmen routed the 10,000-man army of the Bourbon Kingdom of Naples and Sicily at the Battle of Campo Tenese on 9 March 1806. This victory helped Napoleon to install his brother Joseph Bonaparte on the throne of the newly created Napoleonic Kingdom of Naples. On 4 July of that year, a British raiding force inflicted a severe drubbing on an overconfident Reynier at the Battle of Maida in southern Italy. Reynier was later able to reassert French control of the area via the French victory at Mileto and served under King Joseph as his Minister of War and Marine.
