[5] Reynier participated in Napoleon's conquest of Malta and the following Egyptian campaign in 1798,[6] commanding a division at the Battle of the Pyramids and, in 1799, at the sieges of El Arish and Acre.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.[11] This impressive array of cannon helped stop a dangerous flanking attack by Johann von Klenau's Austrian VI Armeekorps.Reynier was released after being exchanged for the Austrian general Maximilian von Merveldt, also captured at Leipzig, and arrived in Paris on 15 February 1814.[1] His name is inscribed in column 24 on the southern pillar of the Arc de Triomphe as REYNIER, right above that of fellow Vaudois volunteer Laharpe.
