[5] On 24 November 1805, his 2nd Division helped capture Louis Victor Meriadec de Rohan's 4,400 Austrians at the Battle of Castelfranco Veneto.

[9] 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.

On 4 July of that year, an Anglo-Sicilian force inflicted a severe defeat 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.

Leading the Saxon corps plus an attached French division, Reynier fought at the battles of Kalish, Bautzen, Grossbeeren and Dennewitz in 1813.

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.
