A general of brigade from August 1813,[1] he fought with distinction at Bautzen[2] and played a significant part at the battle of Leipzig, covering the retreat of the army.

Back to France in 1814, Poret de Morvan was entrusted with the mission of creating a "Young Guard" division,[1] then took part to the fighting in Champagne, where he was wounded again.

[1] During the "Hundred Days", Poret de Morvan rallied to Napoleon[1] and was given command of the 3rd Foot Grenadier Guards regiment, two battalions, with a complement of 1,164 officers and men.

Placed in the front line during this epic action, Poret de Morvan and his men were noted for their gallantry but were also exposed to the most murderous fire from enemy artillery and musketry,[4] resulting in losses of 58% for the entire regiment during this battle.

[1] General Poret de Morvan died on February 17, 1834, aged 56[1] and is buried at the Père Lachaise Cemetery in Paris.
