Charles Nicolas Fabvier

Fabvier then managed to join the diplomatic mission of General Charles Mathieu Gardanne, Napoleon's envoy to Persia, who tried to combat British and Russian influence in the region.

Fabvier was tasked with creating an artillery school and arsenal at Esfahān, and was awarded the newly constituted Order of the Lion and the Sun for his efforts.

He distinguished himself further during the operations of the War of the Sixth Coalition in Germany, and was raised to colonel of the General Staff and made baron de l'Empire.

In 1817, he accompanied Marshal Marmont as chief of staff in quelling the riots at Lyon, provoked by the harsh conduct of the local military governor, General Simon Canuel.

Returning again to Greece, he was appointed head of the small Greek regular army, with which he participated in several battles, most notably the Siege of the Acropolis of Athens in 1826.

Initially chief of staff to General Étienne Maurice Gérard, on 4 August Fabvier was named military commander of Paris.
