Of
an easy family, Pérignon undertakes a military career
which it gives up rather quickly. Appointed in 1791, it re-enlists
the following year to fight the invasion of Coalisés.
With the Army of Pyrenees-Eastern, it becomes major general.
In 1793, it is in charge of the command as a head of all the
army. It demolishes the Spaniards with Escola. In 1795, it takes
the town of Rosas. Appointed with the Council of Cinq-Cents under
the Directory, it is named ambassador in Spain, with the mission
of concluding an alliance offensive-defensive. It will be the
treaty of San-Idelfonse, in August 1796.

Then
Pérignon is mingled with a business with smuggling and
compromise with a young spy. The Directory recalls it in 1798
and names it with the Army of Italy. Arrived in May, it is wounded
and captured one month later, with the battle of Novi. Of return
in France, he becomes military head of division in Toulouse,
in 1801. He is also a senator and it is for this reason that
Napoleon appoints it marshal in 1804. Two years later, it entrusts
the government of Parma to him. Named then in Naples, Pérignon,
recently annobli, is one of familiar of the royal couple Murat
and Caroline. Re-entered to France in 1814, it joins in Louis
XVIII who raises his title of count to that of marquis.
