[2] Garnier received promotion to general of division on 20 December 1793[4] and returned to the Army of Italy in April 1794 where he may have fought at the Battle of Saorgio.

The small divisions of Garnier and Francois Macquard defended the Col de Tende and were not in action during the Montenotte Campaign.

After the French success, a messenger arrived from the north ordering Garnier and Macquard to join the rest of the army in Piedmont.

His harsh opinion of Garnier, Jean-Baptiste Meynier, and Raphaël de Casabianca stated, "incapable; not fit to command a battalion in a war as active and serious as this one".

[8] After a period of eclipse, Garnier was employed on the frontier of the Kingdom of the Two Sicilies and was later installed as military governor of Rome.

[2] On 29 September his 4,500-man garrison capitulated to a 4,000-strong Anglo-Neapolitan force commanded by Lieutenant General Emanuele de Bourcard.

Suchet's forces were involved in actions at Monte Settepani, San Giacomo, Loano, and Montecalvo between 10 April and 7 May.

Moving across the unguarded Col de Tende, part of his corps captured 600 Austrians and seven guns at Monte Nave south of Cuneo.

[14] Garnier retired from the army in 1801 but was quickly called back to fill positions in the reserve during the Napoleonic Wars.

[15] After the fall of Emperor Napoleon, King Louis XVIII bestowed letters of nobility on the old republican general on 31 December 1814.
