In 1792 Dedon-Duclos joined the Army of the Center and he took command of the 5th Foot Artillery. In the following months he served at the combat before Landau, at the action of Spire, at the action of Mainz, and then before Frankfurt. In 1793 Dedon-Duclos was named directory of artillery at Mainz and that June he was promoted to chef de battalion by the representatives of the people. That July he served under General de Beauharnais at the combats near Landau and then he took command of the artillery during the Siege of Landau.

In 1806 Dedon-Duclos was named director general of the artillery parks of the Army of Naples and he served at the Siege of Gaeta as commander of the artillery.

The next month Dedon-Duclos definitively returned to the service of France as a général de brigade and he was placed in charge of the bridging teams of the Grande Armée. He next served at the defense of Mainz until the city was surrendered after Napoleon's abdication in 1814.
