He took part in operations tied to campaigns on fronts involving the Armée du Nord, the Armée des Pyrénées, or the Armée d'Italie where commanders such as Napoleon Bonaparte, Jean-Baptiste Jourdan, and Jean Victor Marie Moreau reshaped French military practice. In the Napoleonic period he held commands compatible with the hierarchy of the First French Empire and interacted with marshals and ministers from the circles of Charles-Maurice de Talleyrand-Périgord, Louis-Alexandre Berthier, and others responsible for organization and logistics.
