I admit I'd never heard of this unit of volunteers engaged in the pyrenees in the 1790s. However, I'm interested in tracing one of their officers, Captain Gory (initial J so probably Joseph), who could have been aide-de-camp to Muller or Hoche in 1796 and was a colleague of Matthieu Dumas. Prisoner of War in Litchfield in 1798, captured with Humbert.
Can anyone help?
Yes these units can be very confusing. This is taken from General Jean Marie Vergez's memoirs;
Vergès had therefore improved his general education in an appreciable way and successfully begun his technical training when he returned to Saint-Pé, a few months before the Revolution, his leave having expired. We know nothing about the way in which he employed his time during the years which preceded the declaration of war in 1792, but he must have at that date, like most of the former soldiers who then lived in their homes, been chosen as an instructor in the corps of volunteers organized at all points of the territory, and it was thus that he was appointed captain of the battalion of mountain hunters into which the contingent of Saint-Pé(1) was incorporated.
At this critical time, it was in front of the enemy that the officers had to educate their soldiers. Hardly organized, the battalion of hunters of Argelès was designated to go to join the army known as the Pyrénées-Occidentales, and it is in the valley of Baztan that we find Vergès in 1793, at the head of a frank company known as mountain scouts. We know that this army, commanded by General Muller, whose name history has forgotten, but in which figured men whose fame was soon to grow, Moncey, Harispe, both future Marshals of France, Marbot, La Tour d'Auvergne, Merle, etc., valiantly supported, on this frontier, the fortune of our arms and inflicted on the

Helpful, but inconsistent with the oracle that is Wiki https://fr.wikipedia.org/wiki/Volontaires_nationaux_pendant_la_R%C3%A9volution.
As to your main question - have you looked at Jorge Planas Campos's list of French officers wounded or killed in the Peninsular War, unfortunately my copy is several thousand miles away at the moment.
