It is a proposal from Berthier to Napoleon to form a mounted company as follows:
1 Captain (commanding), 3 lieutenants, 1 adjutant sou officier, 1 medical officer, 3 marechaux de logis, 3 fourriers, 6 brigadiers, 3 farriers, 3 trumpeters, and 180 troopers. They are drawn from well-to-do families from the environs of Paris since the service d'ordonnaces is a "painful service should be done with exactitude and security by the regiments of the cavalry who arrive from the army to rebuild and whose men do not know all the detours of this immense city."
So perhaps a staff unit for the use of the minister of war (at this point, Berthier) for all manner of staff duties around Paris.
In any event, the editor notes that "this proposal was not followed through. There were other more important issues. Berthier left the Ministry of War on April 4, 1800, to take the command of the Reserve Army and the 'well-to-do families" of young men, to be more useful in the formation of volunteer hussars on foot and mounted that were created at this time."
