Many thanks!

I think for 1815 it is probably-certainly the 7°Jäger-Bataillon as indicated for 1816

he was Place commander in Le Puy but that is the context of the Austrian occupied zone in France, the largest of the Allied forces, where Austrian generals and officers from units of the Armies of Upper Italy, Naples etc... in garrison in France assuming such provisionnal commands in the occupied departments and cities

and as the Departemental commander in Upper Loire was initially the Generalmajor Bogdan, and his Brigade had both 7° and 9° Jäger-Bataillon with Cavalry and Grenzer
