hello
I know that the compagnies d'infirmiers disbanded in 1814 were restored by a decree of 17th april 1815 under Louis Fonteneau-Dufresne as 1er Bataillon de soldats d'ambulance these 8 companies more a 9th depôt company were disbanded the following 4th october 1815 in Poitiers
no found more about their activities during the Hundred Days...
