Sapeurs Pompiers, French firefighters.
Cantinieres attached to French fire fighting companies appear in photos and artwork. The early companies were organized more on military lines with members carrying weapons on parade. I don't know if these cantinieres were just for parades or served during fires. One below was noted as being on duty during the Franco-Prussian War.
This lady,Marie BEHEN, served during the Siege of Paris.
Here she is again in an earlier photo.
