DE LA BLOTTIERE. Les frontières de France, Savoie, 1891

François de La Blottière (1673-1739), engineer-geographer, he was commissioned by Vauban to make several reconnaissances in the Alps and took part in the campaigns of Piedmont and the Alps from 1701 to 1713.

"More than thirty memoirs of La Blottière, relating to this part of the Alps are preserved in the archives of the depot of war and of the depot of fortifications. The memoir dated 1721 that we publish here forms a complete summary of the general knowledge that the eminent collaborator of Vauban was able to collect on the ground even during his numerous travels through the mountains of Dauphiné, Savoie and Piedmont." Henry Duhamel.
