I have a reprint of the "Voyage pittoresque et militaire en Espagne, Catalogne : accompagné de notes explicatives sur les batailles, communiquées par M. M. le Maréchal Gouvion St. Cyr", according to the title page by "son Aide de Camp" M. C. Langlois, see for example https://www.abebooks.de/servlet/BookDetailsPL?bi=31171369734
Further on, there exist at least two paintings from the Russian campaign, 1812 ("The Battle of Smolensk" and "The Burning of Moscow"), obviously by Jean-Charles Langlois, known as "The Colonel" (1789-1870), cf. https://en.wikipedia.org/wiki/Jean-Charles_Langlois and https://fr.wikipedia.org/wiki/Jean-Charles_Langlois . I believe, this Langlois was (in 1812) a young Sous-Lieutenant of the 48th Ligne, sometimes mentioned by Pelet in his memoirs of the combat of Krasnoe, Carnet de la Sabretache, 1906, pp. 519ff; and in Martinien's Tableaux, p. 230. But in the French Wikipedia entry Jean-Charles seems to be confused / mixed with M. C. Langlois, at least this is my impression.
Any ideas, who was M. C. Langlois?
Best regards, Thomas
This is why I was mislead: Pelet's editor (vicomte d'Avout) writes in the above mentioned "Sabretache" article in a footnote about Sous-Lieutenant Langlois of the 48th Ligne (Pelet was in autumn / winter 1812 colonel of this regiment): "...Chompré, Langlois, lieutenants au 48e. Devenu colonel, et du plus artiste de talent, Langlois fut l'auteur des célebres panoramas de batailles, les Pyramides, Isly, Sébastopol." ( https://gallica.bnf.fr/ark:/12148/bpt6k115360s/f550.item )
In my further research I found a detailed biography of J.-C. Langlois in:
Dérozier, C., La campagne d'Espagne : lithographies de Bacler d'Albe et Langlois. Paris: Les belles Lettres, 1971, vol. I, pp. 77ff.
Thank you very much, gentlemen!
How about M(onsieur) C(harles) Langlois as "Charles" apparently was his "call name"?
as for M. M.: "Messieurs", as Gouvion St. Cyr is not the only person mentioned but: "...par M.M. le Maréchal Gouvion St. Cyr, les Généraux de Caen, Lamarque, Souham, Petit, etc."
[The seller seems to have read "E. Langlois" by mistake instead of "C. Langlois"?]
P.S. The French Wikipedia list of persons named "Langlois" (https://fr.wikipedia.org/wiki/Langlois ) has Jean-Charles, but obviously no "M.C. Langlois".
