Decoration given by Napoleon III - Need help to find out if Michel Zufferey had one

[vacottet]

Hello, I am looking to confirm if Michel Zufferey has effectivtly received a decoration from Napoleon III in the 1870's. I found this information in some swiss newspaper. DOes any one can give some tips where to look at ? I have already looked at the base Leonore but without success!

Here is the extract in english and french of the articles:
FRENCH:
Après 2 ans passés au service de l'Ambassadeur, ce dernier rentre à Paris en 1869 et recommande vivement le jeune Michel Zufferey, lequel immédiatement remarqué par Napoléon III, est mis au service de la princesse Eugénie son épouse, au titre de courrier secret. En 1870, tandis que la France connaît la première invasion, Napoléon III l'envoie en mission spéciale à Metz, alors investi pour y apporter des ordres, mission que Michel Zufferey accomplira avec succès. , Napoléon III doit quitter la France pour l'Angleterre, non sans que ce dernier remette à Michel Zufferey une distinction, que ce dernier se plaisait, dans ses vieux jours, à montrer à ses intimes sierrois, rappelant les souvenir des péripéties du siège de Paris en 1870, parlant de la chasse aux vivres, truffant sa discussion de quelques anecdotes sur la cour de Napoléon III.

ENGLISH
After 2 years in the service of the Ambassador, he returned to Paris in 1869 and strongly recommended the young Michel Zufferey, who was immediately noticed by Napoleon III, to Princess Eugénie his wife, as a secret letter. In 1870, while France was undergoing its first invasion, Napoleon III sent him on a special mission to Metz, then invested with the task of bringing orders to it, a mission that Michel Zufferey successfully accomplished. Napoleon III had to leave France for England, not without the latter giving Michel Zufferey a distinction, which he enjoyed, in his old days, showing his close friends, recalling the memories of the adventures of the siege of Paris in 1870, talking about the food hunt, stuffing his discussion with a few anecdotes about Napoleon III's court.
