Your note appears to relate to p. 107 which is part of the "Emplacement des troupes de la Grande Armée sur les lieux de passage du Niémen, le 23 juin 1812", which starts on p. 106. The information of your note matches the information on p. 107.

I did a Google search using: "Garde royale italienne" + "1812" - without success.

Yours, in firm research,

Steve
