Where did you get the information about who is who in the images?
I have read a differently formulated list on the Napoléon Foundation's website. This site tells who is who in the finished painting (La mort du Napoléon). But I don't think the placing of these people differ between the two versions. However, four additional people have been added. I am not sure they really were with Napoleone Buonaparte when he died. In contrast I count on all the ones in the sketch being so.
