That's great thanks. Thanks for letting me know what happened to the heart in 1816. So, between 1804 and 1816, it is likely to have been attached to the flag of a regiment. I don't think it can have been the 34th DB, however, as that unit didn't go to Saint-Domingue or Cuba and I don't think it had a special connection to Noailles. The 31st did participate in the campaign, and had formed part of the garrison at Le Mole under Noailles. But I can't find any evidence to pin the heart of the general to that flag!
