(warning: sidetrack/sidenote)
Perhaps if the French had returned Toussaint Louverture's body to Haiti, the island's voodoo-curse could not have taken such terrible hold.
They apparently are physically incapable of returning the remains because they don't know where they are? I haven't investigated much, wikipedia claims (uncited) that France apparently returned a shovelful of dirt from the Fort where he died in prison as a symbolic thing and presumably that's because they don't know where the body is. A random internet-goer claiming to translate old French documents I saw claims the remains were tossed into a cave that was used for prisoners and soldiers and not marked, and then *that* was dug up and discarded in renovation-work in the late 1800s...No idea how reliable that is, though.
But, then, considering the number of British, French, Spaniards, slaves and indians dead just through 1802, the island's curse probably had enough fuel to get going without Louverture's spirit adding any haunted bonus points.
And now we've got gang-leader/warlord Barbecue.
