This article tells of Napoleon's supposed genocide in Haiti, and compares him to Hitler. I'm aware that this is still a matter of debate, since Napoleon wasn't anti-Semitic like the article says and other reasons, but I was wondering if there is any evidence of Napoleon committing genocide beyond what the article presents.
One of my favorite quotes from Chandler's The Campaigns of Napoleon which is basically The Bible of the Napoleonic Wars:
Since the 1940s it has been fashionable in some quarters to compare Napoleon to Hitler. Nothing could be more degrading to the former and more flattering to the latter. The comparison is odious. On the whole, Napoleon was inspired (in the early years at least) by a noble dream, wholly dissimilar from Hitler's vaunted but stillborn "New Order." Napoleon left great and lasting testimonies to his genius--in codes of law and national identities which survive to the present day. Adolf Hitler left nothing but destruction.
I do not know whether or not Napoleon asked about a chemical means of defeating the rebellion in Haiti but this rebellion is a rather odd part of the French Revolution. Ideally France should support the push of a people going toward liberty but in the end, they still needed their colonial empire. However, this article has many problems that it freely mentions:
Allegdly on Napoleon's orders, sulphur was extracted from Haitian volcanoes and burned to produce poisonous sulphur dioxide, which was then used to gas black Haitians in the holds of ships - more than 100,000 of them, according to records.
Allegedly (which they mispelt) is something that never holds up in historical discussion. I have answered this before (but cannot find it) and the largest problem I have is that a lot of the sources are questionable, thus are not fully acceptable.
Finally, the Daily Mail isn't a very credible source to begin with.
