How was General Dumas (a black French general during the Revolutionary and Napoleonic wars) seen by the French and the other European nations at the time?

by ChickenByNight

Do we also have examples of racist propaganda aimed against him or was his colour of skin not seen as such a big deal as it would have been in, say, mid 19th century America? Was the French population and French soldiers accepting of having a black general or are there examples of soldiers or officers refusing to serve under him?

I have a follow up question: How was he viewed in Haiti and by the revolutionary movement there?
