His successor, the Vicomte de Rochambeau, fought an even more brutal campaign. Rochambeau waged a near-genocidal campaign against the Haitians, killing everyone who was black. Rochambeau imported about 15,000 attack dogs from Jamaica, who had been trained to savage blacks and mulattoes. (Other sources suggest the dogs may have been dogo cubanos sourced in their hundreds from Cuba rather than Jamaica.) At the Bay of Le Cap, Rochambeau had blacks drowned. No one would eat fish from the bay for months afterward, as no one wished to eat the fish that had eaten human flesh. Bonaparte, hearing that most of his army in Saint-Domingue had died of yellow fever and the French held only Port-au-Prince, Le Cap, and Les Cayes, sent about 20,000 reinforcements to Rochambeau.
