Dessalines gives children a legal standing without a wedding

Under French law a child born outside marriage could not inherit, and a parent was not free to leave property as he wished, being obliged to pass it to legitimate heirs. In the new Haitian state an enormous number of children had no standing under any such rule. On 28 May 1805 Jean-Jacques Dessalines issued a law that removed the distinction. There was to be no preference for children born in wedlock. A child's capacity to inherit turned on recognition by a parent. The measure was designed to settle inheritance disputes before they began. Its effect on marriage ran the other way from what the founders intended. A wedding in Haiti cost a civil licence, a payment to the priest and his assistants, clothes bought for the church, a feast afterwards and several days away from work. Once children could inherit without one, the expense had lost its point, and legal marriage stayed rare for the next two centuries.

On 4 December 1804 General Louis Ferrand wrote to the Superior Council of Santiago about a ship he had sent to Charleston, South Carolina. Aboard it were people he called black brigands, meaning Haitians his forces had captured. The vessel had come back to Santo Domingo carrying a quantity of rice obtained in the exchange. Ferrand put his revenue at one thousand to twelve hundred gourdes. South Carolina grew rice with enslaved labour and was one of the richest plantation economies in the antebellum United States, so the trade pushed captives into a market that would absorb them and returned a staple food to a colony that grew very little. Ferrand had served in the American Revolution and knew the country he was dealing with. In those same first two years of Haitian independence the United States was Haiti's most important commercial partner, and in 1806 it criminalised that trade. American ports could buy from Haiti and buy Haitians inside the same decade.

Yellow fever reached the French expeditionary army in Saint-Domingue within weeks of its victory. Doctors first took it for plague. The sick complained of violent pain, then fever and thirst and vomiting, the tongue thickened, the gums blackened, the skin turned yellow, and death came within three days or between the seventh and the eleventh. Cold drinks, baths, bleeding, emetics and mild purgatives were tried and did nothing. On 1 August 1802 a squadron from Toulon under Rear Admiral Dumanoir anchored in the roadstead at Cap with three thousand men aboard, and on 7 August three transports arrived with two thousand more. They were given no time to acclimatise and in under twenty days all of them had been swept away. The funeral tables kept by the expedition itself record more than thirty five thousand men dead in this period. Corpses were collected by cart at night and tipped into a common pit.

When war resumed between France and England, the authorities in Jamaica expelled the French refugees on the island who had never been naturalised. Many of them had fled Saint-Domingue a decade earlier and were now moving a second time. At least a thousand reached the territory the United States had just bought from France, and the true figure may be higher. On 26 February 1804 Governor William Claiborne wrote that several hundred French emigrants from Jamaica were on the Mississippi River and that two or three more vessels full of passengers were expected daily. On 13 April he recorded a boat on the river with a hundred and fifty French passengers from Jamaica. Some arrived with enslaved people who were probably never counted as refugees. Baptismal records at the Saint Louis Cathedral in New Orleans show children born there in 1804 and 1805 whose older brothers and sisters had been born in Jamaica between 1798 and 1803, which is the shape of a family that fled twice.
