Toussaint buys and sells land at Haut-du-Cap under a notary's seal

King found a run of notarial acts recording land transactions by Toussaint at Haut-du-Cap in these years, including a purchase from Philippe Jasemin, a parcel described as planted in coffee, and a later sale of part of a holding. Following Garrigus, he notes that free people of colour in the colony used notaries far more heavily than whites did, because in French practice a notary confirms the legality of a contract rather than merely witnessing signatures, and legal formality was a defence against rising racial prejudice. King extends the point to the quasi-free. A libre de savane risked arrest, and a notarial act could stand in for the manumission paper he did not have, since by definition only a free person could execute one. Every registered contract therefore strengthened the claim to freedom while also building an estate.

When the French government drew its colonial slave law together in 1685, it also stated that Africans who reached France as slaves could become free under French law and custom and could not be forced back to the West Indies. Owners found ways around it. A decree of 1716 let planters register enslaved people as having been brought over for education, which blocked their freedom claims. Read alongside the remnants of serfdom, that reasoning allowed four thousand enslaved people to be kept in France in 1738. Later, labour shortage in the colonies moved the government to order them shipped back, even though they returned carrying a spirit of independence. In 1777 a royal decree closed France to black and mixed race people, free and enslaved alike, allowing a West Indian owner only one personal servant while travelling. The stated reason was the well-being of the colonies. The following year a decree forbade black and white marriages in France.

Nine slave ships sailed from Le Havre in 1783 for the Loango coast, all of them bound for Saint-Domingue. Their names were L'Homme Instruit, L'Apollon, Le Neree, Le Roi Maure, La Marthe, L'Agamemnon, Le Prince Noir, Le Jason and Le Jeune Frederic. The armament records give three figures for each vessel: how many people it bought in Africa, how many died at sea, how many were put ashore in the colony. Together the nine bought 3,722 people. 458 died on the crossing. 3,264 were landed in Saint-Domingue. Le Jeune Frederic, which left on 25 September, bought 328 and lost 115 of them, more than a third. Le Neree lost 17 out of 432. Le Havre was one port among several, since Nantes and Dunkirk were fitting out for the same African coast in the same years. Loango lies north of the Congo river, and its people were the largest single group in the colony that became Haiti.

Dahomey paid an annual tribute to the Yoruba empire of Oyo for most of a century. Archibald Dalzel, drawing on Lionel Abson who ran the English fort at Whydah for over thirty years, described what happened when the envoys came to collect and Kpengla's second minister, the Meu, died. The envoys demanded a hundred of the dead man's women. Kpengla handed over some to be rid of them, and three months later the king of Oyo threatened invasion unless he received the rest. Rather than give up more Dahomean women, Kpengla sent troops into neighbouring Agouna to seize the number required. They were beaten back with heavy losses. Hearing this at midday, the king put on his cartridge box, shouldered his firelock and marched on Agouna at the head of eight hundred armed women. The enemy fled. Dalzel dated this to 1781, and documents show the Meu died in early 1779.
