The French governor flees his own colonists into Spanish territory

Yingling uses the border as his instrument for reading the whole island, and this crossing is his sharpest illustration. In March 1791 the French governor of Saint-Domingue took refuge in Santo Domingo from white crowds in Port-au-Prince stirred up by the revolution in France. The route he used was the one already worn by maroons, merchants, cattle herders, exiles and families, and it had just been used by the free coloured dissidents he had helped condemn. The colony had been coming apart since 1789: elected assemblies and militias had undermined the governor's authority, the Colonial Assembly of Saint-Marc had drafted a constitution rebuffing metropolitan oversight and flirting with independence, and petits blancs in Port-au-Prince confronted him with demands modelled on the sans-culottes. Spanish observers concluded the French colony was already lost.

The turning point in Fleurant's account of Haiti is the ritual and political congress held by runaway slaves near Cap Francais in 1791, known as Bwa Kayiman. Calling it a congress rather than only a ceremony is the substance of the claim. The gathering produced a general slave uprising, which became a war of national liberation, which ended in the proclamation of independence on 1 January 1804. Colonial law in Saint-Domingue had banned any meeting of slaves by day or night and had made a policy of mixing people of different African origins on the same estate, so that language, lineage and any tie to the homeland they called Ginen would be lost for good. The religion is what defeated that policy. It bound together people from a wide range of African societies and gave them a common reason to strike, and the success of the revolt owed a great deal to that cohesion.

Measuring rebellions by the number of people involved, Geggus finds that no mainland American revolt appears to have mobilised more than a thousand enslaved people, and that only the Louisiana rising of 1811 passed a hundred in North America. The West Indies and Guianas produced eight or nine that reached a thousand or more. Within that group the rising on the northern plain of Saint-Domingue is in a class of its own for magnitude, length and outcome, and it triggered further revolts elsewhere in the colony, at Leogane and Jacmel and on the Cul de Sac plain in early 1792, at Anse a Veau and on the Cayes plain the same year, and possibly in the Artibonite. He notes that in the biggest cases historians stop counting armed men and start estimating everyone living in rebel held ground, which makes the figures soft.

On 19 May 1791 the ship Charming Sally tied up at Philadelphia and fifteen people from Saint Domingue came ashore. Five more ships over the following six weeks carried thirty nine others. Eight more between July and December brought eighty two. The traffic then changed character. Nine vessels reached the city in March and April 1792 with thirty seven passengers, sixteen ships in May with one hundred and seventy nine, and another two hundred and forty four people landed between June and August. Over the next thirty months more than three thousand people who had left the French colony entered Philadelphia. The city was then the seat of the national government and the busiest American port for coffee grown on the island, so the news and the people arrived together. Pennsylvania had passed gradual abolition laws in 1780 and 1788 that freed anyone brought into the state and held for six months by an owner settling there, which made the arrival of slaveholders a legal problem from the first week.
