A man looking for his horse reports the Virgin at Saut d'Eau

Fortune Morose was looking for his horse in the woods near the falls at Ville-Bonheur in 1849 when he heard leaves moving overhead. He looked up, saw the Virgin Mary, and ran to the police station. He returned with an officer and she had gone, leaving her image on a large palm leaf. People came in from the surrounding country to see whether the picture was still there and waited for the leaf to drop. About a month later it fell bare, and the same image had appeared on another leaf. Faustin Soulouque, crowned emperor two years before, sent his entire cabinet to inspect the site. On their report he decreed a church at Ville-Bonheur under the title of Our Lady of Mount Carmel, whose feast falls on 16 July. He wanted religious sanction for his campaigns to retake the eastern half of the island. Haitians have climbed to Sodo in mid-July ever since.

Until the Second Republic he had remained a technical expert, oddly isolated from both the radical republican and the abolitionist movements, writing for journals including La Reforme. The revolution brought the republicans to power and gave him the chance to apply what he had argued since 1840, that emancipation must be immediate and unqualified, that racial equality follows from it, and that emancipation without citizenship leaves freedom without substance. As undersecretary of state for the colonies he headed the commission that abolished slavery in the French colonies. He was then elected by the freed populations of Martinique and Guadeloupe to represent them. He returned to France after the fall of the Empire in August 1870, was elected again by Martinique in 1871, and spent the rest of his life as the recognised spokesman for antislavery and for the memory of Toussaint Louverture, dying in 1893.

The crisis that ended Boyer's rule opened into peasant insurrection. Jean-Jacques Acaau and Jeannot Moline led risings from 1843 to 1848 known as the war of the Piquets. Their demands were land, better prices for produce and a black man in the presidency. The scale of the fighting pushed the governing groups into alliance against the peasantry. The device they used has a name in Haitian political language, the politique de doublure, the understudy policy. Black men drawn from the ruling strata were placed in the presidency while the mulatto oligarchy governed from behind, smothering the political claims of the men it had installed along with the movements in the countryside. Men handled this way were called kongo, a word still used in Haiti for a black man who has sold himself and collaborates without pride. Acaau is credited with the saying that a rich black is a mulatto and a poor mulatto is a black.

In the 1850s despair at the Fugitive Slave Law and at tightening restrictions across the northern states pushed black leaders to reopen a question many had closed. Boyd quotes Frederick Douglass, a firm opponent of African colonisation, telling Americans in 1853 that the continent and the nearby islands already held more than twelve million people of African descent who needed only organisation to become one powerful nation. The emigration convention held at Cleveland in 1854 sent James Theodore Holly to Haiti to open discussions with the government of Faustin Soulouque, but the regime fell before anything was settled and a new republic under Fabre Geffrard took its place. Geffrard also wanted colonists from the United States, and several hundred people sailed from New Orleans for Port-au-Prince in 1859. What was still missing, in Boyd's account, was a definite programme.
