The island's two tyrants meet once, on a salt flat, and never again

In December 1958 Duvalier signed a peace pact with Trujillo on the saline flats between the two countries, having first kept him waiting more than an hour in the sun. Photographing the scene, Diederich watched sweat cut channels through the Dominican dictator's makeup as he sat in a three piece suit in thirty eight degree heat. When Duvalier finally arrived the two exchanged sugary smiles and each promised to deny refuge to the other's enemies. Trujillo undertook in particular to protect Duvalier if the bearded rebel then in the Sierra Maestra came to power. A month later Castro was in Havana and Batista was in exile in Ciudad Trujillo. Diederich records that this was the first and last meeting between the two rulers of the island, and that Trujillo was assassinated in May 1961.

The end of colonial rule did not clear the board. African states came out of it carrying colonial administration, colonial economies and colonial borders, and at the same time older arrangements returned that colonial rule had only held down. A large share of what gets called a postcolonial problem is a nineteenth century one, above all the militarisation of politics that spread across the continent before any European army settled there. The Cold War made this worse, starting some conflicts, extending others, and giving Western governments a stated reason to fund rulers they could not otherwise have defended. Economic weakness ran back further, through colonial extraction to the terms of nineteenth century legitimate commerce and behind that to the Atlantic slave trade. Government by patronage drew on precolonial practice while distorting it. One year holds the whole ambiguity. In 1994 South Africans of every description voted together for the first time, and in the same months about eight hundred thousand people were killed in Rwanda in a hundred days.

Dag Hammarskjold, the second Secretary General of the United Nations, was flying to negotiate a ceasefire in the Congo war in 1961 when his aircraft came down in Northern Rhodesia. His bodyguards were Haitians and they died with him. Elizabeth Wilson, who was born in the Congo while her father Arnauld Wilson worked there as a public health engineer for the World Health Organisation, has written that several hundred people serving under the United Nations flag in the Congo were killed, many of them unnamed anywhere, and that the Haitian bodyguards were among them. She asks for a monument in Kinshasa, raised in the name of the United Nations, to everyone who lived and died there for an impossible ideal. Her own father is absent from the official record too. That absence is what she is arguing against, on behalf of a family memory and of a Haitian presence in Africa that nobody wrote down.

Yvonne Hakim-Rimpel belonged to the Ligue Feminine d'Action Sociale, founded in 1934. She had taken part in the parliamentary debates and the women's demonstrations of 1946 and 1950 for political rights and the vote. She wrote for La Voix des Femmes from 1935 and started her own twice-weekly paper, L'Escale, in 1951. She had supported Louis Dejoie in the 1957 election and began criticising the new government at once. On 6 January 1958, at half past eleven in the morning, armed men came to her house. Officers of the military household and civilians including Clement Barbot, Elois Maitre and Luc Desir beat her two daughters in front of her and took her away. At Delmas the group raped her in turn and beat her with rifle butts. Her fingers were broken and she was left for dead in a ditch. Rape entered Haitian state practice as a political weapon at that moment.
