Toussaint and Maitland signed at Arcahaye a secret convention that opened only the ports of the Cap and Port-au-Prince to foreign vessels.

Toussaint went to Arcahaye, where Maitland landed; on 13 June (25 prairial) they signed a secret convention. This convention, which was a veritable treaty from power to power, stipulated peace on land as at sea; Toussaint engaged “never to attempt anything, and to allow nothing to be attempted, against the English or American possessions; to forbid armed privateers, in the ports of his command, to molest in any manner the English or American merchant vessels that might come there to trade; to allow none of them to be condemned or sold; to have them restored on the contrary, even those that might be taken by the privateers of the other French islands and that might be conducted into the ports of Saint-Domingue subject to his command. Only the ports of the Cap and of Port-au-Prince were open; all vessels that sought to enter the other ports would be liable to confiscation; coasting is authorized, but the vessels that engage in it may not exceed fifty tons, or have more than nine men of crew, including a second captain; these coasters must not go farther than five leagues from the coast, from Monte-Cristo to the Môle; in the present situation none may navigate to the south of the island of La Gonâve, with the exception of those that shall pass by the North and make for Léogane and the two Goâves. Finally, no vessel of the powers may travel without letters signed by the English and American consuls, and by Toussaint.”
