29 May 1803, Havana. Wrote on 25 May about Francisco Arango’s return from Saint-Domingue. Nothing official has since transpired regarding his mission there, but Gray has learned from a reliable source that Arango was partly successful and that a convention between France and Spain was signed, stipulating “that each party shall be at liberty to have at the seat of Governt: of the other, one Agent or Commissary at least, to be charged with the concerns of his Government, and of its Citizens or subjects, and whom shall, be Publicly acknowledged as such.” “Whether this Convention will be made Public before it passes under the review of His Catholic Majesty and the First Consul for their assent, is uncertain,” but Gray believes “a French Agent will in a short time, be publicly acknowledged here; by order of the court of Madrid.” Should this convention, however, not be made public after the supreme council of the island approves it, Gray will obtain a copy and forward it to JM so that the U.S. may demand from Spain its rights under article 19 of the Treaty of San Lorenzo of 20 Oct. 1795.1
