The resulting dispatch, drafted at Aix-la-Chapelle and sent in October 1854, outlined the reasons a U.S. purchase of Cuba would be beneficial to all parties involved and declared that the U.S. would be "justified in wresting" the island from Spanish hands if Spain refused to sell. To Marcy's chagrin, the flamboyant Soulé had made no secret of the meetings, causing unwanted publicity in both Europe and the U.S. In the increasingly volatile political climate of 1854, the administration feared the political repercussions of making the dispatch's contents known, but pressure from journalists and politicians alike continued to mount.

Cuba was of special importance to Southern Democrats, whose economic and political interests would be best served by the admission of another slave state to the Union.

The Pierce administration


At Pierce's inauguration, he stated, "The policy of my Administration will not be controlled by any timid forebodings of evil from expansion." While slavery was not the stated goal nor Cuba mentioned by name, the antebellum makeup of his party required the Northerner to appeal to Southern interests, so he favored the annexation of Cuba as a slave state. To this end, he appointed expansionists to diplomatic posts throughout Europe, notably sending Pierre Soulé

 on U.S. policy toward Cuba. He had previously written to Soulé that, if Cuba's purchase could not be negotiated, "you will then direct your effort to the next desirable object, which is to detach that island from the Spanish dominion and from all dependence on any European power" – words Soulé may have adapted to fit his own agenda. Authors David Potter and Lars Schoultz both note the considerable ambiguity in Marcy's cryptic words, and Samuel Bemis suggests he may have referred to Cuban independence but acknowledges it is impossible to know Marcy's true intent. In any case, Marcy had also written in June that the administration had abandoned thoughts of declaring war over Cuba, yet Robert May writes, "the instructions for the conference had been so vague, and so many of Marcy's letters to Soulé since the Black Warrior incident had been bellicose, that the ministers misread the administration's intent."
After a minor disagreement about the location of the meeting, the diplomats met in Ostend, Belgium from October 9–11, 1854, then adjourned to Aix-la-Chapelle for a week to prepare a report of the proceedings. The resulting dispatch, which would come to be known as the Ostend Manifesto, declared that "Cuba is as necessary to the North American republic as any of its present members, and that it belongs naturally to that great family of states of which the Union is the Providential Nursery".

Prominent among the reasons for annexation outlined in the manifesto were fears of a possible Haiti-type slave revolt in Cuba in the absence of U.S. intervention. The Manifesto urged against inaction on the Cuban question, warning "We should, however, be recreant to our duty, be unworthy of our gallant forefathers, and commit base treason against our posterity, should we permit Cuba to be Africanized and become a second St. Domingo

Thus, it stipulated that the U.S. would be "justified in wresting" Cuba from Spain if the colonial power refused.

. One historian would conclude in 1893, "When we take into account the characteristics of the three men we can hardly resist the conclusion that Soulé, as he afterwards intimated, twisted his colleagues round his finger."
