had important economic interests that were being harmed by the prolonged conflict and deepening uncertainty about Cuba's future. Shipping firms that had relied heavily on trade with Cuba now suffered losses as the conflict continued unresolved. These firms pressed Congress and McKinley to seek an end to the revolt. Other American business concerns, specifically those who had invested in Cuban sugar, looked to the Spanish to restore order. Stability, not war, was the goal of both interests. How stability would be achieved would depend largely on the ability of Spain and the U.S. to work out their issues diplomatically. Lieutenant Commander Charles Train, in 1894, in his preparatory notes in an outlook of an armed conflict between Spain and the United States, wrote that Cuba was solely dependent on the trade activities that Spain was carrying out and that it would mean Spain would use their "entire forces" to defend it. While tension increased among the Cubans and Spanish Government, popular support of intervention began to spring up in the United States. Many Americans likened the Cuban revolt to the American Revolution, and they viewed the Spanish Government as a tyrannical oppressor. Historian Louis Pérez notes that "The proposition of war in behalf of Cuban independence took hold immediately and held on thereafter. Such was the sense of the public mood." Many poems and songs were written in the United States to express support of the "Cuba Libre" movement. At the same time, many African Americans, facing growing racial discrimination and increasing retardation of their civil rights, wanted to take part in the war. They saw it as a way to advance the cause of equality, service to country hopefully helping to gain political and public respect amongst the wider population. President McKinley, well aware of the political complexity surrounding the conflict, wanted to end the revolt peacefully. He began to negotiate with the Spanish government, hoping that the talks would dampen yellow journalism in the United States and soften support for war with Spain. An attempt was made to negotiate a peace before McKinley took office. However, the Spanish refused to take part in the negotiations. In 1897 McKinley appointed Stewart L. Woodford as the new minister to Spain, who again offered to negotiate a peace. In October 1897, the Spanish government refused the United States' offer to negotiate between the Spanish and the Cubans, but promised the U.S.
