 On April 27, U.S. ships, the monitor USS Puritan, the armored cruisers USS New York, and the USS Cincinnati, bombarded the Spanish fortifications at Matanzas Bay in Cuba. By July 16, an armistice was signed at the Arbol de La Paz (a large ceiba tree) in Santiago de Cuba by U.S. and Spanish forces ending hostilities in Cuba and its waters. The United States then directed its undivided military resources to Puerto Rico. Two leaders of the Puerto Rican section of the Cuban Revolutionary Party, Dr. Julio J. Henna and Roberto H. Todd, had written to U.S. President McKinley asking that Puerto Rico be included in whatever intervention was planned for Cuba as early as March 10. They even provided the U.S. government with information about the Spanish military presence on the island.
