Spanish-American War and Filipino Insurrection: Credo ReferencePresident William McKinley elected on the Republican ticket in 1896, was cautious but determined to support U.S. interests. He felt compelled in early 1898 to send the USS Maine to Havana harbor, where a few weeks later, it blew up. The “yellow press,” led by William Randolph Hearst's New York Journal, issued the battle cry “Remember the Maine.” Congress declared war in April 1898, but the U.S. fleet had already begun moving into position near Spanish possessions in both the Caribbean (Cuba and Puerto Rico) and the Pacific (Philippines). The small and undertrained U.S. Army was augmented by numerous enthusiastic volunteers, including the famous Rough Riders, organized by Teddy Roosevelt, who benefited from admiring publicity. The navy performed better than the army, but both performed better than the Spanish, and the fighting was over within a few weeks, costing the United States few dead, and most of those from disease rather than battle. During the war, the United States annexed Hawai'i. As a result of the war, although not until 1902, Cuba became independent. Puerto Rico, Guam, and the Philippines became U.S. colonies, technically called “unincorporated territories.”
