During the Spanish-American War, U.S. forces launch their invasion of Puerto Rico, the 108-mile-long, 40-mile-wide island that was one of Spain’s two principal possessions in the Caribbean. With little resistance and only seven deaths, U.S. troops under General Nelson A. Miles were able to secure the island by mid-August. After the signing of an armistice with Spain, American troops raised the U.S. flag over the island, formalizing U.S. authority over its one million inhabitants. In December, the Treaty of Paris was signed, ending the Spanish-American War and officially approving the cession of Puerto Rico to the United States.
