Explanation:
On April 25, 1898 the United States declared war on Spain following the sinking of the Battleship Maine in Havana harbor on February 15, 1898. The war ended with the signing of the Treaty of Paris on December 10, 1898. As a result Spain lost its control over the remains of its overseas empire -- Cuba, Puerto Rico, the Philippines Islands, Guam, and other islands.
Background
Beginning in 1492, Spain was the first European nation to sail westward across the Atlantic Ocean, explore, and colonize the Amerindian nations of the Western Hemisphere. At its greatest extent, the empire that resulted from this exploration extended from Virginia on the eastern coast of the United States south to Tierra del Fuego at the tip of South America excluding Brazil and westward to California and Alaska. Across the Pacific, it included the Philippines and other island groups. By 1825 much of this empire had fallen into other hands and in that year, Spain acknowledged the independence of its possessions in the present-day United States (then under Mexican control) and south to the tip of South America. The only remnants that remained in the empire in the Western Hemisphere were Cuba and Puerto Rico and across the Pacific in Philippines Islands, and the Carolina, Marshall, and Mariana Islands (including Guam) in Micronesia.
Cuba
Following the liberation from Spain of mainland Latin America, Cuba was the first to initiate its own struggle for independence. During the years from 1868-1878, Cubans personified by guerrilla fighters known as mambises fought for autonomy from Spain. That war concluded with a treaty that was never enforced. In the 1890's Cubans began to agitate once again for their freedom from Spain. The moral leader of this struggle was José Martí, known as "El Apóstol," who established the Cuban Revolutionary Party on January 5, 1892 in the United States. Following the grito de Baire, the call to arms on February 24, 1895, Martí returned to Cuba and participated in the first weeks of armed struggle when he was killed on May 19, 1895.
The War
Following its declaration of war against Spain issued on April 25, 1898, the United States added the Teller Amendment asserting that it would not attempt to exercise hegemony over Cuba. Two days later Commodore George Dewey sailed from Hong Kong with Emilio Aguinaldo on board. Fighting began in the Phillipines Islands at the Battle of Manila Bay on May 1 where Commodore George Dewey reportedly exclaimed, "You may fire when ready, Gridley," and the Spanish fleet under Rear Admiral Patricio Montojo was destroyed. However, Dewey did not have enough manpower to capture Manila so Aguinaldo's guerrillas maintained their operations until 15,000 U.S. troops arrived at the end of July. On the way, the cruiser Charleston stopped at Guam and accepted its surrender from its Spanish governor who was unaware his nation was at war. Although a peace protocol was signed by the two belligerents on August 12, Commodore Dewey and Maj. Gen. Wesley Merritt, leader of the army troops, assaulted Manila the very next day, unaware that peace had been declared.
War actually began for the U.S. in Cuba in June when the Marines captured Guantánamo Bay and 17,000 troops landed at Siboney and Daiquirí, east of Santiago de Cuba, the second largest city on the island. At that time Spanish troops stationed on the island included 150,000 regulars and 40,000 irregulars and volunteers while rebels inside Cuba numbered as many as 50,000. Total U.S. army strength at the time totalled 26,000, requiring the passage of the Mobilization Act of April 22 that allowed for an army of at first 125,000 volunteers (later increased to 200,000) and a regular army of 65,000. On June 22, U.S. troops landed at Daiquiri where they were joined by Calixto García and about 5,000 revolutionaries.
Representatives of Spain and the United States signed a peace treaty in Paris on December 10, 1898, which established the independence of Cuba, ceded Puerto Rico and Guam to the United States, and allowed the victorious power to purchase the Philippines Islands from Spain for $20 million. The war had cost the United States $250 million and 3,000 lives, of whom 90% had perished from infectious diseases.
