Spanish-American War


Battleship Maine

Battleship Maine passes Morro Castle as it enters the Havana harbor, Cuba, 25 January 1898. It was destroyed the following month by an explosion that killed 266 American Sailors. The incident was a catalyst for the Spanish-American War. Naval History and Heritage Command photograph, NH 48619.

The Spanish-American War was preceded by three years of intense fighting by Cuban revolutionaries who sought to gain independence from Spanish colonial rule. From 1895–98, the conflict in Cuba captured the attention of the American public mostly because of the economic and political instability within close geographical proximity to the United States. The U.S. press and political establishment also had a role in stirring up American sentiment. By early 1898, tensions between the United States and Spain were mounting. After battleship Maine exploded and was sunk in the Havana harbor on 15 February 1898, U.S. military intervention in Cuba became likely. On 20 April, Congress passed a joint resolution that acknowledged Cuba’s independence, demanding that Spain give up control of the island and authorizing President William McKinley to use whatever military measures he deemed necessary to guarantee the independence of Cuba. The Spanish government saw no alternative but to rejecting U.S. demands and severing all diplomatic relations. McKinley responded by ordering a naval blockade of Cuba and issued an order for the call-up and deployment of 125,000 military personnel, termed “volunteers” at the time.

The first battle of the Spanish-American War occurred on 1 May. Opening with Commodore George Dewey's famous order, “You may fire when you are ready, Gridley,” the Navy's Asiatic Squadron defeated the Spanish squadron under the command of Spanish Admiral Patricio Montojo y Pasaron defending Manila Bay’s defense in just six hours . With cruisers Olympia, Raleigh, Boston, and Baltimore, gunboats Concord and Petrel, revenue cutter McCulloch, and with reinforcements from cruiser Charleston and monitors Monadnock and Monterey, the Asiatic Squadron forced the capitulation of Manila. During the battle, the entire Spanish squadron was sunk, which included cruisers Maria Cristina and Castilla, gunboats Don Antonio de Ulloa, Don Juan de Austria, Isla de Luzon, Isla de Cuba, Velasco, and Argos. After the Spanish squadron was destroyed, Dewey focused on silencing enemy shore batteries and awaited the arrival of land forces to capture Manila, the capital of the Philippines. By the end of July, some 11,000 U.S. troops were on the ground under the command of U.S. Army Major General Wesley Merritt, and by 13 August, Manila fell.

Meanwhile, attention centered on Cuba. On 27 May, under the command of Admiral William T. Sampson and Admiral Winfield S. Schley, the U.S. Navy successfully blockaded the port of Santiago. About two weeks later, U.S. Marines landed on Guantanamo Bay and additional forces landed near the port city of Santiago in late June. From 1–3 July, U.S. ground forces soundly defeated the Spanish army during the Battle of San Juan Heights. In an effort to escape capture after American ground forces prevailed, Admiral Pascual Cervera y Topete attempted to evade the U.S. blockade of Santiago harbor, but his squadron was demolished by the much more powerful U.S. naval forces. American ships destroyed Spanish destroyer Furor, torpedo boat Pluton, and armored cruisers Infanta Maria Teresa, Almirante Oquendo, Vizcaya, and Cristobal Colon. Ultimately, the Spanish lost all their ships and lost 350 personnel killed in action and 160 wounded.

At this point, the war was all but over due to the sheer dominance of the U.S. military’s superior naval and ground forces and because Spain was not prepared for a war with an up and coming world power. On 26 July, at the request of the Spanish government, the French ambassador in Washington, Jules Cambon, approached the McKinley administration to discuss peace terms. As a result of the talks, a cease-fire was signed on 12 August. The war officially ended four months later when the U.S. and Spanish governments signed a Treaty of Paris on 10 December 1898.

The war ended Spain’s colonial empire in the western hemisphere and also secured the position of the United States as a Pacific power. The U.S. victory compelled Spain to relinquish claims on Cuba, and to cede sovereignty over Guam, Puerto Rico, and the Philippines (the United States agreed to pay $20 million for the latter). The United States also annexed the territory of Hawaii as a result of the conflict. Consequently, the war enabled the United States to establish its predominance in the Caribbean region and to pursue strategic and economic interests in Asia. It also forged the way toward the construction of the Panama Canal, linking the Atlantic and Pacific oceans.
