February 15, 1898

The Maine explodesA massive explosion of unknown origin sinks the battleship USS Maine in Cuba's Havana harbor, killing 260 of the fewer than 400 American crew members aboard.

One of the first American battleships, the Maine weighed more than 6,000 tons and was built at a cost of more than $2 million. Ostensibly on a friendly visit, the Maine had been sent to Cuba to protect the interests of Americans there after a rebellion against Spanish rule broke out in Havana in January.

An official U.S. Naval Court of Inquiry ruled in March that the ship was blown up by a mine, without directly placing the blame on Spain. Much of Congress and a majority of the American public expressed little doubt that Spain was responsible and called for a declaration of war.

Subsequent diplomatic failures to resolve the Maine matter, coupled with United States indignation over Spain's brutal suppression of the Cuban rebellion and continued losses to American investment, led to the outbreak of the Spanish-American War in April 1898.

Within three months, the United States had decisively defeated Spanish forces on land and sea, and in August an armistice halted the fighting. On December 12, 1898, the Treaty of Paris was signed between the United States and Spain, officially ending the Spanish-American War and granting the United States its first overseas empire with the ceding of such former Spanish possessions as Puerto Rico, Guam, and the Philippines.

In 1976, a team of American naval investigators concluded that the Maine explosion was likely caused by a fire that ignited its ammunition stocks, not by a Spanish mine or act of sabotage.

O.k. that's a very nice story. However as I recall this war was born out of one of the greatest achievements of Yellow Journalism ever recorded. As stated the initial investigation didn't blame Spain. However in an effort to sell papers Spain was set up promptly bitch-slapped, when most that had any true knowledge had their doubts about Spain from the beginning.

The U.S. Navy Department immediately formed a board of inquiry to determine the reason for Maine's destruction. The inquiry, conducted in Havana, lasted four weeks. The condition of the submerged wreck and the lack of technical expertise prevented the board from being as thorough as later investigations. In the end, they concluded that a mine had detonated under the ship. The board did not attempt to fix blame for the placement of the device.
When the Navy's verdict was announced, the American public reacted with predictable outrage. Fed by inflammatory articles in the "Yellow Press" blaming Spain for the disaster, the public had already placed guilt on the Spanish government. Although he continued to press for a diplomatic settlement to the Cuban problem, President McKinley accelerated military preparations begun in January 1898 when an impasse appeared likely. The Spanish position on Cuban independence hardened, and McKinley asked Congress on 11 April for permission to intervene. On 21 April, the President ordered the Navy to begin a blockade of Cuba, and Spain followed with a declaration of war on 23 April. Congress responded with a formal declaration of war on 25 April, made retroactive to the start of the blockade.
The destruction of Maine did not cause the U.S. to declare war on Spain, but it served as a catalyst, accelerating the approach to a diplomatic impasse. In addition, the sinking and deaths of U.S. sailors rallied American opinion more strongly behind armed intervention.
In 1911 the Navy Department ordered a second board of inquiry after Congress voted funds for the removal of the wreck of Maine from Havana Harbor. U.S. Army engineers built a cofferdam around the sunken battleship, thus exposing it, and giving naval investigators an opportunity to examine and photograph the wreckage in detail. Finding the bottom hull plates in the area of the reserve six-inch magazine bent inward and back, the 1911 board concluded that a mine had detonated under the magazine, causing the explosion that destroyed the ship.
Technical experts at the time of both investigations disagreed with the findings, believing that spontaneous combustion of coal in the bunker adjacent to the reserve six-inch magazine was the most likely cause of the explosion on board the ship. In 1976, Admiral Hyman G. Rickover published his book, How the Battleship Maine Was Destroyed. The admiral became interested in the disaster and wondered if the application of modern scientific knowledge could determine the cause. He called on two experts on explosions and their effects on ship hulls. Using documentation gathered from the two official inquiries, as well as information on the construction and ammunition of Maine, the experts concluded that the damage caused to the ship was inconsistent with the external explosion of a mine. The most likely cause, they speculated, was spontaneous combustion of coal in the bunker next to the magazine.
Some historians have disputed the findings in Rickover's book, maintaining that failure to detect spontaneous combustion in the coal bunker was highly unlikely. Yet evidence of a mine remains thin and such theories are based primarily on conjecture. Despite the best efforts of experts and historians in investigating this complex and technical subject, a definitive explanation for the destruction of Maine remains elusive.
