EXPLANATIONS BELOW
Concept note-1: -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.
Concept note-2: -No one has ever established exactly what caused the explosion or who was responsible, but the consequence was the brief Spanish-American War of 1898. American sentiment was strongly behind Cuban independence and many Americans blamed the Spanish for the outrage.
Concept note-3: -In 1976, however, in the aftermath of the Vietnam War, Admiral Hyman Rickover conducted a new investigation. Rickover, something of a maverick in the Navy, came to the conclusion that the explosion was caused by spontaneous combustion in the ship’s coal bins, a problem that afflicted other ships of the period.
Concept note-4: -USS Maine, a second-class battleship built between 1888 and 1895, was sent to Havana in January 1898 to protect American interests during the long-standing revolt of the Cubans against the Spanish government. In the evening of 15 February 1898, Maine sank when her forward gunpowder magazines exploded.
