Concept note-2: -On February 15, 1898, an explosion of unknown origin sank the battleship U.S.S. Maine in the Havana, Cuba harbor, killing 266 of the 354 crew members. The sinking of the Maine incited United States’ passions against Spain, eventually leading to a naval blockade of Cuba and a declaration of war.
Concept note-3: -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.
