Spanish-American war, 1898: The surprise explosion of the battleship Maine at Havana, Cuba. 255 of the crew died. The Hearst press accused the Spanish, claiming that the explosion was caused by a remote-controlled mine. The USA declared war on Spain, and conquered Philippines, Guam and Cuba. Subsequent investigations revealed that the explosion originated inside the Maine and that it was either an accident, such as a coal explosion, or some type of time bomb inside the battleship. Divers investigating the shipwreck found that the armour plates of the ship were blown bending outwards, not inwards.
