On 15 February 1898, the battleship USS Maine blew up in Havana Harbor, Cuba. The explosion was blamed on Spanish treachery, leading to the Spanish-American War and battle cries of “Remember the Maine!” To this day, the exact cause of the explosion remains unknown. Some studies point to an accidental ignition of the ammunition magazine due to a fire in the adjacent coal bunker, but this has never been proven definitively. This 1898 painting by A. Melero depicts the wrecked ship sitting on the bottom. NHHC Photo KN-10967.
