The battleship USS Maine explodes and sinks in Havana harbor in Cuba, killing about 274 of the ship's roughly 354 crew. The disaster pushes the United States to declare war on Spain.

USS Maine was a United States Navy ship that sank in Havana Harbor on February 15, 1898, contributing to the outbreak of the Spanish–American War in April. U.S. newspapers claimed that the Spanish were responsible for the ship's destruction, while evidence points to an accident caused by an internal coal bunker fire. The phrase "Remember the Maine! To hell with Spain!" became a rallying cry for action. The Maine explosion served as a catalyst which accelerated the events leading up to the war.
