On the night of August 13, 1944, the U.S. submarine Flier struck a mine in the Sulu Sea in the southern Philippines as it steamed along the surface. All but fifteen of the more than eighty-strong crew went down with the vessel. Of those left floating in the dark, eight survived by swimming for seventeen hours before washing ashore on an uninhabited island. The story of the Flier and its eight survivors is wholly unique in the annals of U.S. military history.
