For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

In 1991, acting on a tip from a local fisherman, two scuba divers discovered a sunken German U-boat, complete with its crew of 60 men, not too far off the New Jersey coast. The divers, realizing the momentousness of their discovery, began probing the mystery.

Of the 300 men who had embarked on the journey, only four survived - three Spaniards and an African slave.

It was a moment unique in human history: the face-to-face meeting between two men from civilizations a world apart. In 1519, Hernán Cortés arrived on the shores of Mexico, determined not only to expand the Spanish empire but to convert the natives to Catholicism and carry off a fortune in gold. That he saw nothing paradoxical in his intentions is one of the most remarkable and tragic aspects of this unforgettable story.

On January 28, 1742, a ramshackle vessel of patched-together wood and cloth washed up on the coast of Brazil.

While the Wager had been chasing a Spanish treasure-filled galleon known as “the prize of all the oceans,” it had wrecked on a desolate island off the coast of Patagonia.

In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.
