The Secret Voyage of Sir Francis Drake: 1577-1580

On September 26, 1580, Francis Drake sailed his ship, the Golden Hinde, into Plymouth Harbor on the southwest coast of England. He had long been given up for lost, and rumors quickly circulated about where he had been on his three-year round-the-world voyage, and about the plunder he had brought home to fill Queen Elizabeth's treasury. However, a veil of secrecy was immediately imposed on the expedition: Drake's journals and charts were impounded, and his men were forbidden, on pain of death, to divulge where they had been―especially during the summer of 1579, when they had dropped from sight in the North Pacific.
In hindsight, Drake's journey was arguably the greatest sea voyage of all time. In a ship barely one hundred feet long, he sailed more than 40,000 miles, much of the voyage at extraordinary speed; disrupted the Spanish Empire in the New World; encountered often hostile native peoples on four continents; narrowly escaped disaster on numerous occasions; and became the first captain to circumnavigate the globe.
