In The Secret Voyage of Sir Francis Drake, Samuel Bawlf offers fascinating insight into life at sea in the sixteenth century, from the dangers of mutiny and the difficulty of understanding patterns of wind and current to the arduous physical challenges faced every day by Drake's men. But it is Bawlf's assertion of Drake's whereabouts in the summer of 1579 that gives his book its exciting originality. Based especially on his seminal study of maps produced after the voyage, Bawlf shows with certainty that Drake sailed all the way to Alaska, much farther north than anyone has heretofore imagined, thereby rewriting the history of exploration. He was, Bawlf claims, in search of the western entrance to the fabled Northwest Passage, at which he planned to found England's first colony, and wrest control of the Pacific from Spain. Drake's voyage was in fact so far ahead of its time that another 200 years would pass before the eighteenth-century explorers of record reached the northwest coast of North America.
