Adventurous and wilful, the swashbuckling Martin Frobisher was both a brave sea-commander who served Elizabeth I with distinction and a privateer who single-mindedly pursued his own interests. This highly entertaining biography provides the first complete picture of the life and exploits of Frobisher, from his voyages in search of the fabled Northwest Passage to his courageous resistance to the Spanish Armada and his activities as privateer and sometime pirate. The book explores Frobisher's vigorous personality and its manifestation in the turbulence of his career and his impact on others. It also illuminates the robust world of maritime enterprise in the sixteenth century, when the shifting objectives of the Elizabethan age brought together felons, merchants, and great officers of state. James McDermott, a leading authority on Martin Frobisher and the Northwest Passage, offers a riveting account of the explorer, based on all extant manuscript and documentary sources. McDermott sets aside the distortions of Frobisher's popular reputation as a hero and offers instead a richly detailed portrait of a fascinating but flawed man whose ceaseless search for wealth and fame defined his extraordinary life.
