In the summer of 1773 the 14-year old Horatio Nelson took part in an expedition to the Arctic, which came close to ending his naval career before it had begun. Two bomb vessels, and were fitted out and strengthened under the command of Captain Hon. Constantine Phipps for an expedition to find the Northwest Passage. It was an extremely cold Arctic summer and the ships became locked in ice unable to cut their way out for days until the wind changed and the ice broke up. The ships were eventually extricated and sailed home, and the legend of Horatio Nelson began. During the voyage, the young Nelson had command of one of the smaller boats of the ships, a four-oared cutter manned by twelve seamen. In this he helped save the crew of one of the boats from an attack by a herd of enraged walruses. He also had a more famous encounter with a polar bear while attempting to obtain a bearskin as a present for his father, an exploit that later became part of the Nelson legend. Drawing on the ship's journals, and expedition commander Phipps' log from the National Archives, creates a fascinating picture of the expedition and life on board. Using the ships' muster books it also details the ship's crews, explaining the different roles and ranks aboard. is illustrated using the ship's drawings, charts, as well as objects used aboard, accompanied by a navigational chart of the route taken. also examines the concept of naval exploration as put forth by Joseph Banks and the Royal Society. The near failure of the expedition as a result of poor planning—with potentially tragic results—demonstrates the difficulties and uncertainties of such expeditions. also provides a unique glimpse at a great naval commander at the earliest stage of his career, analyzing how the experience might have shaped his later career and attitudes. Other great captains and voyages are discussed alongside Nelson, including Captain Cook and his exploration of the south seas and the later ill-fated northern journeys of Franklin and Shackleton.
