Sir Francis Leopold McClintock (1819-1907) established his reputation as an Arctic explorer on voyages with Ross and Belcher, undertaking long and dangerous sledge journeys charting the territory. McClintock's account of his 1857-9 expedition on the yacht Fox through the North-West Passage to discover the fate of Arctic explorer Sir John Franklin and his ships, the Erebus and Terror, was first published in 1859. The journey was commissioned by Franklin's widow who, unhappy with the Admiralty's reluctance to seek confirmation of the account of her husband's expedition brought back in 1854 by explorer John Rae, commissioned McClintock to seek corroborating evidence. After a punishing voyage, including 250 days beset by ice in Baffin Bay drifting some 1,400 miles, the search continued by sledge. It was William Hobson, McClintock's second-in-command who found the written evidence documenting Franklin's death in 1847. The grim remains of others who had perished were also discovered.
