coal was carried. Iron plating was added fore and aft on the ships' hulls to make them more resistant to pack ice, and their decks were cross-planked to distribute impact forces. Along with Erebus, Terror was stocked with supplies for their expedition, which included among other items: two tons of tobacco, 8,000 tins of preserves, and of liquor. Terrors library had 1,200 books, and the ship's berths were heated via ducts that connected them to the stove. Their voyage to the Arctic was with Sir John Franklin in overall command of the expedition in Erebus, and Terror again under the command of Captain Francis Crozier. The expedition was ordered to gather magnetic data in the Canadian Arctic and complete a crossing of the Northwest Passage, which had already been charted from both the east and west, but never entirely navigated. It was planned to last three years. The expedition sailed from Greenhithe, Kent, on 19 May 1845, and the ships were last seen entering Baffin Bay in August 1845. The disappearance of the Franklin expedition set off a massive search effort in the Arctic and the broad circumstances of the expedition's fate were revealed during a series of expeditions between 1848 and 1866. Both ships had become icebound and were abandoned by their crews, all of whom died of exposure and starvation while trying to trek overland to Fort Resolution, a Hudson's Bay Company outpost to the southwest. Subsequent expeditions up until the late 1980s, including autopsies of crew members, revealed that their canned rations may have been tainted by both lead and botulism. Oral reports by local Inuit that some of the crew members resorted to cannibalism were at least somewhat supported by forensic evidence of cut marks on the skeletal remains of crew members found on King William Island during the late 20th century. Discovery of the wreckage On 15 August 2008, Parks Canada, an agency of the Government of Canada, announced a CAD$75,000 six-week search, deploying the icebreaker with the goal of finding the two ships. The search was also intended to strengthen Canada's claims of sovereignty over large portions of the Arctic. Further attempts to locate the ships were undertaken in 2010, 2011, and 2012, all of which failed to locate the ships' remains. On 8 September 2014, it was announced that the wreckage of one of Franklin's ships was found on 7 September using a
