Both ships had become icebound and had been abandoned by their crews, totaling about 130 men, all of whom died from a variety of causes, including hypothermia, scurvy and starvation while trying to trek overland to the south. Subsequent expeditions until the late 1980s, and autopsies of crew members, also revealed that "Erebus" and "Terror"s shoddily 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.
