James Knight’s 1719 Northwest Passage expedition wrecked at Marble Island in today’s Nunavut, where the survivors built a shelter and tried to overwinter. According to Inuit accounts later recorded by explorer Samuel Hearne, their numbers dwindled over two winters, and by the summer of 1721 all had died. The story is supported by Hearne’s interviews and by the remains of the ships and camp seen on Marble Island, rather than by any written message left by the crew.
