HMS Erebus took part in the Ross expedition of 1839-1843, and was abandoned in 1848 during the third Franklin expedition. The sunken wreck was discovered by the Canadian Victoria Strait Expedition in September 2014. Erebus was refitted as an exploration vessel for Antarctic service, and on 21 November 1840 - captained by James Clark Ross - she departed from Van Diemen's Land for Antarctica in company with Terror. In January 1841, the crews of both ships landed on Victoria Land, and proceeded to name areas of the landscape after British politicians, scientists, and acquaintances. Mount Erebus, on Ross Island, was named after one ship and Mount Terror after the other.
