What happened

The 1845 Franklin Northwest Passage expedition was an unprecedented disaster in the history of British polar exploration, with the loss of all 129 officers and crew and the discovery ships HMS Erebus and HMS Terror.

Why it matters

The catastrophe has been the subject of novels, films and television series, as well as active research across several disciplines.

Common ground

In recent years, remarkable advances have been made, most notably the discoveries of the wrecks of both ships in astonishing states of preservation, which offer great potential for a new understanding of the expedition’s fate.
