HMS Erebus and HMS Terror ships and mysterious expedition

Franklin's lost expedition was a British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror. A Royal Navy officer and experienced explorer, Franklin had served on three previous Arctic expeditions. His fourth and last, was meant to traverse the last unnavigated section of the Northwest Passage. After a few early fatalities, the two ships became icebound in Victoria Strait, near King William Island in the Canadian Arctic. The entire expedition, comprising 129 men including Franklin, was lost.
