In the early years of Queen Victoria’s reign, HMS Erebusundertook two of the most ambitious naval expeditions of all time.

On the first, she ventured further south than any human had ever been. On the second, she vanished with her 129-strong crew in the wastes of the Canadian Arctic.

Her fate remained a mystery for over 160 years.

Then, in 2014, she was found.

This is her story.
