On the 16th of December 2008 HMS Endurance suffered a very sudden and catastrophic flood in the South Atlantic.

Tom Sharpe was in temporary command of the Royal Navy ice breaker as her engine room filled in less than half an hour, and she lost power in turbulent seas.

Tom tells Kate Gerbeau why he ignored advice from the UK to abandon ship, how he led his crew to save the ship from sinking, and how it gave him confidence to lead without being risk averse.
