A hundred years ago Sir Ernest Shackleton’s hopes of traversing Antarctica evaporated when the Endurance caught in an icy grip finally sank leaving 28 men facing an appalling battle to survive on both sea and ice. On the opposite side of the continent the Ross Sea party were facing their own horrors. Their well-stocked ship, the SY Aurora, was torn from its moorings, taking with it most of their supplies. Unaware that the Endurance men were stranded, they resolutely scavenged enough provisions to lay depots for Shackleton’s advancing party - a party that would never arrive. Their story remains as one of the greatest accounts of self-sacrifice in the annals of Polar history.
