It took four more months and four attempts with help from the Norwegians, and from Uruguay and Chile, before Shackleton finally managed to negotiate a way through the pack ice aboard the steam tug Yelcho, lent to him by the Chilean government, to rescue his remaining twenty-two men.

That boat journey aboard the James Caird was a supreme act of human courage. Not a single man of Shackleton ‘s original twenty-eight men was lost. And though Endurance was lost, the James Caird survives to this day as a living reminder of an act of remarkable courage in the heroic age of exploration.
