Today in 1909 Sir Ernest Shackleton reached his furthest "south" in his quest for the Pole. As he said at 88 degrees South latitude, "we've shot our bolt." The next Englishman to attempt to reach the Pole was Sir Robert Scott and he and his party died on the return.
In 1914 Shackleton attempted to cross Antarctica but his ship, Endurance, was trapped in the ice. What followed was one of the most heroic tales of exploration ever accomplished.
Shackleton never lost a man on any expedition he commanded.
