After Amundsen reached the South Pole, Shackleton decided to lead an expedition across Antarctica, something that no one had done before.
Shackleton, 27 men, and 69 dogs boarded a ship called the Endurance and sailed in December 1914. By the end of January, the Endurance had sailed through miles of pack ice surrounding the continent and could go no farther.
Winter came, sunlight dwindled, and the ice thickened, grinding against the ship’s wooden hull. For ten months, the men waited for a break in the ice, but none came. In October, the ice crushed the ship’s hull, shattering it into splinters while the men watched.
But under Shackleton’s leadership, the expedition did not despair. They salvaged the ship’s lifeboats and some of the supplies. When the weather warmed again, they rowed through the deadly currents and ice floes, finally arriving on the continent in April 1916.
Joyful that they had survived, the men also contemplated that they had no way off the continent and not enough supplies to complete their expedition across it.
