After failing to be the first to reach the South Pole by only 97 miles in 1909, Shackleton set out to be the first to cross the Antarctic continent via the pole. The expedition met disastrous results when its ship became trapped and ultimately crushed in the ice pack.
Shackleton's attempt to become the first to traverse the Antarctic continent via the pole was a direct consequence of his previous failure to be the first to reach the South Pole by 97 miles in 1909. The expedition's disastrous outcome, involving the ship being trapped and crushed by the ice pack, resulted from this ambition.
