The lost ship of Ernest Shackleton has been found 106 years after it sank.

The wooden ship Endurance has been found underwater in the Weddell Sea.

Mensun Bound, a maritime archaeologist and director of exploration on the expedition, said that the find was a milestone in polar history.

This is the best wooden wreck I have ever seen. It is in a brilliant state of preservation and upright. You can see it across the stern.

As World War I began in 1914, the British explorer Shackleton set out to go to the South Pole. The plan was for Shackleton to take 27 men on two ships and explore two routes by sledge across the ice. In January 1915, the Endurance became trapped in ice off the coast of Antarctica.

The men lived on the ship for a long time, but the ice began to crush it. The order to abandon the Endurance was given by Shackleton. The men were told to get no more than two pounds of gear from the ship, as much of the supplies had already been cut off due to the broken timbers. The Endurance sank into the sea in 1915.

The crew made a new camp on an ice floe, and their ambition to cross the ocean dissipated. The mission was now one of survival, a saga that would stretch into August 1916 before all the men were rescued.

The expedition to find the Endurance will leave Cape Town, South Africa, on February 5.

John Shears, the expedition leader, said the hunt for Endurance was probably the most challenging wreck search ever done.

The sunken ship was found with the help of the expedition. The ship was located about 4 miles south of where Frank Worsley had noted it in 1915.

The team used an underwater vehicle with a camera to confirm what they had found.

Shears said that it can only be one ship. I think we are the fourth ship to ever get into this place. It is called Endurance. It can be nothing else.

Shears was amazed by the condition of the vessel, which has hardly anything living on it and some of the original paint is intact.

The wreck is protected as a monument under the treaty. The Endurance will not be disturbed because it is being filmed and surveyed.

The exploration director said that the discovery is not only about the past, but also about bringing the story of Shackleton and Endurance to the next generation.

Bound said that they hope the discovery will engage young people and inspire them with the spirit and courage of those who sailed the Endurance.
