Endurance was the three-masted barquentine in which Sir Ernest Shackleton sailed for the Antarctic on the 1914 Imperial Trans-Antarctic Expedition. She was launched in 1912 from Sandefjord in Norway and was crushed by ice, causing it to sink, three years later in the Weddell Sea off Antarctica.

Design and construction[edit]

Designed by Ole Aanderud Larsen, Endurance was built at the Framnæs shipyard in Sandefjord, Norway and fully completed on December 17, 1912. She was built under the supervision of master wood shipbuilder Christian Jacobsen, who was renowned for insisting that all men in his employment were not just skilled shipwrights, but also be experienced in seafaring aboard whaling or sealing ships. Every detail of its construction had been scrupulously planned to ensure maximum durability, for example every joint and every fitting cross-braced each other for maximum strength.

The ship was launched on December 17, 1912 and was initially christened Polaris (eponymous with Polaris, the North Star). She was 144 feet (44 m) long, with a 25 feet (7.6 m) beam and measured 348 tons gross.[1] Though her black hull looked from the outside like that of any other vessel of a comparable size, it was not. She was designed for polar conditions with a very sturdy construction. Her keel members were four pieces of solid oak, one above the other, adding up to a thickness of 85 inches (2,200 mm), while its sides were between 30 inches (760 mm) and 18 inches (460 mm) thick, with twice as many frames as normal and the frames being of double thickness. She was built of planks of oak and Norwegian fir up to 30 inches (760 mm) thick, sheathed in greenheart, a notably strong and heavy wood. The bow, which would meet the ice head-on, had been given special attention. Each timber had been made from a single oak tree chosen for its shape so that its natural shape followed the curve of the ship's design. When put together, these pieces had a thickness of 52 inches (1,300 mm).

Of her three masts, the forward one was square-rigged, while the after two carried fore and aft sails, like a schooner. As well as sails, Endurance had a 350 horsepower (260 kW) coal-fired steam engine capable of speeds up to 10.2 knots (18.9 km/h; 11.7 mph).

By the time of launch on December 17, 1912, Endurance was perhaps the strongest wooden ship ever built, with the possible exception of Fram, the vessel used by Fridtjof Nansen and later by Roald Amundsen. However, there was one major difference between the ships. Fram was bowl-bottomed, which meant that if the ice closed in against her it would be squeezed up and out and not be subject to the pressure of the ice compressing around her. But since Endurance was designed to operate in relatively loose pack ice she was not constructed so as to rise out of pressure to any great extent.

Ownership[edit]

As Endurance was built for Adrien de Gerlache and Lars Christensen, they intended to use her for polar cruises for tourists to hunt polar bears. Financial problems leading to de Gerlache pulling out of their partnership meant that Christensen was happy to sell the boat to Ernest Shackleton for GB£11,600 (approx US$67,000), less than cost. He is reported to have said he was happy to take the loss in order to further the plans of an explorer of Shackleton's stature [1]. After Shackleton purchased the ship, she was rechristened "Endurance" after the Shackleton family motto "Fortitudine vincimus" (By endurance we conquer).

In the previous 16 years nearly two dozen wooden vessels had braved the icy seas of the far south. All had returned home but the Aurora. Lloyd's of London and the Indemnity Marine Assurance Company had underwritten her hull, machinery and equipment for £15,000. Just before she sailed, The Times of London had reported that "Hitherto the insurance of vessels taking part in Antarctic exploration has ceased at the last port touched, and the Endurance will be the first vessel to be insured in the ice zone."

Insurance gives little warmth to a freezing man. Nature underwrites the underwriters by behaving with certain predictability. In Antarctica, nature contains forces that Lloyd's of London and the Endurance crew could only partially understand and never control. The Times had praised the Endurance as "built specially for work in Polar seas," adding that "in an ice-coated sea there can be no turbulent waves which are the causes of so many disasters in warmer zones."[2]

Final voyage[edit]

Shackleton sailed with Endurance from Plymouth, England on August 6, 1914 and set course for Buenos Aires, Argentina. This was Endurance's first major voyage following its completion and amounted to a shakedown voyage. The trip across the Atlantic took more than two months. Built for the ice, its hull was considered by many of its crew too rounded for the open ocean.

On October 26, 1914 Endurance sailed from Buenos Aires to what would be her last port of call, the whaling station at Grytviken on the island of South Georgia, arriving on November 5. She left Grytviken on December 5, 1914 heading for the southern regions of the Weddell Sea.

Two days after leaving from South Georgia, Endurance encountered polar pack ice and progress slowed down. For weeks Endurance worked its way through the pack, averaging less than 30 miles (48 km) per day. By January 15, 1915 Endurance was within 200 miles (320 km) of her destination, Vahsel Bay. However by the following day heavy pack ice was sighted in the morning and in the afternoon a gale developed. Under these conditions it was soon evident progress could not be made, and Endurance took shelter under the lee of a large grounded berg. During the next two days Endurance moved back and forth under the sheltering protection of the berg.

On January 18 the gale began to moderate and Endurance set the topsail with the engine at slow. The pack had blown away. Progress was made slowly until hours later Endurance encountered the pack once more. It was decided to move forward and work through the pack, and at 5pm Endurance entered it. However it was noticed that this ice was different from what had been encountered before. The ship was soon amongst thick but soft brash ice. The ship became beset. The gale now increased in intensity and kept blowing for another six days from a northerly direction towards land. By January 24, the wind had completely compressed the ice in the whole Weddell Sea against the land. Endurance was icebound. All that could be done was to wait for a southerly gale that would start pushing, decompressing and opening the ice in the other direction. Instead the days passed and the pack remained unchanged.

Endurance drifted for months beset in the ice in the Weddell Sea. The changing conditions of the Antarctic spring brought such pressure that broke the hull of Endurance over the period from October 27, 1915, causing flooding of interior spaces. On the morning of November 21, 1915, the Endurance's bow began to sink under the ice and thus she had to be abandoned.[3] Shackleton and five others took one of the ship's lifeboats, the James Caird, and sailed to South Georgia to obtain rescue for the rest of the crew.

Crew[edit]

The crew of Endurance in her final voyage was made up of the 28 men listed below:[4]

Nationalities. All the crew were born and resident in England before the expedition, except for the following:

  • Shackleton. Born in Ireland (then part of the United Kingdom), lived in England from early childhood.
  • Worsley. New Zealander.
  • Greenstreet. New Zealander.
  • Crean. Irish.
  • Macklin. Born in India, resident in England from childhood.
  • McIlroy. Born Northern Ireland, moved to England as a teenager.
  • Wordie. Scottish.
  • Hurley. Australian.
  • Clark. Scottish.
  • McNish. Scottish.
  • Bakewell. American, may have claimed to be Canadian when he applied to join the Imperial expedition in Buenos Aires.
  • McCarthy. Irish.
  • Blackborrow. Welsh.

Blackborrow was originally refused a post aboard the vessel due to his young age and inexperience and decided to stow away, helped to sneak aboard by William Bakewell, a friend of his, and Walter How. When he was found Shackleton decided to make him a steward rather than leave him ashore at South Georgia. Blackborrow eventually proved his worth, earning the Bronze Polar Medal, and the honour of becoming the first human being ever to set foot on Elephant Island. His name is also the matter of some debate—it is sometimes spelled Percy, or Blackboro, or in other ways.

Supposed advertisement[edit]

It is often said that Shackleton placed an advertisement in a newspaper reading:

Men wanted for hazardous journey. Small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honour and recognition in case of success. Sir Ernest Shackleton.[5]

No trace of the supposed advertisement has come to light.

Modern history[edit]

Alfred Lansing wrote a book titled Endurance: Shackleton's Incredible Voyage about the ordeal that Shackleton and his men endured aboard the ship. It became a bestseller when first published in 1959.

Two Antarctic patrol ships of the British Royal Navy have been named Endurance in honour of Shackleton's ship. The first HMS Endurance, launched in May 1956 and awarded pennant number A171 sometime later, acted as an ice patrol and hydrographic survey ship until 1986. The second HMS Endurance was bought from Norway in 1992 where she was named MV Polar Circle. She is not currently (2012) in commission.

The wreck[edit]

In 1998 wreckage found at Stinker Point on the south western side of Elephant Island was incorrectly identified as flotsam from the ship. That in fact belonged to the 1877 wreck of the Connecticut sealing ship Charles Shearer.[6] In 2001 wreck hunter David Mearns unsuccessfully planned an expedition to find the wreck of the Endurance.[7] By 2003 two rival groups were making plans for an expedition to find the wreck,[7][8] however no expedition was actually mounted. In 2010 Mearns announced a new plan to search for the wreck. The plan is sponsored by the National Geographic Society but is subject to finding sponsorship for the balance of the U.S. $10 million estimated cost.[9][10] A 2013 study by Dr Adrian Glover of the Natural History Museum, London suggests the Antarctic Circumpolar Current could preserve the wreck on the seabed by keeping wood-boring "ship worms" away.[11]

Popular Culture[edit]

The 2013 videogame Tomb Raider features a ship named Endurance, which also first sailed from Plymouth.
