Shackleton was a national hero in England when he began his 3rd Antarctic trip. He had been knighted for his attempt to reach the South Pole between 1907 and 1909 after coming within 100 miles of his goal.
It will be convenient to state here briefly some of the considerations that weighed with me at that time and in the weeks that followed. I knew that the ice had come far north that season and, after listening to the suggestions of the whaling captains, had decided to steer to the South Sandwich Group, round Ultima Thule, and work as far to the eastward as the fifteenth meridian west longitude before pushing south. The whalers emphasized the difficulty of getting through the ice in the neighbourhood of the South Sandwich Group. They told me they had often seen the floes come right up to the group in the summer-time, and they thought the Expedition would have to push through heavy pack in order to reach the Weddell Sea. Probably the best time to get into the Weddell Sea would be the end of February or the beginning of March. The whalers had gone right round the South Sandwich Group and they were familiar with the conditions. The predictions they made induced me to take the deck-load of coal, for if we had to fight our way through to Coats’ Land we would need every ton of fuel the ship could carry.
I hoped that by first moving to the east as far as the fifteenth meridian west we would be able to go south through looser ice, pick up Coats’ Land and finally reach Vahsel Bay, where Filchner made his attempt at landing in 1912. Two considerations were occupying my mind at this juncture. I was anxious for certain reasons to winter the Endurance in the Weddell Sea, but the difficulty of finding a safe harbour might be very great. If no safe harbour could be found, the ship must winter at South Georgia. It seemed to me hopeless now to think of making the journey across the continent in the first summer, as the season was far advanced and the ice conditions were likely to prove unfavourable. In view of the possibility of wintering the ship in the ice, we took extra clothing from the stores at the various stations in South Georgia.
