Roald Amundsenthe ObservatoryINTJ

On the morning of 17 September 1911, at breakfast in a wooden hut on the Antarctic ice, Roald Amundsen asked two of his men why they had come in so late the night before. He was 39, and he was racing Robert Falcon Scott to the South Pole.

Amundsen planned like few people before or since. He had decided on the Pole in secret in 1909 and told his crew only when the ship reached Madeira a year later. He laid depots, marked them with flags and trusted his dogs. Every piece of the plan was worked out alone, and complete before anyone saw it.

That September he started too early. On the 8th, eight men left Framheim, their hut at the Bay of Whales. Within days the cold fell below −50 °C, and he turned back rather than risk men and dogs. It was the right call.

The return was not. On 16 September, about 75 kilometers out, he pushed on for the hut without waiting, and the party broke apart. The first sledges arrived in the afternoon. The last two men, Kristian Prestrud and Hjalmar Johansen, came in at half past midnight. Prestrud had been struggling, and Johansen had stayed with him through the dark and the cold.

Johansen was 44, the most experienced polar traveler in the hut. He had marched with Fridtjof Nansen toward the North Pole. At breakfast, in front of everyone, he said what he thought of the dash. By one account his words were: “I don't call it an expedition. It's panic.”

Amundsen's diary records what he minded most.

He decided alone. The bull had to be taken by the horns, he wrote, and an example made at once. Johansen was cut from the Pole party and ordered, in writing, to go east to King Edward VII Land under Prestrud, the younger man he had just brought home.

Observatories may recognize the move from the inside. You do the thinking privately and thoroughly, and a public challenge to the finished plan feels like a danger to everyone. Amundsen was right that a split party on the polar trek could cost lives.

The plan worked almost perfectly. Five men left on 20 October, and on 14 December 1911 they reached the South Pole. All five came home. Scott's party, which arrived after them, died on the way back.

Johansen was left out of the glory. At Hobart in March 1912, Amundsen dismissed him from the expedition, and the story Amundsen told left him out. On 3 January 1913, back in Kristiania, Johansen took his own life. No one can say why.

Amundsen could see a route to the bottom of the world years ahead. He missed the man across the table, who had just done the plan's hardest work in the dark.
