In contrast to the misfortunes of Scott's team, Amundsen's trek proved relatively smooth and uneventful. In 1918, an expedition Amundsen began with a new ship, , lasted until 1925. "Maud" was carefully navigated through the ice west to east through the Northeast Passage. With him on this expedition were Oscar Wisting and Helmer Hanssen, both of whom had been part of the team to reach the South Pole. In addition, Henrik Lindstrøm was included as a cook. He suffered a stroke and was so physically reduced that he could not participate. The goal of the expedition was to explore the unknown areas of the Arctic Ocean, strongly inspired by Fridtjof Nansen's earlier expedition with "Fram". The plan was to sail along the coast of Siberia and go into the ice farther to the north and east than Nansen had. In contrast to Amundsen's earlier expeditions, this was expected to yield more material for academic research, and he carried the geophysicist Harald Sverdrup on board. The voyage was to the northeasterly direction over the Kara Sea. Amundsen planned to freeze the "Maud" into the polar ice cap and drift towards the North Poleas Nansen had done with the "Fram"and he did so off Cape Chelyuskin. But, the ice became so thick that the ship was unable to break free, although it was designed for such a journey in heavy ice. In September 1919, the crew got the ship loose from the ice, but it froze again after eleven days somewhere between the New Siberian Islands and Wrangel Island. During this time, Amundsen suffered a broken arm and was attacked by polar bears. As a result, he participated little in the work outdoors, such as sleigh rides and hunting. He, Hanssen, and Wisting, along with two other men, embarked on an expedition by dog sled to Nome, Alaska, more than away. But they found that the ice was not frozen solid in the Bering Strait, and it could not be crossed. They sent a telegram from Anadyr to signal their location. After two winters frozen in the ice, without having achieved the goal of drifting over the North Pole, Amundsen decided to go to Nome to repair the ship and buy provisions. Several of the crew ashore there, including Hanssen, did not return on time to the ship. Amundsen considered Hanssen to be in breach of contract, and dismissed him from the crew.
