In this article the author isolates an anecdote from Roland Huntford's account of the Scott and Amundsen expeditions’ meeting on 4 February 1911 at Framheim, the Norwegian base in the Bay of Whales. In this anecdote, Lieutenant Victor Campbell allegedly told Roald Amundsen that a British motor sledge was ‘already on terra firma’, which consequently led Amundsen to worry that a British motor-sledge had already travelled across the Great Ice Barrier to reach the Beardmore Glacier. The author demonstrates the primary evidence that indicates that this anecdote is unrealistic: Amundsen's journal further indicates that he did not consider Scott's vehicles a threat. This ‘terra firma’ myth has skewed our modern understanding of events, ascribing to Amundsen an erroneous motivation (a supposed fear of the British motor sledges) to explain and excuse his too-early start for the south pole in September 1911, which was an error that nearly led to a Norwegian death (that of Lieutenant Kristian Prestrud). In reality, fear of Scott's motor sledges was not the reason for Amundsen's ‘false start’. This article concludes with a discussion on the hazards of attributing ‘hidden motivations’ to historical figures without citation of primary evidence, and recommends that Huntford include clearly-cited references and endnotes for the next edition of his joint biography of Scott and Amundsen, in keeping with modern standards of scholarship.
