In the series, Amundsen visits Dr Frederick Cook in Leavenworth Prison shortly after the publication of Scott's journal. In reality, the meeting took place more than a decade later, in 1926, when Cook was serving a sentence for his part in an alleged oil fraud.
On his return from the South Pole at 'Framheim,' Amundsen learns that the credit for reaching the North Pole has been taken away from Dr Frederick Cook and given instead to Peary. In reality, Amundsen was well aware of the controversy *before* his departure for Antarctica, and to avoid any question that he had not reached the true South Pole due to faulty navigation, staked out an area of ten miles around what he believed to be the Pole itself.
