Michael Strogoff
While the physical description of Siberia is accurate, the Tartar rebellion described was not a rebellion and the strength as well as the geographical reach of the Tartars is highly exaggerated. After the Khanates had been gradually pushed back further South earlier in the 19th century, in 1865-68 Russia had conquered the weakened Central Asian Uzbek Khanates of Kokand and Bukhhara, both located much further South than the cities through which Strogoff travelled in the novel. While there thus had been war between Russia and "Tartars" a few years before Jules Verne wrote "Michael Strogoff", no Tartar Khan at the time was in a position to act as Feofar is described as doing; depicting late 19th Century Tartars as able to face Russians on anything resembling equal terms is an anachronism.
