Abbé huc's Travels in Tartary, Tibet and China, during the years 1844–5–6, has long since become one of the world's great travel classics. For some decades after its publication, however, it was read with the utmost scepticism. Foremost among the sceptics, and the book's chief detractor, was the Russian explorer, Prjevalsky, whose vindictive attempts to disprove Huc's statements caused many people to doubt that he and Father Gabet had ever entered Tibet. It was some forty years after the book first appeared before Huc found a champion in the American traveller, W. W. Rockhill, who in writing of his own expeditions, quoted the Abbé frequently, and stated his faith in the earlier traveller's observations. Shortly after this, Henri, Due d'Orleans, wrote a book protesting the widespread lack of belief in Huc's narrative. Refuting Prjevalsky's major charges point by point, he made it clear that the Russian's motive for casting slurs on the Frenchmen was largely due to his jealousy at their having gone so far into the interior, where he himself had been unable to go. Finally, in 1900, Henri Cordier published some diplomatic correspondence between Ch'i-ying, the governor-general at Canton, and the French consul, M. de Bécour, which discussed the expulsion of the two Lazarist fathers from Lhasa, leaving no doubt that they had been there.
