In the first place, the Cossacks ascended, for four days, the course of the Tchusovaya, rapid and sown with rocks, as far as the chain of the Ural Mountains. The two following days, in the shadow of the masses of stone with which the interior of these mountains is covered, they reached, by means of the river Serebrennaia, the passage called the "Route of Siberia." There they stopped, and, ignorant of what might next happen to them, they constructed for their safety a kind of redoubt to which they gave the name of _kokui_. They had so far found only deserts and a small number of inhabitants. Then they moved, towing their small crafts as far as the river of Iaravle. These places are, even to this day, marked by the monuments of Iermak; rocks, caverns, remains of fortifications, bear his name. It is asserted that the big boats abandoned by him between the Serebrennaia and the Barantcha are not, in our time, entirely decayed, and that lofty trees shade their ruins, half reduced to dust. By the Iaravle and the Taghil the Cossacks, reaching the Tura, which waters one of the provinces of the empire of Siberia, for the first time drew the sword of conquerors. At the place where the city of Turinsk now stands there then existed a little town, the domain of the prince Yepantcha. He commanded a large number of Tartars and Vogulitches, and received these audacious strangers with a hail of arrows, shot from the banks of the river, at the place where is seen the present village of Usseninovo; but, frightened by a discharge of artillery, he forthwith took flight. Iermak caused the town to be destroyed, of which the name alone remains, for the residents still give to Turinsk the name "Town of Yepantcha." The camps and villages situated along the Tura were devastated. The Cossack leaders having taken, at the mouth of the Tavda, an officer of Kutchum's, named Tausak, he, desirous of saving his life, communicated to them important information regarding the country. As the price of his frankness, his liberty was given him, and he hastened to announce to his master that the predictions of the soothsayers of Siberia were being realized, for according to some accounts these pretended sorcerers had for a long time proclaimed the near and inevitable downfall of this state by an invasion of Christians. Tausak spoke of the Cossacks as wonderful men and invincible heroes, lancing fire and thunder which penetrate through the cuirasses. Nevertheless, Kutchum, although deprived of sight, had a strong soul. He made ready to defend his country and his faith with courage. He at once gathered all his subjects, made his nephew Mahmetkul enter the campaign at the head of a large force of cavalry, and he himself threw up fortifications on the bank of the Irtisch, at the foot of the Tchuvache mountain, thus closing to the Cossacks the road to Isker.
