From this time onward difficulties confronted them. They were in a region of mountains, precipices, ravines, and torrents. One dangerous river they swam, but, instead of keeping on due south, the difficulties of the way induced them to change their course to the west, alarmed, probably, by the vast snowy peaks of the Tangnou Mountains in the distance, though if they had passed these all danger from Siberia would have been at an end. As it was, after more than three weeks of wandering, the nature of the country forced them towards the northwest, until they came upon the eastern shore of the Altin-Kool Lake. Here was their final chance. Had they followed the lake southerly they might still have reached a place of safety. But ill fortune brought them upon it at a point where it seemed easiest to round it on the north, and they passed on, hoping soon to reach its western shores. But the Bea, the impassable torrent that flows from the lake, forced them again many miles northward in search of a ford, and into a locality from which their chance of escape was greatly reduced. More than two months had passed since they left the mines, and the poor wanderers were still in the vast Siberian prison, from which, if they had known the country, they might now have been far away. The region they had reached was thinly inhabited by Kalmuck Tartars, and they finally entered a village of this people, with whose inhabitants they unluckily got into a broil, ending in a battle, in which several Kalmucks were killed and the village burned. To this event was due the terrifying news that reached Barnaoul, the alarm being carried to a Cossack fort whose commandant was drunk at the time and sent out a series of exaggerated reports. As for the fugitives, they had in effect signed their death-warrant by their conflict with the Kalmucks. The news spread from tribe to tribe, and when the real number of the fugitives was learned the tribesmen entered savagely into pursuit, determined to obtain revenge for their slain kinsmen. The Circassians were wandering in an unknown country. The Kalmucks knew every inch of the ground. Scouts followed the fugitives, and after them came well-mounted hunters, who rapidly closed upon the trail, being on the evening of the third day but three miles away. The Circassians had crossed the Bea and turned to the south, but here they found themselves in an almost impassable group of snow-clad mountains. On they pushed, deeper and deeper into the chain, still closely pursued, the Kalmucks so managing the pursuit as to drive them into a pathless region of the hills. This accomplished, they came on leisurely, knowing that they had their prey safe.
