The second part of the sensational story of the disappearance of the expedition of the Russian Geographical Society.

The task of the expedition is to cross the watershed of the Ob and Yenisei at a point where there are no settlements, but it is here that a ridge of islands passes through the swamps connecting the upper reaches of the tributaries of the two great Siberian rivers.
According to our theory, it is along this ridge the "ridge" as local Old Believers call this natural object that the Tunguska nomadic trail passes, it was this path that the militant Tungus detachments used to try to defeat their enemy a small garrison of Russian pioneers who put up a wooden fortress in the upper reaches of the Keti.
In the spring of 1609, news appeared in the Upper Tibetan taiga about a warlike people who attacked the Yasash Ostyaks and threatened to attack the Russian fortress, the nearest fortress of Narym, was two months away at the mouth of the Keti. In Russia at this time there was a Turmoil and there was no help to wait from where
Therefore, voivode Elizarov, without waiting for an answer to his disturbing letters, secretly for Moscow, moved the prison to the west, to the mouth of the Orlovka. So it turned out to close the exit of the Tungus to the Ket, which crossed the huge watershed swamp not by small rivers and portages, but by pine forests to "whitecollar workers" giving food to their transport deer. It is the forests that cover the swamp islands, and it is there that we are trying to find traces of these formidable conquerors.
If we are lucky, we will confirm our theory about the transfer of the Ket prison as a response to the threat of an attack by the Tungus...
