The reason for the victory of Russian weapons in Siberia is often explained very simply. "The Conquest of Siberia" is sometimes described as a "barbaric destruction," for fear of firing guns in battle to distance themselves from the Cossacks, and therefore can not cause them serious harm
Such representations strongly disagree with that fact. The Russian enemy in Siberia is not in the mainstream either without defense or cowardice. Most Siberian societies of the seventeenth century are at a stage of development characterized by increased militancy and combat activity (so-called "military democracy" periods)
"People are fighters, they are cruel in fights," "fast and great archers" - so the Cossacks people talk about their opponents.
Firearms, of course, make important gains (not much variety, much greater destructive forces), but because of these weapon design defects in the XVI-XVII century and Russian "mololyudstva", "against fire" is often only allowed to maintain a certain parity party. In any case, the military superiority of the Cossacks in Siberia at a time when he rarely because of permanent and decisive "firing fire".
