[8] After a series of successes for the Russian forces, with an even more successful Swedish invasion of Polish–Lithuanian Commonwealth, the Russian tsar decided that total defeat of the Commonwealth and Swedish victory leading to major strengthening of Sweden (a threat to Russia) would not be in the best interests of Russia.
