Dvinsky governor Alexey Petrovich Prozorovsky was in great worries. By decree of Tsar Peter Alekseevich, who received news from loyal people that the Swedes were going to attack Arkhangelsk and close the gates of the Russian state to Europe, the governor was ordered to immediately take measures so that the enemy, if he attacked the Dvina, would receive a decisive and well-organized rebuff. The king was not worried in vain. The Arkhangelsk port has become a busy point of trade between Russia and foreign countries. During navigation, foreign ships came here under the Dutch, English, Danish, Swedish and French flags.
