There happened several slight engagements in the course of this year, between the Russians and Swedes, in which the latter did not always prove superior; and even in those where they had the advantage, the Russians improved in the art of war. In short, in little more than twelve months after the battle of Narva, the czar's troops were so well disciplined, that they defeated one of the best generals belonging to the king of Sweden. Peter was then at Pleskow, from whence he detached numerous bodies of troops, on all sides, to attack the Swedes; who were now defeated by a native of Russia, and not a foreigner. His general, Sheremeto, by a skilful manoeuvre, beat up the quarters of the Swedish general, Slipenbak, in several places, near Derpt, on the frontiers of Livonia; and at last obtained a victory over that officer himself. (Jan. 11, 1702.) And now, for the first time, the Russians took from the Swedes four of their colours; which was thought a considerable number. May.] The lakes Peipus and Ladoga were for some time afterwards the theatres of sea-fights between the Russians and Swedes; in which the latter had the same advantages as by land: namely, that of discipline and long practice; but the Russians had some few successes with their half gallies, at the lake Peipus, and the field-marshal Sheremeto took a Swedish frigate. By means of this lake, the czar kept Livonia and Esthonia in continual alarms; his gallies frequently landed several regiments in those provinces; who reimbarked whenever they failed of success, or else pursued their advantage: the Swedes were twice beaten in the neighbourhood of Derpt, (June, July,) while they were victorious every where else. In all these actions the Russians were always superior in number; for this reason, Charles XII. who was so successful in every other place, gave himself little concern about these trifling advantages gained by the czar: but he should have considered, that these numerous forces of his rival were every day growing more accustomed to the business of fighting, and might soon become formidable to himself. While both parties were thus engaged, by sea and land, in Livonia, Ingria, and Esthonia, the czar is informed that a Swedish fleet had set sail, in order to destroy Archangel; upon which he immediately marched thither, and every one was astonished to hear of him on the coasts of the Frozen Sea, when he was thought to be at Moscow. He put the town into a posture of defence, prevented the intended descent, drew the plan of a citadel, called the New Dwina, laid the first stone, and then returned to Moscow, and from thence to the seat of war.
