During last week I had a look at some of the Swedish sources for the Ingrian campaign of 1708, including Lybecker's report about the encounter near Koporye fortress on 28 September 1708. A short summary of what he claims:
While his army for three days was busy unloading and distributing provisions brought by sea a report arrived. This indicated that the Russians were moving their cavalry from Duderhof to Koporye in order to cut off the Swedish army. Upon receiving this news Lybecker detached a cavalry force of 1,800 men under the command of colonels Ramsay and Armfelt. They were instructed to observe the enemy and attack if the latter made a stand. Upon reaching a nearby village the Swedes were told that a Russian force of about 100 cavalry and 100 infantry had been there about an hour earlier and that the Russian force had taken up a position near Koporye. Ramsay and Armfelt discussed the situation with several officers in their detachment and decided to advance towards Koporye. Their approach was made up a very steep hill towards a large open field which reached beyond the fortress. The Russians were drawn up in two lines on this field, at a distance of a few musket shots from the fortress itself. Some additional squadrons were placed behind the two lines. As the Swedish force approached and took up position Armfelt assumed command of the right flank and Ramsay of the left. Orders were given to abstain from firing and attack with the sword only. As the Swedish attack started the Russians advanced as well. Cossacks and a force of boyars which were positioned in front of the Russian lines opened fire and the Cossacks attacked the Swedish left. Major de la Barre counterattacked with some squadrons and hit the flank of the Cossacks and drove them off. The Russian line opened fire and tried to regroup, but the strong Swedish assault forced both lines to retreat and the Russians started streaming backwards. As they were doing this they came upon a very deep ravine which crossed the field and went into the moat. Many Russians were driven down into the ravine and got stuck in the mud, where they were picked off by Swedish fire. Major Danielsson and some of his men jumped off their horses and went down into the ravine where they killed a large number of Russians with the sword. Another group were killed in similar fashion by Col. Ramsay very near the moat.
The garrison in Koporye tried to support the Russians with artillery fire and another force opened fire with muskets from a dry moat on the right as well as from a large house on the left. This did not stop the Swedes, who again attacked and pursued the fleeing Russians for several kilometres until they reached a small river which the Russians were forced to swim across.
Those who fled towards Koporye fortress were pursued by Lt. Col. Brakel with seven companies all the way to the drawbridge, forcing some Russians to jump into the moat to save themselves. The Russian fire from the fortress was intense but very inefficient, only killing one officer and wounding another. When the Swedes fell back from the drawbridge the Russians in the fortress counterattacked with both infantry and cavalry (with a force estimated to have been about 1,200). Col. Armfelt counterattacked and drove them back, but the Russians got reinforcements and attacked again. Eventually Armfelt decided to retreat and this was conducted very skillfully. His force lost about 50 men in total and the rest of the Swedish units lost another 20. The Russian losses were estimated as having been about 600. The enemy's baggage was captured. Among Brigadier Fraser's belongings several letters were found and they contained much valuable information. According to the prisoners Fraser commanded 5 dragoon regiments, 1 regiment of Cossacks and 1 unit of "selected Boyars". The Russians had left their colours in the fortress, so none were taken during the fight.
