On the 30 September 1708 the eight Russians captured at Koporye two days earlier were interrogated. A short summary of the result:
The first one said he was a corporal in Col. Hupowitz regiment of Cossacks, 1,000 men strong. However, only 400 were present at Koporye and they had arrived from Pechory eight days earlier. They were not the only ones to arrive, a detachment of dragoons under the command of Lt. Col. Stepanov (6 companies of about 100 men each) had also come from Pechory. These detachments were at Koporye under the command of Brigadier Frazer, who had six regiments at his disposal. There was a garrison of 700 in Koporye itself, but these had not taken part in the battle.
The next two prisoners belonged to the Tobolsk dragoon regiment. They had deserted from their unit, which was under the command of Lt. Col. "Wasili Czatzeoff". The regiment consisted of six companies. They had arrived from Livonia about six weeks earlier. There were 700 men in the garrison at Koporye. When the Swedes had attacked there were six Russian regiments.
The last five prisoners were from Monastyrev's dragoons (2), Manstein's dragoons (2) and "Pladur's" battalion (1). According to them there hade been five dragoon regiments and one Cossack regiment at Koporye. There were six Lt. Colonels and six Majors. The regiments were:
Monastyrev's dragoons (900 men), Schauenburg's dragoons (800), Jarsen's (?) dragoons (500), Alontkof's (?) dragoons (400), Tobolsk dragoons (600) and Bachmetov's Cossacks (600).
(It should be emphasized that this is a summary of the testimonies given by these prisoners - or rather how the Swedish interrogators interpreted their remarks).
