On 13/23 of March 1702 a Swedish detachment under colonel of Adelsfanan i Sverige och Finland Alexander Hummerhielm (link) marched from Kowno to Jezno (modern Lithuanian Jieznas) to gather supplies & take artillery & ammunition from Jezno’s castle. It composed of 130 reitars of Ostgota Ryttare in 3 coys under Rittmeisters Otto Heinrich Schulman, Anders Blumenschold & Erik Gyllenbreider. Hummerhielm was also backed by a detachment under Captain of Livgardet till fot Gustaf Henrik Siegroth with 80 foot (30 from Livgardet till fot & 50 from Upplands). On 23rd’s evening Hummerhielm came at Dersunisjki. Where he was informed that a strong Lithuanian detachment under Michal Wisniowecki was somewhere close to him, but decided to stay there for a night.
Lithuanians attacked early in the morning. Michal Wisniowecki had 12 choragwies of Pancerni & Wallachians & 10 cannons, totaled about 1,000-1,500 (not 8,000 as in a Swedish relation). Hummerhielm decided to meet the enemy in a field with 100 reiters, the rest stayed at Dersunisjki as a reserve. Brave Swedish attack was repelled, & superior Lithuanians easily surrounded them. After a severe fight Lithuanians captured Hummerhielm himself, one leutnant & about 40 other ranks. About 90 Swedes (incl. Major Hans Fredrik Siegroth & 3 Rittmeisters) were killed. Only 7 Swedes could escaped from the village. Captain Siegroth with 20 foot tried to help Swedish cavalry & cover its retreat, but was surrounded on a mill near Dersunisjki. He agreed to capitulate on a terms of free passage. He lost 6 soldiers killed & 9 wounded, plus 3 servants.
Hummerhielm was sent to Wisniowecki’s Zaber castle, where was imprisoned till 1704, when Swedes took it.
