The Battle of Kolno was fought on 10 July 1794 during the Koà Âciuszko Uprising, between PolishâÂÂLithuanian insurgents, led by Colonel Walenty Kwaà Âniewski, and Prussian Army led by General Heinrich Johann Günther. It took place in Kolno, in PolishâÂÂLithuanian Commonwealth, now part of Poland, and ended without definitive victors, with both sides retreating.
Prussian General Heinrich Johann Günther, carrying about 750 troops, marched from Kozioà  near the Pisa river to Szczuczyn, when on 9 July, he found the presence of PolishâÂÂLithuanian insurgents, led by colonel Walenty Kwaà Âniewski, stationed in Kolno. Günther decided to strike it by surprise. At 1 am, the Prussians attacked the town, which contained around 1,450 PolishâÂÂLithuanian soldiers.
The Prussians struck at the insurgents positions through the dikes on the à Âabna river. The attack collapsed under the PolishâÂÂLithuanian infantry fire. At around 10 am, Günther ordered the battle to be stopped and all captured prisoners of war executed, after which he withdrew near Pisz. Kwaà Âniewski's group, on the other hand, withdrew to Borkowo.
