A small Polish force (between 200 and 500 men) surprised a weakly guarded Swedish-Brandenburg cavalry camp at Lubrze in Greater Poland, near Śrem and Środa Wielkopolska, and 47 km south-east of the voivodeship capital of Poznań.

Throughout the night, fighting Polish soldiers decimated the Swedish-Brandenburg division (source vary from 800 to 2000 strong),both in the village and on the banks of a small stream where the defenders took flight.

Rudawski states that the Swedes suffered following losses in officers: Majors Peter, Jan Otto de Walh, Hejder from the Saxon regiment.

It forced the nominal possessor of Greater Poland, the Prussian-Brandenburg Elector, to reroute a sizable Prussian division under Derflinger, also marching towards Kalisz, to withdraw north to Toruń, after leaving commands at Poznań and Miedzyrzecz.

Devoid of any hope of the relief forces, the besieged Swedish garrison of Kalisz surrendered to the Polish army on November 8, 1656.
