Charles X Gustav of Sweden was willing to allow her to cross over to her husband but she refused this courtesy, relying instead on her regimentarz Stefan Czarnieckki, stationed with his division at Piotrków Trybunalski.

Polish cavalry companies settled in the surrounding countryside, occupying villages and being separated one from another by distance, need for fodder and food, and winter snows.

His command attacked immediately the following Polish formations: pułk of prince Konstanty Wiśniowiecki, banners of Jan Sobieski and Koniecpolski.

Ar [clarification needed] some moment heavy night fighting reached the queen's wagon train and she had to seek shelter, perhaps in the town itself.

And perhaps other Polish army divisions came to give more coordinated response to the Swedish vanguard onslaught, and as the break of dawn of January 3, 1657 was slowly approaching.

Perhaps at that moment quite victorious Swedish commander must have realized that he had stepped into the hornets' nest and begun hasty retreat - according to des Noyers bride abattue.

The surprise night attack came to cost him dearly, as Czarniecki division had come to pursue him, and Swedish command never turned their head to face their pursuers, and his retreat turned into run-and-chase battle, and the Swedish cavalry became Polish prey, thus sustaining 300 dead and many taken prisoners - including 50 Frenchmen serving with the Swedes, and amongst other trophies Poles captured 3 cornet banners.

Therefore, shortly after their disengagement from the pursuit of the Swedish cavalry, the Polish commanders decided to avoid any further engagement with the Swedes and to withdraw their force and wagon trains from Chojnice towards Nakło nad Notecią, which they reached on January 7, 1658.

Polish army sustained light casualties: less than 50 killed and wounded, and 9 taken prisoner, number of horses and wagons were also taken in the initial surprise attack.

In pursuit, Czarniecki inflicted great losses on them, knocking out 1/3 of the Swedish soldiers, but faced with the approaching main force of Charles Gustav, the Poles retreated towards Nakło.
