In November 1655, when Swedish forces reached Krosno, the town opened its gates to them.

The sejmik of the Przemysl Land, which convened here, pledged allegiance to Charles Gustav.

Soon afterwards, however, the residents of Krosno turned against the Swedes, who looted, plundered, murdered people and burned houses.

Organized by Colonel Gabriel Wojniłłowicz, they renounced their pledge and attacked the Swedish garrison, together with their Polish allies.

The people who had pledged allegiance to Charles, together with Pracki, were hanged in the market square, while Wojniłłowicz with his unit headed towards Biecz and Nowy Sącz.
