In November 1655, when Swedish forces reached Krosno, the town opened its gates to the invaders. The sejmik of the Przemysl Land, which convened here, pledged allegiance to Charles Gustav. Soon afterwards, however, residents of Krosno saw the real face of the Swedes, who looted, plundered, murdered people and burned houses. Organized by Colonel Gabriel Wojnillowicz, they renounced their pledge and attacked Swedish garrison, together with their Polish allies. Surprised Swedes lost the battle, and the Poles recaptured the town. Traitors, together with Pracki, were hanged in the market square, while Wojnillowicz with his unit headed towards Biecz and Nowy Sacz.
