Russian and Ukrainian Cossack forces under Vasily Borisovich Sheremetev and Bohdan Khmelnytsky engaged a Polish–Lithuanian army under Stanisław "Rewera" Potocki near Gródek Jagielloński, which at that time was part of Polish–Lithuanian Commonwealth's Ruthenian Voivodeship (now Horodok, Lviv Oblast, Ukraine).
Russian-Cossack forces were faced by a numerically inferior Polish Crown army commanded by Hetman Stanislaw "Rewera" Potocki.
The Poles were supported by light Crimean Tatar cavalry, but their forces were inadequate to stop the Russians, and were steadily pushed westwards by the invaders.
After the victory, Russians and Cossacks besieged Lwow: to save itself, the city paid an enormous sum of money.
To save his army from complete annihilation, Potocki surrendered to King of Sweden Charles X Gustav, on October 28, 1655.
