The Battle of Jarosław took place during the Deluge (part of the Second Northern War) on March 15, 1656. Polish-Lithuanian Commonwealth forces under the command of Stefan Czarniecki defeated the Swedish forces commanded by Charles X Gustav of Sweden. After the Battle of Golab, the Swedish army under King Charles X Gustav marched towards Lwow, where Polish forces concentrated, and where King John Casimir stayed. In early March 1656, Charles X Gustav received news that up to 20,000 Polish-Lithuanian soldiers concentrated in Red Ruthenia. The Swedish King realized that his forces were not adequate to face the enemy, so he ordered a retreat towards the San river. Furthermore, the Swedes were constantly attacked by Polish guerrilla forces. On March 11, first Swedish units reached the town of Jaroslaw, where they defeated a regiment of Hetman Jerzy Sebastian Lubomirski, which guarded the river crossings.
