The Battle of Chudnov took place between the forces of the Polish–Lithuanian Commonwealth, allied with the Crimean Tatars, and the Tsardom of Russia, allied with the Cossacks. It ended with a decisive Polish victory, and the truce of Chudnov (Polish: Cudnów). The entire Russian army, including its commander, was taken into jasyr slavery by the Tatars. The battle was a major victory for the Poles, who succeeded in eliminating most of Russian forces, weakened the Cossacks and kept their alliance with the Crimean Tatars. The Poles, however, were unable to capitalize on that victory; their army retreated in poor order. Furthermore, the country had failed to provide wages for most of the army, which resulted in mutinies in 1661. This prevented the Poles from taking initiative and allowed the Russians time to rebuild their armies.
