Beresteczko (1651), Połonka (1660), Cudnów (1660), Chocim (1673), Lwów (1675), Vienna (1683) and Párkány (1683), the Polish-Lithuanian hussars proved to be the decisive factor, often against overwhelming odds. For instance, in the Battle of Kłuszyn, during the Polish-Muscovite War, the Russians and Swedes outnumbered the commonwealth army five-to-one, yet were soundly defeated.
