The Deluge: Khmelnytsky Uprising: The Battle of Berestechko ends with a Polish victory.

The Deluge was a series of mid-17th-century military campaigns in the Polish–Lithuanian Commonwealth. In a stricter sense, the term refers to the Swedish invasion and occupation of the Commonwealth as a theatre of the Second Northern War (1655–1660) only; in Poland and Lithuania this period is called the Swedish Deluge, or less commonly the Russo–Swedish Deluge due to the simultaneous Russo-Polish War. In a wider sense, it applies to the period between the Khmelnytsky Uprising of 1648 and the Truce of Andrusovo in 1667, comprising the Polish theatres of the Russo-Polish and Second Northern Wars. The term "deluge" was popularized by Henryk Sienkiewicz in his novel The Deluge (1886).
