The siege of Warsaw took place between April 24 and July 1, 1656. Swedish Empire forces had occupied the Polish capital without fighting in early September 1655 (see deluge). In late April 1656, Poles and Lithuanians began the siege, with the purpose of recapturing their capital. They were successful, but later lost the city for a second time after a battle held on July 28–30, 1656 (see Battle of Warsaw (1656)).
