The Battle of Klissow took place on July 8 (Julian calendar) / July 9 (Swedish calendar) / July 19, 1702 (Gregorian calendar) near Kliszów, Poland-Lithuania, during the Great Northern War. The numerically superior Polish-Saxon army of August II the Strong, operating from an advantageous defensive position, was defeated by a Swedish army half its size under the command of king Charles XII.[5]
