The Battle of Kletsk took place on 30 April 1706 (Gregorian calendar), in- and outside the city of Kletsk, Belarus during Charles XII's Polish campaign of 1701–1706, in the Great Northern War. The Swedish forces were led by Carl Gustaf Creutz who defeated a larger Russian–Cossack force under the command of Semjon Nepljujev and Danylo Apostol. Many of the Russian and Cossack regiments participating in the battle were wiped out and ceased to exist as fighting units. Some historians consider the main reason for the defeat to be the actions of the Ukrainian Cossacks, who immediately turned into a blameless flight at the sight of the Swedish attacks, disrupting the formation of the Russian units behind them.
