Siege of Głogów

The Siege of Głogów or Defense of Głogów (German: Schlacht bei Glogau, Polish: Obrona Głogowa) took place on 24 August 1109 at the Silesian town of Głogów, between the Kingdom of Poland and the Holy Roman Empire. The event, recorded by the chronicler Gallus Anonymus in his Gesta principum Polonorum, is one of the most well-known episodes of early Polish medieval history.
