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. The Polish army was led by Duke Bolesław III Wrymouth, while the invading Imperial forces were commanded by King Henry V of Germany and included a Bohemian contingent under Duke Svatopluk of Bohemia. The Polish defense ended in a victory after the siege proved fruitless and was abandoned, and the episode later attained legendary status in Polish historiography.
