The Henry V's expedition to Poland was a conflict between Bolesław III Wrymouth and Henry V, the reason for the war was the exile from Poland of Bolesław's brother Zbigniew who sought support from the German Emperor to restore his power in the country. Henry V, Zbigniew and Bohemian Duke Svatopluk set out on an armed expedition into Poland, where they besieged the border town of Głogów, which they failed to conquer, but were also defeated in the Battle of Hundsfeld. The war ended with the defeat of German-Bohemian forces.
