he chained the child hostages to his siege engines, hoping that the people of Głogów would not shoot their own offspring, which would allow him to conquer the Polish settlement. However, Gallus stated that his cruelty towards children only strengthened the resolve of Głogów's defenders. Several harsh attacks by the Imperial army were repulsed, while Henry suffered significant losses by Polish guerilla fighters. After many days of unsuccessful fighting, the King was forced to abandon the siege and march south. Aftermath King Henry's campaign turned out to be a complete failure, when it ended in Bolesław's final victory at the Battle of Hundsfeld (Psie Pole). Duke Svatopluk was assassinated - probably by Bohemian Vršovci liensmen - still at the Głogów camp on September 21. His successor, Vladislaus, reconciled with Bolesław, whereafter Zbigniew was able to return to Poland in 1111, only to be arrested and blinded by his half-brother shortly afterwards. Bolesław's position towards the Empire was strengthened, and in the following years he was able to consolidate his rule in Pomerania and Lubusz Land. It was not until 1157, when Emperor Frederick Barbarossa in aid of the Silesian Duke Władysław II the Exile launched a successful campaign to the Polish lands. After centuries-long ambivalent relations with Germany, the successful defense and the tradition of Henry's cruelty had evolved to a key element in the memory of the Polish nation. A first memorial stone was erected by the Głogów citizens on the occasion of the 850th anniversary of the battle in 1959. On 1 September 1979 a large Socialist Realistic memorial to the Głogów children was inaugurated to commemorate not only the 870th anniversary but also the 40th memorial day of the German Invasion of Poland. The Battle of Głogów is commemorated on the Tomb of the Unknown Soldier, Warsaw, with the inscription "GLOGOW 1109".
