Vratislaus II of Bohemia
Henry invaded Saxony again in autumn 1075. Godfrey the Hunchback, Duke of Lower Lorraine, was the sole German duke to join his campaign, but the Saxons were unable to resist. Otto of Nordheim convinced them to surrender unconditionally to the King on 26 or 27 October. Henry pardoned Otto and returned all his benefices except Bavaria. He showed no mercy to other rebel leaders, who were imprisoned and had their estates confiscated. Henry summoned the German dukes to Goslar to swear fealty to his two-year-old son, Conrad, as his successor, but only Duke Vratislaus II of Bohemia obeyed his command.
