context_page_description: William I of Guelders and Jülich KG was Duke of Guelders, as William I, from 1377 and Duke of Jülich, as William III, from 1393. William was known for his military activities, participating in the Prussian crusade five times and battling with neighbors in France and Brabant throughout his rule. His allies included Holy Roman Emperors, Charles IV and Wenceslaus, Richard II of England, and Conrad Zöllner von Rothenstein, the Grand Master of the Teutonic Knights. During his reign the duchies of Guelders and Jülich were temporarily unified.
context_section_description: Shortly after his campaigns in Brabant, William departed again for Prussia with a large army.  He was quite successful in this crusade, but was taken prisoner near Stolpe in Pomerania, the land of Wartislaw VII, Duke of Pomerania.  He was taken to the castle of Falkenburg, where he stayed for six months.  Conrad Zöllner von Rothenstein, the grand master of the Teutonic Order, won his freedom.  William demanded that his freedom be formally declared, but the Pomeranian was embarrassed by his defeat.  In fear of the citizens, the Pomeranian nobleman hid in a tree on one side of a brook and shouted his declaration of William's freedom to William and the Teutonic Knights who were on the other side.  William then returned to Guelders by way of Bohemia, where he visited his brother-in-law, Wenceslaus, King of the Romans.
