Prince and Princess Janusz had left with part of the court for the spring fishing at Czerska, of which sport he was extremely fond, and loved it above all others. The Bohemian got much important information from Mikolaj of Dlugolas, treating of private affairs as well as of the war. First he learned that Macko had apparently given up his intended route to Zmudz, the "Prussian enclosure," that a few days ago he had left for Warsaw where be found the princely pair. As to the war, old Mikolaj informed him all that he had already heard in Szczytno.
All Zmudz, as one man, had risen in arms against the Germans, and Prince Witold not only had refused to help the Order against the unhappy Zmudzians, but had not yet declared war against them, and was negotiating with them; but meanwhile he supplied the Zmudzians with money, men, horses and corn. Meanwhile, he, as well as the Knights of the Cross, sent ambassadors to the pope, to the emperor, and to other Christian lords, accusing each other of breach of faith, and treachery. The ambassador carrying the letters of the prince was the clever Mikolaj of Rzeniewa, a man of great ability who could unravel the thread which was woven by the artifice of the Knights of the Cross, convincingly demonstrating the great wrongs done to the lands of Lithuania and Zmudz.
Meantime when at the diet in Wilno the ties between the Poles and Lithuanians were strengthened, it acted like poison in the hearts of the Knights of the Cross. It was easy to foresee that Jagiello as the supreme lord of all the lands under the command of Prince Witold, would stand at his side in time of war. Count Jan Sayn, the comthur of Grudzia, and Count Schwartzburg of Danzig, went, at the request of the grand master, to see the king and asked him what might be expected from him. Although they brought him falcons and costly presents, he told them nothing. Then they threatened him with war, without really intending it, because they well knew that the grand master and the chapter were terribly afraid of Jagiello's forces, and were anxious to avert the day of wrath and calamity.
All their schemes were broken like cobwebs, especially with Prince Witold. The evening after Hlawa's arrival, fresh news reached Warsaw. Bronisz of Ciasnoc, courtier of Prince Janusz, whom the prince had previously sent for information from Lithuania, arrived, and with him were two important Lithuanian princes. They brought letters from Witold and the Zmudzians. It was terrible news. The Order was preparing for war. The fortresses were being strengthened, ammunition manufactured, soldiers, (knechts) and knights were gathering at the frontier, and the lighter bodies of cavalry and infantry had already crossed the frontier near Ragnety, Gotteswerder and other border strongholds.
