The river crossing remained secret until Hungarian envoys, who were attempting to negotiate a peace, informed the Grand Master.[47] As soon as Ulrich von Jungingen grasped the Polish–Lithuanian intentions, he left 3,000 men at Schwetz (Świecie) under Heinrich von Plauen[48] and marched the main force to organize a line of defense on the Drewenz River (Drwęca) near Kauernik (Kurzętnik).[49] The river crossing was fortified with stockades.[50] On 11 July, after meeting with his eight-member war council,[5] Władysław II Jagiełło decided against crossing the river at such a strong, defensible position. The army would instead bypass the river crossing by turning east, towards its sources, where no other major rivers separated his army from Marienburg.[49] The march continued east towards Soldau (Działdowo), although no attempt was made to capture the town.[51] The Teutonic army followed the Drewenz River north, crossed it near Löbau (Lubawa) and then moved east in parallel with the Polish–Lithuanian army. According to the Order propaganda the latter ravaged the village of Gilgenburg (Dąbrówno).[52] Later, in the self-serving testimonies of the survivors before the Pope the Order claimed that Von Jungingen was so enraged by the alleged atrocities that he swore to defeat the invaders in battle.[53]
