At that time the reorganized Lithuanians returned to the battle, attacking von Jungingen from the rear.[67] The Teutonic forces were by then becoming outnumbered by the mass of Polish knights and advancing Lithuanian cavalry. As von Jungingen attempted to break through the Lithuanian lines, he was killed.[67] According to Cronica conflictus, Dobiesław of Oleśnica thrust a lance through the Grand Master's neck,[67] while Długosz presented Mszczuj of Skrzynno as the killer. Surrounded and leaderless, the Teutonic Knights began to retreat.
