In 1410, at the Battle of Grunwald ()—known in Lithuanian as the Battle of Žalgiris—a combined Polish-Lithuanian army, led by Vytautas and Jogaila, decisively defeated the Order in the Polish-Lithuanian-Teutonic War. Grand Master Ulrich von Jungingen and most of the Order's higher dignitaries fell on the battlefield (50 out of 60). The Polish-Lithuanian army then began the Siege of Marienburg, the capital of the Order, but was unable to take Marienburg owing to the resistance of Heinrich von Plauen. When the First Peace of Thorn was signed in 1411, the Order managed to retain essentially all of its territories, although the Knights' reputation as invincible warriors was irreparably damaged.
