Polish–Lithuanian–Teutonic War
Siege of Marienburg

After the battle, the Polish and Lithuanian forces delayed their attack on the Teutonic capital in Marienburg (Malbork) by staying on the battlefield for three days and then marching an average of only about 15 km (9.3 mi) per day. The main forces did not reach heavily fortified Marienburg until 26 July. This delay gave Heinrich von Plauen enough time to organize a defense. Polish historian Paweł Jasienica speculated that this was likely an intentional move by Jagiełło, who together with Vytautas preferred to keep the humbled but not decimated Order in play as to not upset the balance of power between Poland (which would most likely acquire most of the Order possessions if it was totally defeated) and Lithuania; but a lack of primary sources precludes a definitive explanation.

Jogaila, meanwhile, also sent his troops to other Teutonic fortresses, which often surrendered without resistance, including the major cities of Danzig (Gdańsk), Thorn (Toruń), and Elbing (Elbląg). Only eight castles remained in Teutonic hands. The Polish and Lithuanian besiegers of Marienburg were not prepared for a long-term engagement, suffering from lack of ammunition, low morale, and an epidemic of dysentery. The Knights appealed to their allies for help and Sigismund of Hungary, Wenceslaus, King of the Romans, and the Livonian Order promised financial aid and reinforcements. The siege of Marienburg was lifted on 19 September. The Polish–Lithuanian forces left garrisons in fortresses that were captured or surrendered and returned home. However, the Knights quickly recaptured most of the castles. By the end of October, only four Teutonic castles along the border remained in Polish hands. Jogaila raised a fresh army and dealt another defeat to the Knights in the Battle of Koronowo on 10 October 1410. Following other brief engagements, both sides agreed to negotiate.
