After the battle, the Polish and Lithuanian forces delayed their attack on the Teutonic capital in Marienburg (Malbork), remaining on the battlefield for three days and then marching an average of only about 15 km (9.3 mi) per day.[79] The main forces did not reach heavily fortified Marienburg until 26 July. This delay gave Heinrich von Plauen enough time to organize a defense. Władysław II Jagiełło also sent his troops to other Teutonic fortresses, which often surrendered without resistance,[80] including the major cities of Danzig (Gdańsk), Thorn (Toruń), and Elbing (Elbląg).[81] Only eight castles remained in Teutonic hands.[82] The besiegers of Marienburg expected a speedy capitulation and were not prepared for a long siege, suffering from lack of ammunition, low morale and an epidemic of dysentery.[83] 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.[84]
