Heinrich von Plauen (the Elder) (c. 1370 – 1429) was the 27th Grand Master of the Teutonic Knights, serving from November 1410 to October 1413.

The siege, holding Jogaila's army in place, helped to organize defensive forces in other parts of Prussia and gave time for relief to arrive from the Livonian Order and Germany.

Von Plauen ordered his forces to pursue the retreating Polish army and recaptured all fortresses (except those on the Polish–Prussian border) by the end of October.

[6] To raise the money for the first installment, von Plauen called representatives of Prussian cities to Osterode (Ostróda) in February 1411.

When von Plauen saw that he could not make the third payment on time he asked Sigismund, Holy Roman Emperor for help.

In August 1412 the emperor delivered his decision that the Peace of Thorn was just and that a commission should negotiate a reduction to the war indemnity.

On 3 May 1413 Benedict Makrai, appointed by Sigismund, decided that the right bank of the Neman River, including Memel (Klaipėda), should belong to Lithuania.

[11] Despite the Order's financial troubles and weakened military capability after the defeat of 1410, von Plauen started preparations for another war with the Kingdom of Poland.

[14] Küchmeister disapproved of von Plauen's decision to wage another war and supported further peace talks with the Kingdom of Poland and the Grand Duchy of Lithuania.

Herman Gans was appointed as an interim Grand Master until a formal general assembly would meet in January 1414.

[16] Küchmeister unsuccessfully reopened diplomatic talks with Poland and a brief Hunger War broke out in summer 1414.
