A note sent in August 1410 by envoys of King Sigismund of Hungary, Nicholas II Garai and Stibor of Stiboricz, put total casualties at 8,000 dead "on both sides".[71] However, the wording is vague and it is unclear whether it meant a total of 8,000 or 16,000 dead.[72] A papal bull from 1412 mentioned 18,000 dead Christians.[71] In two letters written immediately after the battle, Władysław II Jagiełło mentioned that Polish casualties were small (paucis valde and modico) and Jan Długosz listed only 12 Polish knights that were killed.[71] A letter by a Teutonic official from Tapiau (Gvardeysk) mentioned that only half of the Lithuanians returned, but it is unclear how many of those casualties are attributable to the battle and how many to the later siege of Marienburg.[71]
