During the 1384 assault, the Lithuanians deployed cannons and trebuchets; the besieged Teutonic Knights had also installed cannons in the castle, which apparently destroyed the Lithuanians' trebuchet.
Za napada 1384., Litvanci su rasporedili topove i trebušete; Teutonski vitezovi, koji su bili pod opsadom, su također postavili topove u dvorce, koji su najvjerojatnije uništili litvanski trebušet.
