The Battle of Chojnice (Battle of Konitz) occurred on 18 September 1454 near the town of Chojnice, between Poland and the Teutonic Knights during the Thirteen Years' War. The battle was won by the Teutonic Knights.


The Teutonic army had around 9,000 cavalry and 6,000 infantry under Bernhard von Zinnenberg. The Polish army had 16,000 cavalry, a few thousand servants (who could and usually were used in battles), a few hundred infantry plus 500 mercenaries and burghers from Gdańsk and 2,000 mercenaries hired by the Prussian Confederacy, all under the command of King Casimir IV, advised by chancellor Jan Koniecpolski and Piotr from Szczekociny.

The Polish commanders were counting on the battle being won by the Polish heavy cavalry, not caring much about either artillery or infantry. They had not thought that their opponents could change their traditional strategy, or that the Teutonic soldiers besieged in Chojnice could be anything more than spectators. Bernard von Zinnenberg, nonetheless, had planned a totally different kind of battle.
