Battle context
The Battle of Chojnice on 18 September 1454 was a significant engagement of the Thirteen Years' War between the Polish Crown and the Teutonic Order. Despite fielding a substantially larger force — approximately 16,000 troops against the Teutonic Order's 9,000 — the Polish Crown suffered casualties of around 3,000, suggesting a costly outcome for King Casimir IV's forces. Commanders on the Polish side included Jan Taszka Koniecpolski and Piotr of Szczekociny, while the Teutonic Order was led by Bernhard von Zinnenberg and Rudolf of Żagań. The disparity between force sizes and Polish losses points to a battle that went badly for the Crown early in what would prove a protracted conflict lasting until 1466.
