The Battle of Khotyn or Battle of Chocim or Hotin War (in Turkish: Hotin Muharebesi) was a battle, which took place between 2 September and 9 October 1621 between a Polish-Lithuanian Commonwealth army and an invading Ottoman Imperial army. For a whole month (2 September – 9 October), the Commonwealth forces halted the Ottoman advance. The Commonwealth commanding officer, Grand Hetman of Lithuania Jan Karol Chodkiewicz, held the forces of Sultan Osman II at bay until the first autumn snows, and in the end died during the battle. On 9 October, due to the lateness of the season and having sustained heavy losses in several assaults on fortified Commonwealth lines, the Ottomans abandoned their siege and the battle ended in stalemate, reflected in a treaty that in some sections favored the Ottomans and in others favored the Commonwealth.
