On 9 October, due to the lateness of the season and heavy losses - due to failed assaults on Commonwealth fortifications - the Ottomans abandoned their siege and the battle concluded with a stalemate, which is reflected in the treaty where some sections favour the Ottomans while others favoured the Commonwealth. Chodkiewicz died on 24 September 1621 shortly before concluding a treaty with the Turks.
