the hetman's authority and focus noblemen's attention on external instead of internal problems. Additionally, hetman Żółkiewski, foreseeing confrontation with the Ottoman Empire, preferred to meet their troops on foreign soil. In retrospect, this time the nobles were right about the lack of danger since neither Tatars nor Turks were ready in 1620. While the Sultan was indeed planning an expedition to Poland in 1621, this was to be done with a small contingent. However, it can be argued that the continuous policy of neglect for the military would dearly cost the Commonwealth in the coming decades. Battle of Cecora and its aftermath (1620–21) The next phase of the Ottoman-Commonwealth conflict would begin in 1620: the Cossacks' burning of Varna proved the last spark. The new young Ottoman sultan Osman II made peace with Persia and promised to burn the Commonwealth to the ground and "water his horses in the Baltic Sea". Żółkiewski's forces went deep into Moldavia to strike at Ottomans before they were ready, but a large Ottoman force had already invaded Moldavia to remove hospodar Graziani. In early September 1620 the Royal Grand and Field Hetman's Zolkiewski and his protegee, future hetman Stanisław Koniecpolski, assembled 8,000 men and marched south. However, Graziani's contribution comprised just 600 men. At the Battle of Cecora (September 18 to October 6, 1620), on the river Prut, Zolkiewski met the 22,000-strong army of Iskender Pasha, withstanding repeated attacks during September 1620. On September 29 he ordered a retreat, and for eight difficult days discipline held despite enemy attacks. On approaching the Polish border, order in much of the army melted and the forces disintegrated on the spot. The Ottomans attacked and much of the Commonwealth army was destroyed. Zolkiewski was killed, his head sent to the Sultan as a trophy, while Koniecpolski was captured. The following year, in 1621, an army of 100,000–160,000 Turkish soldiers led by Sultan Osman II in person advanced from Adrianople towards the Polish frontier, but the disaster of Cecora caused the Commonwealth to mobilise a large army (of about 25,000 Poles and 20,000 Cossacks) in response. Hetman Chodkiewicz crossed the Dniester in September 1621 and entrenched himself in the fortress of Khotyn on the very path of Ottoman advance. It was here that, for a whole month (September 2 to October 9), during the Battle of Khotyn, the Commonwealth hetman held the sultan at bay, up until the
