forces in the Suceava Fortress (now Romania), Tymish, led by a 9,000-strong Cossack detachment, broke into the city on August 10. In the first decade of August, Hetman Bohdan sent a new Cossack corps to the Principality of Moldavia, led by his eldest son and son-in-law Vasily Lupu, Timosh Khmelnytsky. On August 17 or 18, the Cossacks entered in Suceava. Tymish marched in several columns, ravaging the country in order to provoke Stefan to withdraw from Suceava, as well as not giving the opportunity to accurately locate the direction of the march of its main forces. As a result, Stefan lifted the siege and Tymish was able to enter Suceava, barely meeting resistance (the blocking detachment of 500 soldiers left by Stefan was easily defeated). On August 21, Georgy Stefan's army approached Suceava and tried to take the Cossack camp under the walls of the fortress. This attempt completely failed, because in the few days that passed from the arrival to Suceava, the Cossacks were able to build strong fortifications; the siege of the fortress began. After the siege began, Tymish sent a letter to Bohdan Khmelnytsky asking for help. On August 29, Khmelnytsky received an alarming letter from his son requesting reinforcements. However, having only 10,000 soldiers in Chyhyryn (other regiments gathered near Bila Tserkva), he did not dare to send large forces to Suceava before the threat of an attack by the Poles (several thousand Cossacks could not save the situation). Therefore, he wrote back to Timosh that he could not send reinforcements at the moment and advised him to defend himself. Sources say that after that the hetman sent universals to the officers three times with an order to gather to help the besieged in Suceava, but they did not want to do it. In the second decade of September, only two regiments of Cossacks gathered in Rashkov. The heaviest fighting took place on September 10-12, when the Cossacks tried to break through the siege. This efficiency was most likely due to the fact that the blockade began to show in the fortress - food and gunpowder were running out, and water was running out. In addition, the Cossacks could decide that Dengoff's detachment, which had arrived in the first decade of September, was only the vanguard of a larger army. Tymish formed a strike group of up to 5,000 soldiers and directed the main blow at
