 After several costly (and failed) assaults in the first week of the siege, the Ottomans tried to take the Polish forces by cutting off their supplies and reinforcements and waiting for them to succumb to hunger and disease.A temporary bridge was raised by 14 September over the Dniester River that allowed the Ottomans to stop the Commonwealth fortress from using the river to communicate with another fortress at nearby Kamianets-Podilskyi, Ukraine.It also allowed the Ottomans to shift some of their cannons to the other bank of the river and shell Commonwealth forces from the rear.
