During the siege, legendary Polish hero, stolnik przemyski pułkownik Jerzy Wołodyjowski led many successful sallies with light cavalry.

Polish forces were commanded by Starosta of Podole, Mikolaj Potocki, and consisted of several units, such as infantry regiment of Bishop of Kraków Andrzej Trzebicki, two regiments of Captains Wasowicz and Bukar, permanent garrison of Major Kwasiborski, and other smaller units under Jan Mokrzycki, Jerzy Wolodyjowski, Rotmeister Myliszewski, Chorazy Wojciech Humecki, Stolnik Stanislaw Makowiecki, and Czesnik Jozef Wasilkowski.

First Crimean Tatar units appeared near Kamieniec Podolski on August 12, and two days later, main Ottoman army camped by the town.

It paralyzed Polish defence, and on August 20, the Turks managed to score a direct hit in one of the towers of the Old Castle, which served as an ammunition depot.

In 1692, to stop a possible Turkish attack, Hetman Stanislaw Jan Jablonowski built the stronghold of Okopy Swietej Trojcy some 20 kilometres (12 mi) from Kamieniec.
