The chapter begins outside the bandit camp of Pribyslavitz. Sir Radzig and Sir Robard have mustered enough men for an assault. Listen to the instruction of Sir Radzig and take the initiative in completing each objective as they arise.
As you charge the archers to the right of the bridge, a number of bandits will emerge from the foliage in answer to the attack.
Once you have dealt with the counter attack, wait a moment for Sir Radzig to reorganise the troops before charging into the camp.
When you have defeated the second wave of bandits and Cumans, a cut scene will follow in which a wagon that is blocking entrance to the camp is moved out of the way.
With the archers and the Cuman commander defeated, follow Sir Radzig and fight your way through to the church where the last of the bandits and Cumans are gathered.
