No one is waiting, on the contrary, civilian refugees from Banská Bystrica are also entrusted to his protection. In addition, the headquarters sends him to "take care" of captured German soldiers. A serious dispute arises over whether to liquidate the prisoners or not. The final decision must be made and enforced by Lieutenant Kubiš - he refuses to carry out the sentence without a decision from a field court. Kubiš sends the captured Germans - hostages to Banská Bystrica to guarantee the safe return of the civilian population to the city.
