Opis: In Hungary, the national movement led by Kossuth has been crushed and the Austrian hegemony re-established, but partisans carry on with violent actions. In order to root out the guerilla, the army rounds up suspects and jails them in an isolated fort. The authorities do not have the identity of the guerilla leaders, who are supposed to be present among the prisoners. However, they know enough about some of the suspects to apply perfidious forms of coercion effectively.
