Meanwhile, several companies of Polish soldiers march into Dubno to relieve the siege, and destroy a regiment of Cossacks. A number of battles ensue. Taras learns of his son's betrayal from Yankel the Jew, whom he saved earlier in the story. During one of the final battles, he sees Andriy riding in Polish garb from the castle and has his men draw him to the woods, where he takes him off his horse. Taras bitterly scolds his son, telling him "I gave you life, I will take it", and shoots him dead.
