At the ball, Manrico appears dressed in his masked identity, pretending it is merely a costume for the festivities. When he and Rossana meet, she warns him about Titta's plan. Ostenburg recognizes Rossana and arrests her despite Manrico and Gualtiero's intervention. Just as she is about to be led away, Manrico's best friend Jandolo, disguised as the Lion of Saint Mark, bursts in and spirits her away, according to Manrico's plan. Titta and his men follow her and Manrico to her temporary refuge on Torcello, only to run into an ambush. After the pirates have fled, Manrico confesses to Rossana that he is the Lion of Saint Mark, and disgusted, Rossana declines his offer to marry him and rejoins Titta.
