On the battlefield, in the midst of fighting, Brutus enters with Young Cato, Lucilius, and others. He urges them all to stand upright and brave. He exits, and Young Cato shouts his name and his loyalty to Rome, although some texts credit these lines, showing this loyalty to Brutus and Rome, to Lucilius. Young Cato is killed, and Lucilius is captured by Antony's soldiers who think that he is Brutus. He is then left under guard as one of the soldiers runs to bring Antony to the prisoner whom he believes to be Brutus. When Antony arrives and asks for Brutus, Lucilius tells him that Brutus is alive and will never be taken prisoner. Antony sets guard over the loyal Lucilius, and he sends his soldiers to search for Brutus and report to him later at Octavius' tent.
