paragraph_text: Cleopatra in the Liberators' civil war
  
  Octavian, Antony, and Marcus Aemilius Lepidus formed the Second Triumvirate in 43 BC, in which they were each elected for five-year terms to restore order in the Republic and bring Caesar's assassins to justice. Cleopatra received messages from both Gaius Cassius Longinus, one of Caesar's assassins, and Publius Cornelius Dolabella, proconsul of Syria and Caesarian loyalist, requesting military aid. She decided to write Cassius an excuse that her kingdom faced too many internal problems, while sending the four legions left by Caesar in Egypt to Dolabella. These troops were captured by Cassius in Palestine.
  
  While Serapion, Cleopatra's governor of Cyprus, defected to Cassius and provided him with ships, Cleopatra took her own fleet to Greece to personally assist Octavian and Antony. Her ships were heavily damaged in a Mediterranean storm and she arrived too late to aid in the fighting. By the autumn of 42 BC, Antony had defeated the forces of Caesar's assassins at the Battle of Philippi in Greece, leading to the suicide of Cassius and Brutus.
  
  By the end of 42 BC, Octavian had gained control over much of the western half of the Roman Republic and Antony the eastern half, with Lepidus largely marginalized. In the summer of 41 BC, Antony established his headquarters at Tarsos in Anatolia and summoned Cleopatra there in several letters, which she rebuffed until Antony's envoy Quintus Dellius convinced her to come. The meeting would allow Cleopatra to clear up the misconception that she had supported Cassius during the civil war and address territorial exchanges in the Levant, but Antony also undoubtedly desired to form a personal, romantic relationship with the queen. Cleopatra sailed up the Kydnos River to Tarsos in Thalamegos, hosting Antony and his officers for two nights of lavish banquets on board the ship. Cleopatra managed to clear her name as a supposed supporter of Cassius, arguing she had really attempted to help Dolabella in Syria, and convinced Antony to have her exiled sister, Arsinoe IV, executed at Ephesus. Cleopatra's former rebellious governor of Cyprus was also handed over to her for execution.
