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. However, 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, but 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.
