tribunal immunity, or sacrosanctitas, in order to ensure his own safety and that of Livia and Octavia once he returned to Rome. War with Antony and Cleopatra Meanwhile, Antony's campaign turned disastrous against Parthia, tarnishing his image as a leader, and the mere 2,000 legionaries sent by Octavian to Antony were hardly enough to replenish his forces. On the other hand, Cleopatra could restore his army to full strength; he already was engaged in a romantic affair with her, so he decided to send Octavia back to Rome. Octavian used this to spread propaganda implying that Antony was becoming less than Roman because he rejected a legitimate Roman spouse for an "Oriental paramour". In 36 BC, Octavian used a political ploy to make himself look less autocratic and Antony more the villain by proclaiming that the civil wars were coming to an end and that he would step down as triumvir—if only Antony would do the same. Antony refused. Roman troops captured the Kingdom of Armenia in 34 BC, and Antony made his son Alexander Helios the ruler of Armenia. He also awarded the title "Queen of Kings" to Cleopatra, acts that Octavian used to convince the Roman Senate that Antony had ambitions to diminish the preeminence of Rome. Octavian became consul once again on 1 January 33 BC, and he opened the following session in the Senate with a vehement attack on Antony's grants of titles and territories to his relatives and to his queen. The breach between Antony and Octavian prompted a large portion of the senators, as well as both of that year's consuls, to leave Rome and defect to Antony. However, Octavian received two key deserters from Antony in the autumn of 32 BC: Munatius Plancus and Marcus Titius. These defectors gave Octavian the information that he needed to confirm with the Senate all the accusations that he made against Antony. Octavian forcibly entered the temple of the Vestal Virgins and seized Antony's secret will, which he promptly publicized. The will would have given away Roman-conquered territories as kingdoms for his sons to rule and designated Alexandria as the site for a tomb for him and his queen. In late 32 BC, the Senate officially revoked Antony's powers as consul and declared war on Cleopatra's regime in Egypt. In early 31 BC, Antony and Cleopatra were temporarily stationed in Greece when Octavian gained a preliminary victory:
