Plutarch wrote that Mark Antony was slow to respond to Labienus's invasions because he was caught up with the charms of Cleopatra in Egypt and a luxurious lifestyle, feasting, playing sports and engaging in other youthful pursuits. He was surprised by reports that his wife Fulvia had started a war with Octavian in Italy (the Perusine War, 41-40 BC) and that Labienus "was subduing Asia from the Euphrates and Syria as far as Lydia and Ionia." Cassius Dio, instead, wrote that Antony kept himself informed. However, he failed to take defensive measures, because now that he was in power he did not pay enough attention to his duties and enjoyed the life of luxury of the Egyptians “until he was entirely demoralised.” When he was forced to take action, he sailed to Tyre to help Tyre. However, when he saw that Syria had already been occupied, he abandoned it. He sailed along the coast all the way to Greece and then to Italy to support Fulvia in her war against Octavian. He seized Sipontum and besieged Brundisium. When Fulvia died, the hostilities were terminated and there was reconciliation. Antony and Octavian signed the Treaty of Brundisium in September 40 BC.
