On 1 January 42 BC, the Senate posthumously recognized Julius Caesar as a divinity of the Roman state, "Divus Iulius". Octavian was able to further his cause by emphasizing the fact that he was "Divi filius", "Son of the Divine". Antony and Octavian then sent 28 legions by sea to face the armies of Brutus and Cassius, who had built their base of power in Greece. After two battles at Philippi in Macedonia in October 42, the Caesarian army was victorious and Brutus and Cassius committed suicide. Mark Antony later used the examples of these battles as a means to belittle Octavian, as both battles were decisively won with the use of Antony's forces. In addition to claiming responsibility for both victories, Antony also branded Octavian as a coward for handing over his direct military control to Marcus Vipsanius Agrippa instead.
