In the Battle of Actium in 31 BC, he commanded Antony's land forces against Octavian, having advised Antony before the battle that it would be more advantageous for their forces, together with those of Cleopatra, to fight on land, where they would have had the advantage over those of Octavian.Plutarch, Life of Antony Smith, W. (Ed.). (1870). Dictionary of Greek and Roman biography and mythology (Vol.1, p.872). On the outbreak of the war many of Antony's friends advised him to remove Cleopatra from the army, but Crassus who was bribed by the queen, opposed this plan, and she accordingly accompanied her lover to the fatal war. Shortly afterwards, however, Crassus also advised Antony to send her back to Egypt, and to fight the decisive battle on the land and not on the sea. This time his advice was disregarded. After Antony's defeat and flight to Egypt, Crassus was accused of deserting his army. He went to Egypt, where he was executed on Octavian's order.Hazel, John (2002), Who's Who in the Roman World, p. 85. Routledge, .
