Julius Caesar and Pompey the Great were two of the greatest generals Rome had ever produced. Together they had brought vast stretches of territory under Roman dominion. In 49 BC they turned against each other and plunged Rome into civil war. Legion was pitched against legion in a vicious battle for political domination of the vast Roman world. Based on original sources, Adrian Goldsworthy provides a gripping account of this desperate power struggle. The armies were evenly matched but in the end Caesar’s genius as a commander and his great good luck brought him victory in 45 BC.
