Julius Caesar and Pompey the Great were two of the greatest generals Rome ever produced. Together they had brought vast stretches of territory under Roman dominion. But in 49 BC they turned against one another and plunged Rome into civil war, with legion pitched against legion in a vicious battle for political domination of the vast Roman world. Based on original sources, Adrian Goldsworthy's book provides a gripping account of this desperate power struggle, in which the armies were evenly matched but Caesar's genius as a commander and his remarkable luck brought him victory in 45 BC.
