The Roman army was one of the most powerful military forces of the ancient world. It was said to be the equivalent of a barbarian army ten times its size, and when lead by an able general, this often proved to be the case. The Roman state did indeed provide some of histories greatest generals. From Marius, Pompey and Caesar in the Republic, to Agrippa, Vespasian, Trajan, and Severus in the principiate then right up to Aetius in the final days of the empire, the list goes on and on. Joe Medhurst compiles here some of the most dramatic and important victories of the period of the empire, starting with the Battle of Actium in the days of Rome's first emperor, Augustus, and finishing with the Battle of Chalons in the last century of the western empire.
