Dyrrhachium, modern Durrës in Albania, is at the beginning of the Via Egnatia, the Roman road that connected the Adriatic Sea with Macedonia and the Aegean Sea. The town became the center of a series of military engagements during the Second Civil War (49-48), in which Julius Caesar (picture) fought against Pompey the Great and overthrew the Roman Republic.

In January 49, Caesar had invaded Italy at the Rubico, and Pompey had evacuated Italy, which could not be defended against Caesar's experienced soldiers (17 March). After a lightning campaign in Spain, Caesar directed his attention to Greece, where Pompey was building an army that consisted of nine legions. He wanted to invade Italy, and needed Dyrrhachium as his base. When the campaign started, he was still collecting his army to the southeast of this port.

Caesar employed eleven legions (V Alaudae, VI Ferrata, VII, VIII, VIIII, X Equestris, XI, XII, XIII, XIV, XXVII), but was unable to transport more than seven across the Adriatic Sea. Having landed at Apollonia, south of Dyrrhachium, Caesar immediately sent two legions to the east, to prevent Pompey from receiving reinforcements. With the remaining five units, Caesar marched to the north and placed his camp between Pompey and Dyrrhachium. When Pompey arrived, he built his camp at a hill called Petra, "rock". Because his men were untrained, he declined battle.
Therefore, Caesar started to build fortifications. This would prevent Pompey's soldiers from obtaining food from the countryside, prevented his cavalry from attacking, and -even more important- would give the impression that Pompey was besieged and did not dare to fight. So, Caesar's men contructed twenty-four forts and a wall of 22 kilometers.

Pompey started to build counter-works. There were several fights between the two Roman forces, in which Caesar's Ninth legion suffered badly, and the building of the circumvallations continued. In his History of the Civil War, Caesar tells that during one fight in a southern fort (see map), one centurion received no less than 120 blows on his shield - evidence of the discipline and high morale of the legionaries.

The southernmost part of Caesar's fortifications were still unfinished, and it was absolutely imperative for Pompey to break away from his camp before the circle would be closed. This became even more urgent after Caesar's lieutenant Marc Antony arrived with the remaining four legions. During a night, 7 July according to the Roman calendar (which is out of step with ours), Pompey ordered his soldiers to attack the unfinished part of Caesar's fortifications, and after a day of fighting, Caesar had to admit that he would not be able to regain control of this part of the battlefield. This meant that his circumvallation could not be closed, and he immediately broke off the siege, marching off to Thessaly in the east.

He had lost many men, had given Pompey a chance to train his recruits, and had no line of communication back to Italy. Still, his men remained disciplined and motivated, and within a month, they would prove their worth at Pharsalus.
