While Caesar conquered in the West, Pompey the Great contended with Epirus, a wet, rugged and mountainous land which was a small enclave of territory between western Macedonia to the north and western Greece to the south. Not, as Pompey soon discovered, an easy place to assemble and train an army. He had headquartered himself on fairly flat land near the prosperous port city of Dyrrachium, convinced now that he would not see Caesar for some time to come. Caesar would attempt to neutralize the Spanish army first. It would be a titanic struggle between one veteran force and another—but fought on Pompeian ground in Pompeian country. Nor would Caesar have all nine legions at his disposal; he would have to garrison Italia, Illyricum, Gallia Comata—and find enough troops to equip someone to wrest the grain provinces from the true government. Even with whatever soldiers he had managed to persuade to change sides after Corfinium, he’d be lucky to be able to match the five legions of Afranius and Petreius.
