war. And so it happened; for Pompey, at first not knowing his design,
because he imagined he had taken a route in a different direction from
that country, thought that the scarcity of provisions had obliged him to
shift his quarters; but having afterwards got true intelligence from his
scouts, he decamped the day following, hoping to prevent him by taking a
shorter road; which Caesar suspecting might happen, encouraged his
troops to submit cheerfully to the fatigue, and having halted a very
small part of the night, he arrived early in the morning at Dyrrachium,
when the van of Pompey's army was visible at a distance, and there he
encamped.

XLII.--Pompey, being cut off from Dyrrachium, as he was unable to effect
his purpose, took a new resolution, and entrenched himself strongly on a
rising ground, which is called Petra, where ships of a small size can
come in, and be sheltered from some winds. Here he ordered a part of his
men-of-war to attend him, and corn and provisions to be brought from
Asia, and from all the countries of which he kept possession. Caesar,
imagining that the war would be protracted to too great a length, and
despairing of his convoys from Italy, because all the coasts were
guarded with great diligence by Pompey's adherents; and because his own
fleets, which he had built during the winter, in Sicily, Gaul, and
Italy, were detained; sent Lucius Canuleius into Epirus to procure corn;
and because these countries were too remote, he fixed granaries in
certain places, and regulated the carriage of the corn for the
neighbouring states. He likewise gave directions that search should be
made for whatever corn was in Lissus, the country of the Parthini, and
all the places of strength. The quantity was very small, both from the
nature of the land (for the country is rough and mountainous, and the
people commonly import what grain they use); and because Pompey had
foreseen what would happen, and some days before had plundered the
Parthini, and having ravaged and dug up their houses, carried off all
the corn, which he collected by means of his horse.

XLIII.--Caesar, on being informed of these transactions, pursued
measures suggested by the nature of the country. For round Pompey's
camps there were several high and rough hills. These he first of all
occupied with guards, and raised strong forts on them. Then drawing a
fortification from one fort to another, as the nature of each position
allowed, he began to
