Pompeius like Caesar had disdained to make requisitions of infantry from them; only the Epirot, Aetolian, and Thracian militia were called out to guard the coast, and moreover 3000 archers from Greece and Asia Minor and 1200 slingers were taken up as light troops.
His Cavalry
The cavalry on the other hand--with the exception of a noble guard, more respectable than militarily important, formed from the young aristocracy of Rome, and of the Apulian slave-herdsmen whom Pompeius had mounted (25)--consisted exclusively of the contingents of the subjects and clients of Rome. The flower of it consisted of the Celts, partly from the garrison of Alexandria,(26) partly the contingents of king Deiotarus who in spite of his great age had appeared in person at the head of his troops, and of the other Galatian dynasts. With them were associated the excellent Thracian horsemen, who were partly brought up by their princes Sadala and Rhascuporis, partly enlisted by Pompeius in the Macedonian province; the Cappadocian cavalry; the mounted archers sent by Antiochus king of Commagene; the contingents of the Armenians from the west side of the Euphrates under Taxiles, and from the other side under Megabates, and the Numidian bands sent by king Juba--the whole body amounted to 7000 horsemen.
Fleet
Lastly the fleet of Pompeius was very considerable. It was formed partly of the Roman transports brought from Brundisium or subsequently built, partly of the war vessels of the king of Egypt, of the Colchian princes, of the Cilician dynast Tarcondimotus, of the cities of Tyre, Rhodes, Athens, Corcyra, and generally of all the Asiatic and Greek maritime states; and it numbered nearly 500 sail, of which the Roman vessels formed a fifth. Immense magazines of corn and military stores were accumulated in Dyrrhachium. The war-chest was well filled, for the Pompeians found themselves in possession of the principal sources of the public revenue and turned to their own account the moneyed resources of the client- princes, of the senators of distinction, of the farmers of the taxes, and generally of the whole Roman and non-Roman population within their reach. Every appliance that the reputation of the legitimate government and the much-renowned protectorship of Pompeius over kings and peoples could move in Africa, Egypt, Macedonia, Greece, Western Asia and Syria, had been put in motion for the protection of the Roman republic; the report which circulated in Italy that Pompeius was arming the Getae, Colchians, and Armenians against Rome, and the designation of "king of kings" given to Pompeius in the camp, could hardly be called exaggerations. On the whole he had command over an army of 7000 cavalry and eleven legions, of which it is true, but five at the most could be described as accustomed to war, and over a fleet of 500 sail. The temper of the soldiers, for whose provisioning and pay Pompeius manifested adequate care, and to whom in the event of victory the most abundant rewards were promised, was throughout good, in several-- and these precisely the most efficient--divisions even excellent but a great part of the army consisted of newly-raised troops, the formation and training of which, however zealously it was prosecuted, necessarily required time. The force altogether was imposing, but at the same time of a somewhat motley character.
Junction Of The Pompeians On The Coast Of Epirus
According to the design of the commander-in-chief the army and fleet were to be in substance completely united by the winter of 705-706 along the coast and in the waters of Epirus. The admiral Bibulus had already arrived with no ships at his new headquarters, Corcyra. On the other hand the land-army, the headquarters of which had been during the summer at Berrhoea on the Haliacmon, had not yet come up; the mass of it was moving slowly along the great highway from Thessalonica towards the west coast to the future headquarters Dyrrhachium; the two legions, which Metellus Scipio was bringing up from Syria, remained at Pergamus in Asia for winter quarters and were expected in Europe only towards spring. They were taking time in fact for their movements. For the moment the ports of Epirus were guarded, over and above the fleet, merely by their own civic defences and the levies of the adjoining districts.
Caesar Against Pompeius
It thus remained possible for Caesar, notwithstanding the intervention of the Spanish war, to assume the offensive also in Macedonia; and he at least was not slow to act. He had long ago ordered the collection of vessels of war and transports in Brundisium, and after the capitulation of the Spanish army and the fall of Massilia had directed the greater portion of the select troops employed there to proceed to that destination. The unparalleled exertions no doubt, which were thus required by Caesar from his soldiers, thinned the ranks more than their conflicts had done and the mutiny of one of the four oldest legions, the ninth on its march through Placentia was a dangerous indication of the temper prevailing in the army; but Caesar's presence of mind and personal authority gained the mastery, and from this quarter nothing impeded the embarkation. But the want of ships, through which the pursuit of Pompeius had failed in March 705, threatened also to frustrate this expedition. The war-vessels, which Caesar had given orders to build in the Gallic, Sicilian, and Italian ports, were not yet ready or at any rate not on the spot; his squadron in the Adriatic had been in the previous year destroyed at Curicta;(27) he found at Brundisium not more than twelve ships of war and scarcely transports enough to convey over at once the third part of his army--of twelve legions and 10,000 cavalry--destined for Greece. The considerable fleet of the enemy exclusively commanded the Adriatic and especially all the harbours of the mainland and islands on its eastern coast. Under such circumstances the question presents itself, why Caesar did not instead of the maritime route choose the land route through Illyria, which relieved him from all the perils threatened by the fleet and besides was shorter for his troops, who mostly came from Gaul, than the route by Brundisium.
