From The History of Rome by Theodor Mommsen. Book V. Chapter X
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.
