Italy on both seas was guarded by fleets, at Misenum and at Ravenna, and the contiguous coast of Gaul by ships of war captured in the victory of Actium, and sent by Augustus powerfully manned to the town of Forojulium. But our chief strength was on the Rhine, as a defence alike against Germans and Gauls, and numbered eight legions. Spain, lately subjugated, was held by three. Mauretania was king Juba's, who had received it as a gift from the Roman people. The rest of Africa was garrisoned by two legions, and Egypt by the same number. Next, beginning with Syria, all within the entire tract of country stretching as far as the Euphrates, was kept in restraint by four legions, and on this frontier were Iberian, Albanian, and other kings, to whom our greatness was a protection against any foreign power. Thrace was held by Rhœmetalces and the children of Cotys; the bank of the Danube by two legions in Pannonia, two in Mœsia, and two also were stationed in Dalmatia, which, from the situation of the country, were in the rear of the other four, and, should Italy suddenly require aid, not too distant to be summoned. But the capital was garrisoned by its own special soldiery, three city, nine prætorian cohorts, levied for the most part in Etruria and Umbria, or ancient Latium and the old Roman colonies. There were besides, in commanding positions in the provinces, allied fleets, cavalry and light infantry, of but little inferior strength. But any detailed account of them would be misleading, since they moved from place to place as circumstances required, and had their numbers increased and sometimes diminished.
