At the same time the great stretch of country from Istria to Macedonia and from the Adriatic to the Save was won for the empire; what had hitherto been the maritime province of Illyricum was not only augmented by the addition of the territory of the Iapydes (Iapodes) and Dalmatians, but a station and magazine was established on the lower Danube by the conquest of the Pannonian town of Siscia at the confluence of the Colapis (Kulpa) and Save. In vain did the Iapydes defend their capital with the courage of desperation; the emperor himself, though wounded in the thigh and in both arms, prosecuted the attack until all men capable of bearing arms had fallen in the fray, and the women, old men, and children had perished either in the flames of the burning town or by their own hands. In a very short time strong fortified lines were drawn through Pannonia and Mœsia to the southern bank of the river, and presently a continuous chain of fortresses under the charge of six legions prepared the way for the acquisition of fresh provinces, and warded off the raids of the northern barbarians.
The Thracian principalities south of the Hæmus sank into a more and more dependent position. In the reign of Tiberius, Cotys, a gentle and amiable prince, was murdered by his cruel uncle Rhescuporis. The widow appealed to Rome, whereupon the perpetrator of the crime was deposed by a decree of the senate, and the country divided between the sons of the two kings. Under these circumstances the sovereignty of Rome struck ever deeper root, till at length the last shadow of liberty and independence vanished and the whole of Thrace was gathered into the ample bosom of the world-empire.
The attempts at revolt made by the Pannonians and Dalmatians in the years 12 and 11 B.C. were savagely suppressed by Agrippa, and after his death by his successor Tiberius. The deportation of the men capable of bearing arms into slavery and the disarmament of the remainder re-established quiet and submission for a long while. But the love of liberty was not quelled in this warlike race. Infuriated by the extortions of Rome, who—in the words of one of their leaders—sent “not shepherds and dogs, but wolves, to tend the flocks,” and at the enlistment of their gallant sons for service in foreign parts, the Dalmatians and Pannonians again drew the sword in the year 6 A.D. to free themselves from the burdens of taxation and military service.
The rebellion spread rapidly through the whole country; enterprising leaders, two of whom bore the name of Bato, marched upon the Roman fortresses of Sirmium and Salona, ravaging the land as they went, while others harassed Macedonia with a large army. A bold troop of armed men threatened to invade Italy by way of Tergeste (Trieste); a disquieting agitation was abroad among the fierce Dalmatian and Sarmatian horsemen of the grassy steppes beyond the Danube; Roman traders were robbed and murdered. The alarm which took possession of the capital at these woeful tidings, and the military activity aroused throughout all Italy, sufficiently prove that Rome did not underestimate the danger that menaced her from the East. Discharged veterans were again enrolled in the legions, a slave tax was imposed to defray the cost of the war, peace was concluded with Marboduus, the prince of the Marcomanni, whom the Romans were on the point of attacking.
This devastating war, according to Suetonius the most terrible since the Punic Wars, lasted for three years [7-9 A.D.]. Tiberius and his nephew Germanicus, the son of Drusus, marched through the length and breadth of Dalmatia and Pannonia—now tempting the fortune of war, now treading the paths of treachery, and fostering discord by negotiations. After many sanguinary battles Bato came to terms with the Romans for the surrender of the impregnable mountain stronghold of Anderium, not far from Salona, and went with his family to Ravenna, where Tiberius granted him a liberal allowance to the end of his days, in recompense for his desertion of his country’s cause.
The fortress of Arduba, built on a steep height and protected by a turbulent river, held out longer; the most determined of the insurgents had thrown themselves into it, together with a large number of deserters. But its hour at length drew nigh. After the flower of the garrison, having made a sortie, had fallen in a sanguinary fight at close quarters, the survivors set fire to their homes and, with their wives and children, sought death in the flames or in the foaming torrent. The other towns then surrendered at discretion, and mute obedience settled once more on all the land between the Adriatic and the lower Danube. But the country was waste and inhabitants were few in the blood-sodden fields. The great river from source to mouth soon formed the northern boundary of the empire. The Thracian principalities were merged into the province of Mœsia.
