At an earlier time the Romans twice attacked the country of the Segestani, but obtained no hostages nor anything else, for which reason the Segestani became very arrogant. Augustus advanced against them through the Pannonian territory, which was not yet under subjection to the Romans. Pannonia is a wooded country extending from the Iapydes to the Dardani. The inhabitants do not live in cities, but scattered through the country or in villages according to relationship. They have no common council and no rulers over the whole nation. They number 100,000 fighting men, but they do not assemble in one body, because they have no common government. When Augustus advanced against them they took to the woods, from which they darted out and slew the stragglers of the army. As long as Augustus hoped that they would surrender voluntarily he spared their fields and villages. As none of them came in he devastated the country with fire and sword for eight days, until he came to the Segestani. Theirs is also Pannonian territory, on the river Save, on which is situated a city strongly fortified by the river and by a very large ditch encircling it. For this reason Augustus greatly desired to possess it as a magazine convenient for a war against the Dacians and the Bastarnae on the other side of the Ister, which is there called the Danube, but a little lower down is called the Ister. The Save flows into it, and Augustus caused ships to be built in the latter stream to bring provisions to the Danube for him.
 For these reasons he desired to obtain possession of Segesta. As he was approaching, the Segestani sent to inquire what he wanted. He replied that he desired to station a garrison there and to have them give him a hundred hostages in order that he might use the town safely as a base of operations in his war against the Dacians. He also asked for as much food as they were able to supply. The chief men of the town acquiesced, but the common people were furious, yet consented to the giving of the hostages, perhaps because they were not their children, but those of the notables. When the garrison came up, however, they could not bear the sight of them, but shut the gates in a mad fury and stationed themselves on the walls. Thereupon Augustus bridged the river and surrounded the place with ditch and palisade, and, having blockaded them, raised two mounds. Upon these the Segestani made frequent assaults and, being unable to capture them, endeavored to destroy them with torches and fire thrown from above. When aid was sent to them by the other Pannonians Augustus met and ambuscaded this reinforcement, destroyed a part of their force, and put the rest to flight. After this they got no more help from the Pannonians.
 Thus the Segestani, after enduring all the evils of a siege, were taken by force on the thirtieth day, and then for the first time they began to beg. Augustus, admiring them for their bravery and yielding to their prayers, neither killed nor banished them, but contented himself with a fine. He caused a part of the city to be separated from the rest by a wall, and in this he placed a garrison of twenty-five cohorts. Having accomplished this he went back to Rome, intending to return to Illyria in the spring. But a rumor becoming current that the Segestani had massacred the garrison, he set forth hastily in the winter. However, he found that the rumor was false, yet not without cause. They had been in danger from a sudden uprising of the Segestani and had lost many men by reason of its unexpectedness, but on the next day they rallied and put down the insurgents. Augustus turned his forces to Dalmatia, another Illyrian country bordering on Taulantia.
