[-12-] These were the operations at that point.--Seretium, which Tiberius had once besieged but not captured, was subdued, and after this some other towns were more easily won. But since the remainder even under these conditions offered resistance and the war kept lengthening out and famine came in its train, especially in Italy, Augustus sent Tiberius again into Dalmatia. He saw that the soldiers were not for enduring further delay and were anxious to end the war in some way eyen if it involved danger; therefore, fearing that if they remained in one place together they might revolt, he divided them into three parts. One he assigned to Silvanus and one to Marcus Lepidus; with the remainder he marched with Germanicus against Bato. Without difficulty the two former overcame those arrayed in battle opposite them. Tiberius himself went wandering off through practically the entire country, as Bato appeared first at one point and then at another: finally, Bato took refuge in Fort Andetrium, located close to Salonæ, and Tiberius, who besieged him, found himself in sore straits. The garrison had the protection of fortifications built upon a well guarded rock, difficult of access, encircled by deep ravines through which torrents roared, and the men had all necessary provisions, part of which they had previously stored there, while a part they were still bringing from the mountains, which were in their hands. Moreover, by ambuscades they interfered with the Roman provision trains. Hence Tiberius, though supposed to be besieging them, was himself placed in the position of a besieged force.
