Cassius Dio also wrote that there was famine in Italy largely due to the war. However, it has to be noted that most of the grain was imported from Egypt, the province of Africa, Sicily, and Sardinia. Therefore, it is unclear how the war in Illyricum caused famine in Italy. Augustus sent Tiberius back to Dalmatia. Tiberius split the army into three divisions to avoid a mutiny. He put Marcus Plautius Silvanus and Marcus Aemilius Lepidus in charge of two of them and led the third against Bato, taking Germanicus with him. The other two divisions easily defeated their enemies. Tiberius chased the fugitive Bato around the country, and finally besieged him at Adetrium, near Salona. This was on a rock and was surrounded by steep ravines. Tiberius held on until Bato was forced to seek terms. However, Bato could not persuade his comrades to accept a truce. Tiberius advanced against the fortress, keeping part of his force in reserve and sending the rest forward in a square formation. The rugged terrain stretched the advancing troops. On seeing this, the Dalmatians lined up outside the wall at the top of the slope and hurled stones at them, separating the Romans further. Tiberius prevented his men from retreating by continuously sending reinforcements. He sent a detachment to a point where the place could be ascended via a long route. Once it had been taken, the enemy could not enter the fortress and fled. They were later found hiding in the forest and were killed. Tiberius then negotiated the terms of capitulation.
