Cassius Dio, instead, wrote that Tiberius returned to Rome. Germanicus was unable to take the well-fortified Splonum by storm. However, when a parapet of the wall fell, the inhabitants panicked, abandoning that part of the wall and fleeing to the citadel, where they eventually surrendered. At Raetinum the inhabitants set a slow-burning fire. When the Romans entered the town they did not notice it and then found themselves surrounded by the flames and pelted from the wall of the citadel, most of them dying in the trap. The people in the citadel had to escape to subterranean chambers in the night. Germanicus then seized Seretium and then the other places fell easily. However, other Dalmatians revolted.
