After the aforementioned battle, Aulus Caecina Severus and Marcus Plautius Silvanus joined Tiberius and a huge army was assembled. Velleius Paterculus reported that they brought five legions (three from Moesia and two from the province of Asia, respectively). Tiberius had five legions (three in Pannonia and two in Dalmatia). The legions were not at full strength as Velleius Paterculus mentioned that there were seventy cohorts (ten legions at full complement would have had 100 cohorts). There were fourteen troops of cavalry, as well as 10,000 reservists, many volunteers, and the Thracian cavalry. There had not been such a large army gathered in a single location since the time of the Roman civil wars. Tiberius decided to escort the newly arrived armies back because the army was too large to be manageable. He then returned to Siscia at the beginning of a very hard winter.
