Cassius Dio reports that, after the games, Gaius was given command of the legions on the Ister (Danube), and that he did not take part in actions as he was there to learn (Dio, LV.10).
In 2 BC, Julia the Elder was forced into exile after she had received a letter in Tiberius' name. She was deemed guilty of committing adultery on multiple accounts by her father Augustus (Dio, LV.10; Suetonius, The Lives of the Twelve Caesars. "Augustus", 65).
