Drusus had little time to mourn the death of Augustus or celebrate the ascendance of his father Tiberius: the legions in the Rhine and Illyricum were in mutiny. They had not received the bonuses promised to them by Augustus, and when it became clear a response from Tiberius was not forthcoming, they revolted. On 17 or 18 September, Drusus was sent to deal with the troops in Illyricum, and a delegation was sent to confer proconsular "imperium maius" upon Germanicus, who dealt with the situation on the Rhine. Drusus did not require proconsular powers because he was consul designate.
