Germanicus commanded the Roman forces in their campaign of 14/16 AD against the Germanic tribes. Three whole Roman legions had been wiped out in the Battle of the Teutoburg Forest in 9 AD. It was the greatest disaster in Roman military history.
Plans for the revenge were started by the Emperor Augustus, and put into effect by his successor Tiberius. Germanicus had command of eight legions, one-third of the Roman Army. He destroyed the opposing German tribes, and recovered two of the three symbolic legionary eagles which had been lost. He was called back by Tiberius after he crossed the Rhine. The reasons for the recall are not agreed, but Augustus had set the Rhine as the limit of Rome's ambitions in Germany.
Germanicus was given an official triumph. A contemporary calendar gives 26 May as the day in which "Germanicus Caesar was borne into the city in triumph". Coins issued under his son Gaius (Caligula) depicted him on a triumphal chariot, with the reverse reading "Standards Recovered. Germans Defeated".
In AD 18 he was given charge of the eastern part of the empire. Germanicus died in Syria for unknown reasons.
