Between 14 and 16 CE, Germanicus Julius Caesar, nephew and adopted son of Emperor Tiberius, led Roman armies across the Rhine into Germania in response to the destruction of three legions at the Teutoburg Forest in 9 CE. His forces recovered two of the three eagle standards lost under Varus, buried the remains of fallen soldiers at the Teutoburg battlefield, and defeated Arminius at the Battle of Idistaviso on the Weser River in 16 CE. Despite these successes, Tiberius recalled Germanicus, concluding that sustained occupation beyond the Rhine was not worth the cost.
