of Tiberius [AD 37]". Augustus noted the successes of Drusus' campaigns—for which, as Drusus' superior, he took credit—in his Res Gestae Divi Augusti, written in 14 AD: Upon Claudius' accession to the principate in 41 AD, his late father Drusus received new public honors, including annual games in the Circus Maximus on 14 January for Drusus' birthday, coin issues depicting Drusus' likeness and his commemorative arch, and the restoration of a monument near the Ara Pacis Augustae that featured a statue of Drusus. Claudius also completed a road from Italy into Raetia that followed the route Drusus had taken and whose road-markers commemorated Drusus' achievements in the Alpine war. Such Claudian commemorations of Drusus' memory are thought to have become less prominent once Claudius had his own British triumph to celebrate. Historian Michael McNally considers Drusus to have been the most able of the various Roman commanders who attempted to conquer Germania, as well as the most successful. While the furthest extent of territorial gains would be realized the year after his death, under Tiberius, Drusus' death marked a slowing of Roman expansion. Drusus' successors would prove unfit for the task of conquering Germania, with disastrous results. Drusus was succeeded as commander in Germania by Tiberius, but Tiberius fell out of imperial favor, and chose self exile in 6 BC. Command then fell to Lucius Domitius Ahenobarbus. Ahenobarbus was partly successful, becoming the first and last Roman general to cross the Elbe river, but was generally bogged down in suppressing revolts. Command then fell to Publius Quinctilius Varus, under whom the Battle of the Teutoburg Forest (also called the Varian disaster) would occur. The destruction of Varus' entire army marked the end of northward Roman expansion. The Rhine became the de facto border of the Roman empire, rendering moot much of Drusus' life work.
