Battle of the Teutoburg Forest
The clades Lolliana or Lollian disaster was a battle in 16 BCE, when the consul Marcus Lollius Paulinus was defeated by the Sicambri, Tencteri and Usipetes, Germanic tribes who had crossed the Rhine. This defeat is coupled by the historian Suetonius with the disaster of Publius Quinctilius Varus in the Battle of the Teutoburg Forest, but it was disgraceful rather than dangerous.
