Battle of the Teutoburg Forest
The last chapter of this story is told by the historian Tacitus. Around 50 AD, bands of Chatti invaded Roman territory and began to plunder (take everything of value). The Roman commander, with a legionary force supported by Roman cavalry and auxiliaries, attacked the Chatti from both sides and defeated them. The Romans were very happy to find Roman prisoners, including some from Varus' legions who had been held by the Chatti for forty years.
