In page Battle of the Teutoburg Forest:

"

Excavations have revealed battle debris along a corridor almost 24 kilometres (15 mi) from east to west and little more than 1.6 kilometres (1 mi) wide. A long zig-zagging wall of peat turves and packed sand had apparently been constructed beforehand: concentrations of battle debris in front of it and a dearth behind it testify to the Romans' inability to breach the Germanic tribes' strong defence. Human remains appear to corroborate Tacitus' account of the Roman legionaries' later burial.[8] Coins minted with the countermark VAR, distributed by Varus, also support the identification of the site. As a result, Kalkriese is now perceived to be an event of the Battle of the Teutoburg Forest.[citation needed]
