The heavily forested, swampy terrain made the infantry manoeuvres of the legions impossible to execute and allowed the Germans to defeat the legions in detail. On the third day of fighting, the Germans overwhelmed the Romans at Kalkriese Hill, north of Osnabrück. Accounts of the defeat are scarce, due to the totality of the defeat, but Velleius Paterculus testifies that some Roman cavalrymen abandoned the infantry and fled towards the Rhine, but they were intercepted by the German tribesmen and killed. Varus himself, upon seeing all hope was lost, committed suicide. Arminius cut off his head and sent it to Bohemia as a present to King Marbod of the Marcomanni, the other most important Germanic leader, whom Arminius wanted to coax into an alliance, but Marbod declined the offer and sent the head on to Rome for burial.
