Römerlager Kneblinghausen

According to the portal https://www.alisonensis.de/  

Varus legions camp. Built on the 2nd day of the battle in the Teutoburg Forest. When the Roman camp at the end of the 2nd day was completed and the entire Roman marching column had arrived in Kneblinghausen, it became apparent that the camp was oversized with regard to the number of surviving legionaries: the number of legionaries was no longer sufficiently high to guard or defend trench and wall of the camp, and on the other hand to enable the legionnaires also a sleep break. For this reason, the east side the camp was shortened by 130 m, and the circumference of the camp accordingly reduced. 

This hypothesis is not supported by anything. The scholars are rather unanimous that the battle in the Teutoburg Forest took place in the north, near the town of Kalkriese. Varus led his legions west towards the Rhine. The place of the final battle between the Romans and Germans is located more than 100 kilometers north of the camp in Kneblinghausen.
