The Battle of Bertenau was a military engagement of the Great War between Apelia and Vierzland on a 200 kilometer-front on the outskirts of Bertenau, then the third-largest Vierz city. It occurred between MONTH and MONTH 1943. No fighting occurred in Bertenau itself, but large confrontations happened in nearby settlements such as Lettern and Oppitz.

Bertenau was a primary political and military focus of Apelia and the SIC. The Apelian strategic offensive, Operation TBD, saw the capture of the Vierz cities of Salzdorf and Tillena and the near-encirclement of the Borish capital Anderveld. Apelian forces rapidly moved towards Bertenau through seemingly-undefended territory.

Vierz defensive operations frustrated Apelian efforts, as Army Group West was able to secure additional divisions from the Eastern Front and slow the Apelian advance. Apelian forces were split between simultaneous offensives in Borland and Vierzland and became unable to break past Vierz defensive belts. The Apelian offensive totally froze on X X 1943 and resulted in the end of Operation TBD as an operational failure. The battle was a significant blow to the SIC offensive against Vierzland as a whole and resulted in Apelia shifting its overall strategic focus towards the ongoing Battle of Borland.
