Battle of the Frontiers
The Bavarian Army fought at the Battle of the Frontiers, the last time that it fought together as a single unit: the exclusive Bavarian command of Bavarian forces began to be diluted from the German Army reorganisations in Autumn 1914 onwards. Rupprecht held command for the duration of the war and was promoted to Field Marshal in 1916 largely on account of his outstanding ability; however, after Frontiers, the units under his command came largely from outside Bavaria.
