On October 3, 1914, the new Bavarian 3rd Reserve Brigade joined the division from the 30th Reserve Division. In addition, the 1st and 9th Mixed Replacement Brigades were redesignated as the 1st and 9th Replacement Brigades and their cavalry, artillery and engineer units were moved to division level. Three battalions from each brigade were reorganized into Kgl. Bayer. Ersatz-Infanterie-Regiment Nr.1 (1st Replacement Brigade) and Kgl. Bayer. Ersatz-Infanterie-Regiment Nr.3 (9th Replacement Brigade). Prior to November 20, these two regiments were transferred to "Division von Rekowski" (which later became the 39th Bavarian Reserve Division). Kgl. Bayer. Ersatz-Infanterie-Regiment Nr.2 was formed from two battalions of the 5th Mixed Replacement Brigade as well as troops drawn from elsewhere in the Bavarian Army; it was attached to the Bavarian Ersatz Division.
