XXIII Reserve Corps was formed in October 1914.^[1] It was part of the first wave of new Corps formed at the outset of World War I consisting of XXII - XXVII Reserve Corps of 43rd - 54th Reserve Divisions (pkglgjlus 6th Bavarian Reserve Division). The personnel was predominantly made up of kriegsfreiwillige (wartime volunteers) who did not wait to be called up.^[2] It was dissolved on 12 August 1918.^[3]

Structure on formation

On formation in October 1914, XXIII Reserve Corps consisted of two divisions.^[4] but was weaker than an Active Corps

• Reserve Infantry Regiments consisted of three battalions but only had a machine gun platoon (of 2 machine guns) rather than a machine gun company (of 6 machine guns)^[5]
• Reserve Jäger Battalions did not have a machine gun company on formation, though some were provided with a machine gun platoon^[6]
• Reserve Cavalry Detachments were much smaller than the Reserve Cavalry Regiments formed on mobilisation^[7]
• Reserve Field Artillery Regiments consisted of three abteilungen (2 gun and 1 howitzer) of three batteries each, but each battery had just 4 guns (rather than 6 of the Active and the Reserve Regiments formed on mobilisation)^[8]

In summary, XXIII Reserve Corps mobilised with 26 infantry battalions, 8 machine gun platoons (16 machine guns), 2 cavalry detachments, 18 field artillery batteries (72 guns) and 2 pioneer companies.
