The XXXXI Reserve Corps (German: XXXXI. Reserve-Korps / XXXXI RK) was a corps level command of the German Army in World War I.
Structure on formation
XXXXI Reserve Corps was formed in December 1914.[1] It was part of the second wave of new Corps formed in the early stages of World War I consisting of XXXVIII - XXXXI[2] Reserve Corps of 75th - 82nd Reserve Divisions (plus 8th Bavarian Reserve Division). The personnel was predominantly made up of kriegsfreiwillige (wartime volunteers) who did not wait to be called up.[3] It was still in existence at the end of the war.[4]
On formation in December 1914, XXXXI Reserve Corps consisted of two divisions.[5] but was weaker than an Active Corps
- the divisions were organised as triangular rather than square divisions with three infantry regiments rather than four, but had a brigade of two field artillery regiments
- Reserve Infantry Regiments consisted of three battalions but lacked a machine gun company[6]
- Reserve Cavalry Detachments were much smaller than the Reserve Cavalry Regiments formed on mobilisation[7]
- Reserve Field Artillery Regiments consisted of two abteilungen (1 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, XXXXI Reserve Corps mobilised with 18 infantry battalions, 2 cavalry detachments, 24 field artillery batteries (96 guns), 2 cyclist companies and 2 pioneer companies.
