The XXXXI Reserve Corps ( German : XXXXI. Reserve-Korps / XXXXI RK) was a corps level command of the German Army in World War I.

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]

Structure on formation

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.
