The Corps was assigned to the VI Army Inspectorate but joined the predominantly Saxon 3rd Army at the start of the First World War.[2] It was still in existence at the end of the war[3] in the 6th Army, HeeresgruppeKronprinz Rupprecht on the Western Front.[4] The Corps was disbanded with the demobilisation of the German Army after World War I.
The 25 peacetime Corps of the German Army (Guards, I - XXI, I - III Bavarian) had a reasonably standardised organisation. Each consisted of two divisions with usually two infantry brigades, one field artillery brigade and a cavalry brigade each.[6] Each brigade normally consisted of two regiments of the appropriate type, so each Corps normally commanded 8 infantry, 4 field artillery and 4 cavalry regiments. There were exceptions to this rule:
V, VI, VII, IX and XIV Corps each had a 5th infantry brigade (so 10 infantry regiments)
On mobilization on 2 August 1914 the Corps was restructured. 38th Cavalry Brigade was withdrawn to form part of the 8th Cavalry Division[10] and the 22nd Cavalry Brigade was withdrawn to form part of the 3rd Cavalry Division.[11] The 6th Cuirassiers, formerly of the III Corps, was raised to a strength of 6 squadrons before being split into two half-regiments of 3 squadrons each. The half-regiments were assigned as divisional cavalry to 22nd and 38th Divisions. Divisions received engineer companies and other support units from the Corps headquarters. In summary, XI Corps mobilised with 25 infantry battalions, 9 machine gun companies (54 machine guns), 6 cavalry squadrons, 24 field artillery batteries (144 guns), 4 heavy artillery batteries (16 guns), 3 pioneer companies and an aviation detachment.
