X Corps (German Empire)

During the Franco-Prussian War of 1870-71 the army corps fought under the command of General von Voigts-Rhetz in several battles including the Battle of Mars-la-Tour, Battle of Spicheren, Siege of Metz, Battle of Beaune-la-Rolande, Battle of Orléans and Battle of Le Mans.

Due to the large number of Line Infantry regiments then in existence, on 18 December 1890, Kaiser Wilhelm II ordered that the flag colours were to be the same as that of the uniform epaulettes. This was to ensure that each corps attained uniformity. IX and X Corps wore white epaulettes. Notwithstanding this, the flags of the Jäger Battalions would be green.

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. 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)

II, XIII, XVIII and XXI Corps had a 9th infantry regiment

I, VI and XVI Corps had a 3rd cavalry brigade (so 6 cavalry regiments)

the Guards Corps had 11 infantry regiments (in 5 brigades) and 8 cavalry regiments (in 4 brigades).

Each Corps also directly controlled a number of other units. This could include one or more

Foot Artillery Regiment

Jäger Battalion

Pioneer Battalion

Train Battalion

Organisation on mobilisation

On mobilization on 2 August 1914 the Corps was restructured. 19th Cavalry Brigade was withdrawn to form part of the 9th Cavalry Division and the 20th Cavalry Brigade was broken up. The 17th (Brunswick) Hussars 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 19th and 20th Divisions. Likewise, the 16th (2nd Hannover) Dragoons formed two half-regiments which were assigned as divisional cavalry to 17th and 18th Divisions of IX Corps. Divisions received engineer companies and other support units from the Corps headquarters. In summary, X 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.

Combat chronicle

On mobilisation, X Corps was assigned to the 2nd Army forming part of the right wing of the forces for the Schlieffen Plan offensive in August 1914 on the Western Front.

It was still in existence at the end of the war in Armee-Abteilung B, Heeresgruppe Herzog Albrecht von Württemberg at the extreme southern end of the Western Front.

The X Corps had the following commanders during its existence:
