# XII (1st Royal Saxon) Corps

The XII (1st Royal Saxon) Army Corps / XII AK (German: XII. (I. Königlich Sächsisches) Armee-Korps) was a Saxon corps level command of the Saxon and German Armies before and during World War I.
The Corps was formed as the Royal Saxon Corps on 1 April 1867 and headquartered in Dresden. Initially, it commanded the 1st Royal Saxon Infantry Division in Dresden and the 2nd Royal Saxon Infantry Division in Leipzig. After the XIX (2nd Royal Saxon) Corps was set up on 1 April 1899 as the headquarters for the western part of the Kingdom of Saxony, XII Corps was made responsible for the eastern part of the Kingdom.
The Corps was disbanded with the demobilisation of the German Army after World War I.

## Franco-Prussian War

During the Franco-Prussian War, the corps fought in the Battle of Gravelotte, the Battle of Sedan and the Siege of Paris.

### Order of Battle during the Franco-Prussian War

The organization of the XII (Royal Saxon) Corps on 18 August 1870 at the beginning of the Franco-Prussian War was as follows:
Commander: General Crown Prince Albert of Saxony Chief of the General Staff: Lt. Col. Friedrich von Zezschwitz
* 23rd (1st Royal Saxon) Infantry Division - Lt. General Prince George of Saxony
* 24th (2nd Royal Saxon) Infantry Division - Maj. General Erwin Nehrhoff von Holderberg
* Saxon Cavalry Division - Major General Franz Graf und Edler Herr zur Lippe-Weißenfeld
* 12th (Royal Saxon) Field Artillery Regiment - Col. Bernhard Oskar von Funcke
* 12th (Royal Saxon) Pioneer Battalion - Lt. Col. Karl Hugo Klemm
* 12th (Royal Saxon) Train Battalion - Lt. Col. Edmund Schmalz

## Between the wars

On 1 April 1887 another Saxon division was formed (32nd (3rd Royal Saxon) Infantry Division headquartered in Bautzen) and assigned to the Corps.
As the German Army expanded in the latter part of the 19th Century, the XIX (2nd Royal Saxon) Corps was set up on 1 April 1899 in Leipzig as the Generalkommando (headquarters) for the western part of the Kingdom of Saxony (districts of Leipzig, Chemnitz and Zwickau). It took over command of 24th (2nd Royal Saxon) Division and the newly formed 40th (4th Royal Saxon) Division. Thereafter, XII Corps was responsible for the eastern part of the Kingdom.
The Corps was assigned to the II Army Inspectorate which formed the predominantly Saxon 3rd Army at the start of the First World War.

### Peacetime organisation

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

## Glossary

* Armee-Abteilung or Army Detachment in the sense of "something detached from an Army". It is not under the command of an Army so is in itself a small Army.
* Armee-Gruppe or Army Group in the sense of a group within an Army and under its command, generally formed as a temporary measure for a specific task.
* Heeresgruppe or Army Group in the sense of a number of armies under a single commander.
