TheGuards Corps/GK (German:Gardekorps) was acorps level command of thePrussian and then theImperial German Armies from the 19th century toWorld War I.

The Corps was headquartered inBerlin, with its units garrisoned in the city and nearby towns (Potsdam,Jüterbog,Döberitz). Unlike all other Corps of the Imperial German Army, the Guards Corps did not recruit from a specific area, but from throughoutPrussia and the "Imperial Lands" ofAlsace-Lorraine.

The Corps served in theAustro-Prussian War. During theFranco-Prussian War it was assigned to the 2nd Army.

In peacetime the Corps was assigned to theII Army Inspectorate but joined the2nd Army at the start of theFirst World War.^[1] It was still in existence at the end of the war^[2] in the4th Army,Heeresgruppe Kronprinz Rupprecht, on theWestern Front.^[3] The Corps was disbanded with the demobilisation of the German Army afterWorld War I.

The Guards Corps fought in theAustro-Prussian War againstAustria in 1866, including theBattle of Königgrätz.

The Corps served in theFranco-Prussian War againstFrance in 1870–1871 as part of 2nd Army. It saw action in theBattle of Gravelotte,Battle of Sedan and theSiege of Paris (including theBattle of Le Bourget), among other actions.

The 25 peacetimeCorps of the German Army (Guards, I–XXI, I–III Bavarian) had a reasonably standardised organisation. Each consisted of twodivisions with usually two infantry brigades, one field artillery brigade and a cavalry brigade each.^[4] Each brigade normally consisted of two regiments of the appropriate type, so each Corps normally commanded eight infantry, four field artillery and four cavalry regiments. There were exceptions to this rule:

V,VI,VII,IX andXIV Corps each had a fifth infantry brigade (so 10 infantry regiments)

II,XIII,XVIII andXXI Corps had a ninth infantry regiment

I,VI andXVI Corps had a 3rd cavalry brigade (so six cavalry regiments)

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

The Guards Corps was considerably above this norm, with 11 infantry regiments (in five brigades) and 8 cavalry regiments (in four brigades). In addition to the normal two infantry divisions (1st Guards Infantry and2nd Guards Infantry Divisions), the Guards Corps also commanded theGuards Cavalry Division, the only peacetime cavalry division in the German Army. It also incorporated an exceptional number of "Corps Troops" units, in particular school and demonstration (Lehr) units.

On mobilization on 2 August 1914 the Corps was extensively restructured. TheGuards Cavalry Division (less the 4th Guards Cavalry Brigade) was assigned to theI Cavalry Corps (Höhere Kavallerie-Kommando 1);^[7] the 4th Guards Cavalry Brigade was broken up and its regiments assigned to the divisions as reconnaissance units. TheLehr Infantry Battalion was expanded to form theLehr Infantry Regiment.^[8] It formed 6th Guards Infantry Brigade (with the GuardsFüsilier Regiment) and together with the5th Guards Infantry Brigade formed the3rd Guards Division of theGuards Reserve Corps. Divisions received engineer companies and other support units from the Corps headquarters.

In summary, the Guards Corps mobilised with 26 infantry battalions, 10 machine gun companies (60 machine guns), eight cavalry squadrons, 24 field artillery batteries (144 guns), four heavy artillery batteries (16 guns), three pioneer companies and an aviation detachment.

On mobilisation, the Guards Corps was assigned to the2nd Army as part of the right wing of the forces that invadedFrance andBelgium as part of theSchlieffen Plan offensive in August 1914.

Soon into the war, at theFirst Battle of the Marne, the Prussian Guards were bitterly defeated in an attempt to take French positions.

In early July 1915 it participated in the "Battle of the Guards" near Krasnostav, acting against parts of theRussian Guard corps.^[12][13][14] It participated in the Battle of Lublin-Kholm in July 1915^[15]

In 1917, the corps was stationed on theAisne River as part of1st Army, and played an important role in the German defense against theFrench offensive in that sector.

It was still in existence at the end of the war^[2] in the4th Army,Heeresgruppe Kronprinz Rupprecht, on theWestern Front.^[3]
