World War I

Battle of the Frontiers

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


IV Reserve Corps was formed on the outbreak of the war in August 1914[1] as part of the mobilisation of the Army. It was initially commanded by General der Artillerie Hans von Gronau, who was recalled from retirement.[2] From 24 July 1916 to 19 December 1917, the Corps was known as Karpathenkorps (Carpathian Corps).[3] The Corps was still in existence at the end of the war[4] as part of the 2nd Army, Heeresgruppe Kronprinz Rupprecht on the Western Front.[5]

Structure on formation

On formation in August 1914, IV Reserve Corps consisted of two divisions, made up of reserve units. In general, Reserve Corps and Reserve Divisions were weaker than their active counterparts

Reserve Infantry Regiments did not always have three battalions nor necessarily contain a machine gun company[6]

Reserve Cavalry Regiments consisted of just three squadrons[8]
Reserve Field Artillery Regiments usually consisted of two abteilungen of three batteries each[9]

In summary, IV Reserve Corps mobilised with 25 infantry battalions, 4 machine gun companies (24 machine guns), 6 cavalry squadrons, 12 field artillery batteries (72 guns) and 3 pioneer companies.
