The III Cavalry Corps (German: Höheres Kavallerie-Kommando 3 / HKK 3 literally: Higher Cavalry Command 3) was a formation of the German Army in World War I. The corps was formed on mobilization of the German Army in August 1914 and disbanded in 1919 during the demobilization of the German Army after World War I.
Initially on the Western Front with 7th, 8th and Bavarian Cavalry Divisions preceding 6th Army. Transferred to the East on 9 September 1914 and assigned to 9th Army with just 8th Cavalry Division. Redesignated 20 November 1916 as 57th Corps (z.b.V.).
57th Corps (z.b.V.) was formed on 20 November 1916 by the redesignation of III Cavalry Corps. As the need for large mounted cavalry formations diminished as the war went on, the existing Cavalry Corps increasingly took on the characteristics of a normal Corps Command. This culminated in them being redesignated as "General Commands for Special Use" Generalkommandos zur besonderen Verwendung (Genkdo z.b.V.).
Initially, the Corps simply consisted of 3 Cavalry Divisions (with 2 Jäger battalions attached) without any Corps troops; in supply and administration matters, the Cavalry Divisions were entirely autonomous. The commander was only concerned with tactics and strategy, hence his title of Senior Cavalry Commander Höherer Kavallerie-Kommandeur.
On formation in August 1914, the Corps consisted of:
Each cavalry division consisted of 3 cavalry brigades (6 regiments each of 4 squadrons), a horse artillery Abteilung (3 four-gun batteries), a machine gun detachment (company size, 6 MGs), plus pioneers, signals and a motor vehicle column. A more detailed Table of Organisation and Equipment can be seen here. The Jäger battalions each consisted of 4 light infantry companies, 1 machine gun company (6 MGs), 1 cyclist company and a motorised vehicle column.
The corps was continually redesignated depending upon its role from time to time.
