The Ersatz Corps (German language: Ersatzkorps) was a corps level command of the German Army that existed briefly at the beginning of World War I.


The Ersatz Corps was formed on 18 August 1914[1] under the command of 6th Army to control the Ersatz divisions of that army (Guards, 4th, 8th, 10th and 19th),[2] hence the name of the Corps. General der Infanterie Ludwig von Falkenhausen was brought out of retirement to take command.[3] Ersatz is German for "replacement". Ersatz divisions were formed on mobilisation from replacement units of active regiments. Each brigade replacement battalion (Brigade-Ersatz-Bataillone) was numbered after its parent infantry brigade, and was formed with two companies each taken from the replacement battalions of the brigade's two infantry regiments. Cavalry Ersatz Abteilungen and Field Artillery Ersatz Abteilungen were likewise formed from active cavalry and field artillery regiments.

Armee-Abteilung Falkenhausen[4] was set up in the southern part of the Western Front in Alsace-Lorraine on 17 September 1914 from the parts of 6th Army that remained in Lorraine after it marched north to participate in the Race to the Sea. The Staff of the Ersatz Corps, and its commander, took command of the Armee-Abteilung and the Ersatz Corps ceased to exist.[5]


The Ersatz Corps was commanded throughout its brief existence by General der Infanterie Ludwig von Falkenhausen.[6][7]
