[4] With the onset of trench warfare, the German Army recognised that it was no longer possible to maintain the traditional Corps unit, that is, one made up of two divisions.

Therefore, under the Hindenburg regime (from summer 1916), new Corps headquarters were created without organic divisions.

[5] These new Corps were designated General Commands for Special Use (German: Generalkommandos zur besonderen Verwendung).

By the end of the war, the Corps was serving on the Western Front as part of Armee-Abteilung B, Heeresgruppe Herzog Albrecht von Württemberg with the following composition:[6] The units assigned were lower quality Landwehr and Cavalry Schützen Divisions indicative of the relatively quiet sector that the Armee-Abteilung was operating in, on the extreme southern end of the Western Front, to the north of Basel.

The 64th Corps was commanded throughout its existence by General der Kavallerie Wilhelm Karl, Duke of Urach.
