Korpsabteilung

A Korpsabteilung (engl. Corps Detachment) was a division size infantry formation established by the German Wehrmacht during World War II.

History
During summer and autumn 1943, Wehrmacht suffered heavy losses in men and materiel at the hands of the Red Army on the Eastern Front.  Simultaneously, it had to build-up military strength in France, prior to the expected invasion, and to reinforce the Italian theatre, where the Allies had crossed the Strait of Messina and landed on the Italian mainland at Salerno, and Termoli in September 1943. Therefore, the Replacement Army could no longer generate the replacements to bring up to strength formations that had been depleted in the eastern battles.

In order to preserve the cadres and lineage of the divisions that had suffered heavy losses, to economise on supply and support effort, and probably to give an image of greater strength than really existed, the OKH decided to form Korpsabteilungen on the establishment of infantry divisions, i.e. containing three infantry regiments with two battalions each, an artillery regiment, and divisional troops (reconnaissance, anti-tank, pioneer, medical, and supply battalions). The staff of the Korpsabteilung was created from one of the divisions that were used to create them, while each of the infantry regiments represented one division. They were called Divisionsgruppe (Division Group), and each of the battalions in one of the Divisionsabteilung was called a Regimentsgruppe (Regimental Group). Unlike German infantry divisions, Korpsabteilungen were not numbered but identified by a letter.

Korpsabteilungen were created in three waves, the first and largest one with five Korpsabteilungen (A to F) on 2 November 1943 in Army groups A, Mitte and Süd, a second with Korpsabteilung F in March 1944 at Heeresgruppe A, and the third with Korpsabteilungen G and H at the end of July, early August 1944, after the devastating losses suffered by the Wehrmacht in Operation Bagration.

When it became clear in autumn 1944 that the individual divisions out of which the Korpsabteilungen were built would never be rebuilt due to a lack of manpower, the Korpsabteilungen were renamed as Infanteriedivisionen, and most of them were given the numerical designation of the division that provided the command staff at the time of the formation of the Korpsabteilung.
