Befehlshaber der Unterseeboote - BdU
(C-in-C U-boats)

The post of BdU was created on 19 September 1939, Karl Dönitz assuming the new title (and promotion to Konteradmiral)
after relinquishing the previously held post of FdU (Führer der Unterseeboote). Although later promoted to become the head of the Kriegsmarine as a whole (February 1943), Dönitz never stepped down as BdU. In May 1945 Dönitz was named as Head of the German State in Hitler's will, at which time the title of Oberbefehlshaber der Kriegsmarine was handed to KA Hans Georg von Friedeburg - by then an almost academic decision.

BdU command was divided into two spheres - organisational and operational.

BdU (Org) was headed by KA Hans Georg von Friedeburg, while KA Eberhard Godt headed BdU (Ops) - from March 1943 known as Unterseebootsführungs Abteilung (2/SKL BdU Op).
