Personal information
 Kptlt. Günther Heydemann after a patrol. |
Günther Heydemann began his naval career in April 1933. He then sailed on the line ships Schlesien and Schleswig-Holstein before transferring to the U-boat force in April 1940.
After the usual training he made two patrols as watch officer on board U-69 under the command of Kptlt. Jost Metzler.
He left U-69 in April 1941 and two months later commissioned the Type VIIC U-boat U-575.
He commanded this boat on eight relatively successful patrols and sank many ships. In July 1943 he left U-575 and became a training officer in the 23rd and 25th training flotillas until the end of the war.
