Siegfried Freiherr von Forstner began his naval career in April 1930 (his younger brother, Wolfgang-Friedrich, was also a U-boat commander, 37a). He served for more than two years on the light cruiser Nürnberg, including six patrols during the first year of the war. In April 1940 he transferred to the U-boat force. Following standard training he served on U-99 under Kptlt. Kretschmer for one patrol as a Kommandantenschüler (Commander-in-training) (Busch & Röll, 1999).
After a few months on the training boat U-59, in April 1941 he commissioned U-402, a type VIIC U-boat (Busch & Röll, 1999). He operated mostly against convoys in the North Atlantic and became one of the most successful commanders in 1943.
