Forstner
Siegfried von Forstner celebrates news of his Knights Cross award in the wardroom of U-402, cruising at a depth of 100 ft.

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 boat (Busch & Röll, 1999). He operated mostly against convoys in the North Atlantic and became one of the most successful commanders in 1943.

U-402 was sunk with all hands on 13 October 1943 by an aircraft from the US escort carrier USS Card (Niestlé, 1998).
