Otto Niethmann joined the Kriegsmarine in 1938. He underwent U-boat training Oct 1940 - May 1941 and then served as a Watch Officer (WO) on U-30 May 1941 - March 1942 (Busch & Röll, 1999).
From March to Aug 1942 Niethmann served as a Watch Officer on U-373 (Kptlt. Paul-Karl Loeser) (Busch & Röll, 1999). He went on one patrol from 18 May to 8 July, during which one small ship of 396 tons was sunk.
Niethmann commanded the small 'duck' training boat U-6 from 20 Oct 1942 to July 1943, when he began U-boat construction familiarization (Baubelehrung) of his next command, a new type VIIC U-boat. He commissioned U-476 at Kiel on 28 July 1943 (Busch & Röll, 1999). After some months working up in the Baltic, U-476 arrived in Norway for active service in April 1944, and left for her first and only combat patrol on 20 May 1944 (Busch & Röll, 1997).
Surviving two U-boat losses in two days
Oblt. Niethmann was forced to scuttle U-476 on 24 May 1944 due to crippling damage caused by a British Catalina flying boat (Sqdn 210/V) (Niestlé, 1998). Kplt. Hubert Nordheimer's U-990 rescued 21 men from U-476, but 34 of her crew went down with the boat (Blair, 1998).
The German picket boat V 5901 rescued 51 men from the sinking U-990, including 18 of the original 21 from U-476. 33 from U-990's crew were rescued, but 20 perished. (Niestlé, 1998) Oblt. Niethmann and Kplt. Nordheimer survived, and both eventually returned to Germany to take command of new type XXI Elektro U-boat Elektro boats (Blair, 1998).
Oblt. Niethmann served with 11th Flotilla from May to July 1944 before returning to Germany to commence type XXI U-boat familiarization (Baubelehrung). He finished his training and commissioned U-3507 at the Schichau yard in Danzig on 19 Oct 1944. (Busch & Röll, 1999) He spent the winter training in the Baltic, only to scuttle U-3507 at Travemünde on 3 May 1945 (Niestlé, 1998). For the last few days of the war he served in the 5th (Training) Flotilla at Kiel.
