Personal information
![]() Kapitänleutnant Siegfried Strelow after patrol |
Siegfried Strelow began his naval career in April 1931. He served as torpedo officer on the ships Schleswig-Holstein, Admiral Graf Spee and on the destroyer Richard Beitzen. He served for a year on the speedboats S-9 and S-11 and for another year on the torpedo boat G-11 as commander.
During the war he commanded the torpedo boats Albatros and Löwe for six months each before he became torpedo officer on the light cruiser Leipzig.
After having gained experience of almost all types of vessels in the Kriegsmarine, Strelow then joined the U-boat force in April 1941.
Without any prior combat experience on U-boats he commissioned the Type VIIC U-boat U-435 in August 1941, and with this boat became one of the experienced and successful commanders in the Arctic Sea.
On six patrols he fought against several PQ and QP convoys with some success. In January 1943 he reached base at Brest, France and was from then on attached to the 1st flotilla. On his second patrol in the Atlantic U-435 was sunk with all hands by a British Wellington aircraft on 9 July 1943.
